Multiple divisions saw title changes in the first half of 2026, including Carlos Ulberg claiming the light heavyweight belt via first-round knockout in April, Sean Strickland capturing the middleweight title in May, and Justin Gaethje securing the lightweight strap with a fourth-round stoppage in June. These outcomes, alongside Tom Aspinall's undisputed heavyweight status and ongoing interim situations, reflect active title turnover driven by recent form, stylistic matchups, and injury recoveries. Remaining weight classes feature established champions like Alexander Volkanovski and Petr Yan facing defenses or contenders, while upcoming cards through year-end will shape additional crowning opportunities based on official injury reports, ranking climbs, and fight announcements.
