The Commodity Futures Trading Commission has initiated a legal campaign asserting its exclusive authority over derivatives markets, with Chair Michael Selig pledging to pursue the matter to the Supreme Court if needed.
On October 30, 2026, Selig stated the agency is "prepared to fight these challenges all the way up to the Supreme Court." The comment reflects an escalating dispute between federal regulators and state governments over prediction markets and event contracts—products that allow trading on real-world outcomes.
The Dispute
The CFTC has filed lawsuits against at least 10 states, including Arizona, Connecticut, Illinois, and Utah. The first cases were filed in April 2026, with the number reaching 10 by late October.
States have increasingly classified prediction market products as gambling, pursuing enforcement actions and legislation to restrict them. The CFTC contends that when these contracts trade on federally registered exchanges, federal authority supersedes state jurisdiction.
Legal Foundation
The agency bases its position on the Commodity Exchange Act, specifically 7 U.S.C. § 2(a)(1)(A), arguing the statute grants exclusive CFTC jurisdiction over swaps and futures on designated contract markets. The CFTC maintains that federal preemption should override conflicting state regulations targeting these venues.
Beyond its own litigation, the CFTC has filed amicus briefs in four federal appeals courts and one state supreme court as of late October 2026.
Early Outcomes
Initial rulings have favored the CFTC. Preliminary injunctions supporting the agency were granted in cases from Arizona and Illinois. The platforms involved in the litigation include Kalshi, Polymarket, and Crypto.com/Nadex.
Broader Implications
A national regulatory framework would allow platforms to operate under consistent rules. A CFTC loss could require them to comply with varying restrictions across each objecting state. The outcome will also clarify whether federal oversight of event contracts is as broad as the agency claims or whether states retain regulatory authority in this space.
