Missouri sports betting — voter-approved in 2022, launched 2023
Missouri took a longer path to sports betting than most states: it required a voter referendum. Voters approved Amendment 2 in November 2022 with approximately 54% in favor, authorizing online and retail sports wagering. The Missouri Gaming Commission oversaw licensing, with FanDuel, DraftKings, BetMGM, and other major operators launching in 2023. Missouri has the Cardinals and Blues (NHL), Chiefs (NFL, Kansas City), Royals (MLB), and strong college sports markets (Mizzou, Missouri State).
CFTC-regulated prediction markets operate in parallel with Missouri's licensed sportsbooks. The Missouri Gaming Commission oversees sports betting; Kalshi operates under CFTC federal jurisdiction: the same separation seen in every other open state, with no friction between the two frameworks.
MO traders have full flexibility: FanDuel/DraftKings for NFL (Chiefs), Cardinals spreads, props, and parlays; Kalshi for binary outcome contracts, Fed rate markets, and political event contracts. No regulatory friction between the two in Missouri.
Missouri income tax on prediction market winnings
Missouri has a graduated income tax structure with a top rate of 4.8% on income above $9,072. Most prediction market traders with any meaningful income will be at or near the 4.8% rate. Prediction market winnings are ordinary income.
Missouri's 4.8% top rate is lower than Illinois (4.95%), competitive with Kansas (5.7%), and higher than Indiana (3.05%). Kansas City residents who work in Kansas or Missouri may have cross-state tax considerations.
Kalshi issues a 1099-MISC for net profits. Report on your Missouri state return (Form MO-1040) as ordinary income. Sports betting losses are subject to the 2026 OBBBA 90% cap; Kalshi prediction market losses are not (commodity derivatives, not sports wagers).
