Missouri sports betting opened with heavy traffic and high wager volume, but early tax returns remained modest as operators leaned hard on promotions during the launch phase.
Good to Know
Missouri first full month of legal sports betting produced immediate volume. State regulators reported just over $543 million in wagers during December, marking the debut month after the market officially launched on December 1, 2025.
Despite the half billion dollar handle, tax collections stayed limited. Missouri received about $521,200 in sports betting tax revenue for the month. Promotional credits played a major role in suppressing taxable income, even as sportsbooks posted strong top line activity.
Gross revenue across all sportsbooks reached roughly $104 million. However, aggressive sign up bonuses and promotional wagering deductions pushed online operators to report an adjusted loss of $21.6 million. That result stood in sharp contrast to retail sportsbooks, which reported about $887,000 in revenue.
Promotions shaped the entire opening month. Several operators offered low risk or no loss style bets designed to attract customers quickly, including wagers tied to basic outcomes such as whether a game would include at least one point scored.
The market quickly consolidated around familiar national brands. FanDuel and DraftKings accounted for more than $400 million of all wagers placed in the state. Because both operators reported negative adjusted revenue, neither owed sports betting tax for December.
FanDuel led the market with about $212 million in handle, narrowly ahead of DraftKings at $195 million. Before promotions, FanDuel reported nearly $46 million in revenue, compared with $31.6 million for DraftKings. Together, the two books controlled more than 75 percent of all Missouri betting activity, a share consistent with results seen in other states.
Behind the market leaders, bet365 ranked third in handle and gross revenue. BetMGM placed fourth in handle but slipped to sixth in revenue. Fanatics finished fifth in handle and fourth in revenue, just ahead of Caesars. theScore Bet ranked seventh, followed by Circa in eighth.
Football drove the largest share of betting volume. Wagers on football totaled just under $150 million, while basketball followed at slightly more than $98 million. Parlays proved especially popular, generating about $213 million in handle and ranking as the most bet category overall.
Early engagement metrics also stood out. According to GeoComply, more than 2.6 million sportsbook login attempts occurred on launch day alone. Those attempts came from over 250,000 active accounts.
Activity remained elevated throughout the opening week. GeoComply recorded more than 18.5 million login attempts during Missouri first week of legal betting, tied to more than 520,000 unique accounts.
Looking ahead, Missouri is projected to generate around $4 billion in handle during the first full year of legal sports betting, based on a Covers analysis. Using an industry average hold near 10 percent, that level of wagering would translate to about $400 million in operator revenue.
December results follow a common launch pattern. Early months tend to show inflated handle paired with weaker revenue as sportsbooks prioritize customer acquisition. NFL regular season months such as September through December are expected to remain among the strongest periods for wagering volume in Missouri.
The initial revenue report also marked the end of a long rollout. Missouri voters narrowly approved legal sports betting through a constitutional amendment in November 2024. Regulatory delays followed, pushing the launch to December 1, 2025, the latest date allowed under the ballot language.
