Multiple divisions remain highly active in 2026, with several belts changing hands or facing unification bouts amid strong contender performances. Justin Gaethje’s upset victories, including a TKO of Ilia Topuria after claiming interim lightweight gold, have reshaped that division’s outlook. Flyweight champion Joshua Van has secured key defenses, while heavyweight unification between Tom Aspinall and Ciryl Gane looms as a pivotal event. Middleweight saw Sean Strickland reclaim the title against Khamzat Chimaev, and bantamweight, featherweight, and light heavyweight continue to feature tight matchups. Recent form, injury recoveries, and scheduled title shots in the second half of the year will determine which fighters secure or retain championship status before year-end.
