Missouri sports betting operators reported significant momentum after the first full week of legal wagering, with active accounts more than doubling and NFL betting leading statewide activity.
Key Takeaways
- Active sports betting accounts in Missouri more than doubled to 520,000 in the first full week of wagering.
- Operators reported high engagement with NFL betting, prop markets, and marquee matchups featuring the Kansas City Chiefs.
- Missouri bettors recorded several notable wins across DraftKings, Caesars, and Circa during week one.
GeoComply data showed that over 520,000 betting accounts were in use as of Dec. 8, a sharp increase from the 250,000 recorded the previous week. Operators said early trends reflected strong interest in professional football, parlay bets, and player-specific props.
Of the available operators currently in Missouri, DraftKings highlighted a nine-leg NBA parlay as its most profitable long-shot wager of the week, turning a $1 stake into $1,929.70. The company said early activity aligned with expectations, noting that the Kansas City Chiefs quickly became the most-bet team in the Show-Me State.
Caesars Sportsbook also reported strong Chiefs engagement around Sunday Night Football, though its most-bet prop involved Detroit Lions running back Jahmyr Gibbs, who scored multiple touchdowns against the Dallas Cowboys.
Caesars' largest win in Missouri came from a bettor who secured $26,529.35 after taking Michigan State's live money line against undefeated Iowa in men's college basketball.
Circa said betting volume grew steadily through the week, with particular interest in Chiefs–Texans markets and props tied to Travis Kelce and Patrick Mahomes.
With over 10,000 active accounts in and around Arrowhead Stadium and more than 43,000 geolocation checks during the game, GeoComply data further demonstrated the game-day demand.

Mobile wagering raises public health concerns
The increase in betting activity has raised broader concerns about how mobile wagering will impact Missouri's social and financial landscape. State officials anticipate that legalized online betting will generate hundreds of millions of dollars in new revenue.
The state will also begin to capture spending that previously flowed to neighboring Illinois and Kansas. However, addiction specialists warned that the same accessibility driving record participation could also accelerate high-risk gambling behaviors.
Mental health professionals noted that the law allows a wide range of wagers. Specialists view these markets as particularly risky because they encourage rapid, repetitive betting.
The state's one major restriction, a ban on wagering involving Missouri colleges and universities, was included to address integrity concerns and satisfy the Sports Betting Alliance.
Aaron Laxton of the Assisted Recovery Centers of America (ARCA) said problem gambling currently affects an estimated 2% of Missourians but could rise as high as 10% as mobile betting becomes routine. He explained that treatment providers already see individuals hiding losses, withdrawing socially, and facing escalating financial strain.
To address the expected increase in gambling-related harm, Missouri established a $5 million compulsive gambling fund to support treatment and prevention initiatives. Laxton said sportsbook apps include voluntary safeguards, such as spending limits and self-exclusion tools, but warned that early wins can reinforce addictive patterns.
ARCA and similar organizations are preparing for higher demand for services, including support for co-occurring issues such as alcoholism, as the state adjusts to expanded access.
