Americans will legally wager $3.3 billion on the NCAA men’s and women’s basketball tournaments this year, the American Gaming Association said.

Betting on the tournament is expected to show an increase of 54% over the past three years, the trade group for casinos and sportsbooks said Friday, reflecting the growing number of states that have legalized such wagers.
