What Gambling Is Legal in Missouri

Sports Betting in Missouri

Sports betting began in Missouri on December 1, 2025, thanks to Amendment 2. Is sports betting legal in Missouri today? Yes, both retail and online. Voters approved this change in November 2024 by a very close margin of about 50.05%. That was one of the narrowest votes for this type of law in the country.

Missouri Online Casinos

Missouri online casinos aren't legal. If you search for “online slots real money Missouri”, you will not find a legal option yet. Amendment 2 is part of the state constitution. To legalize online casinos, Missouri would need another ballot measure, just like the one that made Missouri sports gambling legal.

Daily Fantasy Sports in Missouri

Paid daily fantasy sports have been legal and regulated in Missouri since 2016. It was several years before sports betting became available.

Prediction Markets Sit Outside State Law

The CFTC regulates prediction markets at the federal level as event-contract exchanges. Missouri law does not address them, and there is no state license for this type of gambling.

How Old Do You Have to Be to Gamble in Missouri

How old do you have to be to gamble in Missouri? 21, for casino gaming, sports betting, and paid daily fantasy sports. The Missouri Lottery sets its own age at 18.

Who Regulates Gambling in Missouri

The Missouri Gaming Commission is responsible for licensing and overseeing both sports betting and paid daily fantasy sports. If you have a complaint, this is the agency to contact.

Reach the Missouri Gaming Commission directly for any complaint.

Support runs through the Missouri helpline at 1-888-BETS-OFF (1-888-238-7633), funded by the Department of Mental Health. Licensed sportsbooks in Missouri also show the national 1-800-GAMBLER number. You can find more information on our responsible gambling page.

Where to Bet in Missouri

Ten sportsbooks were approved when Missouri launched sports betting. DraftKings and Circa Sports have untethered licenses, so they do not need a casino partner. The other sportsbooks are connected to one of Missouri's 13 riverboat casinos or to a professional sports team.

This is the practical answer to “Is online gambling legal in Missouri?” Sports betting runs through these ten operators specifically.

Paid daily fantasy sports have a completely separate licensing process. Missouri's DFS options cover who's currently available.

There is no Missouri-specific page for prediction markets because they are not covered by state law. The prediction market regulatory tracker is the right place to check current status instead.

Missouri State Tax on Winnings

In Missouri, gambling winnings are considered ordinary income. The state tax rate is graduated and will reach up to 4.70% in 2026. Missouri does not tax capital gains under HB 594, but this exemption does not apply to gambling winnings. These remain fully taxable as ordinary income.

What Gets Withheld and When

When you get paid, the operator takes out some money for taxes right away. That amount might not match what you actually owe when you file your tax return.

Pending Missouri Gambling Legislation

Why Online Casino Needs a Ballot Measure

Amendment 2 is part of the Missouri Constitution. Because of this, Missouri online casinos cannot become legal through a standard bill. Legalizing them would require another ballot measure.

What Is Not Moving

As of September 2026, Missouri has not introduced any bills to legalize online casinos. Bills for video lottery terminals have failed several times over the years. The 10% tax on adjusted gross sports betting revenue, which includes a promotional deduction, will likely be reviewed after a full year of revenue data is available.

Missouri's sports betting market has been active for eight months. In the most recent month, about $246.8 million was wagered, bringing in $2.2 million in state tax revenue. This was the highest revenue month so far, even though the total amount wagered was lower.
