Prediction market firms seek Supreme Court ruling on jurisdiction

IAGR and NAGRA ask Supreme Court to settle prediction market jurisdiction

Two gaming regulator associations filed a brief asking the Supreme Court to resolve whether federal commodities law prevents states from acting against sports event contracts on federally registered exchanges. The filing came from the International Association of Gaming Regulators and the North American Gaming Regulators Association, and it names the Kalshi cases as the source of the contradiction they want resolved.

The associations are not asking the Court to rule against prediction markets. They are asking it to rule at all. That is a different request, and it is the more interesting one.

The circuit split driving this has been building for months. A federal judge in Illinois concluded that Kalshi's sports contracts are likely swaps, which would place them under CFTC jurisdiction and beyond state reach. Ohio moved the other direction entirely, with regulators treating the same contracts as gambling products subject to state enforcement. Two jurisdictions, one product, two answers. The associations' argument is that the courts cannot keep producing contradictory answers without the Supreme Court drawing a line, and they are correct.

Here is where I part from the consensus read. Most of the commentary on this filing treats it as a win for Kalshi — another institutional voice asking for federal clarity, which tends to favor federal preemption. I don't think it lands that way. IAGR and NAGRA are gaming regulators. Their institutional interest is not in expanding federal jurisdiction over their domain. They want the Court to settle the question, but the question they are teeing up — whether commodities law prevents states from regulating these contracts — is one they almost certainly want answered with a "no." Regulatory associations do not typically file Supreme Court briefs to argue themselves out of authority.

The Illinois partial win for Kalshi, Coinbase, and the CFTC matters as a data point, but one district court's preliminary read on swap classification does not bind Ohio, does not bind New York, and does not bind the Ninth Circuit, where the Nevada argument is running on a different track. Kalshi is winning in some rooms and losing in others on the same week, which is precisely the posture that makes the Supreme Court brief intelligible. When outcomes diverge by jurisdiction, the underlying question is unresolved.

What the IAGR and NAGRA filing does is shift the procedural terrain. It signals to the Court that the ambiguity is not just costing Kalshi money — it is costing state regulators the ability to do their jobs, whichever way the answer runs. That framing is designed to make the Court feel the urgency of resolution rather than the luxury of waiting for the circuits to develop further. It is sophisticated. It may work. But the regulators filing it will have done the math on what resolution they expect, and their institutional history does not suggest they expect it to be preemption.
