Judge Rejects Kalshi’s Federal Preemption Claim in New York

A New York judge denied Kalshi’s request for an injunction and ruled that federal law does not preempt New York gambling statutes, clearing the way for state regulators to enforce state rules against the platform.

Kalshi operates an online exchange where users buy and sell contracts tied to the outcomes of events. The company argued those contracts fall under federal regulation of derivatives and related event contracts and sought a court order to bar state officials from applying New York gambling laws to its platform.

State authorities argued the contracts are subject to New York’s gambling prohibitions and that enforcement should proceed. The judge rejected Kalshi’s federal preemption argument, finding the federal statutes cited by the company do not clearly displace the state’s authority to regulate gambling in this area.

Under the ruling, Kalshi cannot rely on federal preemption to continue activities in New York that violate state gambling statutes. The company could alter its product offerings, pursue licensing or compliance with state requirements, or appeal the decision to a higher court.

Legal analysts noted that courts evaluate preemption claims by looking for clear congressional intent to override state law or a direct conflict that makes compliance with both laws impossible. The judge concluded neither condition was present in this case.

The decision establishes a New York precedent that state gambling statutes can apply to online event-contract platforms unless overturned by a higher court or federal legislation. Other states may reach similar results, leaving platforms subject to different state rules unless federal regulators or Congress set national standards.

The ruling does not resolve all questions about when event contracts fall under federal oversight. The case may proceed on appeal, and other courts could issue differing rulings.
