The American Gaming Association (AGA) estimates that Americans will legally wager $3.1 billion on the men’s and women’s college basketball tournaments this year, up from $2.7 billion in 2024.

This growth underscores the expanding legal sports betting market and the growing trust in legal wagering options. 

“March Madness is one of the most exciting times in American sports, with fans fired up for both the men’s and women’s NCAA tournaments,” said AGA SVP of Strategic Communications Joe Maloney. “As legal wagering expands across the U.S., more fans than ever have the opportunity to bet legally and responsibly.” 

“‘Keep Your Cool,’ our newest ‘Have A Game Plan’ principle, is all about keeping betting fun and respecting the game – no matter how unpredictable March Madness becomes,” Maloney added. 

Since the U.S. Supreme Court’s decision to overturn PASPA in 2018, legal sports betting has expanded to 38 states and Washington, D.C., offering consumers safe and regulated options to engage with their favorite sports. Americans’ support for legal sports betting continues to grow. According to the AGA’s 2024 American Attitudes Survey, 75% of Americans support legal sports wagering in their home state, and 90% view sports betting as an acceptable form of entertainment.
