Federal regulators have taken Wisconsin to court, turning up the heat in a widening fight over who gets to police the fast-growing world of prediction markets.
The Commodity Futures Trading Commission filed its lawsuit just days after Wisconsin launched its own civil cases against five companies: Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase. State officials accuse those platforms of running what amount to illegal sports betting operations, describing the alleged conduct as felony violations under Wisconsin law. All five companies operate in areas the Commodity Futures Trading Commission says fall squarely within its jurisdiction.
At the heart of the dispute are prediction markets, where people trade contracts tied to the outcome of real-world events. Congress handed the CFTC authority over many types of derivatives decades ago, and the agency says that mandate includes certain event-based contracts when platforms are registered as designated contract markets.
States like Wisconsin are taking a different approach. By treating these platforms as gambling operations, state regulators are trying to bring them under local law, setting up a direct collision with federal oversight.
States cannot circumvent the clear directive of Congress,” said Michael S. Selig. “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.”
Legal battle expands across multiple states
The Wisconsin case didn’t emerge in isolation. The CFTC recently filed a similar lawsuit against New York after that state pursued its own crackdown on prediction market platforms. The agency has also targeted Arizona, Connecticut and Illinois, while weighing in on related disputes through filings in higher courts, including the U.S. Court of Appeals for the Ninth Circuit and Massachusetts’ top court.
In some instances, the federal government is coordinating more broadly. The Department of Justice has joined the CFTC in backing arguments that federal law preempts state gambling statutes when it comes to regulated financial products. Those arguments could ultimately land before the U.S. Supreme Court as the number of cases grows.
What comes next for prediction markets
A recent ruling in Arizona shows how high the stakes have become. In a case brought by the CFTC, a federal judge issued a temporary restraining order that blocked a state criminal prosecution against a company overseen by the agency. The decision marked an early, but significant, victory for the federal position.
What happens in Wisconsin could shape the next phase of the fight. As prediction markets expand into new categories and attract more users, courts may have to draw clearer lines between financial regulation and gambling law. For now, the CFTC appears ready to press forward aggressively, signaling that this legal clash is far from over.
