Four rounds were enough. At 37, Justin Gaethje stopped Ilia Topuria by TKO (retirement) to win the undisputed UFC lightweight title at UFC Freedom 250 on the South Lawn of the White House on 15 June 2026. Topuria’s corner declined to let him answer the bell for the fifth after sustained facial damage and a late knee to the body. The promotion has not announced dates for Gaethje’s first defence.

At 37, Gaethje finally took undisputed gold after a career of interim belts and headline fights, and he did it by forcing the issue late in a bout that turned increasingly one-sided.

Main event turning points

Ilia Topuria began the fight strongly, carrying his unbeaten record into the match and finding success in the second round with a takedown and focused body work. That early momentum cost Gaethje time, but it didn't last. From Round 3 the momentum shifted: Gaethje opened heavy cuts and swelling on Topuria’s face, and three rounds of accumulated damage left Topuria bloodied and swollen.

Ringside medics and officials were active in the closing stages. A cageside doctor checked Topuria between rounds after the third and again after the fourth, and, after a brutal knee to the body as Round 4 ended, Topuria’s corner declined to let him answer the bell for the fifth. Officials recorded the finish as TKO, listed as a retirement, at 5:00 of Round 4. The ringside doctor had briefly recommended a stoppage after Round 3 before allowing the fight to continue, and the corner finally stepped in before Round 5.

Topuria was taken to hospital after the event. UFC CEO Dana White said Topuria was "busted up" and expected to be out for some time, noting possible orbital damage. For Topuria the defeat was his first professional loss; he had been unbeaten across two divisions prior to the White House fight.

Gaethje’s claim and the card around it

Gaethje spoke about the plan that carried him through the fight, saying, "I can't even believe it. I knew I was going to have to get through the first round. His skills are unmatched when he’s fresh. I knew my durability, my tenacity, my heart will carry me through those first couple of rounds.

And no one can outwork me in round three, especially the championship rounds four and five." The line was part celebration, part explanation for how a veteran fighter closes distance and damage over five rounds.

The main event capped a historic card staged at an unusual venue for the promotion. UFC Freedom 250 on the South Lawn was heavy on stoppages: Ciryl Gane knocked out Alex Pereira to claim the interim heavyweight title, positioning Gane as the clear No. 1 contender for the undisputed heavyweight crown. Sean O’Malley recorded a TKO over Aiemann Zahabi, his first knockout win since 2023.

Other results underlined the night’s finishing tendency. Josh Hokit stopped Derrick Lewis, Mauricio Ruffy beat Michael Chandler by stoppage, Bo Nickal defeated Kyle Daukaus by knockout or TKO, and Diego Lopes stopped Steve Garcia, all recorded as KO or TKO. The sequence of finishes rewrote both divisions in short order: Gaethje reset the lightweight picture with a new champion, and Gane’s interim title creates a single, obvious challenger at heavyweight.

Officials and medical staff were particularly prominent in the closing moments of the main event, and their decisions shaped the result. The combination of sustained facial damage, medical checks between rounds, and a final body strike at the end of Round 4 made the stoppage an accumulation rather than a single dramatic sequence. For Gaethje, the outcome is the long-awaited completion of a career that has included interim titles and repeated runs at championship gold.
