Prediction Markets
in Colorado
Colorado is a prediction market-friendly state: all major platforms are available with no enforcement actions. Colorado is also one of the first states to have legalized sports betting (2020), which provides important context: the Colorado Limited Gaming Control Commission has regulated traditional sports betting without creating regulatory friction for CFTC-regulated prediction market platforms. Colorado has a 4.4% flat state income tax rate.

Colorado: legal sports betting coexists with prediction markets
Colorado voters approved sports betting by ballot initiative in November 2019 (Proposition DD), and licensed sportsbooks launched in May 2020. Colorado has since become a reference case for how CFTC-regulated prediction markets coexist with state-licensed sportsbooks: both operate simultaneously without regulatory conflict.
The Colorado Division of Gaming regulates traditional sports betting under state law. Kalshi's prediction market contracts fall under CFTC federal jurisdiction: a separate regulatory lane. The Colorado Division of Gaming has not asserted authority over federally-regulated prediction market exchanges, and no Colorado AG action has targeted Kalshi or Polymarket.
Colorado traders can use both: FanDuel/DraftKings for spread and parlay sports betting; Kalshi for binary event contracts on sports outcomes, plus economics, politics, and weather. No regulatory conflict between the two frameworks in Colorado.
Colorado state income tax on prediction market winnings
Colorado has a flat 4.4% state income tax rate. Prediction market winnings are ordinary income taxed at this rate. Simple calculation: no graduated brackets to navigate.
Colorado's sports betting tax is 10% on gross revenue (the operator pays this). Bettors pay ordinary income tax on winnings. Prediction market taxes are separate: reported via 1099-MISC.
Colorado taxpayers using both FanDuel (sportsbook) and Kalshi (prediction market) will have two separate income streams: W-2G from large sportsbook wins and a 1099-MISC from Kalshi. They are reported separately on state and federal returns. Note the 2026 OBBBA change: sports betting losses are now capped at 90% deductibility; Kalshi losses are not subject to this cap.
