Who will be UFC Lightweight champion at the end of 2026?

Traders currently price "Justin Gaethje" at 84% for "Who will be UFC Lightweight champion at the end of 2026?". Full distribution: Justin Gaethje 84%, Ilia Topuria 6%, Charles Oliveira 5%, Arman Tsarukyan 4%. The market has traded $667K in total volume and resolves Dec 31, 2026. Justin Gaethje holds the lightweight title following his 2026 unification victory over Ilia Topuria and subsequent decision win over Paddy Pimblett, positioning him as the clear frontrunner to remain champion through year-end. Trader consensus reflects Gaethje's experience in high-stakes title fights, durable chin, and knockout power, alongside limited immediate defenses scheduled before December. Topuria's move up from featherweight and recent setbacks have cooled his odds, while Oliveira, Tsarukyan, and Pimblett remain active contenders with strong recent form but face stylistic or scheduling hurdles against the current champ. Market pricing accounts for Gaethje's potential rest advantage and the division's depth, where upsets remain possible in any defense.
