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 in June 2026 with a fourth-round corner stoppage of Ilia Topuria at UFC Freedom 250, following his interim title win over Paddy Pimblett earlier that year. At 37, Gaethje has signaled he is unlikely to compete again in 2026 amid mandatory rest, medical clearances, and the cumulative toll of his high-output style. This leaves the division without an immediate title challenger, with top contenders including Arman Tsarukyan, Charles Oliveira, and Topuria positioned for potential 2027 opportunities. Current rankings and recent form reinforce Gaethje's hold through year-end, reflecting the absence of scheduled defenses or division-shifting developments in the interim.
