UFC 331 is scheduled for September 19, 2026, at the Crypto.com Arena in Los Angeles, with live streaming available on Paramount+. The event’s headline bout is a flyweight title rematch where reigning champion Joshua Van will defend his belt against Alexandre Pantoja. Their first encounter at UFC 323 ended swiftly due to an injury to Pantoja, who was then stripped of the title after four successful defenses. This time around, betting odds have shifted, favoring Van as the likely winner.

The co-main event features a pivotal lightweight clash between Arman Tsarukyan and Mauricio Ruffy, a five-round fight that could decide the next contender for Justin Gaethje’s 155-pound title. Tsarukyan comes into the fight with a recent submission win, while Ruffy boasts a June TKO victory against Michael Chandler. This bout is highly anticipated given its potential impact on the lightweight division’s future.

The UFC 331 fight card is structured with early prelims starting at 5:30 p.m. ET, followed by prelims at 7:00 p.m. ET, and the main card kicking off at 9:00 p.m. ET. Alongside the headlining matchups, the main card includes notable fights such as Patrício Pitbull versus Choi Doo-ho, Gable Steveson facing Sean Sharaf, and Alonzo Menifield against Iwo Baraniewski. The preliminary card kicks off with fighters like Marlon Vera and Tai Tuivasa, contributing to a packed night of bouts.

Joshua Van carries a strong record of 17-2, with his last title defense occurring in May 2026 via fifth-round TKO against Tatsuro Taira. Pantoja, holding a 30-6 record, was initially the favorite but has now seen his underdog status rise ahead of the rematch. Meanwhile, Tsarukyan opened as a strong favorite against Ruffy, who entered with a respectable underdog position. UFC 331 is shaping up as a key event with significant implications for title landscapes across two divisions.
