**UFC 331 is scheduled for September 19, 2026, at Crypto.com Arena in Los Angeles, headlined by flyweight champion Joshua Van defending against Alexandre Pantoja, with Arman Tsarukyan facing Mauricio Ruffy in the co-main event.** Trader consensus heavily favors “No” at 96% implied probability because the event sits on the West Coast, far from President Trump’s typical East Coast bases and amid a packed fall presidential schedule. Trump has attended multiple UFC cards in recent years—including UFC 327 in Miami and the June 2026 White House lawn event tied to his close relationship with UFC president Dana White—but those appearances aligned with more convenient locations or high-profile tie-ins. No official lineup announcements, Dana White comments, or credible reports have signaled travel plans for this Los Angeles card as of early September 2026. Realistic scenarios that could still shift the outcome include a sudden schedule adjustment allowing a short West Coast trip, a major card development that draws heightened attention, or verified last-minute confirmation through official channels or ringside reporting. Market resolution hinges on confirmed physical attendance during any portion of the event via credible sources.
