FAQ - MT Sports Betting Bonuses
Is online betting legal in Montana?
Yes and no, but mostly no. The short answer is that the big national sportsbook brands are not available legally in Montana.
It is however possible to bet online via Sports Bet Montana, which is operated by the state lottery. This is not comparable to normal online betting though, as the player has to place the bet while physically located at a licensed retailer, such as a casino or bar, with a gambling kiosk.
Are online casinos legal in Montana?
Internet gambling for real money is illegal in Montana, and Senate Bill 555 explicitly banned online casinos in 2025.
Are there legal betting alternatives in MT?
Yes, but the options are very limited. Montana has taken as stance against all types of internet gambling with real money, essentially prohibiting a majority of the operators from accepting players from the state.
Legal options include CFTC-licensed prediction market sites operating under federal regulation, such as Kalshi, and free-to-play social sportsbooks that require no deposits, such as Fliff.
Can you win real money online in Montana?
Yes, but with limited options. Online gambling is strictly regulated in Montana. It is possible to visit some social/sweepstakes sportsbooks, but only with the option of playing for free, and without redeemable cash prizes.
Prediction markets is the only option for players hoping to win some real cash when playing. The big prediction apps and sites have a CFTC-license, and operate legally under federal law. They also offer predictions in the form of bought- and traded contracts, not bets and games. This means that while not specifically authorized in Montana, they are not illegal.
