How Do You Pre-Register With Missouri Sports Betting Apps?

Pre-registering with Missouri sports betting apps takes only a few minutes. Use any link in the table above to open one of the top Missouri sportsbooks and start the process. While each of the Missouri sportsbook promos has its own specific steps, the overall path is essentially the same:

• Verify your identity and location by submitting the required details.
• Enter a Missouri sportsbook promo code if the platform asks for one.
• Confirm that you’re opting into the pre-registration bonus.

After you pre-register, deposit funds, and explore betting markets for the NFL, college football, and more. The only thing you can’t do is place a wager. Missouri sportsbooks use geolocation to prevent wagers until online Missouri sports betting officially launches. Once the best MO sports betting apps go live on Dec. 1, you’ll be able to place your first bet instantly.

When does Missouri sports betting go live?

Missouri sports betting goes live on December 1, 2025. Voters approved online wagering in 2024, and the year-long wait is finally nearing its end. By pre-registering with Missouri sports betting apps now, you can get comfortable with your preferred platform before placing your first wager on launch day.

When Missouri sports betting officially opens, bettors can bet on any major sport available in the Show-Me State. Back the Kansas City Chiefs as Patrick Mahomes and Travis Kelce push for a fourth Super Bowl run, or place wagers on the St. Louis Blues throughout the NHL season. From NFL and NHL to NBA, college sports, and more, every major market will be available once the Missouri sports betting apps go live on Dec. 1.

Can I bet on college sports in Missouri?

Yes, once Missouri sports betting goes live in December, you can wager on any college sporting event. The main restriction with Missouri sports betting apps is that player prop bets involving athletes from MO colleges are prohibited. All other college markets will be available when the state officially launches on Dec. 1.

What to bet on with Missouri sports betting apps on launch day

Once Missouri sports betting launches on Dec. 1, you can put your pre-registration bonuses to use immediately. New sign-ups with Missouri sports betting apps can access various wager types, including pre-game bets, live wagers, parlays, props, straight bets, and nearly every other major betting option.

Here’s how each Missouri sportsbook promo works, depending on the offer you claim:

• Bet-and-get offers: Place your qualifying first wager to unlock your bonus bets.
• No Sweat Bets / “first bet on the house”: Place your first bet and, if it loses, receive your stake back in bonus bets or FanCash.

Each of the Missouri betting apps available during pre-registration comes from a top-rated online sportsbook in North America.
