In a dramatic escalation of the conflict over the oversight of prediction markets, the Commodity Futures Trading Commission (CFTC) has filed federal lawsuits against Arizona, Connecticut, and Illinois.
The legal challenge names the governors and attorneys general of these states as defendants, accusing them of overstepping federal authority granted by the Commodity Exchange Act.
Defending Exclusive Federal Authority
The CFTC argues that prediction markets, which offer “event contracts” on sports and political outcomes, fall under its exclusive jurisdiction as financial derivatives, not state-level gambling. CFTC Chair Michael Selig took to social media to criticize the states for creating a “fragmented patchwork” of regulations that destabilizes market participants.
“Despite the CFTC’s clear and longstanding exclusive jurisdiction to regulate event contracts… various states have attempted to outlaw, regulate, or otherwise restrain the activities of DCMs that facilitate trading in lawful event contracts. Congress long ago decided that a national framework for commodity derivatives markets was preferable,” stated a CFTC release.
Market Uncertainty and “Overzealous” Enforcement
The lawsuits follow cease-and-desist orders issued by the three states against platforms like Kalshi and Polymarket. Arizona went as far as filing criminal charges against Kalshi, a move Selig described as “aggressive and overzealous.”
Selig warned that such state-level actions risk “destabilizing effects” for market participants:
“This is not the first time states have tried to impose inconsistent and contrary obligations… but Congress specifically rejected such a fragmented patchwork because it resulted in poorer consumer protection and increased risk of fraud and manipulation”.
By suing these states directly, the CFTC is making a definitive stand to protect its regulatory perimeter, a move that will likely result in a landmark Supreme Court decision regarding the boundary between finance and gambling.
