Indiana legalized sports betting following the 2018 Supreme Court decision overturning the federal PASPA ban, with legislation approved in 2019 allowing both mobile and in-person wagering. Since then, the state has seen significant growth in its sports betting market, highlighted by record handles exceeding $500 million monthly and expanding sportsbook operators, including major brands like DraftKings, BetRivers, and ESPN BET. Key moments include the addition of pari-mutuel horse racing wagering, notable large bets on NBA Finals underdogs like the Indiana Pacers, and the influence of local sports stars such as Caitlin Clark driving betting interest.

Despite strong growth, Indiana has faced challenges such as stalled online casino legislation and opposition to gaming expansion proposals. Revenue trends have fluctuated, with some months showing year-over-year increases in handle and revenue, while others saw declines. The state continues to evolve its sports betting ecosystem with new operators entering the market, regulatory adjustments, and ongoing legislative discussions shaping the future of gambling in Indiana.
