Federal Wrangling Over Prediction Markets: New York Joins the Fray

by

In a turn of events most diverting, the Commodity Futures Trading Commission has taken up its quill to sue the state of New York, objecting most strenuously to the enforcement of its gambling laws upon federally registered prediction market exchanges.

The complaint, filed with great solemnity in the Southern District of New York, seeks a declaratory judgment-a matter of no small importance-confirming federal preemption, alongside a permanent injunction to stay the hand of the state against CFTC-registered designated contract markets. One can only imagine the flurry of papers and the gravity of the situation.

New York Joins the Unfashionable Quartet

New York now finds itself in the company of Arizona, Connecticut, and Illinois, states already acquainted with the CFTC’s determined advances. The agency, with a zeal most remarkable, sued these three earlier in the month over their parallel enforcement campaigns against registered prediction market venues. One might say they are quite the persistent suitors.

A federal judge in Arizona, with a swiftness that would put even the most eager matchmaker to shame, granted the agency a temporary restraining order, halting that state’s criminal case against CFTC-regulated platforms. The CFTC, not content with this victory, has also filed an amicus brief in the Ninth Circuit Court of Appeals, defending its preemption argument with a vigor that would make even the most ardent advocate blush.

New York is the latest state to ignore federal law and decades of precedent by seeking to enforce state gambling laws against @CFTC-registered derivatives exchanges. Today’s lawsuit builds upon the @CFTC’s ongoing efforts in other states to protect its exclusive jurisdiction over…

Massachusetts Enters the Parlour

On the very same day, the agency filed an amicus brief in the Massachusetts Supreme Judicial Court in the case of Commonwealth of Massachusetts v. KalshiEx LLC. Attorney General Andrea Campbell, with a determination most formidable, had previously secured a preliminary injunction blocking Kalshi from offering sports event contracts to Massachusetts customers. One wonders if the courts will find her arguments as compelling as she does.

The brief, with a gravity befitting the occasion, argues that the Commodity Exchange Act preempts state laws applied to CFTC-regulated markets. Chairman Selig, with a confidence most striking, declared that Congress had assigned the agency sole authority over commodity derivatives, prediction markets included. One can only hope the courts will see the matter in the same light.

Kalshi, not to be outdone, recently prevailed at the Third Circuit Court of Appeals in a parallel New Jersey case, a victory that has no doubt strengthened the federal preemption argument. Kalshi and Polymarket, between them, face more than a dozen state and tribal challenges over sports and political event contracts. It seems they are quite the popular pair, though not in the most flattering of ways.

Prediction Markets: The Newest Fad in Town

Trading activity on both platforms has climbed most remarkably through early 2026, with sports event contracts emerging as the central flashpoint between state and federal authorities. Google Finance, ever the trendsetter, has integrated Kalshi and Polymarket odds data, pulling prediction market pricing further into mainstream financial coverage. One can only imagine the gossip this will inspire in the drawing rooms of high finance.

Federal courts in New York and Massachusetts will now rule on whether the Exchange Act blocks state gambling claims. Their decisions, alongside the CFTC’s Ninth Circuit amicus and the Arizona restraining order, could shape national rules for a fast-growing industry that operates across every state. One can only await the outcome with bated breath, and perhaps a touch of amusement at the spectacle of it all.
