Key Takeaways
- Wisconsin faces a federal lawsuit from the CFTC, marking the agency’s fifth state legal action regarding prediction market oversight.
- State prosecutors targeted Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase, alleging unlicensed gaming activities.
- CFTC Chairman Michael Selig maintains federal law grants the agency sole authority over event contracts in prediction markets.
- New York, Arizona, Connecticut, and Illinois have received similar federal challenges from the CFTC during the same period.
- An Arizona court has temporarily halted criminal proceedings against Kalshi, indicating possible federal law supremacy over state gaming regulations.
Federal commodities regulators initiated legal proceedings against Wisconsin this Tuesday following state action against five platforms operating prediction markets. The agency contends state regulatory frameworks hold no jurisdiction in this matter.
State authorities filed their complaint last Thursday targeting Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase. Wisconsin prosecutors characterized sports-related event contracts on prediction markets as unauthorized wagering under state gaming statutes.
The federal response arrived swiftly. The CFTC, working alongside the Justice Department’s Civil Division, submitted its complaint to the U.S. District Court for the Eastern District of Wisconsin.
This marks the agency’s fifth state-level legal challenge in recent weeks. Previous filings targeted New York, Arizona, Connecticut, and Illinois.
CFTC Chairman Michael Selig leads this coordinated effort. He currently serves as the only sitting member of the commission, which typically comprises five positions.
Selig issued a statement declaring: “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.”
Federal regulators classify prediction markets as derivative instruments. The agency maintains these contracts qualify as designated contract markets under federal supervision rather than state gaming frameworks.
Jurisdictional Conflict Between Governments
The central question revolves around which level of government holds regulatory power over prediction market operations. Federal commodities regulators claim Congress delegated exclusive oversight authority to their agency for these contract types.
State officials counter this interpretation. Their position holds that sports-based event contracts represent gambling products requiring state gaming authorization. Multiple states have initiated both civil lawsuits and criminal prosecutions against platform operators.
Arizona courts recently suspended criminal proceedings against Kalshi. The presiding judge indicated federal regulators appear positioned to demonstrate federal law preemption over state gambling statutes.
Federal Agency Relief Requests
The Wisconsin complaint identifies Governor Anthony Evers, Attorney General Josh Kaul, and the Wisconsin Gaming Division as defendants.
Federal regulators request judicial determination that state gambling statutes lack applicability to federally supervised prediction markets. The agency additionally seeks permanent injunctive relief preventing Wisconsin from pursuing enforcement actions against these platforms.
Coinbase and Robinhood, both operating as publicly traded corporations, appear among the platforms named in Wisconsin’s state complaint. Gemini received naming in New York’s distinct legal action against Coinbase.
New York authorities filed suit against Coinbase and Gemini last week concerning their prediction market services. The CFTC countered with its own lawsuit against New York within days.
The Wisconsin Department of Justice, the Division of Gaming, and Governor Evers’ office had provided no public statements regarding the litigation at publication time.
