CFTC v. Wisconsin
Case Overview
The CFTC sued Wisconsin over a state measure authorizing prediction market contracts, asserting federal preemption under the Commodity Exchange Act. The case is a companion to CFTC v. Arizona, part of the CFTC's enforcement campaign against state-level prediction market authorization.
The Facts
Wisconsin enacted or proposed legislation permitting prediction market activity within the state, challenging the CFTC's exclusive jurisdiction. The CFTC filed a preemption suit in the Western District of Wisconsin, arguing that state authorization of such contracts conflicts with federal commodity law.
The Application
Wisconsin's authorization of prediction market contracts directly conflicts with the CFTC's exclusive jurisdiction over commodity derivatives established by the Commodity Exchange Act. By enacting state legislation to permit what federal law reserves exclusively for federal regulation, Wisconsin attempted to regulate financial instruments that the CEA places solely within the CFTC's purview. The preemption doctrine requires that federal law—which clearly vests all commodity derivatives oversight in the CFTC—displaces any state law purporting to create a parallel regulatory scheme. As a result, Wisconsin's prediction market authorization cannot stand as a matter of federal preemption.
The Conclusion
Active 2026 litigation, companion to CFTC v. Arizona. Both cases will shape the regulatory framework for state prediction market laws.
