Court rejects Kalshi's claim that CFTC registration blocks state gambling laws
A court rejected Kalshi's argument that its CFTC registration places its event contracts under exclusive federal jurisdiction. The ruling undermines the company's defense that state gambling laws cannot apply to its federally regulated contracts. Kalshi maintains its business model differs from sports betting and that its status as a designated contract market shields it from state oversight. The decision carries immediate precedential weight because courts in multiple states have now considered the same preemption question against the same CFTC-registered platform.
Kalshi's federal preemption shield is now pierced in another state, forcing the platform to fight market by market instead of in one clean federal case. This ruling invites parallel suits in additional jurisdictions, each multiplying legal spend and forcing geofencing decisions state by state.
The identical CFTC registration means Polymarket faces the identical exposure; every playbook tested on Kalshi previews its own defenses. For traders, contracts they understood as federally backed now face sudden voiding risk where state courts act. Kalshi's Second Circuit appeal carries the weight of restoring a single national standard, but that court may not rule before more states act.
Joins Michigan, New York, Washington, and Wisconsin as at least the fifth state court to reject or block Kalshi's federal preemption defense, leaving only Minnesota's narrow injunction breaking the pattern.
