This market will resolve according to the official UFC Lightweight division champion on December 31, 2026 at 12:00 PM ET. Only official UFC division champions will count. Interim champions will not count. If the relevant belt is vacant at this market’s check time, or there is otherwise no champion in the specified division, this market will resolve to “Other”. The primary resolution source for this market will be official information from the UFC (https://www.ufc.com/athletes).Justin Gaethje captured the undisputed UFC lightweight title with a fourth-round corner-stoppage TKO over previously unbeaten Ilia Topuria at UFC Freedom 250 in June 2026, following his interim-title win over Paddy Pimblett earlier that year. At 37, Gaethje has indicated he is highly unlikely to compete again in 2026 after two bouts already, leaving limited windows for a defense or challenger emergence before year-end. Arman Tsarukyan rebounded from extended inactivity with a submission victory and sits as the clear top contender, while Topuria must secure a win to reenter title contention. The rest of the division, including Charles Oliveira, Max Holloway, and Mauricio Ruffy, trails in the rankings with no imminent path to strip the belt. Trader consensus therefore centers on Gaethje retaining the championship through the remainder of the year.
