UFC White House: Ilia Topuria vs. Justin Gaethje live stream watch party

The UFC White House—a historic inaugural event held on the South Lawn in Washington, D.C., on Sunday—will feature a stacked card headlined by lightweight champion Ilia Topuria's first title defence against interim champ Justin Gaethje. MMA Fighting is hosting a live-stream watch party starting at 8 p.m. ET / 5 p.m. PT with hosts Mike Heck, Jed Meshew, and special guests.

The co-main event marks former two-division champion Alex Pereira's bid to become the first fighter in UFC history to capture titles across three weight classes, facing interim heavyweight titleholder Ciryl Gane. The card also includes a bantamweight showdown between ex-champ Sean O'Malley and rising contender Aiemann Zahabi, a heavyweight clash between undefeated Josh Hokit and knockout specialist Derrick Lewis, and a lightweight bout between Mauricio Ruffy and Michael Chandler. A middleweight fight pits Bo Nickal against Kyle Daukaus. The event opens with a featherweight contest between Diego Lopes and Steve Garcia.
