Is crypto sports betting legal in Missouri?

What's legal

Missouri voters approved Amendment 2 in November 2024. It added section 39(g) to Article III of the state constitution and made the Missouri Gaming Commission the regulator. Sports betting went live on December 1, 2025. You must be 21 or older, and online bets are accepted only while you are physically in Missouri.

Licenses are tied to casinos and professional sports teams, apart from two untethered licenses that went to DraftKings and Circa Sports. The Commission's May 2026 sports wagering report lists eight mobile licensees with reported wagers: bet365, BetMGM, Caesars, Circa, DraftKings, Fanatics, FanDuel and Penn Sports Interactive. Retail sportsbooks run at casinos such as Ameristar, Argosy, Harrah's and Hollywood. Almost all of the action is online: of the roughly $543 million wagered in December 2025, about $539 million went through apps.

Crypto and offshore sites

We found no Missouri rule that allows crypto deposits at licensed sportsbooks, and the licensed apps fund accounts with cards, bank transfers and similar dollar methods. If you hold crypto, you would normally sell it for dollars first. That sale can be a taxable event on its own.

Offshore crypto sportsbooks are not licensed in Missouri or in any other US state. If you use one, no state regulator stands behind your balance or your payout, and a dispute over a withheld withdrawal has nowhere official to go. The Commission's license list is the check: if a sportsbook is not on it, it is not licensed to take your bet.

What's changing

In September 2026, Attorney General Catherine Hanaway ordered Kalshi, Polymarket, Crypto.com, Novig, Underdog and Robinhood to stop offering sports event contracts to Missourians. Her position is that relabeling a sports bet as an event contract does not avoid state law, and that anyone offering sports wagering in Missouri needs a Commission license, must pay the required taxes and fees, and must keep under-21s out. Kalshi disputes that, saying its exchange works differently from a sportsbook. We found no court ruling in Missouri on the question yet.

Tax on winnings

Gambling winnings count toward your Missouri return through federal adjusted gross income. The Department of Revenue lists a top state rate of 4.7 percent for 2026, on top of federal tax. Keep a record of wins and losses and ask a tax professional about your own situation.
