Mississippi sports betting officially arrived in August 2018, but only at retail sportsbooks in the state. The first two to open were at Beau Rivage and Gold Strike casinos, owned by MGM Resorts. So it only make sense that the first sportsbook app to launch in the state is BetMGM Sportsbook, albeit three years later in September 2021. For Mississippi, the 2018 SCOTUS decision represented the final piece necessary to regulate an industry that state lawmakers have been moving toward legalizing for over a year. However, the state’s online sportsbook industry comes with a betting restriction that BetMGM users must follow. While you can register from anywhere in the state, you must complete the sign-up process and place all bets in person at one of MGM’s Mississippi casinos. Outside of those locations, users will be treated as out-of-state player and be denied access. Here’s more about how to bet on sports in Mississippi.
