Missouri sports betting officially began statewide today, December 1, 2025, opening both mobile and retail wagering after years of legislative debate and a narrow ballot approval. The new framework allows adults 21 and older, physically located within the state, to place bets via licensed mobile apps or at approved casino and retail sportsbook locations.
The Missouri Gaming Commission completed a regulatory roll-out in the months ahead of launch to vet operators and finalize compliance rules. On launch day, multiple national operators initiated services in the state, offering mobile apps and retail counters at casinos across the state. The law authorizes wagers on professional sporting events, approved college competitions, and international fixtures, while prohibiting bets tied to individual performances by athletes on in-state college teams and restricting youth sports wagering.
Betting options include live, pregame and parlay markets, along with same-game parlays and multi-leg bet builders. Missouri sports betting revenue will be taxed at a flat rate of 10 percent on adjusted gross revenue. Lawmakers allocated a portion of receipts to education and created a fund for problem gambling prevention and treatment services.
The regulatory package requires strict age verification, geolocation checks to ensure bets are placed inside state lines, secure payment controls, and player protections such as self-exclusion tools. A statewide hotline and treatment resources have been put in place to support those affected by gambling harm.
Proponents say Missouri sports betting will move wagering from unregulated channels into a transparent system, generate new public revenue, and provide legal options for fans who previously traveled out of state to place bets.
Opponents warn of social harms tied to expanded gambling access. State officials say the law’s consumer protections and earmarked funding are designed to mitigate those risks. With Missouri sports betting now active, operators and local communities will watch early revenue and participation closely to assess economic impacts and whether the intended safeguards are working.
