Betting on March Madness Projected to Reach $4 Billion in 2026
Sports betting on the annual March Madness college basketball tournaments is expected to reach new heights in 2026, with analysts projecting record wagering volumes across the United States. According to industry estimates, regulated sportsbooks could process close to $4 billion in bét during this year’s men’s and women’s tournaments.
Expanding U.S. Betting Markets Driving Growth
Analysts estimate the projected $4 billion betting handle would represent roughly a 6.7% increase compared with the 3.7 billion wagered during the 2025 tournament.
Much of that growth is attributed to the steady expansion of regulated sports betting since the 2018 Supreme Court decision that allowed states to legalize wagering. As more jurisdictions roll out sportsbooks, the number of bettors participating in major events like March Madness continues to rise.
One factor expected to contribute to the increase this year is the addition of new markets such as Missouri, where legal sports betting launched in December 2025. The arrival of new betting platforms in the state could bring thousands of additional participants into the market during the tournament.
Unlike single-game spectacles such as the Super Bowl, March Madness offers dozens of games over multiple weeks, creating more opportunities for bettors to place wagers. This extended format helps generate a cumulative betting volume that rivals or surpasses other sporting events in total handle.
A Three-Week Betting Marathon
The 2026 edition of the tournament begins with early games around March 17, launching what analysts often describe as one of the busiest betting periods of the year for sportsbooks.
During the tournament, fans can wager on a wide range of markets, from game winners and point spreads to prop bets tied to individual performances and tournament outcomes. The sheer number of matchups across both the men’s and women’s brackets encourages repeat betting as teams advance through successive rounds.
Industry analysts estimate that sportsbooks could generate around $279 million in operator revenue from the projected $4 billion handle, depending on final outcomes and hold percentages. While the tournament’s betting volume is spread across many games, its cumulative scale makes it one of the most lucrative events in the annual sports betting calendar.
The 2026 March Madness offers a wide range of wagering options, increasing the total betting handle.
Prediction Market Could Add Hundreds of Millions More
Beyond traditional sportsbooks, analysts note that emerging prediction markets may also play a role in overall betting activity related to the tournament.
Estimates suggest that prediction-market platforms could generate the equivalent of roughly $530 million in additional handle-like activity tied to March Madness outcomes. If included alongside sportsbook wagers, the broader wagering ecosystem connected to the tournament could approach $4.5 billion in total activity.
However, experts caution that prediction market trading differs from traditional sports betting, making direct comparisons between the two categories difficult. Still, rapid growth of both regulated sportsbooks and alternative betting platforms underscores the cultural and economic impact of March Madness in the United States.
As the tournament tips off, operators and analysts alike will be watching closely to see whether the anticipated surge in wagering translates into another record-setting year for one of the most bet-on sporting events in the country.
