Missouri officially launches sports betting on Monday, December 1, 2025. Before placing a bet, you should know the legal betting age in Missouri, which is 21 years old. This marks the first day anyone in the state can legally wager online or in person through Missouri sports betting apps.
If you plan to sign up early or claim any Missouri sportsbook promos, you must be 21 years or older to participate. Pre-registration is now open, giving anyone located in Missouri time to create accounts and verify their eligibility before wagering officially begins on December 1, 2025.
What Is the Legal Age to Bet on Sports in Missouri?
Anyone looking to place a sports bet must be at least 21 years old. This is the legal betting age in Missouri and applies to all online and in-person sportsbooks.
When you create an account with any upcoming Missouri sportsbook, you must submit personal information, including the last four digits of your Social Security number, to confirm your age and identity. These verification steps are standard nationwide for regulated sportsbooks and Missouri betting apps.
If you’re younger than 21, you must wait until your 21st birthday to place a real-money wager. Anyone under the legal betting age in Missouri won’t be able to sign up for or deposit funds with Missouri sportsbooks until they turn 21.
When Will Sports Betting Be Live in Missouri?
Sports betting will be live in Missouri on December 1, 2025.
That launch date marks the beginning of a new era for Missouri sports betting, with mobile apps and approved operators ready to start taking wagers. You can now pre-register and take advantage of early sign-up bonuses offered by the state’s licensed sportsbooks.

Hockey fans can wager on the St. Louis Blues, while college sports enthusiasts can place bets on the Missouri Tigers across football, basketball, and more. These are just some of the Missouri sports teams to bet on through licensed sportsbooks and Missouri sports betting apps.

With partnerships already in place between bet365 and the Cardinals, and Underdog with both the Royals and Blues, the local sports connection runs deep.
