Sixth Circuit preemption loss leaves Arkansas exposed in federal court

Tim Griffin filed his lawsuit against Kalshi on November 4 in the Circuit Court of Independence County. Within weeks, he had the DOJ and the CFTC standing across from him in federal court.

That sequence matters. Griffin's complaint was a state attorney general doing what state attorneys general do — asserting that a company operating inside Arkansas borders, taking money from Arkansas residents, without an Arkansas license, is running an illegal gambling operation. The Arkansas Deceptive Trade Practices Act gives him that argument. What he may not have weighted correctly is how hard the federal government would move to cut it off.

The CFTC's 34-page complaint argues that event contracts are swaps under the Commodity Exchange Act, that Kalshi is a CFTC-designated contract market, and that Arkansas trying to shut down a federally regulated exchange intrudes on a congressional scheme that was designed to be exclusive. The DOJ filed alongside them. That is not a friend-of-the-court letter — that is the federal government asserting that Griffin is in the wrong jurisdiction before he has had a hearing.

CFTC Chairman Michael Selig framed it as a defense of market infrastructure: event contracts provide "valuable information about the future" and the agency will not allow state interference to "destroy federally regulated markets." That language is worth reading carefully. Selig is not just defending Kalshi. He is building the record for every preemption fight that follows.

Here is where I would push back on the consensus read. Most of the analysis around this case treats federal preemption as the strong hand. The mechanism is correct. The CEA preemption argument is real, it has survived multiple federal courts, and having the DOJ co-sign it strengthens the position considerably. But the Sixth Circuit ruling that came out of the North Carolina and Georgia litigation has already shown that preemption is not automatic — courts are willing to look closely at whether a specific contract type falls within the CEA's scope. Griffin's argument is not that the CFTC lacks jurisdiction over swaps. His argument is that what Kalshi is offering Arkansas residents is not a swap. It is a bet. That framing has moved courts before.

I mispriced a regulatory outcome in early 2025 by overweighting the structural argument and underweighting political timing. I recalibrated toward treating political actors as inputs with their own logic, not noise around a correct mechanism. Griffin is not making a legal error when he files in state court. He is making a political calculation — that enough state-level pressure, sustained across enough jurisdictions, forces a congressional renegotiation of the CEA's scope regardless of how individual preemption cases resolve.

The CFTC's self-certification investigation into Kalshi is running in parallel. If that inquiry finds that Kalshi submitted contracts without proper notification, Griffin gets a new line in his brief: the federal regulator itself found compliance failures. The preemption argument requires the federally regulated exchange to have been operating lawfully. That condition is not currently settled.
