Getting ready for sports betting in MO

If you’re reading this page, then you are probably gearing up for the launch of legal sports betting in Missouri. This won’t actually happen until December 1, 2025, but it looks like there could be anywhere up to 10 online sportsbooks getting ready to take your bets.

This leaves you with the question of which online sportsbook to sign up with. So what we’ve done here is picked two excellent sportsbooks, plus one DFS brand to mix things up:

BetMGM - A true heavyweight in the sports betting universe

This massive sportsbook has wasted no time in getting our attention with an awesome pre-launch offer for all MO residents who sign up before 1 December, 2025. Doing this will unlock a deal that gives you $100 in bonus bets, and you’ll also get the regular welcome offer that’ll refund your first bet, if it loses, with up to $1,500 in site credit.

Everything else about BetMGM is as you’d hope it would be with competitive pre-match and live odds on dozens of sports. The brand is also great at putting on generous odds boosts for the biggest sporting events, and you’ll have great fun creating same game parlays on the user-friendly app.

Caesars Sportsbook - Trusted brand for all forms of sports betting

How to verify your age for betting in Missouri

Every legit Missouri sports betting app will require you to verify your identity before you can do things like setting up your account, making deposits and placing bets.

This verification process aims to ensure that you are at least 18 years old, although you don’t necessarily have to be a resident of Missouri. The app will contain geolocation software to ensure that you are betting from within state lines.

Many sportsbooks will have an automated verification procedure that is completed by a third-party agency who’ll carry out a quick check based on personal information like your name, home address and social security number. However, there is a chance that you may be called upon to submit further documentation:

• Proof of identity like your passport or driver’s license
• Proof of address such as a bank statement or utility bill from within the past three months
• A selfie showing a clear image of your face
