Is Sports Betting Legal in Montana? Yes, But Not From Home (2026)

Yes, sports betting is legal in Montana, and there is exactly one book: Sports Bet Montana, run by the state lottery. You can install its app anywhere. You can register from your kitchen table, upload your ID, deposit money, watch live odds, build a parlay, and withdraw your winnings, all without leaving the house.

What you cannot do is place the bet. For that you have to be standing inside a licensed bar, tavern, casino, or restaurant. The operator says both halves out loud in its own FAQ.

That restriction is unusual not because it exists, but because of where it is written. It is not a regulation someone could repeal. Here is how Montana actually works.

Quick facts

The catch is a definition, not a rule

Most states that limit mobile betting do it through a regulation or a tribal contract. Montana wrote the limit into the definition of the license itself.

Under MCA 23-7-103(11), a “sports wagering license” authorizes mobile wagering only where the bet is “initiated and received or otherwise made exclusively within the physical confines using location-based services of the single approved sports wagering facility.”

That placement is the whole story. Because the restriction sits in a statutory definition rather than in the administrative rules, the State Lottery and Sports Wagering Commission cannot lift it by rulemaking. Changing it takes a bill. And Montana’s Legislature meets only in odd-numbered years, so the next scheduled opportunity is 2027.

Compare Nevada, where the in-person requirement is a Gaming Commission regulation that the Commission could delete tomorrow without asking any legislator. Montana’s takes a statute.

The Nevada mirror

Nevada and Montana both make you show up. They make you show up for opposite reasons, and putting them side by side is the clearest way to understand either one.

• In Nevada you appear in person once, prove who you are, and then bet from anywhere in the state forever after.
• In Montana you prove who you are from your couch, and then you never get to bet from it.

Nevada’s friction is at the front door. Montana’s is at every single wager.

Both states also close dormant accounts, and both traps work the same way. Montana suspends and closes an account after 18 consecutive months with no wagers (Nevada’s clock is 16 months). In both, the trigger is wagers. Logging in, depositing, and withdrawing do not reset it.

What you actually do

1. Download the app or use the website, from anywhere. Registration is fully remote and completes through an emailed activation link. There is no in-person verification step anywhere in the process.
2. You must be 18.
3. Fund the account with cash, check, or a debit card. Credit is barred by statute (MCA 23-7-302(3)), and debit deposits are capped at your bank’s daily withdrawal limit.
4. Build your bet slip at home if you want. This is explicitly allowed.
5. Walk into a licensed location and submit it. The Lottery reported 568 sports-betting sales agents in fiscal 2025, up from 541. In practice these are bars, taverns, casinos, and restaurants, not dedicated sportsbooks.
6. Or skip the account entirely and use a kiosk. A kiosk wager requires no account at all.

On limits, be careful with the numbers you see elsewhere. Nearly every competing page prints “$250 at a kiosk, $1,000 on the app.” That pair traces to launch-day local news reporting from March 2020 quoting the Lottery’s communications manager, describing a setting that varies. Today there is no published maximum bet. Limits are discretionary, vary by sport, league, and odds, and are shown in the app. The one hard published figure is a payout cap of $100,000 per wager including stake. Larger wagers are accepted; the cap is on what comes back.

College betting: unrestricted, and resting on nothing

Montana restricts nothing about college wagering. Not in-state teams, not player props, not anything. The Grizzlies and the Bobcats are on the board, and you can see exactly how much money that moves, because the Lottery prints it: $163,159 across 4,937 bets on the rivalry game.

What makes Montana unusual is not the permissiveness. It is that the permissiveness rests on no legal instrument at all. There is no statute limiting eligible events. The sports wagering rulebook is three administrative rules, none of which addresses what you may bet on. The Lottery’s own published game parameters do not contain the word “college.”

This is the third and most extreme version of a pattern we keep finding. Maryland’s college prop ban lives in an approved-events catalog rather than in regulation. Indiana’s lives in an executive director’s directive. Both can change without a legislature. Montana goes one step further: there is nothing to change. The Lottery could stop listing college markets tomorrow simply by not listing them.

Montana is among the most permissive states in the country here, alongside Nevada and North Carolina.

The part that sounds like a contradiction

Montana banned internet gambling and made it a felony, while running its own betting app.

In 2025 the Legislature passed SB 555, signed by Gov. Greg Gianforte on May 12, 2025. It wrote online casinos into the statutory definition of internet gambling and attached felony liability, up to $50,000 and up to ten years, to operating an illegal internet gambling site.

Montana still has a mobile app because of a clause almost nobody reads. The definition of “internet gambling” does not include “the state lottery provided for in Title 23, chapter 7.” Montana did not carve out an exception for mobile sports betting. It carved out itself.

One caution, because this gets misreported: the statute’s text says online casinos. The words “prediction” and “event contract” do not appear in it. Anyone telling you SB 555 banned prediction markets is describing an enforcement position, not the words of the law.

Prediction markets: Kalshi sued Montana

In most states we cover, the state sues the prediction market. In Montana the direction is reversed.

Montana’s Gambling Control Division, a different agency from the Lottery, issued cease-and-desist orders to prediction markets on March 26, 2025 and again on April 6, 2026. On April 12, 2026, KalshiEX sued the state in federal court in Helena (KalshiEX LLC v. Knudsen, No. 6:26-cv-00028), arguing that federal commodities law preempts Montana gambling law.

The suit names eight state officials, and there is an irony in the caption that no coverage mentions: all five members of the State Lottery and Sports Wagering Commission are defendants. The body that oversees Montana’s own sportsbook is a party to the case against its unlicensed competitor.

Nothing has been decided. The case has been stayed twice, with a joint status update due August 21, 2026. No court has ruled on preemption or on any injunction. Montana is also not one of the nine states the federal government has sued over prediction-market enforcement, and until recently it had joined none of the multistate coalitions. That changed on July 27, 2026, when Attorney General Austin Knudsen signed a comment letter from 44 states and the District of Columbia urging the federal regulator to rewrite its proposed prediction-markets rule. Montana still litigates alone, and it is the state whose own case was brought against it rather than by it.

Montana sits in the Ninth Circuit, which is holding Kalshi’s appeal of its Nevada loss, argued in April 2026 and undecided. That ruling would land directly here. Nationally, no federal appeals court has yet ruled on the merits of whether federal commodities law overrides state gambling law.

There is a contrast worth sitting with. Montana’s legal, regulated sportsbook requires you to be inside a bar. A prediction market offering contracts on the same game is reachable from a couch anywhere in the state.

Where Montanans can use a real app

Montana borders four states. Exactly one of them has a working sports betting app.

Wyoming is the answer. The other three fail for three different reasons, and in each case there is no legal app to download, not merely a less convenient one. Geolocation is checked on every bet, so an account registered elsewhere will not take a wager placed from inside Montana.

What Montana was before 2019

Montana’s history here is genuinely strange, and it explains why the state was exempt when Congress froze sports betting nationally.

When PASPA passed in 1992, four jurisdictions were exempt. Nevada kept full sportsbooks. Delaware and Oregon kept state lottery parlay games. Montana’s exemption preserved something different in kind: licensed sports pools, authorized by statute in 1974, and Calcutta auction pools, authorized in 1987, both run privately in bars under state license rather than by the state itself.

The Montana Lottery was created in 1985 and approved by voters in November 1986, selling its first ticket in June 1987. It sold no sports product at all until 2008, and did not run a sportsbook until 2020.

HB 725 (Chapter 284, Laws of 2019) authorized sports wagering inside the lottery chapter, and Sports Bet Montana launched in March 2020, days before the pandemic shut down the sports calendar.

Montana also still has a provision, on the books since 1991, allowing wagering on who most accurately predicts the timing of a weather event. A state that wrote a weather prediction market into law thirty-five years ago is now in federal court with a prediction-market exchange.

The size of it

Montana’s entire sports betting handle for fiscal 2025 was about $66 million. New York takes more than that in a day. The biggest event of Montana’s year, all three weeks of March Madness, drew $2.35 million across 82,400 bets.

Unusually, Montana shows its working: the Lottery publishes handle, payout, and gross gaming revenue every Monday, which most state regulators do not. It also deletes the file after twelve months.

What could change

• August 21, 2026: the joint status update in the Kalshi case, the most likely date for Montana’s prediction-market posture to move.
• Any day: the Ninth Circuit ruling, which binds Montana directly.
• Any day: a tribal sportsbook. Two Montana compacts already authorize tribal sports wagering, and none is known to have opened. Those compacts also confine play to the premises, by an entirely separate legal instrument.
• 2027: the Legislature returns. It is the only scheduled route to statewide mobile, and bills have been introduced and failed before.

FAQ

Can I bet on sports from my phone at home in Montana? No. You can do everything except place the bet: register, deposit, browse odds, build a slip, withdraw. Submitting the wager requires you to be physically inside a licensed location.

What betting apps work in Montana? Only Sports Bet Montana, the state lottery’s own product. FanDuel, DraftKings, BetMGM, and Caesars do not operate here, and there is no license for them to apply for.

How old do you have to be to bet in Montana? 18. Montana is one of only five US jurisdictions at 18, with New Hampshire, Rhode Island, Washington D.C., and Wyoming. The age is not a sports betting decision: the 2019 law inserted sports wagering into the lottery’s existing age line from 1985, so the 18 is inherited.

Can I bet on the Griz or the Bobcats? Yes, including player props. Montana places no restrictions on college wagering at all.

Is daily fantasy sports legal in Montana? Not online. A 1991 statute makes internet and telephone fantasy sports wagering unlawful, which is why the national DFS apps do not serve the state.

Is Kalshi legal in Montana? Contested and unresolved. Montana ordered prediction markets to stop twice, Kalshi sued the state in April 2026, and the case is stayed with nothing decided. Check the platform’s own terms rather than a comparison site.

Where is the nearest place I can use a normal betting app? Wyoming. It is the only one of Montana’s four neighbors with statewide online betting.
