Sean Strickland holds the highest implied probability at 55.4% to remain UFC middleweight champion through the end of 2026 after capturing the belt via split decision over Khamzat Chimaev at UFC 328 in May, marking his second title reign and demonstrating consistent decision-winning form against top competition. Chimaev (18.0%) and Nassourdine Imavov (19.6%) follow as the primary threats due to their recent activity levels, striking volume, and grappling credentials in the division, while Dricus Du Plessis (11.8%) sits lower following his earlier title loss. Trader consensus reflects Strickland’s proven ability to control fights over five rounds and the competitive nature of the 185-pound division, where recent title changes and contender depth create uncertainty beyond the immediate term.
