The US Commodity Futures Trading Commission sued Wisconsin on April 29, 2026, asserting exclusive federal jurisdiction over prediction markets after the state sued five CFTC-regulated platforms. The lawsuit marks the fifth state-level enforcement action by the CFTC this month, escalating a jurisdictional conflict between federal and state regulators over who controls event contracts. Wisconsin had sued Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase on April 24, claiming their prediction market platforms violated state gambling laws.
Wisconsin’s Challenge to Federal Authority
Wisconsin argued that sports-related event contracts offered by the five platforms constitute illegal betting under state law and require gaming licenses issued by state authorities. The state’s Gaming Division, led by administrator John Dillett, contended that prediction markets fall under state gambling jurisdiction. Governor Anthony Evers and Attorney General Josh Kaul were named as defendants in the CFTC complaint. The federal regulator countered that prediction markets are designated contract markets under exclusive federal oversight, not state-regulated gambling instruments.
Rapid Escalation Across Five States
The CFTC filed its Wisconsin complaint with the Justice Department’s Civil Division, seeking a declaration of exclusive federal jurisdiction and a permanent injunction blocking state enforcement. This marks the agency’s fifth lawsuit against a US state in April 2026 alone. The CFTC previously sued Arizona, Connecticut, Illinois, and New York during the same period. CFTC Chairman Michael Selig stated: “States cannot circumvent the clear directive of Congress. Our message to Wisconsin is the same as to New York, Arizona, and others: if you interfere with the operation of federal law in regulating financial markets, we will sue you.” The complaint asserts that Wisconsin’s enforcement “intrudes on the exclusive federal scheme Congress designed to oversee national swaps markets.”
Federal vs. State Control of Event Contracts
The dispute centers on whether prediction market contracts fall under federal Commodity Futures Trading Commission authority or state gambling statutes. The CFTC’s position is that designated contract markets—platforms regulated under federal law—cannot be subject to conflicting state gaming requirements. This interpretation directly challenges state-level gambling enforcement as applied to prediction markets. The rapid filing of five lawsuits suggests the CFTC is pursuing a coordinated strategy to establish federal primacy. Selig’s remarks at Bitcoin 2026 in Las Vegas on April 28 preceded the Wisconsin filing by one day, signaling advance preparation for the enforcement push.
Unresolved Path Forward
The outcome of the Wisconsin case remains uncertain, with no timeline disclosed for resolution. The platforms named in Wisconsin’s initial lawsuit—all major US crypto and trading firms—face conflicting regulatory demands. Resolution will likely depend on federal court interpretation of Congressional intent regarding prediction market regulation. Wisconsin officials have not publicly responded to the CFTC’s claims. The coordinated litigation strategy suggests the CFTC is consolidating federal authority before additional states act.
