Is Online Gambling Legal in Montana?

Like many states, Montanas gambling laws were outdated and didn’t make reference to online gambling. This led to a grey area surrounding the activity and residents were welcomed in by numerous offshore sites. The definition of illegal gambling was updated in 2005 and removed loopholes which were being exploited by unauthorised sites. This defined all forms of online gambling as illegal. 

Montana is one of the friendliest states when it comes to retail gambling though. Sports betting became legal in 2020 with only one app available through the state's lottery. There are charitable bingo games, multiple lotteries and sweepstake gambling is also permitted. Live horse and dog race wagering are legal too, if bets are placed in licensed venues.

Despite Montanas sparse population it does have 300 tribal run and commercial casinos. Due to this bustling industry, it isn't looking likely that online gambling will be legalised anytime soon.

Minimum Legal age to Gamble in Montana

Montana is very lenient when it comes to its minimum legal gambling age. It’s one of very few states which permits all forms of gambling from the age of 18. It’s worth bearing in mind though that some gambling venues will only allow those aged 21 or above to enter, due to liquor licensing laws.

Who Regulates Casinos in Montana?

The Montana Lottery regulates sports betting within the state and of course the state lotteries too. The Gambling Control Division oversees all other forms of gambling except for pari-mutuel horse race betting which is governed by The Board of Horse Racing.
