BetMGM is launching its sportsbook in Missouri with an early sign-up promotion and a huge welcome offer to new customers before the state officially launches legal online sports betting on December 1, 2025. The offer- a combination of a pre-registration credit and a first-bet safety net is meant to get Missouri bettors through the door when apps go live.
What BetMGM is offering
BetMGM’s Missouri pre-launch promotion includes a $100 pre-registration bonus to users who create an account and make a qualifying deposit prior to the launch, and the company's flagship first-bet insurance: up to $1,500 back in bonus bets in case of a first-bet loss by a new user. That mix is effective in providing new customers with bonus liquidity on day one and minimizing the risk of first-time app usage. The same structure is listed in several media outlets that cover Missouri promos.
When you can sign up and bet
Signups actually started in November, around mid-month, with some sources reporting openings as early as November 17, 2025. The sign-ups primarily allowed Missouri residents to complete their identity verifications, download the BetMGM app (iOS/Android), and deposit money before the launch on December 1. Although the apps and accounts will be open for services before December 1, actual wagering will not start until December 1 when legal online and retail sportsbooks come into operation throughout the state.
How to claim the bonus (quick steps)
- Install the BetMGM Sportsbook app or go to the BetMGM site and select Missouri when asked.
- Register your account and verify your ID within the pre-registration period. It is reported that there is a minimum deposit required on the pre-reg bonus (usually $10).
- Add any necessary promo code when available by the affiliate or BetMGM (affiliate sites have listed a few codes related to partner promotions).
- Make your first real-money bet on or after December 1. In case the bet is lost, the insurance will reimburse up to the mentioned limit in bonus bets. The pre-registration credit is usually provided on the launch day.
Remember that the terms differ: bonus-bet expiry windows (usually seven days), minimum qualifying wager, and any game or market restrictions are all detailed in the full terms and conditions - always read them before accepting a promotion.
Where BetMGM will operate in Missouri
BetMGM is also expanding into Missouri, partnering with local casino operators. In May 2025, BetMGM partnered with Century Casinos for a long-term deal - this move brings the BetMGM platform to locations such as Century Casino & Hotel Cape Girardeau. While at it this sportsbook will establish its local retail presence there.
That collaboration will enable BetMGM to provide online and in-person betting services across the state.
Who’s eligible, and responsible-gaming resources available
Missouri law states that bettors should not be below the age of 21 years if at all they want to make sports wagers. The sportsbook also offers direct access to responsible-gaming tools and support services, such as the national helpline 1-800-GAMBLER.
Players can also limit their deposits, time, and wagering, and can self-exclude using in-app controls at BetMGM. Any person who has a history of gambling-related problems is highly advised to use the resources mentioned above before opening an account or depositing money.
Things to check before you sign up
- Geolocation: To open an account and bet, you have to be physically within the state of Missouri.
- Fine print: Find minimum deposit, bonus bet expiry, and limited markets (not all promotions cover futures, parlays, or in-play wagers).
- Verification time: Make sure that you complete ID checks during the pre-registration period to prevent delays on the launch day.
- Retail or online: In case you want to wager in person, BetMGM’s Century Casino partners will offer retail sportsbook windows once retail licensing is finalized.
