Prediction Markets Inch Closer to the Supreme Court

The fight over whether the CFTC or individual states control prediction markets is escalating across multiple courtrooms, and legal analysts now say the question of federal preemption over event contracts appears headed for the U.S. Supreme Court. No petition has yet been confirmed at the high court, but the litigation map already spans a half-dozen states.

The clearest marker came on April 28, 2026, when the Commodity Futures Trading Commission announced a lawsuit against Wisconsin, responding to state actions targeting Kalshi, Polymarket, Crypto.com, Robinhood and Coinbase, according to the agency’s own announcement. In that filing the CFTC asserted exclusive federal jurisdiction over event contracts traded on designated contract markets, a litigating position rather than a settled judicial ruling.

How prediction markets could reach the Supreme Court

The same CFTC announcement disclosed that the agency had also sued Connecticut, Illinois and New York, and had filed amicus briefs in the Ninth Circuit and the Massachusetts Supreme Judicial Court. That geographic spread, across trial courts and appellate venues, is what gives the dispute a plausible path upward.

Katten Muchin Rosenman attorneys reported that the CFTC and the Department of Justice sued New York in the Southern District of New York, seeking declaratory relief and a permanent injunction against state enforcement of gambling laws the government argues are preempted, per their published analysis. That same analysis identifies Commonwealth of Massachusetts v. KalshiEx LLC, No. SJC-13906, where the CFTC argues that sports event contracts are swaps and that the Commodity Exchange Act preempts state gambling laws for swaps traded on designated contract markets.

Prediction markets let users trade contracts that pay out based on the outcome of a defined event, and the specific products at issue here include sports-outcome contracts. Related procedural fights are already surfacing elsewhere, including a request that the Supreme Court rule on state regulation of sports event contracts in New Jersey.

Reaching the high court is not automatic. Supreme Court Rule 10 states that certiorari review is discretionary and granted only for compelling reasons, and Rule 10(a) treats conflicting decisions among federal courts of appeals on the same important question as a factor supporting review, as laid out in the rule’s text. A predicted appeal is not an accepted case, and the current record does not establish a confirmed circuit split or a docketed petition.

Which regulatory questions could shape the dispute?

The core legal question is whether the Commodity Exchange Act and CFTC oversight preempt state gambling laws for event contracts traded on designated contract markets. The CFTC’s position, stated in its Wisconsin announcement, is that federal jurisdiction over these contracts is exclusive.

The competing interpretations pit federal market authority against state gambling regulation. In the Massachusetts matter, the CFTC’s argument that sports event contracts qualify as swaps is central, because swap status is what triggers the preemption theory. These remain arguments advanced by the government, not judicial holdings, and any eventual ruling would be bounded by the specific parties, products and jurisdictions before each court. The parallel CME dispute over Kalshi’s Bitcoin perpetual futures underscores how contested the boundaries of CFTC authority have become.

What the uncertainty means for prediction-market users

For now, the dispute is unresolved and no nationwide ruling settles whether these contracts may be offered where states object. The Katten analysts wrote that the nationwide litigation over CFTC jurisdiction shows no signs of abating and appears destined for consideration by the Supreme Court, a forecast rather than confirmation of any filing or grant.

The next verifiable milestone would be an actual certiorari petition or a grant of review, neither of which is established in the current record. Until a court of appeals conflict is confirmed and a petition is docketed, the path to the Supreme Court remains a projection built on a widening set of trial-court and appellate cases.
