Justin Gaethje claimed the interim lightweight title with a unanimous decision win over Paddy Pimblett in the UFC 324 main event, vaulting to #1 in the lightweight rankings. Ilia Topuria, the undisputed lightweight champion, now has Gaethje positioned as his next challenger upon return. This sets up a high-stakes unification bout in a stacked division. The update marks the first official rankings change of 2026 following the year's opening event. Expect Gaethje vs. Topuria to headline a major card later this year.
Because this story carries an unconfirmed status, everything that follows should be treated as a report that has not been officially verified.

Justin Gaethje is reported to have captured the interim lightweight title at UFC 324, defeating Paddy Pimblett by unanimous decision in the main event and ascending to the number-one position in the lightweight rankings. The result, if confirmed, would set up a unification fight between Gaethje and undisputed champion Ilia Topuria upon Topuria's return.
Gaethje, 37, now carries a reported record of 28-5-0 and holds interim champion status in the lightweight division. The American fighter, who trains out of Genesis Training Center, brings a relentless striking output to the cage, landing 6.48 significant strikes per minute at 58 percent accuracy — figures that rank among the most dangerous in the division. Standing five-foot-eleven with a 70-inch reach, "The Highlight" has built his reputation on forward pressure and clean, heavy punching.

Pimblett, 31, falls to 23-4-0 following the reported defeat. The Liverpool native, who competes out of Next Generation MMA, had entered the contest ranked sixth at lightweight and had shown strong output of his own, averaging 5.49 significant strikes per minute at 52 percent accuracy. His 73-inch reach gave him a length advantage, but the decision loss drops him from his previous ranking position.
Topuria, the undisputed lightweight champion, holds a 17-1-0 record and sits atop the pound-for-pound rankings at just 29 years old. The Spain-based Georgian southpaw lands 4.81 significant strikes per minute while also mixing in nearly two takedown attempts per 15 minutes, making him a multi-dimensional threat across any potential unification matchup.

Why it matters
- A Gaethje-Topuria unification would bring together the division's two most striking-heavy competitors
- Topuria's pound-for-pound number-one status makes the bout one of the most significant possible in the sport
- The lightweight division, already stacked, would have its undisputed title picture clarified by this matchup
- This would mark Gaethje's first championship reign if the interim status is officially confirmed
