Missouri Joins the Expanding U.S. Sports Betting Landscape
On December 1, 2025, Missouri became the 39th state to legalize sports betting, marking a significant step in the rapid growth of the industry across the United States. Industry experts anticipate that Missouri will see between $3.5 billion and $4 billion in wagers during its inaugural year, fueled by aggressive marketing campaigns from leading operators such as DraftKings, Caesars Sportsbook, and FanDuel.
The regulatory framework, established through the voter-approved Amendment 2 in 2024, permits up to 14 online betting licenses. Notably, two of these licenses are "untethered," allowing companies like DraftKings and Circa Sports to operate independently, without the need for partnerships with local casinos or sports teams.
National Trends and the Rise of Proposition Bets
Since the Supreme Court lifted the federal ban on sports betting in 2018, the industry has experienced explosive growth. In the first nine months of 2025 alone, revenues reached $11 billion—a 13% increase compared to the previous year, according to the American Gaming Association.
However, the increasing popularity of proposition bets—wagers placed on specific in-game events, such as individual player performances—has sparked debate over ethical and regulatory concerns. Missouri's legislation bans prop bets on college athletes within the state, aiming to protect the integrity of local collegiate sports. Despite this, critics argue that such measures are insufficient in an era where bettors can easily access unregulated online platforms.
Concerns Over Integrity and Scandals
Yale University marketing professor Nathan Novemsky likened Missouri's restrictions to "a Band-Aid on a dam that's breaking," emphasizing that the state's limited approach does not fully address the risks associated with prop betting. Recent controversies, including allegations of Major League Baseball pitchers accepting bribes to influence game outcomes and an NBA player facing charges for sharing insider information, have heightened concerns about corruption linked to micro-betting.
In response, organizations like Major League Baseball have implemented new safeguards, such as capping individual pitch bets at $200 and excluding them from parlay wagers, in an effort to reduce the potential for manipulation.
Regulatory Challenges and Market Expansion
Missouri's regulatory system seeks to balance fostering a competitive betting market with minimizing risks. The state's Gaming Commission, staffed by just three regulators, relies heavily on betting operators to identify and prevent fraudulent activity. Meanwhile, other states—including Nebraska, Oklahoma, and Georgia—are considering similar legislation, and analysts predict that all 50 states could legalize sports betting within the next five years. The emergence of prediction market platforms like Polymarket and Kalshi is also contributing to the industry's expansion, offering alternative options in states where traditional sports betting remains illegal.
Operator Strategies and Responsible Gambling
For companies entering Missouri, the stakes are high. DraftKings, for example, launched with a promotional offer allowing users to bet $5 for a chance to win $300, leveraging its untethered license to quickly build a customer base. Such aggressive promotions are common as operators compete for market share, especially during peak sports seasons. However, the growing prevalence of prop bets and parlays—where multiple bets are combined—has raised alarms about the potential for increased problem gambling. Missouri has allocated $5 million annually to support problem gambling initiatives, but experts question whether this funding will be sufficient as the market continues to expand.
The Road Ahead for U.S. Sports Betting
The future of sports betting in America will depend on how well the industry can balance rapid growth with the need for ethical oversight and effective regulation. Missouri's entry into the market highlights both the opportunities and the challenges ahead. As more states consider legalization, the ongoing debate over innovation versus integrity will play a crucial role in shaping the next chapter of this evolving industry.
