Quick Answer: Is Sports Betting Legal in Montana?
Yes, sports betting is legal in Montana, but its structure is unique. The Montana Sports Wagering Act (MCA § 23-5-802 et seq.), passed in 2019 via SB 330, legalized sports betting. The SportsBet Montana app, launched in March 2020, is the state's only legal platform.
Key aspects of Montana's model include:
- Exclusive State Operator. The Montana Lottery exclusively operates sports betting. No private commercial sportsbook, such as DraftKings, FanDuel, BetMGM, or Caesars, holds a license to accept Montana sports wagers.
- No Remote Wagering. The app uses geofencing. Bettors must be physically inside a licensed Montana retailer—typically a bar, casino, or other establishment with a qualifying lottery license—to place a bet.
- Minimum age is 18. The minimum age for sports wagering is 18, as established by the Montana Sports Wagering Act (MCA § 23-5-802 et seq.).
- Daily fantasy sports (DFS) operate under a separate legal framework. DraftKings and FanDuel accept Montana players.
