The Ultimate Fighting Championship (UFC) is an American mixed martial arts (MMA) promotion company based in Las Vegas, Nevada. It is owned and operated by TKO Group Holdings, a majority owned subsidiary of Endeavor Group Holdings. It is the largest MMA promotion in the world as of 2023. It produces events worldwide that showcase 11 weight divisions (eight men's and three women's) and abides by the Unified Rules of Mixed Martial Arts. As of 2022, it had held over 600 events. Dana White has been its president since 2001 and CEO since 2023. Under White's stewardship, it has grown into a global multi-billion-dollar enterprise.

The UFC was founded by businessman Art Davie and Brazilian martial artist Rorion Gracie, and the first event was held in 1993 at the McNichols Sports Arena in Denver, Colorado. The purpose of the UFC's early competitions was to identify the most effective martial art in a contest with minimal rules and no weight classes between competitors of different fighting disciplines. In subsequent events, more rigorous rules were created and fighters began adopting effective techniques from more than one discipline, which indirectly helped create a separate style of fighting known as present-day mixed martial arts.

The UFC was initially owned by the Semaphore Entertainment Group (SEG) until it had financial issues and it was sold to the brothers Frank and Lorenzo Fertitta in 2001, who formed the company Zuffa to operate the UFC, and placed Dana White as the president of the company. In 2016, UFC's parent company, Zuffa, was sold to a group led by Endeavor, then known as William Morris Endeavor (WME–IMG), including Silver Lake Partners, Kohlberg Kravis Roberts and MSD Capital for US$4.025 billion. In 2021, Endeavor bought out Zuffa's other owners at a valuation of $1.7 billion. The organization had 578 fighters contracted as of January 2023.

With a TV deal and expansion in Australia, Asia, Europe, and new markets within the United States, the UFC has achieved greater mainstream media coverage. It earned US$609 million in 2015, and its next domestic media rights agreement with ESPN was valued at $1.5 billion over a five-year term.

In April 2023, Endeavor Group Holdings announced that UFC would merge with the wrestling promotion WWE to form TKO Group Holdings, a new public company majority-owned by Endeavor, with Vince McMahon serving as an executive chairman of the new entity and White remaining as UFC president. The merger was completed on September 12, 2023.

History

Early 1990s competition

Royce Gracie used Brazilian jiu-jitsu in the early years of UFC to defeat opponents of greater size and strength.

Art Davie proposed to John Milius and Rorion Gracie an eight-man single-elimination tournament called "War of the Worlds". It was inspired by the "Gracies in Action" video-series produced by the Gracie family of Brazil which featured Gracie jiu-jitsu students defeating martial artists of various disciplines such as karate, kung fu, and kickboxing on Vale Tudo matches. The tournament would also feature martial artists from different disciplines facing each other in no-holds-barred combat to determine the best martial art, and would aim to replicate the excitement of the matches Davie saw on the videos. Gracie accepted, as he was interested in showcasing and promoting his family's own jiu-jitsu for a wide audience. Milius, a film director/screenwriter and Gracie student, agreed to be the event's creative director. Davie drafted the business plan, and 28 investors contributed the initial capital to start WOW Promotions to develop the tournament into a television franchise.

In 1993, WOW Promotions sought a television partner and approached pay-per-view producers TVKO (HBO) and SET (Showtime), and Campbell McLaren and David Isaacs at Semaphore Entertainment Group (SEG). Both TVKO and SET declined, but SEG—a pioneer in pay-per-view television that had produced such offbeat events as a tennis match between Jimmy Connors and Martina Navratilova—became WOW's partner in May 1993. UFC promoters initially pitched the event as a real-life fighting video game tournament similar to Street Fighter and Mortal Kombat. SEG contacted video and film art director Jason Cusson to design a fighting arena for the event. Rorion and Davie didn't want a traditional roped ring, citing fears—by showing old Vale Tudo footage—that the fighters could escape through the ropes during grappling and use it as an advantage, or fall off and hurt themselves. SEG's executives agreed, and also wanted a way to visually differentiate their event from professional boxing and professional wrestling. Some ideas included a traditional roped-ring surrounded by netting, a moat with alligators, a raised platform surrounded by razor-wire fence, electrified fencing, men in togas and netting that could be lowered from the ceiling by a pulley. Eventually Cusson designed an arena with eight sides surrounded by chain-link fence, the trademarked Octagon, which became the event's signature setting. Cusson remained the group's production designer through UFC 27. SEG devised the show's name as "The Ultimate Fighting Championship".

WOW Promotions and SEG produced the first event, later retroactively called UFC 1, at McNichols Sports Arena in Denver, Colorado on November 12, 1993. Art Davie was its booker and matchmaker. It proposed to find answers for sports fans' questions such as, "Can a wrestler beat a boxer?" As with most martial arts at the time, fighters typically had skills in just one discipline and little experience against opponents with differing skills. The television broadcast featured kickboxer Kevin Rosier, taekwondo practitioner Patrick Smith, savate fighter Gerard Gordeau, karate expert Zane Frazier, shootfighter Ken Shamrock, sumo wrestler Teila Tuli, boxer Art Jimmerson, and 175 lb (79 kg) Brazilian jiu-jitsu black belt Royce Gracie—younger brother of UFC co-founder Rorion, whom Rorion selected to represent his family. Royce's submission skills proved the most effective in the inaugural tournament, earning him the first ever UFC tournament championship after submitting Jimmerson, Shamrock, and Gordeau in succession. The show was extremely successful, with 86,592 pay-per-view television subscribers.

It's disputed whether the promoters intended the event to be a precursor to future events. "That show was only supposed to be a one-off", eventual UFC president Dana White said. "It did so well on pay-per-view they decided to do another, and another. Never in a million years did these guys think they were creating a sport." Davie, in his 2014 book Is This Legal?, an account of the creation of the first UFC event, disputes the perception that the UFC was seen by WOW Promotions and SEG as a one-off, since SEG offered a five-year joint development deal to WOW. He says, "Clearly, both Campbell and Meyrowitz shared my unwavering belief that War of the Worlds would be a continuing series of fighting tournaments—a franchise, rather than a one-night stand."

With no weight classes, fighters often faced significantly larger or taller opponents. Keith "The Giant Killer" Hackney faced Emmanuel Yarbrough at UFC 3 with a 9-inch height and 400 pounds (180 kg) weight disadvantage.

During this early phase of the organization, the UFC showcased a bevy of styles and fighters. Aside from the aforementioned Royce Gracie, Ken Shamrock, and Patrick Smith, they also featured competitors such as Hall of Famer Dan Severn, Marco Ruas, Gary Goodridge, Don Frye, Kimo Leopoldo, Oleg Taktarov, and Tank Abbott.

In April 1995, following UFC 5 in Charlotte, North Carolina, Davie and Gracie sold their interest in the franchise to SEG and disbanded WOW Promotions.

Tightening up of the rules

Although UFC used the tagline "There are no rules" in the early 1990s, the UFC did in fact operate with limited rules. In a UFC 4 qualifying match, competitors Jason Fairn and Guy Mezger agreed not to pull hair—as they both wore pony tails tied back for the match. The UFC had a reputation, especially in the early days, as an extremely violent event.

UFC 5 also introduced the first singles match, a rematch from the inaugural UFC featuring three-time champion Royce Gracie and Ken Shamrock, called "The Superfight". "The Superfight" began as a non-tournament match that would determine the first reigning UFC Champion for tournament winners to face; it later evolved into a match that could feature either title matches or non-title matches. The "Superfight" would eventually completely phase out tournament matches.

On the other hand, the first "Superfight" at UFC 5 was also considered a failure. In the first minute of the fight Shamrock knocked Royce to the ground and landed inside his guard. For the next 30 minutes Shamrock was inside Royce's guard, with the two throwing punches and headbutts at each other but without any change or action, with the crowd booing the fighters. After 30 minutes the fight was stopped as it had exceeded the time limit allocated for the pay-per-view and was given another 5 minutes of extra time due to protests from the spectators. The fight was over after 36 minutes and a draw was declared. Because of this controversial fight, the UFC would later start to introduce time limits, judges to decide draws, and authorized referees to stand up fighters and restart the bout if they have too much inactivity.

In 1996, the UFC had its first event outside continental United States with UFC 8 in Bayamón, Puerto Rico, and in 1997, UFC Japan: Ultimate Japan was its first foreign event.

Late 1990s controversy and reform

The violent nature of the burgeoning sport quickly drew the attention of U.S. authorities.

In 1996, U.S. Senator John McCain saw a tape of the first UFC events and immediately found it abhorrent. He led a campaign to ban the UFC, calling it "human cockfighting", and sent letters to the governors of all 50 US states asking them to ban it.

36 states enacted laws that banned "no-holds-barred" fighting, including New York, which enacted the ban on the eve of UFC 12, forcing it to relocate to Dothan, Alabama. The UFC continued to air on DirecTV PPV, though its audience remained minuscule compared to the era's larger cable pay-per-view platforms.

In response to the criticism, the UFC increased cooperation with state athletic commissions and modified its rules to remove the less palatable elements of fights while retaining the core elements of striking and grappling. UFC 12 saw the introduction of weight classes and the banning of fish-hooking. For UFC 14, gloves became mandatory, while kicks to the head of a downed opponent were banned. UFC 15 saw limitations on hair pulling, and the banning of strikes to the back of the neck and head, headbutting, small-joint manipulations, and groin strikes. With five-minute rounds introduced at UFC 21, the UFC gradually rebranded itself as a sport rather than a spectacle.

Led by UFC commissioner Jeff Blatnick and referee John McCarthy, the UFC continued to work with state athletic commissions. Blatnick, McCarthy, and matchmaker Joe Silva created a manual of policies, procedures, codes of conduct, and rules to help in getting the UFC sanctioned by the athletic commissions, many of which exist to this day. Blatnick and McCarthy traveled around the country, educating regulators and changing perceptions about a sport that was thought to be bloodthirsty and inhumane. By April 2000, their movement had clearly made an impact. California was set to become the first state in the U.S. to sign off on a set of codified rules that governed MMA. Soon after, New Jersey adopted the language.

As the UFC continued to work with the athletic commissions, events took place in smaller U.S. markets, and venues, such as the Lake Charles Civic Center. The markets included states that are largely rural and less known for holding professional sporting events, such as Iowa, Mississippi, Louisiana, Wyoming, and Alabama. SEG could not secure home-video releases for UFC 23 through UFC 29. With other mixed martial arts promotions working towards U.S. sanctioning, the International Fighting Championships (IFC) secured the first U.S. sanctioned mixed martial arts event, which occurred in New Jersey on September 30, 2000. Just two months later, the UFC held its first sanctioned event, UFC 28, under the New Jersey State Athletic Control Board's "Unified Rules".

2001 and the beginning of Zuffa era

After the long battle to secure sanctioning, SEG stood on the brink of bankruptcy, when Station Casinos executives Frank and Lorenzo Fertitta and their business partner Dana White approached them in 2000, with an offer to purchase the UFC. A month later, in January 2001, the Fertittas bought the UFC for $2 million and created Zuffa, LLC as the parent entity controlling the UFC.

"I had my attorneys tell me that I was crazy because I wasn't buying anything. I was paying $2 million and they were saying 'What are you getting?'" Lorenzo Fertitta revealed to Fighters Only magazine, recalling the lack of assets he acquired in the purchase. "And I said 'What you don't understand is I'm getting the most valuable thing that I could possibly have, which is those three letters: UFC. That is what's going to make this thing work. Everybody knows that brand, whether they like it or they don't like it, they react to it.'" Along with the trademark, they acquired a wooden octagon and around a dozen fighter's contracts. Later on, they negotiated a deal to buy UFC's DVD rights from Lionsgate for an additional two million dollars.

With ties to the Nevada State Athletic Commission (Lorenzo Fertitta was a former member of the NSAC), Zuffa secured sanctioning in Nevada in 2001. Shortly thereafter, the UFC returned to pay-per-view cable television, with UFC 33 featuring three championship bouts.

Struggle for survival and turnaround

The UFC slowly rose in popularity after the Zuffa purchase, due partly to greater advertising, corporate sponsorship, the return to cable pay-per-view, and subsequent home video and DVD releases.

With larger live gates at casino venues like the Trump Taj Mahal and the MGM Grand Garden Arena, the UFC secured its first television deal with Fox Sports Net. The Best Damn Sports Show Period aired the first mixed martial arts match on American cable television in June 2002, as well as the main event showcasing Chuck Liddell vs. Vitor Belfort at UFC 37.5. Later, FSN would air highlight shows from the UFC.

UFC Hall of Famer Ken Shamrock was instrumental in the UFC's turnaround into a mainstream sport.

UFC 40 proved to be the most critical event to date in the Zuffa era. The event was a near sellout of 13,022 at the MGM Grand Arena and sold 150,000 pay-per-view buys, a rate roughly double that of the previous Zuffa events. The event featured a card headlined by a championship match between then-current UFC Light Heavyweight Champion Tito Ortiz and former UFC Superfight Champion Ken Shamrock, who had previously left to professionally wrestle in WWE before returning to MMA. It was the first time the UFC hit such a high mark since being forced "underground" in 1997. UFC 40 also garnered mainstream attention from media outlets such as ESPN and USA Today, something that was unfathomable for mixed martial arts at that point in time. Many have suggested that the success of UFC 40 and the anticipation for Ortiz vs. Shamrock saved the UFC from bankruptcy; the buyrates of the previous Zuffa shows averaged a mere 45,000 buys per event, and the company was suffering deep monetary losses. The success of UFC 40 provided a glimmer of hope for the UFC, and kept alive the hope that mixed martial arts could become big. Beyond the rivalry itself, the success of UFC 40 was due in part to the marketing and outreach power of crossover athletes – from Pro Wrestling to MMA and MMA to Pro Wrestling – a practice with roots in Japan's Pride Fighting Championships. Long time UFC referee John McCarthy said that he felt UFC 40 was the turning point in whether or not the sport of MMA would survive in America.

"When that show (UFC 40) happened, I honestly felt like it was going to make it. Throughout the years, things were happening, and everything always looked bleak. It always looked like, this is it, this is going to be the last time. This is going to be the last year. But, when I was standing in the Octagon at UFC 40, I remember standing there before the Ortiz/Shamrock fight and looking around. The energy of that fight, it was phenomenal, and it was the first time I honestly said, it's going to make it." –"Big" John McCarthy

Despite the success of UFC 40, the UFC was still experiencing financial deficits. By 2004, Zuffa had $34 million in losses since they purchased the UFC.

The Ultimate Fighter and the rise in popularity

Faced with the prospect of folding, the UFC stepped outside the bounds of pay-per-view and made a foray into television. After being featured in a reality television series, American Casino, and seeing how well the series worked as a promotion vehicle, the Fertitta brothers developed the idea of UFC creating its own reality series.

Their idea, The Ultimate Fighter (TUF), was a reality television show featuring up-and-coming MMA fighters in competition for a six-figure UFC contract, with fighters eliminated from competition via exhibition mixed martial arts matches. It was pitched to several networks, each one rejecting the idea outright. Not until they approached Spike TV, with an offer to pay the $10 million production costs themselves, did they find an outlet.

In January 2005, Spike TV launched The Ultimate Fighter 1 (TUF 1) in the timeslot following WWE Raw. The show became an instant success, culminating with a notable season finale brawl featuring light heavyweight finalists Forrest Griffin and Stephan Bonnar going toe-to-toe for the right to earn the six-figure contract. The live broadcast of the season finale drew a very impressive 1.9 overall rating. Dana White credits TUF 1 for saving the UFC, and claims that the contract for the second season was made outside of the venue on a napkin immediately after the finale.

On the heels of the Griffin/Bonnar finale, a second season of The Ultimate Fighter launched in August 2005, and two more seasons appeared in 2006. Spike and the UFC continued to create and air new seasons until the show moved to FX in 2012.

Following the success of The Ultimate Fighter, Spike also picked up UFC Unleashed, an hour-long weekly show featuring select fights from previous events. Spike also signed on to broadcast live UFC Fight Night, a series of fight events debuting in August 2005, and Countdown specials to promote upcoming UFC pay-per-view cards.

After a very successful run on Spike and with the upcoming announcement of the UFC's new relationship with Fox, Spike officials made a statement regarding the end of their partnership with the UFC, "The Ultimate Fighter season 14 in September will be our last... Our 6-year partnership with the UFC has been incredibly beneficial in building both our brands, and we wish them all the best in the future."

With the announcement of UFC's partnership with Fox in August 2011, The Ultimate Fighter, which entered its 14th season in that September, moved to the FX network to air on Friday nights starting with season 15 in the Spring of 2012. Along with the network change, episodes are now edited and broadcast within a week of recording instead of a several-month delay, and elimination fights are aired live.

Mid-2000s expansion

With increased visibility, the UFC's pay-per-view buy numbers exploded. UFC 52, the first event after the first season of The Ultimate Fighter featuring eventual-UFC Hall of Famer: Chuck "The Iceman" Liddell, avenging his defeat to fellow eventual-Hall of Famer, Randy Couture, drew a pay-per-view audience of 300,000, doubling its previous benchmark of 150,000 set at UFC 40. Following the second season of The Ultimate Fighter, the UFC's match between Liddell and Couture drew an estimated 410,000 pay-per-view buys at UFC 57.

For the rest of 2006, pay-per-view buy rates continued to skyrocket, with 620,000 buys for UFC 60: Hughes vs. Gracie —featuring Royce Gracie's first UFC fight in 11 years—and 775,000 buys for UFC 61 featuring the highly anticipated rematch between Ken Shamrock and Tito Ortiz, the coaches of The Ultimate Fighter 3. The organization hit a milestone with UFC 66, pitting Ortiz in a rematch against Liddell with over 1 million buys.

The surge in popularity prompted the UFC to beef up its executive team. In March 2006, the UFC announced that it had hired Marc Ratner, former executive director of the Nevada Athletic Commission, as Vice President of Regulatory Affairs. Ratner, once an ally of Senator McCain's campaign against no holds barred fighting, lobbied numerous athletic commissions to help raise the UFC's media profile in an attempt to legalize mixed martial arts in jurisdictions inside and outside the United States that had yet to sanction the sport.

In December 2006, Zuffa acquired the northern California-based promotion World Extreme Cagefighting (WEC) in order to stop the International Fight League (IFL) from making a deal with Versus (now NBC Sports Network). At the time, the UFC had an exclusive deal with Spike, so the purchase of the WEC allowed Zuffa to block the IFL from Versus without violating their contract. The WEC showcased lighter weight classes in MMA, whereas the UFC featured heavier weight classes.

In December 2006, Zuffa also acquired their cross-town, Las Vegas rival World Fighting Alliance (WFA). The WFA had signed major fighters at the time, most notably Quinton "Rampage" Jackson and Lyoto Machida, but their events turned out to be a financial disaster. Zuffa bought select assets from WFA, including select fighter contracts, as well as trademarks and other intellectual property.

The sport's popularity was also noticed by the sports betting community as BodogLife.com, an online gambling site, stated in July 2007 that in 2007 UFC would surpass boxing for the first time in terms of betting revenues. In fact, the UFC had already broken the pay-per-view industry's all-time records for a single year of business, generating over $222,766,000 in revenue in 2006, surpassing both WWE and boxing.

The UFC continued its rapid rise from near obscurity with Roger Huerta gracing the cover of Sports Illustrated and Chuck Liddell on the front of ESPN The Magazine in May 2007.

Pride acquisition and integration

In Japan, Mixed Martial Arts took a separate, yet convergent evolution, with origins in "shoot wrestling", a form of professional wrestling which had more realistic-looking moves and matches while deemphasizing theatrical elements. Promotions like Shooto and Pancrase discarded the scripts and were already putting on hybrid fighting shows with real fights by the time the UFC was founded. This culminated in the creation of Pride Fighting Championships in 1997. At its height, Pride was the world's most popular MMA promotion, and helped to popularize the sport in Japan and in the world. Having high attendances on large sports arenas and watched by millions of spectators through free-to-air and pay-per-view television. Meanwhile, the UFC was struggling with political persecution, low pay-per-view sales, and doing events in backwater casinos. Most of UFC's best fighters would leave to fight in Japan instead due better pay and prestige.

However, on 2006, Pride started to have financial issues due the termination of lucrative contracts with Japanese TV due a scandal revealing the strong ties between Pride and the yakuza. On March 27, 2007, the UFC and Pride announced an agreement in which the majority owners of the UFC, Frank and Lorenzo Fertitta, would purchase the Pride brand.

Initial intentions were for the organizations to be run separately but aligned together with plans to co-promote cards featuring the champions and top contenders from both organizations, making comparisons to the AFL–NFL merger and the creation of a "Super Bowl" of MMA. However, after purchasing Pride, Dana White felt that the Pride model was not sustainable and that the brand became "toxic" in Japan, being difficult to find a new television deal. The organization instead folded, with many former Pride fighters such as Antônio Rodrigo "Minotauro" Nogueira, Maurício "Shogun" Rua, Dan Henderson, Mirko "Cro Cop" Filipović, Wanderlei Silva, and others already being realigned under the UFC brand. On October 4, 2007, Pride Worldwide closed its Japanese office, laying off 20 people who were working there since the closing of its parent company Dream Stage Entertainment (DSE).

On June 18, 2008, Lorenzo Fertitta accommodated the UFC's growth by announcing his resignation from Station Casinos in order to devote his energies to the international business development of Zuffa, particularly the UFC. The move proved to be pivotal, as Fertitta helped strike TV deals in China, France, Mexico, and Germany as well as open alternative revenue streams with a new UFC video game and UFC action figures, among other projects.

Late 2000s–mid-2010s growth with UFC 100

Popularity surged in 2009 with UFC 100 and the 10 events preceding it including UFC 90, 91, 92, 94, and 98. UFC 100 was a success, garnering 1.6 million buys under the drawing power of former NCAA wrestling and WWE Champion Brock Lesnar and his rematch with former UFC Heavyweight Champion Frank Mir, Canadian Georges St-Pierre going head-to-head with Brazilian Thiago Alves, and American Dan Henderson opposing British Michael Bisping at middleweight after the two were rival coaches on The Ultimate Fighter: United States vs. United Kingdom.

UFC 100 drew interest from ESPN, which provided coverage of the event in the days preceding and following it. ESPN would eventually devote additional coverage of the UFC and other MMA news with the television debut of MMA Live on ESPN2 in May 2010.

The buzz from UFC 100 was hampered significantly in the second half of 2009 after a rash of injuries and other health-related issues—including Brock Lesnar's life-threatening bout with diverticulitis—forcing the organization to continuously scramble and reshuffle its lineup for several events.

However, the momentum gradually began to pick up in the first quarter of 2010 after victories from defending champions Georges St-Pierre and Anderson Silva, as well as Lyoto Machida's first career defeat to "Shogun" Rua for the UFC Light Heavyweight title. These fights segued into a very popular clash between former UFC Champions and rivals Rashad Evans and Quinton Jackson—rival coaches on The Ultimate Fighter 10: Heavyweights—at UFC 114, featuring the UFC's first main event headlined by black fighters. The event scored over 1 million pay per view buys as Evans secured a unanimous decision victory.

UFC 129 shattered previous North American gate and attendance records.

This momentum carried into the summer of 2010 at UFC 116, which featured the return of Brock Lesnar defending his UFC Heavyweight title against the undefeated interim-champion Shane Carwin before 1.25 million PPV viewers. Lesnar survived an early barrage of Carwin's punches in a contest that was nearly stopped by referee Josh Rosenthal. However, Lesnar recovered in the second round to submit Carwin via arm-triangle choke to retain the undisputed UFC Heavyweight Championship. The event as a whole was critically acclaimed in the media for living up to the hype with a number of exciting fights.

After a fifth round, last-minute victory by UFC Middleweight Champion Anderson Silva over Chael Sonnen at UFC 117, Lesnar finally surrendered his belt to the undefeated Cain Velasquez via 1st-round TKO at UFC 121. The fight produced Velasquez's eighth knockout or technical knockout in his first nine MMA fights.

UFC 129 featured Georges St-Pierre vs. Jake Shields at the Rogers Centre in Toronto, Ontario, Canada and is currently the largest UFC event in North American history, which coincided with a two-day UFC Fan Expo at the Direct Energy Centre. The event sold out 55,000 tickets for gate revenues exceeding $11 million, shattering previous MMA attendance and gate records in North America.

On November 5, 2016, the UFC had their first exhibition in New York City after years of being delayed by government officials and red tape with a dramatic first match, Conor McGregor vs. Eddie Alvarez.

WEC merger

Anthony Pettis weighs in for the final WEC event

Zuffa, the parent company of the UFC, purchased World Extreme Cagefighting in late 2006 and held the first WEC event under new ownership on January 20, 2007. Soon thereafter the WEC made its home on the Versus Network with its first event debuting on that network in June 2007.

On October 28, 2010, Zuffa announced that WEC would merge with the UFC. The WEC held its final card on December 16, 2010. As a result of the merger, the UFC absorbed WEC's bantamweight, featherweight and lightweight weight divisions and their respective fighters. The UFC also made the last WEC Featherweight and Bantamweight Champions, José Aldo and Dominick Cruz respectively, the inaugural UFC Champions of their new weight divisions.

Reed Harris, who started World Extreme Cagefighting with Scott Adams, had mixed emotions on the merger. "It's kind of like when your kid goes off to college: at first you're not happy, but after you think about it for a while, you're really happy," Harris said following the announcement. "At the end of the day, I never imagined this thing would be where we're at today. I'm extremely proud and happy that I was involved with something that will now be part of what may be, some day, the largest sports organization in the world."

Strikeforce purchase

The Strikeforce cage

On March 12, 2011, Dana White announced that Zuffa had purchased Strikeforce. White said that Strikeforce will operate as an independent promotion, and that CEO Scott Coker will continue to run the promotion. Coker announced the return of Fedor Emelianenko on an unspecified July or August event and said that Zuffa-owned company would continue to co-promote with M-1 Global. After an extension was reached to continue Strikeforce through 2012, the promotion's heavyweight division (sans Heavyweight Grand Prix finalists) was merged into the UFC, and the promotion's Challengers series was ended.

The final Strikeforce show was Strikeforce: Marquardt vs. Saffiedine on January 12, 2013, after which the promotion was dissolved and all fighter contracts were either ended or absorbed into the UFC.

On August 18, 2011, The Ultimate Fighting Championship and Fox announced a seven-year broadcast deal through the Fox Sports subsidiary, effectively ending the UFC's Spike TV and Versus (now NBC Sports Network) partnership. The deal includes four events on the main Fox network, 32 live Friday night fights per year on their cable network FX, 24 events following The Ultimate Fighter reality show and six separate Fight Night events.

The promotion's first broadcast television event – UFC on Fox: Velasquez vs. dos Santos – broke form by showcasing only one fight to television viewers. In the main event, Junior dos Santos abruptly dethroned then-undefeated UFC heavyweight champion Cain Velasquez by knock-out at 1:04 in the first round. The telecast peaked with 8.8 million viewers tuning into the fight with an average audience of 5.7 million, making it by far the most-watched MMA event of all-time and the most-watched combat sports event since 2003's HBO bout between Lennox Lewis and Vitali Klitschko.

One of the other programming opportunities that emerged was a weekly UFC magazine-style show. When asked about potential for a weekly magazine-style series, UFC CEO Lorenzo Fertitta responded, "Not only weekly, but potentially, multiple times per week you'll have a UFC magazine (show)." The UFC maintained production control of its product including use of its broadcast team, Mike Goldberg and Joe Rogan. Fox Sports produced pre- and post-shows.

Women's MMA

Ronda Rousey was the first female UFC champion. She defended her 135-pound Bantamweight Championship from February 23, 2013, to November 15, 2015.

On November 16, 2012, the eve of UFC 154: St. Pierre vs. Condit, Dana White confirmed the UFC would feature women's MMA with the signing of its first female fighter, Strikeforce bantamweight champion Ronda Rousey. She subsequently became the first female UFC champion, the first Olympic medalist with a UFC title, and the first woman to defend a UFC title. She would successfully defend her title six times.

On December 11, 2013, the UFC purchased the contracts of 11 female fighters from Invicta Fighting Championships to launch their 115-pound Strawweight division. Eight of the Invicta fighters took part in the 20th season of The Ultimate Fighter, The Ultimate Fighter: Team Pettis vs. Team Melendez, along with eight additional fighters signed up for the tournament via open tryouts. Season winner, Invicta FC's Strawweight Champion, Carla Esparza became the first UFC women's strawweight champion, defeating Rose Namajunas in the finale. Other fighters on the show included Felice Herrig, Tecia Torres, Joanne Calderwood, Bec Hyatt, Randa Markos, Jessica Penne, and Joanna Jędrzejczyk.

International expansion

The first UFC event to be held outside the contiguous United States was UFC 8 in Puerto Rico, a US territory, in 1996.

Canada has hosted events 18 times, starting with UFC 83 in 2008 and most recently in 2015 with UFC 186. UFC's biggest event to date was also in Canada, as UFC 129 held at Rogers Centre featured a record-breaking attendance of 55,724.

The United Kingdom has been home to 16 events. The first was UFC 38 held in London in 2002. UFC returned to the United Kingdom in 2007 with UFC 70, and visited Northern Ireland for UFC 72.

Poland had its first event with UFC Fight Night: Gonzaga vs. Cro Cop 2 in 2015.

The first Brazilian event was UFC Brazil: Ultimate Brazil, held in São Paulo in 1998. The promotion did not return to Brazil until 2011 for UFC 134, but since then, the country has hosted a further 20 events. Their most recent visit was UFC Fight Night: Condit vs. Alves. In 2014, Mexico became the second country in Latin America to host an event with UFC 180, followed by a second event, UFC 188, in 2015.

Seven UFC events have been held in Australia, beginning with UFC 110 in 2010 and most recently in December 2018 with UFC Fight Night 142. New Zealand held its first event in 2014, UFC Fight Night: Te Huna vs. Marquardt. Its most recent event was UFC Fight Night: Felder vs. Hooker in February 2020.

In Asia, the UFC has visited 5 countries. Japan had its first visit in 1997 for UFC Japan: Ultimate Japan. The UFC only returned to the country in 2012, with UFC 144. Their last visit was in 2014 for UFC Fight Night: Hunt vs. Nelson, the seventh event there. The promotion has also featured 2 visits to the United Arab Emirates. The first was in 2010 for UFC 112 and the second in 2014 for UFC Fight Night: Nogueira vs. Nelson. The promotion has also visited Macau in 3 occasions: China's special administrative region was first visited in 2012 with UFC on Fuel TV: Franklin vs. Le and last visited in 2014 for UFC Fight Night: Bisping vs. Le. The promotion has also visited Singapore with UFC Fight Night: Saffiedine vs. Lim in 2014. The Philippines was the most recent Asian country that the UFC has visited, with UFC Fight Night: Edgar vs. Faber in 2015.

The Ultimate Fighter has had international editions as well: Brazil (since 2012), Australia (vs. United Kingdom – 2012), China (2013), Canada (vs. Australia – 2014), and Latin America (2014).

TRT ban

On February 27, 2014, the Nevada State Athletic Commission banned the use of Testosterone Replacement Therapy (TRT). The UFC followed suit and banned the use of TRT for any of their events, including international markets where the UFC oversees regulatory efforts.

Lawsuits over contractual treatment of fighters

Class action: Le vs Zuffa (UFC) anti-trust lawsuit

In December 2014, an antitrust lawsuit was filed against Zuffa by several fighters, claiming the organization restricts control over fighters' careers and earning potential. The case moved to Nevada federal court, where Zuffa was denied its motion to stay discovery for 15 years of its financial records.

This caused an ongoing debate and struggle over how UFC sensitive information should be handled, and who may view it. Especially concerning MMAFA founder, Rob Maysey who has taken the lead in representing the former athletes and has stated he hopes to achieve reforms similar to the Ali Act (2000).

Later that year, a 12–16 month investigation began that was expected to last until sometime between September 2016 to January 2017. Thus far, both sides have provided over 100,000 documents.

It is estimated that the UFC shares between 16% and 22% of its revenue with fighters, which is vastly lower than sports leagues such as the NBA, MLB, and NHL, which share approximately half of the revenue with their athletes.

There have been several ongoing lawsuits over the contractual treatment of UFC fighters. One of the most recent cases was filed in 2020 by a group of fighters led by Cung Le and Nate Quarry. They alleged that the UFC violated antitrust laws by engaging in anti-competitive practices that kept fighter pay artificially low. The plaintiffs argued that the UFC's practice of using long-term exclusive contracts and "champion's clauses" (which extend a fighter's contract automatically if they win a title) was intended to suppress fighter pay and prevent them from negotiating with other promotions. They also claimed that the UFC engaged in various other anti-competitive practices, such as blocking fighters from using their own image and likeness rights and taking a significant portion of revenue from merchandise sales. The case was initially dismissed by a judge in 2020, but the fighters appealed the decision and in 2021 the appeals court revived the lawsuit and sent it back to the lower court for further proceedings. On October 1, 2023, Zuffa's appeal to the Ninth Circuit court in its antitrust lawsuit has been denied.

Smith vs. UFC

Other lawsuits have also been filed against the UFC, including one by former fighter Leslie Smith, who claimed that the UFC violated federal labor laws by classifying fighters as independent contractors instead of employees. The case was dismissed in 2019, but Smith has appealed the decision.

Class action granted

On August 9, 2023, U.S. District Judge Richard Boulware granted class action status to more than 1,200 former UFC fighters who competed between December 2010 and June 2017 and are suing for $800 million upward to $1.6 billion in wages, as the lawsuit claims Zuffa had abused its power to suppress UFC fighters' wages. The anti-trust law also permits private plaintiffs to be able to recover three times the damages suffered, meaning the UFC may ultimately pay several billions of dollars worth of damages. The case has a scheduled April 8, 2024 trial date.

2016 sale to WME-IMG and a new era

In May 2016, ESPN originally reported that the UFC's parent company Zuffa, LLC was in talks to sell the company for $3.5 billion to $4 billion. In 2015, the UFC had a reported EBITDA of $200–250 million. No official comment was made from the UFC or Dana White regarding the sale. Companies initially interested in the sale were Dalian Wanda Group, China Media Capital, and WME–IMG (Endeavor).

On July 9, 2016, it was officially announced that the UFC would be sold to a group led by WME–IMG, its owner Silver Lake Partners, Kohlberg Kravis Roberts, and MSD Capital, for $4.025 billion. At the time, it marked the largest-ever acquisition in sports. Flash Entertainment (owned by the government of Abu Dhabi) retained its 10% minority stake in the company. White, who owned 9% of the UFC, stayed, having been given a stake in the new business. White remained president. Fertitta stepped down as chairman and CEO. WME–IMG was renamed Endeavor in September 2017. Three years into the Endeavor era, White revealed that an undisclosed company bid $5 billion but Fertittas chose WME–IMG due to a connection they already made with its CEO Ari Emanuel.

In October 2016, MMAJunkie obtained a UFC financial report released by Endeavor, detailing that the promotion had reached a year-to-year high of $609 million in revenue during 2015. 76% of the total was credited to "content" revenue, covering media rights, PPV buys and UFC Fight Pass subscriptions; in turn, 42% of content revenue was credited to pay-per-view buys, followed by U.S. and international media rights.

ESPN partnership

In May 2018, UFC reached new U.S. media rights deals with Disney Direct-to-Consumer and International and ESPN Inc., succeeding those with 21st Century Fox, which began in January 2019. The five-year contracts are cumulatively valued at $300 million per-year for digital and linear rights, roughly doubling the amount paid by Fox in the final year of its previous contract, and include 42 events on ESPN platforms per-year. ESPN linear networks will televise preliminary cards for UFC PPV events, and 10 UFC on ESPN Fight Night events per-year. The subscription streaming service ESPN+ will broadcast 20 exclusive events per-year under the branding UFC on ESPN+ Fight Night; regardless of network, all Fight Night events will feature a full, 12-fight card, and their preliminaries will air exclusively on ESPN+. The ESPN+ service will also hold on-demand rights to UFC library and archive content, new seasons of Dana White's Contender Series, and other new original content. UFC Fight Pass will be purchasable as an add-on for ESPN+ to stream pay-per-view events.

On March 18, 2019, it was announced that ESPN had reached a two-year extension of the contract. In addition, it was announced that in the United States, future UFC PPVs will only be sold through ESPN+ to its subscribers, and will no longer be sold via traditional television providers beginning with UFC 236. At the same time, the standard price for UFC PPVs was lowered to $59.99 (from $64.99), and new subscribers will be able to purchase a bundle of UFC PPV for a year of ESPN+ too.

M-1 Global partnership

On July 18, 2018, it was announced that UFC had entered into a partnership with Russian MMA promoter M-1 Global. M-1 Global will serve as a farm league to scout Russian fighters for UFC and will participate in organizing UFC events in Russia. The deal also gave M-1 champions the opportunity to sign with UFC.

Impact of the COVID-19 pandemic

Due to the COVID-19 pandemic, the UFC went on with its March 13, 2020 event, UFC Fight Night: Lee vs. Oliveira in Brasília, Brazil, behind closed doors. On March 16, the organization announced that the next three events, UFC Fight Night: Woodley vs. Edwards, UFC on ESPN: Ngannou vs. Rozenstruik, and UFC Fight Night: Overeem vs. Harris, would be postponed to future dates.

In regards to its next pay-per-view, UFC 249 on April 18, UFC president Dana White stated that the event would likely go on, but at a new venue behind closed doors. It was originally to be held at Barclays Center, but a stay-at-home order was issued by the New York state government. On March 18, the New York State Athletic Commission also withdrew its sanctioning for the event. Due to international travel restrictions and other withdrawals, a revised card for UFC 249 was unveiled on April 6 with a location still TBD. The next day, White disclosed that he had booked an unspecified venue for two months, in order to host both UFC 249 and other future events involving U.S. fighters. He also disclosed plans to secure a private island, known as "Fight Island", to host events with international fighters.

The new UFC 249 venue was subsequently revealed to be Tachi Palace—a tribal casino in Lemoore, California; as it is on tribal land, it also fell outside of the jurisdiction of the California State Athletic Commission, meaning that events held there could be self-sanctioned. On April 9, the UFC announced that UFC 249 had been cancelled, and all other UFC events would be suspended until further notice. White cited interventions from high-ranking staff of the UFC's U.S. media rightsholders, ESPN Inc. and parent The Walt Disney Company, as well as Governor Newsom. The New York Post reported that Governor of California Gavin Newsom had contacted Disney chairman and former CEO Bob Iger, urging ESPN and the UFC to not hold the event.

Following the decree that professional sports were deemed as "essential services" in Florida, UFC 249 took place on May 9, 2020, at VyStar Veterans Memorial Arena in Jacksonville, Florida with no fans in attendance. Precautionary health and safety measures proposed by the UFC satisfied the Florida State Boxing Commission, which regulates MMA in the state. UFC Fight Night: Smith vs. Teixeira and UFC on ESPN: Overeem vs. Harris were scheduled to take place at the same venue on May 13 and 16, respectively. On Friday, May 8, the UFC announced middleweight fighter Ronaldo Souza was removed from his bout with Uriah Hall at UFC 249 and quarantined after he tested positive for COVID-19, along with his cornermen, despite following the protocols enforced by the UFC. No other athletes or staff tested positive for the disease.

In April 2021, amid the COVID-19 pandemic, the UFC held its UFC 261 event, again at the VyStar Arena in Jacksonville, but with a 100-% sold-out capacity, where attendees were not required to wear masks. Public health experts criticized the event, citing the risks to attendees, as well as to the wider community.

Controversy over eye pokes

In March 2021, there was strong pressure on the UFC to use new fighter gloves after a severe eye poke ended the final bout at UFC Fight Night: Edwards vs. Muhammad. The official UFC gloves are constructed in a way that leaves the fighters fingers extended forward, whereas there are alternative gloves, which the UFC has not used, which are curved at the knuckle and keep a fighter's fingers tucked down. Fighters, trainers and commentators called for new gloves, citing the harms posed to fighters from the standard UFC gloves.

Zuffa buyout by Endeavor

On April 29, 2021, Endeavor successfully launched an initial public offering (IPO) and became a publicly traded company listed on the New York Stock Exchange. Endeavor subsequently used some of the proceeds from the IPO to buy out Zuffa's other shareholders at a value of $1.7 billion, making Zuffa a wholly-owned subsidiary of Endeavor.

Betting scandal

On November 5, 2022, controversy arose when the call for a sports betting fraud investigation was made on a fight involving Darrick Minner a student of James Krause, who is a UFC coach and avid bettor, and Shayilan Nuerdanbieke at UFC Fight Night: Rodriguez vs. Lemos. The UFC was informed by sources that suspicious betting patterns had been observed on the fight. Minner became a large betting underdog just hours before the fight, and the cause of the suspicion came when Minner threw a kick with an apparently injured leg, then kicked with it again after showing signs of injury before being finished by technical knockout shortly thereafter.

On November 6, the UFC released a statement that its official betting partner would look into the matter, but that none of the fighters, coaches, or officials related to the fight were suspected of any wrongdoing. On November 18, the Nevada State Athletic Commission informed the UFC and Krause that Krause's license was suspended and would remain so during the course of the investigation. The UFC then announced that any fighter who chose to continue to be coached by Krause or who continued to train in his gym, would not be permitted to participate in UFC events pending the outcome of the aforementioned government investigations.

Following the controversy, UFC introduced rules that banned athletes, coaches, and their close family from betting on UFC events.

Endeavor and WWE merger to form TKO

On September 12, 2023, Endeavor merged with professional wrestling promotion WWE to form a new publicly traded company under the stock symbol "TKO", which will be overseen by Endeavor's CEO Ari Emanuel. WWE's shareholders will hold a 49% stake in the new company, with Vince McMahon had served as an executive chairman who resigned on January 26, 2024, after Janel Grant, a former WWE employee, filed a lawsuit against McMahon for sex trafficking and sexual assault; the merger agreement valued UFC at $12.1 billion.[] White serves as the CEO for UFC, though his role remains the same as during the Endeavor period.
