CFTC Sues Illinois, Arizona & Connecticut to Defend Prediction Markets
On April 2, 2026, the CFTC and DOJ filed three separate federal lawsuits seeking to pre-empt state gambling laws being used to restrict CFTC-licensed prediction market exchanges. Here's what that means for traders right now.
Why Is the CFTC Suing States?
Prediction markets like Kalshi and Polymarket are federally regulated by the CFTC as Designated Contract Markets (DCMs). Despite this federal license, several states have argued that prediction market contracts constitute illegal gambling under state law — and have taken steps to restrict or block access for residents.
The CFTC's position: federal law preempts state gambling statutes when it comes to CFTC-regulated contracts. The lawsuits filed April 2, 2026 seek declaratory judgments in federal district courts establishing that CFTC-licensed prediction markets cannot be blocked by state gambling enforcement.
Four days after those suits were filed, the CFTC's core legal theory received its first federal appeals-court validation. On April 6, 2026, the Third Circuit ruled 2-1 in KalshiEX LLC v. Flaherty that the CFTC has exclusive jurisdiction over trades on DCMs, strengthening the agency's hand in its new cases against Arizona, Connecticut, and Illinois.
This follows Kalshi's 2024 federal court victory over the CFTC itself — a case that established prediction market election contracts as legally permissible. The new suits extend that logic to the states.
