Is online sports betting legal in Montana?

Sportsbooks in Montana

None of the sportsbooks on vigged (DraftKings, FanDuel, BetMGM, Caesars Sportsbook, Hard Rock Bet, theScore Bet and Circa Sports) can take online bets from Montana. With your state set to MT, the boards still show US sportsbooks' prices side by side, unranked.

Offshore sites such as Bovada are not licensed in Montana or any other state: no regulator holds your deposits or settles disputes. vigged shows offshore prices unranked and never links to them.

Prediction markets: Kalshi and Polymarket US

Kalshi’s sports contracts are contested in Montana: state regulators have challenged them, and reports on whether they are open to Montana users disagree. Check Kalshi’s app for your account before counting on it.

Polymarket US blocks its sports markets for users in Montana, though other markets may be open. Polymarket’s international site does not serve US users.

How they differ from a sportsbook: you buy a contract that pays $1 if the outcome happens, priced in cents (58¢ is a 58% chance), from other traders rather than a bookmaker. Fees take the place of vig, the minimum age is 18, the same as at sportsbooks here, and the legal fight over sports contracts is still moving.
