(TKO) is a publicly traded sports entertainment company majority owned by Hollywood talent and media conglomerate Endeavor and headquartered in New York City. Formed in 2023 as a merger between World Wrestling Entertainment (WWE) and the Ultimate Fighting Championship (UFC), TKO is one of the world’s largest combat sports companies and a leading promoter of pay-per-view and live events.

　　At its core, TKO aimed to monetize and elevate mixed martial arts (MMA) and theatrical wrestling—both formerly niche combat sports—into mainstream spectacle events capable of global growth. In doing so, TKO was able to diversify its core business into several segments and brands, each offering its own products and services.

　　Business segmentsTKO reports its revenue under three main segments, each built around distinct brands and offerings.

　　UFC: Mixed martial arts promotion, pay-per-view events, digital streaming subscriptions, Performance Institutes (official training facilities), and UFC Gyms (franchises).WWE: Weekly wrestling programming (Raw, Smackdown), premium live events, and various consumer products.IMG: Sports representation, event management, licensing, and media rights/production. On Location—TKO’s premium live-event hospitality business—is reported within the IMG segment. Together, these brands make up TKO’s core reporting structure. Professional Bull Riders (PBR) is part of TKO’s portfolio but, as of 2025, it sits outside the three segments.

　　1953–1982: Roots and the regional era of wrestlingTKO’s roots trace back to 1953, when the Capitol Wrestling Corporation (CWC), founded by Vincent J. McMahon, staged its first show. The McMahon family’s involvement went back further: Vincent’s father, Jess McMahon, had promoted boxing and wrestling in the early 20th century and is regarded as the dynasty’s patriarch. Jess died in 1954, a year after CWC’s founding.

　　In 1963, the company was rebranded as the World Wide Wrestling Federation (WWWF). It shortened its name to the World Wrestling Federation (WWF) in 1979. In 1982, Vince McMahon (Vincent K. McMahon), son of Vincent J. McMahon, purchased the WWF from his father through Titan Sports, Inc., a company he and his wife Linda McMahon had incorporated in 1980. This transaction marked the true beginning of WWE’s modern era.

　　1983–1994: National expansion and pay-per-viewThe McMahons’ 1982 purchase of WWF marked a significant turning point for the company. Under their leadership, WWF became an entertainment powerhouse and a globally recognized brand.

　　In 1985, WWF staged its first pay-per-view event, WrestleMania, establishing a flagship model for monetizing wrestling events at scale. Over time, the event turned wrestlers into mainstream celebrities and made wrestling a fixture of popular culture.

　　In 1993, WWF launched Monday Night Raw—a weekly live wrestling event featuring storylines and largely uncut action, marking a departure from the pretaped broadcasts that had long defined televised wrestling. Not only did Raw revitalize wrestling’s televised distribution; it also anchored WWF’s broadcast dominance.

　　That same year (1993), TV production company Semaphore Entertainment Group and its fledgling Ultimate Fighting Championship (UFC) held its debut pay-per-view event. Although “no-holds-barred” contests date back at least to pankration, introduced at the XXXIII Olympiad in 648 BCE, UFC popularized the modern form of MMA, bringing together fighters of diverse disciplines in a single competition. At a time when boxing dominated combat sports, wrestling leaned heavily on scripted spectacle, and traditional martial arts remained niche, UFC carved out a space of its own—grittier, more varied, and increasingly mainstream.

　　1995–2002: Monday Night War, IPO, and consolidationFrom 1995 to 2001, WWF’s Monday Night Raw and WCW’s Monday Nitro aired head-to-head in what became known as the “Monday Night War.” WCW had emerged after media magnate Ted Turner acquired the National Wrestling Alliance’s flagship promotion in 1988 and rebranded it World Championship Wrestling (WCW), turning it into a national competitor.

　　Hulk Hogan (left, competing as Hollywood Hogan) battling Dwayne (“The Rock”) Johnson at WrestleMania X8, 2002; Johnson won the match.© George Pimentel—WireImage/Getty ImagesWCW struck first by scheduling Nitro directly against Raw and courting viewers with more reality-based storylines aimed at the 18–34 demographic. It also lured away several of WWF’s top stars, including Hulk Hogan, “Macho Man” Randy Savage, Lex Luger, and Kevin Nash. Capitalizing on mainstream buzz, WCW also staged celebrity tie-ins—most notably NBA rivals Dennis Rodman and Karl Malone at Bash at the Beach (1998).

　　WCW’s strategy worked for a stretch: Nitro led the ratings for 83 consecutive weeks (1996–1998). WWF countered with what became known as the “Attitude Era”—a darker, faster-paced presentation built around antihero protagonists and harder-hitting matches, with storylines aimed at older teens and adults. The shift, led by breakout stars such as Dwayne “The Rock” Johnson and “Stone Cold” Steve Austin, pulled viewers back to Raw and flipped the ratings momentum.

　　On October 19, 1999, WWF went public on the Nasdaq under the ticker WWFE, with shares priced at $17 and closing its first day at $26.63. The IPO provided fresh capital as the WWF/WCW rivalry intensified and the company expanded its media footprint.

　　By 2001, WCW’s overall fundamental and financial position had weakened to the point where the WWF was able to swoop in and acquire its biggest competitor. This move not only put an end to the long-standing rivalry, but also consolidated the U.S. wrestling market. The following year, WWF changed its name to World Wrestling Entertainment (WWE) to resolve a brand dispute with the World Wildlife Fund, which had been using the acronym WWF since its founding in 1961.

　　2001–2015: UFC under Zuffa—legitimacy and expansionMeanwhile, UFC was facing increasing regulatory pressures that threatened its pay-per-view model and, as a result, its financial stability. On the verge of bankruptcy, UFC was sold in 2001 to Zuffa, LLC, a company founded by brothers Frank and Lorenzo Fertitta to operate UFC; Dana White, who helped drive the acquisition, became president and a minority owner.

　　UFC CEO Dana White speaking during a press conference in Manchester, England, July 25, 2024.© Mike Roach/Zuffa LLC—UFC/Getty ImagesRestructured under Zuffa, UFC transitioned from a financially struggling combat spectacle into a more regulated and marketable combat sport. Rules were standardized to meet athletic commission requirements, recasting MMA as a sanctioned sport rather than an underground brawl. This stabilized the company’s pay-per-view prospects while opening the door to more mainstream broadcasting deals.

　　UFC then expanded aggressively through acquisitions that consolidated the global MMA landscape. In 2007, UFC acquired Pride Fighting Championships, a Japanese MMA promotion company and, prior to the takeover, UFC’s most formidable overseas competitor. In 2011, UFC purchased American kickboxing promoter Strikeforce, absorbing its fighters and cementing UFC’s position as the most dominant MMA promoter in the U.S.

Ricardo/Shutterstock.com2016–2022: Endeavor era for UFC & big league mediaUFC’s pivotal moment took place in 2016 when WME–IMG (later Endeavor Group Holdings) purchased a controlling interest in the MMA company for $4 billion. Endeavor would go on to buy out all remaining minority stakeholders in 2021, gaining full control over UFC.

　　In addition to this buyout, UFC—under Endeavor’s leadership—secured a multiyear U.S. rights agreement with ESPN in 2018 (effective 2019), with ESPN+ becoming the exclusive U.S. distributor of UFC pay-per-view events. This twin milestone positioned UFC for its future merger with WWE, completing the former’s climb from once-controversial sideshow to mainstream cultural and commercial juggernaut.

　　2023: Formation of TKO Group HoldingsIn 2022, WWE launched a probe into allegations of misconduct by Vince McMahon. Investigators identified nondisclosure agreements with multiple female employees and determined that he had paid the women nearly $20 million. McMahon stepped down as WWE’s chairman and chief executive in June 2022, but returned as executive chairman in January 2023.

　　That same year, Endeavor (parent of UFC) and WWE announced an agreement to merge UFC and WWE under a new public entity, TKO Group Holdings, in a deal valuing the company at about $21 billion. Upon close, Endeavor held 51% and WWE shareholders 49%; TKO began trading in September 2023.

　　Although McMahon initially served as executive chairman of TKO, he resigned in 2024 after a woman accused him of sexual assault and sex trafficking. Federal investigators opened a probe into sexual abuse allegations, which ended in 2025 with no charges filed. Also in 2025, McMahon reached a settlement with the SEC concerning payments to two women; without admitting guilt, he agreed to pay a fine and reimburse WWE.

Alex Bierens de Haan/Getty ImagesThe merger that formed TKO provided scale and diversification—pairing family-friendly scripted entertainment with unscripted MMA—to broaden its appeal to audiences, broadcasters, and advertisers. Negotiating as a unified company increased leverage on media rights and sponsorships and created room for long-term revenue growth and cost efficiencies.

　　2024–2025: Media rights and portfolio expansionTKO experienced a surge in distribution activity and expansion starting in 2024. Netflix (NFLX) secured the rights to WWE Raw for the following year, marking a groundbreaking industry shift from traditional TV broadcasting to streaming. Also in 2025, ESPN secured U.S. media rights to WWE’s premium live events, bringing WWE and UFC shows onto the same ESPN platforms, while Raw continues to air on Netflix.

　　Internationally, UFC made its Saudi Arabia debut in June 2024, part of a broader Middle East strategy. In April 2025, WWE announced it would acquire Mexico’s Lucha Libre AAA, a leading promotion of lucha libre—the country’s masked, high-flying style of professional wrestling. TKO also debuted a Brazilian jiu-jitsu show in June 2025 and staged its first integrated showcase—“TKO Takeover”—in Kansas City (April 24–28, 2025), bundling PBR, UFC, and WWE in one venue.

　　Lucha libre, as performed by the London-based wrestling troupe Lucha Britannia.Hushhushvideo (A Britannica Publishing Partner)On the financial side, TKO declared its first cash dividend in February 2025 and increased the quarterly amount later in the year. On February 28, 2025, TKO completed an all-stock, $3.25 billion acquisition of IMG, On Location, and Professional Bull Riders from Endeavor, issuing new shares to Endeavor and increasing Endeavor’s stake in TKO.

　　Then, on March 24, 2025, Silver Lake—a private equity firm that invests in technology, media, and sports—led the deal to take Endeavor private. Because Endeavor held a majority stake in TKO, Silver Lake, through Endeavor, controlled about 61% of TKO’s voting power, while TKO remained publicly traded.

　　ControversiesLike many high-profile companies, TKO and its predecessors have faced legal and reputational scrutiny. Allegations noted below reflect claims in lawsuits or reporting; settlements typically include no admission of liability.

　　UFC antitrust settlement (2024–25). In 2024, UFC paid $375 million to settle a decade-long antitrust suit brought on by former fighters claiming that the company used its monopoly-like status to suppress wages and lock talent into restrictive contracts.

　　“Ring boy” and renewed lawsuits (1990s; renewed filings 2024–25). Allegations of sexual abuse involving teenage “ring boys” surfaced in the early 1990s and have periodically reappeared in subsequent lawsuits and reporting. The claims have been contested by the defendants—including Vince and Linda McMahon—and outcomes have varied over time; no single comprehensive judgment has resolved all such allegations.

　　Steroid and drug allegations. WWE has faced repeated accusations concerning the distribution of anabolic steroids to its wrestlers. The most notable case culminated in a federal indictment in 1993 against Vince McMahon. Although McMahon was eventually acquitted, the scandal, alongside other controversies, left a lasting stain on WWE’s reputation and raised ongoing questions about the company’s culture and oversight.

　　SEC enforcement. In 2025, the SEC fined Vince McMahon $400,000 for failing to disclose settlement agreements to WWE, which the agency said circumvented internal controls and led to material misstatements in WWE’s 2018 and 2021 financial statements. Without admitting or denying the findings, McMahon agreed to pay a $400,000 civil penalty and reimburse WWE $1.33 million.

　　LegacyFrom its origins in regional wrestling promotions to its present-day position as a multibillion-dollar global sports entertainment group, TKO has helped redefine how combat sport events are presented, distributed, and monetized. By elevating mixed martial arts and scripted professional wrestling—once niche—into mainstream attractions, TKO expanded into adjacent businesses and brands across live events, media rights, licensing, and hospitality. Its legacy is defined chiefly by expansion and media innovation, with controversies remaining a secondary thread in the company’s story.
