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’s recent capture of the undisputed UFC lightweight title via fourth-round TKO over previously undefeated Ilia Topuria at UFC Freedom 250 in June 2026 positions him as the overwhelming market leader for end-of-year champion. The 37-year-old veteran, now on a three-fight win streak after earlier interim title successes, has publicly indicated he is unlikely to compete again in 2026 and will delay his first defense until 2027. This extended inactivity, combined with Topuria’s recovery from a broken orbital and the division’s crowded contender picture featuring Arman Tsarukyan, Charles Oliveira, and others still sorting out rankings through upcoming bouts, reinforces trader consensus around Gaethje holding the belt through December. While long-shot outcomes remain possible if unforeseen injuries or rapid title challenges materialize, Gaethje’s current standing and schedule create the clearest path to retaining championship status at year-end.
