Michigan edges Arizona and Duke as the slim 2026 NCAA Tournament favorite at 22.5% implied probability on Polymarket, with all three clustered tightly under 23% due to their top-tier 2025 recruiting classes powering roster upgrades via the transfer portal and NIL collectives. Dusty May's Michigan boasts the No. 1 class per 247Sports, featuring five-star guards Naasir Cunningham and Trey McKenney alongside key transfers like FAU's Vladislav Goldin for frontcourt size. Arizona's Tommy Lloyd secured the No. 3 class with versatile wings, while Jon Scheyer's Duke (No. 2 class) returns elite talent like Kon Knueppel. Houston (10.5%) lingers via Kelvin Sampson's perennial defensive prowess and portal reinforcements, highlighting the offseason fluidity where portal departures or early injuries could rapidly reshape this competitive futures landscape.
