Sean Strickland is the heaviest-backed contender to hold the UFC Middleweight championship on 31 December 2026, with Nassourdine Imavov and Khamzat Chimaev forming a close cluster behind him. The market spans 19 named outcomes but volume is concentrated heavily on three fighters. Resolution is determined by the official UFC Middleweight champion at 12:00 PM ET on 31 December 2026, using UFC.com as the primary source.

Market structure

Nineteen outcomes are listed, but trading is heavily concentrated on three fighters: Sean Strickland leads, with Nassourdine Imavov and Khamzat Chimaev close behind. All remaining contenders attract minimal volume. Resolution requires an undisputed, official UFC Middleweight champion — interim title holders do not qualify. If the belt is vacant at the resolution moment, the market resolves to 'Other'. The definitive source of truth is the official UFC athlete roster at ufc.com.

Background

The UFC Middleweight division has seen rapid turnover at the top since 2023. Dricus Du Plessis won the undisputed belt before losing it, and the division has cycled through multiple champions in a short period — including Israel Adesanya and Sean Strickland — producing an unusually volatile title picture. Strickland, a former champion known for his high-volume striking and durable chin, remains a prominent figure in contention. Nassourdine Imavov has risen sharply through the rankings on the back of a strong winning streak, while Khamzat Chimaev's combination of wrestling and striking has long made him a divisional threat. The question of who holds the belt on the final day of 2026 depends on scheduled and unscheduled title fights over the coming months.

Key factors

Several structural factors shape how this market could move. The UFC's event scheduling determines when title fights occur, and a late-2026 card could directly influence the resolution date's champion. Any fighter currently holding the belt is vulnerable to a scheduled defence, which could change the landscape entirely. Injury, suspension, or weight-cutting complications could force title fight cancellations or replacements. Khamzat Chimaev's path to a title shot has historically been disrupted by health and matchmaking complications, making his timeline uncertain. Imavov's recent form has elevated him into title contention, but a single loss before a title opportunity would reset his candidacy. Strickland's previous title reign demonstrated his ability to win at the highest level, but his record in rematches introduces variance. The 'Other' outcome — triggered if the belt is vacant at the resolution moment — represents a genuine contingency in a division with a recent history of stripped or relinquished titles.
