UFC 329 draws nearly 16 million viewers for the return of Conor McGregor

UFC 329 drew 15.9 million total viewers across the U.S. and Latin America, according to Nielsen and Adobe Analytics data released Thursday by Paramount+. While the viewership fell just short of last month's UFC White House event, which reached 17 million viewers in the same markets, the card still represents a major success for the promotion and Conor McGregor's highly anticipated return after a five-year absence from competition.

The event averaged 6.5 million concurrent viewers—notably below UFC White House's 8.2 million average—but UFC 329 edged ahead in one critical metric. The card peaked at 8.3 million concurrent streams, surpassing UFC White House's 7.9 million peak and establishing UFC 329 as the second-largest live event in Paramount+ history for concurrent viewership, behind only Super Bowl LVIII's 11.5 million.

Context matters for these numbers. The McGregor-Max Holloway rematch, which served as the main event, lasted only 69 seconds before McGregor suffered an apparent knee injury on his opening flying kick and was forced to withdraw. Additionally, UFC 329 competed for viewers against a World Cup quarterfinal between Argentina and Switzerland, which may have fractured the overall audience. Despite these factors, the viewership demonstrates strong audience interest—the card exceeded historic benchmarks like the first-ever UFC broadcast on FOX in 2011, which averaged 5.7 million viewers and peaked at 8.8 million, showing the enduring appeal of major UFC moments.
