When March Madness begins on March 14, 2023, it’s a sure bet that millions of Americans will be making wagers on the annual college basketball tournament.
The American Gaming Association estimates that in 2022, 45 million people — or more than 17% of American adults — planned to wager $3.1 billion on the NCAA tournament. That makes it one of the nation’s most popular sports betting events, alongside contests such as the Kentucky Derby and the Super Bowl. By at least one estimate, March Madness is the most popular betting target of all.
