As of Monday, December 1, 2025, legal online betting has officially arrived in Missouri—and FanDuel is celebrating launch day with a massive new user offer built specifically for Cyber Monday. The latest FanDuel promo code instantly delivers $300 in Bonus Bets after placing a simple $5 wager, making it one of the strongest Missouri sportsbook bonuses available on Day 1.

Unlike previous offers that required your first wager to cash, this FanDuel promo code guarantees the full $300 in bonus bets no matter what happens with that initial bet.

With the St. Louis Blues taking the ice on opening night against the Anaheim Ducks, Missouri users now have a marquee local matchup to bet on immediately.
