March Madness creates more betting volume in three weeks than most sports generate in a year — here's which sportsbook gives you the best edge for the tournament.
The NCAA Tournament is the best three weeks in sports betting. Lines on mid-major teams are often set by smaller markets and can be exploited before sharp money arrives. Same-game parlays on tournament games attract massive promotional boosts. And for casual bettors, the bracket-style elimination format makes every game feel critical. Here's how to maximize value in 2026.
Best for Early Round Upset Value: DraftKings and Bet365
First-round games featuring 12-vs-5 and 11-vs-6 matchups are historically underpriced for underdogs. DraftKings and Bet365 offer the most comprehensive alternate line markets for these games, letting you grab the underdog at a custom spread rather than a large moneyline number.
Best for March Madness Same-Game Parlays: FanDuel
FanDuel SGP+ is at its best during March Madness, with daily boosts and featured combinations on every major tournament game. During the first weekend, FanDuel frequently offers SGP odds boosts that improve already-good prices by 25-50%.
Best for Tournament Futures: Caesars and BetMGM
Championship futures can be locked in before the tournament or during it as teams advance. Caesars and BetMGM both offer live tournament futures updating through each round. Backing a 5-seed that won its first two games at +600 to win the tournament can offer exceptional value relative to their actual probability.
