This market will resolve according to the team that wins the 2026 NCAA Men’s Basketball Tournament. If it is impossible for a team to win the 2026 NCAA Men’s Basketball Tournament according to the rules of the competition (i.e. they are eliminated) , the corresponding market will immediately resolve to “No”. If for any reason no winner is declared by December 31, 2026, 11:59 PM ET, this market will resolve to "Other". The resolution source for this market will be information from the NCAA.Trader consensus on the 2026 NCAA Tournament winner reflects a wide-open futures market, with Arizona's top 27.1% implied probability driven by its elite No. 4-ranked 2025 recruiting class featuring high-end guards and wings, complemented by key transfer portal additions like versatile forwards. Michigan (20.5%) surges on coach Dusty May's rapid rebuild, landing top-10 commits and a haul of proven scorers from the portal post their strong 2024-25 Big Ten showing. Duke (16.5%) and Illinois (13.5%) keep pace via Cooper Flagg's sophomore leap potential and Brad Underwood's portal dominance, respectively, amid high returning production across the leaders. Recent commitments in the class of 2025 and NIL-fueled transfers over the past month have bunched these probabilities, underscoring balanced paths through conference realignment and bracket uncertainty.
