Sean Strickland holds the strongest position among middleweight contenders to finish 2026 as champion, following his split-decision victory over Khamzat Chimaev at UFC 328 in May that reclaimed the title for a second reign. Traders assign him the highest implied probability based on this momentum, his proven durability against elite wrestlers, and an anticipated defense against Nassourdine Imavov later in the year. Chimaev’s first career loss drops his standing despite prior dominance, while Dricus du Plessis remains a factor as a former champion but sits further back after losing the belt. The division’s rapid turnover and upcoming matchups continue to shape long-term probabilities through the remainder of the calendar.
