UFC 329 sets simultaneous-viewers record despite falling short of White House card total

UFC 329 attracted 15.9 million total viewers across the United States and Latin America, according to figures released by Paramount, while setting a new promotion record of 8.3 million people watching simultaneously at any single moment during the card.

The U.S. accounted for 14.3 million of that combined total, with Latin America contributing the remaining 1.6 million. The event averaged 6.5 million viewers across its runtime. Neither figure matched the UFC White House card from June 14, which drew 17 million total viewers and an average audience of 8.2 million — a number the UFC has since revised upward from an earlier submission of seven million, with the original broadcast delayed by a weather hold.

Where UFC 329 did outperform its predecessor was in peak concurrency. The 8.3 million simultaneous viewers surpassed the previous promotion record of 7.9 million, set when Justin Gaethje defeated Ilia Topuria. For context, Super Bowl LVIII between the Kansas City Chiefs and the San Francisco 49ers in February 2024 reached 11.5 million simultaneous viewers on the same platform — still the all-time Paramount high-water mark.

The card itself ended dramatically. Max Holloway defeated Conor McGregor via injury TKO at the 69-second mark of the first round after McGregor opened with a flying kick and appeared to injure his right knee, leaving him unable to continue. Holloway called for a rubber match in his post-fight remarks, citing financial motivation. The event also set a new gate record for the T-Mobile Arena in Las Vegas, surpassing all previous shows at the venue without any expansion of seating capacity.
