Hoosiers pumped more than $5.72 billion into online betting sites in 2025. That is nearly twice as much as gamblers in Indiana spent betting on sports apps in 2021, the state’s first full year of online sports betting.

Since sports betting began in 2020, Indiana residents have wagered more than $17 billion on sports — more than 90% of it coming from bets placed online.

During the same timeframe, enrollment in Indiana’s Internet Self-Restriction Program (ISRP) has surged by over 3,500%, signaling a sharp rise in problem gambling coinciding with the arrival of online sports betting.

Young adults are disproportionately affected: 77% of ISRP participants are under the age of 40, compared to just 15% of those enrolled in Indiana’s casino Voluntary Exclusion Program (VEP).
