TKO Group, a publicly owned company operating under Endeavor and headquartered in the US, was founded in 2023. With approximately 180 employees, it reported $4.7B in revenue as of 2025. The company functions as an entertainment provider, comprising UFC, a mixed martial arts organization, and WWE. TKO Group was created by Endeavor Group Holdings as part of a merger between World Wrestling Entertainment (WWE) and Zuffa, the parent company of the Ultimate Fighting Championship (UFC).
On June 26, 2026, TKO Group announced its recent UFC event, "Freedom 250," hosted on the South Lawn of the White House, was its most-watched UFC event ever in the U.S., attracting an estimated 34 million global viewers. This figure doubled the previously reported 17 million viewers from the U.S. and Latin America, positioning it among the most-watched events in Ultimate Fighting Championship history. Earlier on the same day, TKO Group Holdings reported Q1 2026 revenue of US$1.6 billion and an adjusted EPS of US$1.12, both exceeding Wall Street estimates and contributing to improved investor sentiment. Previously, on June 22, UFC sponsor Polymarket, a crypto-based prediction market, faced scrutiny after a Wall Street Journal investigation alleged it ran a marketing campaign involving fake bets, dummy websites, and undisclosed paid promotions targeting American users, despite being banned from operating in the U.S. since 2022. This followed WWE's announcement on June 19 of several new additions and an unprecedented twist to the final card for its 2026 Night of Champions event.
