INDIANAPOLIS – Indiana is the latest state to legalize sports gambling.

Republican Gov. Eric Holcomb signed legislation Wednesday allowing sports betting and allowing the construction of two new casinos in the state.

Indiana, Montana and Tennessee have legalized sports gambling this year. Six other states did so last year after a U.S. Supreme Court ruling that allowed it nationwide. Hundreds of billions of dollars are exchanged annually in sports betting, most famously on events like the Kentucky Derby and the Super Bowl. Prop bets have become a Super Bowl staple in recent years, and the new bill would allow for Indiana residents to make these wagers legally within the state.

Indiana’s sports wagering could start in September. Gamblers can place bets using mobile devices after registering with an Indiana casino. It was not initially stated as to how each sport would be available to wager upon, likely to materialize as betting organizations begin to form within the state.

The new law also authorizes the Lake Michigan casino in Gary to move to a new site along Interstate 80-94 in that city and establishes the process for the opening of a casino in Terre Haute.
