On Thursday, December 4, 2025, BetMGM Sportsbook's official launch of operations in Missouri continues. This significant expansion for the "King of Sportsbooks" opens with a headline-grabbing welcome offer: the BetMGM bonus code CUSE100 unlocks a $1,500 First Bet Offer for Missouri residents, and a $150 "Bet and Get" in four other states.
This development represents a major deviation from the standard offers seen in older markets. By activating the BetMGM bonus code in Missouri today, new users secure a massive safety net for their initial wager, making this $1,500 offer one of the most flexible and valuable launch promotions in the country.
The launch week arrives at a strategic moment, coinciding with the St. Louis Blues season and the NFL playoff push. The BetMGM bonus code structure for Missouri is designed to give bettors confidence when placing their first substantial wager.
Unlike "bet and get" deals that offer smaller fixed amounts, the BetMGM bonus code CUSE100 allows new customers to wager up to $1,500 on their first bet, receiving their entire stake back in bonus bets if it loses.
Key Deal Terms:
For users outside of the newly launched Missouri market, BetMGM offers different promotions based on location. In established markets like Pennsylvania, New Jersey, Michigan, and West Virginia, new users who activate the BetMGM bonus code CUSE100 can secure a Bet $10, Get $250 in Bonus Bets (or similar "Bet & Get" variants). While consistent, the Missouri launch offer provides a much higher ceiling for bettors looking to maximize their first play.
The official activation of the BetMGM bonus code comes as the NFL season heats up with critical Week 14 action. Missouri bettors can utilize their protected first wager on tonight's Thursday Night Football matchup or the St. Louis Blues game to trigger the offer.

If it misses, your stake returns to your account as bonus bets, keeping you in the game for the St. Louis Blues vs. Boston Bruins (7:00 PM ET) or Sunday's Chiefs vs. Texans showdown. All odds above subject to change.
