What does Montana law say about sports betting?
Legal under a 2019 law and run by the Montana Lottery as Sports Bet Montana. Betting started in mid-March 2020 at kiosks in licensed locations (about 180 locations planned) and through the lottery's mobile app. Source: Montana Public Radio - Sports Betting Begins In Montana Just As Coronavirus Cancels Seasons (2020-03-12), checked October 6, 2026.
- Regulator. Montana sports wagering is run under Montana Code Title 23, chapter 7 (State Lottery). Section 23-7-104 makes it lawful when conducted under that chapter and the rules of the state lottery and sports wagering commission, a five-member body appointed by the governor. Source: Montana Code Annotated 23-7-104 (Authorization of sports wagering), checked October 6, 2026.
- Minimum age. Sports Bet Montana, the Montana Lottery's sportsbook, says players must be 18 years of age or older to play. The Lottery's player-club terms also state an 18-or-older eligibility. Source: Sports Bet Montana (Montana Lottery), checked October 6, 2026.
- In-person and tribal rules. Montana's model is lottery-run: the Montana Lottery operates Sports Bet Montana as the state's exclusive sportsbook, mostly through retail locations (the site lists over 550 statewide, such as casinos, bars and liquor stores), plus a mobile app. Source: Sports Bet Montana (Montana Lottery), checked October 6, 2026.

What courts and officials have done about exchanges in Montana
- On Aug. 27, 2026, U.S. District Judge Donald Molloy denied Kalshi's motion for a preliminary injunction against Montana's enforcement of its gambling laws, saying Kalshi's repeated agreements to stay the case undercut its claim of irreparable harm. The underlying case continued at that point. Source: SportsBettingDime, checked October 6, 2026.
- On Sept. 17, 2026, Kalshi and Montana filed an agreement to dismiss the federal suit. Montana must give 30 days' notice before enforcing its gambling laws against Kalshi, and reports say that step awaits the Ninth Circuit's handling of Kalshi's rehearing request.

Contested states are due for a recheck by October 16, 2026. See the prediction-markets guide for how exchanges differ from sportsbooks.
