The Professional and Amateur Sports Protection Act of 1992 (PASPA or Bradley Act) defined the legality of sports betting and was effectively a federal ban, carving out exceptions for only a few states. In 2018, the Act was overturned by the Supreme Court in Murphy v. National Collegiate Athletic Association.1 Since then, sports betting has been legalized in 38 states and the District of Columbia. Online sportsbooks have made it easier for gamblers to make a variety of bets from moneyline bets, which require choosing the winner of a game, to proposition bets ("prop" bets), that often have nothing to do with the final score. According to the Census Bureau, sports betting is now the fastest-growing source of state tax revenue.2
