Thirty-eight state attorneys general join legal fight against Kalshi event contracts
Thirty-eight state attorneys general have joined litigation against Kalshi over its event contracts. New York's attorney general argues that Kalshi's CFTC registration does not matter because the state classifies the contracts as wagers. Kalshi contends the products are financial derivatives comparable to futures contracts and therefore fall outside state gambling laws. Michigan Attorney General Dana Nessel sued Kalshi in March, and that case now intersects with a broader CFTC rulemaking push on event contract oversight. The New York case has taken on a partisan dimension according to the Times Union.
Kalshi's CFTC registration was supposed to provide a single federal standard, but it is now being tested in dozens of state courts simultaneously. New York and Michigan explicitly reject that registration as a shield against state gambling law. Each additional state that files forces Kalshi to either geofence that market or risk contract voiding and enforcement penalties there.
Traders now face geography-dependent validity, where a contract legal under federal rules may be worthless depending on the state. The platform must manage parallel litigation costs and operational complexity across multiple fronts while waiting for a national standard. The Second Circuit appeal is the only path to resolve this split, but more states may act before that court rules. Federal registration is increasingly a label that does not block state enforcement.
