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 "Rampage" 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.
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 its 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.
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."
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.
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 its 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.
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 2024 with UFC Fight Night 246. UFC's second 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 18 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. The UK's most recent event was in Manchester, England with UFC 304 in 2024. Ireland has held UFC 93 in 2009 and UFC Fight Night: McGregor vs. Brandao 5 years later. In continental Europe, Germany has hosted 6 times, the first being UFC 99 in 2009, UFC 122 in 2010, UFC Fight Night: Munoz vs. Mousasi in 2014, UFC Fight Night: Jędrzejczyk vs. Penne in 2015, UFC Fight Night: Arlovski vs. Barnett in 2016, and most recently, UFC Fight Night: Shogun vs. Smith in 2018.

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. Its 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. its last visit was in 2014 for UFC Fight Night: Hunt vs. Nelson, the seventh event there. The promotion has also featured 3 visits to the United Arab Emirates. The first was in 2010 for UFC 112 the second in 2014 for UFC Fight Night: Nogueira vs. Nelson and the third in 2024 for UFC on ABC: Sandhagen vs. Nurmagomedov.

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 its events, including international markets where the UFC oversees regulatory efforts.
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.
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. On March 20, 2024, TKO, UFC parent company reached an agreement to settle all claims in the class action lawsuits for $335 million where the settlement amount will be deductible for tax purposes. However, on July 31, 2024, Judge Richard Boulware ruled that the case would be heard by a jury and denied the preliminary approval for a settlement and reset a tentative date for trial of October 28.
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.
