CFTC proposes rule to draw federal gambling-gaming line for prediction markets
The CFTC has proposed rulemaking that would formally define how the distinction between gambling and gaming applies to prediction markets, a determination with major consequences for how event contracts are classified and overseen. The proposal deepens an emerging conflict between federal regulators and states, coming as the agency simultaneously sues Rhode Island and Minnesota to block state-level enforcement actions against prediction market platforms. Sports wagers account for the majority of activity on Kalshi and a significant share on Polymarket, making the definitional question particularly consequential for those operators' core offerings.
Kalshi and Polymarket must now map every sports contract against this definitional standard while also responding to two other open CFTC rulemakings. A final rule reclassifying any current market as gambling would trigger immediate delisting and expose both platforms to enforcement if they haven't exited within the review window.
The gambling-versus-gaming definitional fight joins three simultaneous CFTC rulemakings now open for comment, each with different deadlines and public-interest standards that platforms must separately satisfy or risk mandatory delisting.
