Federal government backs Kalshi in Arkansas gambling lawsuit

Federal government sides with Kalshi as Arkansas gambling case goes to court

The Arkansas attorney general's office did not expect a federal countersuit. When Tim Griffin filed in Independence County circuit court on November 4, the argument looked straightforward: Kalshi was taking money from Arkansas residents on sports and political outcomes without a state license, without state taxes, and without age verification aligned to Arkansas gaming law. The state had seen this pattern before. It knew how to prosecute it.

What it had not fully modeled was the CFTC under Chairman Michael Selig treating Griffin's filing as an existential threat to federal jurisdiction, not a local enforcement action.

The 34-page federal complaint does not read like a defensive brief. It reads like a agency that has decided this is the case it wants to win on. The CFTC's argument is that event contracts are swaps under the Commodity Exchange Act, that Kalshi is a designated contract market operating under federal authorization, and that Arkansas has no more right to shut it down than a state attorney general has to prosecute a federally licensed bank for taking deposits. The DOJ's presence alongside the CFTC signals that this framing has cleared more than one desk in Washington.

The preemption claim is not new. Kalshi has run this argument in Louisiana, in New York, in every courtroom that will hear it. What is new is the federal government running it with them. That is a different kind of case.

I have watched regulatory agencies file in support of the entities they regulate before. It is not always the signal it appears to be. Sometimes it reflects genuine jurisdictional principle. Sometimes it reflects an agency that has become too close to the industry it oversees. I cannot tell you from the public record which dynamic is operating here, and I will not pretend I can. What I can tell you is that the CFTC's assertion of exclusive jurisdiction has now been tested in several federal courts and the results have not been uniformly favorable. The Sixth Circuit preemption ruling, which cut against Kalshi's position, is the kind of precedent that federal judges read before they rule.

Here is where I break from the consensus read: most of the coverage is treating the DOJ-CFTC filing as a strong hand. I think it is a necessary hand, played because the state-level pressure has reached a volume that the agency cannot absorb quietly. An agency that files a 34-page complaint to defend its own jurisdiction is an agency that is not entirely confident the jurisdiction will hold. Strength does not typically require that much paper.

The Louisiana restraining order, covering ten operators and running to a November 30 hearing, creates the pressure Griffin's filing alone could not. Two states, two simultaneous legal theaters, one federal agency stretched across both. The CFTC can file against Arkansas. It cannot file against every state that moves in the next six months, and several are watching Independence County circuit court to see what a state win actually looks like.

Kalshi's preemption argument is legally coherent. It may also be legally insufficient. The Commodity Exchange Act's exclusive jurisdiction language was written for derivatives markets, not for a product that a circuit court judge in Arkansas is going to look at and see a parlay card. The gap between what federal law says and what a state judge perceives is exactly where these cases get decided in ways that federal filings cannot prevent.

The prediction market most worth watching here does not have a clean resolution date yet. It resolves when the first federal appellate court rules on whether the CEA preempts state gambling enforcement against a CFTC-designated contract market — not in dicta, not in a district court order, but in a published circuit opinion. That ruling, whenever it comes, is the one that sets the price on everything downstream. The CFTC's filing in Arkansas moved that ruling closer. It did not determine the outcome.
