Michigan, Arizona, and Duke lead Polymarket's 2026 NCAA Tournament winner odds with probabilities clustered tightly around 16-20%, driven by their elite 2025 recruiting hauls featuring five-star talents like Michigan's Danny Hurley targets, Arizona's top-3 class under Tommy Lloyd, and Duke's Cooper Flagg-led juggernaut. Dusty May's arrival at Michigan from FAU injects proven mid-major success into a Big Ten power, while the transfer portal bolsters depth across these programs. Trader consensus highlights parity from NIL-fueled roster flux, one-and-done freshmen volatility, and two full seasons of injury risks, keeping blue-bloods like Kansas and Kentucky trailing despite pedigree, as recent March Madness upsets underscore the tournament's unpredictability.
