Commodity Futures Trading Commission Sues Arkansas to Block Kalshi Case

The United States and the Commodity Futures Trading Commission filed a federal lawsuit against Arkansas and Attorney General Tim Griffin on November 12, 2026, asking a court to stop the state’s gambling-law case against Kalshi. The complaint argues that event contracts traded on CFTC-regulated exchanges fall under exclusive federal jurisdiction, rather than Arkansas gambling law.

The case was brought in the U.S. District Court for the Eastern District of Arkansas, with Griffin sued in his official capacity. The federal plaintiffs seek a judgment declaring Arkansas law preempted and invalid as applied to transactions listed, offered or executed on CFTC-regulated designated contract markets. They also request preliminary and permanent injunctions covering the pending Kalshi case and future state investigations or enforcement against CFTC-regulated entities, their affiliates and partners over transactions on those markets.

The Federal Jurisdiction Argument

The federal plaintiffs argue that the Commodity Exchange Act gives the CFTC exclusive jurisdiction over futures, options and swaps traded on federally regulated exchanges, and that the event contracts targeted by Arkansas are swaps. Payments can depend on an event’s occurrence, nonoccurrence or extent, while the contracts also operate as binary options with either a fixed payoff or zero. KalshiEX is a CFTC-approved designated contract market, an exchange operating under commission oversight.

Under that system, an exchange supplies a contract’s rules, an explanation of its terms and a certification of compliance before listing. The CFTC can demand supporting information, stay a listing or order a noncompliant contract removed. The federal complaint argues that allowing individual states to prohibit or condition those listings would undermine that self-certification process and create the prospect of 50 regulators.

On November 5, 2026, the CFTC issued an interpretation covering impartial access, the requirement that designated contract markets provide competitive, open, fair and impartial access. The markets must end domestic geographic restrictions that violate those requirements within 30 days or explain to the Division of Market Oversight why compliance is not feasible. The federal plaintiffs contend that Arkansas’s enforcement would force exchanges to deny event contracts to Arkansas residents, creating a direct conflict with the federal access requirement.

The Arkansas Enforcement Action

Arkansas filed its lawsuit against KalshiEX LLC and Kalshi Inc. on November 4, 2026. Griffin’s office alleges that Kalshi offered unlicensed real-money wagering on sports, elections and entertainment to Arkansas consumers, including people as young as 18, without obtaining licenses, submitting to oversight or paying the taxes required of lawful gambling operators. The state brought claims under the Arkansas Deceptive Trade Practices Act and is seeking restitution, civil penalties, unpaid taxes and injunctive relief. Griffin summarized its position: “Arkansas law is concerned with substance, not semantics.”

Federal Rules Distinguish Gambling From Event Contracts

The CFTC separately addressed that distinction in an interim final rule published October 9, 2026, which excludes casino-style gambling products, including sportsbook wagers and casino games, from the swap definition. A separate proposal released that day would expressly include event contracts based on sports, politics, culture and weather. The federal complaint describes the interim rule as having the force of law; the event-contract measure remains a proposal.

The federal complaint places the case within a wider campaign, citing earlier preemption actions across the country and preliminary injunctions favoring the federal position in Arizona, Illinois and Minnesota.

The request for preliminary relief puts Arkansas’s ability to continue the state case directly before the federal court. The broader decision will determine whether state consumer law can reach the targeted exchange-traded contracts or whether their regulation rests exclusively with the CFTC.
