The U.S. Justice Department and Commodity Futures Trading Commission (CFTC) have sued Arkansas to stop its enforcement case against prediction-market operator Kalshi and prevent similar state action against other federally regulated exchanges.
The federal complaint, filed November 12 in the U.S. District Court for the Eastern District of Arkansas, names the state and Attorney General Tim Griffin as defendants. Federal lawyers argue that the Commodity Exchange Act gives the CFTC exclusive authority over derivatives traded on designated contract markets, including the event contracts targeted by Arkansas.
Federal lawsuit seeks protection beyond Kalshi
The government wants the court to declare that Arkansas cannot apply its gambling and consumer-protection laws to the disputed transactions on CFTC-regulated exchanges. Its request for preliminary and permanent injunctions covers investigations and enforcement against registered markets, their affiliates and business partners.
Kalshi is not a defendant in the new federal case. The complaint challenges Arkansas‘s attempt to proceed against the company through a separate state lawsuit filed eight days before. The federal agencies maintain that Kalshi’s event contracts qualify as swaps under the Commodity Exchange Act, placing their regulation within the CFTCs jurisdiction.
The government is relying on federal preemption, the principle that federal law can override state requirements when Congress has assigned an area of regulation to federal authorities. Arkansas, however, maintains that the activities at issue constitute gambling under its own laws. The judge has not yet ruled on the federal agencies request.
Gaming lawyer Daniel Wallach identified Arkansas as the eleventh state sued by the CFTC in disputes over prediction-market oversight. The previous cases include Arizona, Connecticut, Illinois, Kentucky, Minnesota, New Mexico, New York, Rhode Island, Utah and Wisconsin.

Separate federal challenges were already underway in Arkansas before the agencies filed their case. Polymarket US and OG.com, a prediction-market business associated with Crypto.com, both sued Griffin and state gaming officials on November 9. Those lawsuits seek to stop state restrictions on their federally regulated event contracts.
Arkansas alleges illegal gambling and deceptive practices
Griffin filed the original state complaint on November 4 in Independence County Circuit Court against KalshiEX LLC and Kalshi Inc. The case alleges that the platform offers unlicensed gambling involving sports, elections and entertainment while representing its activities as lawful financial trading.
“Arkansas law is concerned with substance, not semantics,” Griffin said in his November 4 statement.
He accused the company of accepting customers as young as 18, despite state rules governing licensed casino gambling, and avoiding licensing requirements, regulatory oversight and applicable taxes.
The 57-page complaint contains three claims under the Arkansas Deceptive Trade Practices Act and a separate unjust-enrichment claim. It alleges that Kalshi misrepresented the legality and risks of its products to consumers.
Arkansas wants an injunction, repayment to affected customers, restitution of allegedly unlawful proceeds, unpaid taxes and civil penalties. The consumer-protection statute provides for penalties of up to $10,000 per violation, according to the complaint. None of those requested remedies amounts to a court judgment against Kalshi.
As crypto.news previously reported, the state case concerns whether federally supervised event trading can be restricted under Arkansas gambling and consumer-protection laws.
CFTCs dispute with states reaches another court
The Arkansas filing follows the federal governments October lawsuit against Utah. That case sought similar protection for regulated exchanges and their partners after Utah moved to enforce state gambling rules against prediction-market businesses.
In its October 27 announcement, the agencys chairman, Michael Selig, said, “Congress entrusted the CFTC to be the federal regulator with sole responsibility to oversee these markets.” The agency had previously pursued cases against nine other states.
The courts have not reached one uniform position. New Jerseys dispute with Kalshi has reached the Supreme Court, where the state seeks review of a federal appeals decision favoring the exchange. A petition for review does not mean the justices have agreed to hear the case.
A California federal judge has separately restricted Kalshis sports contracts on the lands of two tribes, Blue Lake Rancheria and Chicken Ranch Rancheria, through a preliminary injunction issued November 4. The order applies to specified tribal lands, not California statewide.
Louisiana seeks orders against several prediction markets
The Arkansas dispute unfolded as Louisiana Attorney General Liz Murrill filed her own November 12 lawsuit against Kalshi, Polymarket and other operators, including businesses associated with Robinhood and Coinbase.
“For too long, they have violated our laws with impunity. No longer: I am seeking an immediate restraining order and an injunction to restore the rule of law in Louisiana,” Murrill wrote in an announcement.
Later that day, Louisiana state Judge Jeffrey Johnson issued a temporary restraining order covering event contracts offered to people in the state without a gaming license. The order runs for ten days unless extended, with a hearing on preliminary relief scheduled for November 30.
