Missouri’s online sports betting launch is approaching quickly, with legal sportsbooks set to go live on Dec. 1, 2025. But bettors won’t have to wait until launch day to get prepared. Pre-registration opens Nov. 17, giving new users the chance to download the app, create an account and lock in their welcome bonus before wagering officially begins.

In this pre-launch window, the BetMGM Sportsbook Missouri promo/bonus code offers one of the strongest early sign-up deals on the market: Get up to $1,500 back in Bonus Bets if your first wager loses, plus an additional $100 in Bonus Bets when you make a pre-launch deposit before December 1. This is strictly a pre-registration period — users can secure their bonus and get fully set up now, but betting won’t open until launch day.

Online sports betting is officially coming to Missouri after voters approved legalization in the 2024 general election. The state’s licensed sportsbooks are set to launch on December 1, 2025, giving residents access to safe, regulated online wagering for the first time.

Ahead of launch, pre-registration opens November 17, 2025, allowing new users to sign up early and lock in exclusive welcome offers. BetMGM Sportsbook has already been approved to operate in Missouri and is expected to be one of the first legal sports betting apps available on day one.

By signing up through the Missouri BetMGM promo/bonus code, new customers can secure their bonus now and have it ready to use as soon as betting goes live on December 1. For more information, visit the Missouri Sports Betting page.

Pre-registering locks in the Missouri BetMGM Sportsbook promo/bonus code ahead of launch, ensuring your bonus is ready to activate on Dec. 1 — either automatically or after you place your first qualifying wager. This early signup window lets you download the app, verify your ID and location, and get fully set up before Missouri sports betting officially goes live.

Download the BetMGM app and sign up starting November 17 to secure your welcome bonus before launch.
