CFTC Sues Wisconsin Over Alleged Crypto Prediction Market Jurisdiction Clash

According to the CFTC, Wisconsin’s lawsuits against Coinbase, Robinhood, Crypto.com, Polymarket and Kalshi intrude on the agency’s exclusive authority over sports event prediction contracts.

Fact Check
Release Number 9220-26 and the filed complaint directly confirm that the CFTC sued Wisconsin on April 28, 2026 and that the dispute is about the agency's claimed exclusive federal jurisdiction over prediction markets/event contracts. The complaint expressly argues preemption under the Commodity Exchange Act and seeks to stop Wisconsin from applying state gambling laws to those markets. That matches the claim's core assertion of a federal-state jurisdiction clash. However, the wording 'crypto prediction markets' is somewhat narrower than the primary sources, which identify a mix of platforms and speak more broadly about prediction markets or event contracts rather than only crypto markets. CoinDesk's report aligns with the official sources.

Summary

The CFTC has sued Wisconsin officials in federal court after the state brought cases against Coinbase, Robinhood, Crypto.com, Polymarket and Kalshi over sports event contracts. The federal regulator argues that prediction markets fall under its exclusive jurisdiction, escalating a regulatory dispute over whether states can pursue enforcement against these products. The filing is the CFTC’s fifth similar lawsuit against a state in a month, highlighting a broader conflict between federal oversight of event-based derivatives and state-level action affecting crypto and prediction market platforms.
