Missouri Sports Betting Is Live: What You Need To Know
Summary
Missouri’s long-awaited legal sports betting market launched at midnight on Monday. The Missouri Gaming Commission initially licenced 10 operators for day-one availability, though Underdog withdrew and is offering sports predictions instead, leaving nine active sportsbooks at launch. Missouri becomes the 32nd US jurisdiction with online sports betting.
The launch mixes national and niche brands — including bet365, BetMGM, Caesars, DraftKings, Fanatics, FanDuel, Circa, Kambi (brand partner TBD) and theScore Bet — and aims to reclaim bets from Missourians who crossed into Illinois. Missouri taxes sportsbooks at 10% of net revenue and analysts project the market could mature to roughly $4.6bn in annual handle and around $500m in gross revenue, with an estimated annual tax take near $35m after promotional deductions.
The road to launch was protracted: a narrow referendum (50.05% approval) followed years of legislative delays and regulatory holdups. Regulators set 1 December as the final allowable launch date.
Key Points
- Market launch: Online sports betting in Missouri went live on 1 December 2025.
- Operators: Nine sportsbooks launched after Underdog pulled out of the market.
- Brands on day one include bet365, BetMGM, Caesars, DraftKings, Fanatics, FanDuel, Circa, Kambi (partner), and theScore Bet.
- Tax regime: Missouri set a 10% tax on sportsbook net revenue, seen as operator-friendly.
- Market potential: Estimated mature handle of ~$4.6bn and gross revenue over $500m; taxable revenue and promotions will affect final tax receipts (~$35m est.).
- Cross-border impact: Launch may reduce bettors travelling to Illinois, where a per-bet fee has increased costs for customers.
- History: Approval came via a close referendum after years of stalled legislation and regulatory delays.
Why should I read this?
Because if you live in Missouri, run betting markets, work with sportsbook affiliates, or just care about how state rules shift bettor behaviour, this matters — and fast. We’ve boiled down who’s in, how the tax works, and what it means for people who used to pop over to Illinois to place bets. Short, sharp and useful.
Context and Relevance
This launch is part of the steady national rollout of legal sports betting: Missouri is the 32nd jurisdiction, and its operator-friendly 10% tax and allowance for promotional deductions make the market attractive to big brands. The timing matters because Illinois recently added a per-bet fee that drove some bettors across state lines — Missouri’s cheaper options could reverse that flow, changing regional handle distribution.
For operators and affiliates, the mix of national and niche entrants shows varied market strategies: established apps (DraftKings, FanDuel) sit beside speciality brands (Circa, theScore Bet). Regulators and stakeholders will watch early handle, promotional spend and whether Missouri meets revenue forecasts as the market matures.
