BracketProof 2027 March Madness Model
Our 2027 NCAA Tournament bracket publishes on Selection Sunday, March 14, 2027. The same model that called 9 of 13 national champions across a 13-year leave-one-out backtest, averaging 1274 ESPN points, will generate the 2027 picks.
What to expect
A full 63-game bracket with every pick justified by the model, a champion confidence reading, and game-by-game odds. The 2027 engine inherits the architecture that scored 830 ESPN points in 2026 (Michigan champion call) and averaged 1274 over the full backtest window.
The core model is a gradient-boosted champion classifier combined with a secondary ensemble for non-championship games, matchup-specific routing, and a market-consensus cross-check. Features are drawn from KenPom efficiency metrics and updated through Selection Sunday.
