Kalshi is facing another significant legal battle in the United States, and this time federal regulators have stepped in directly on the platform's side. The US Department of Justice (DOJ) and the Commodity Futures Trading Commission (CFTC) have moved against Arkansas over its efforts to restrict the prediction-market operator, sharpening a wider dispute over whether prediction markets — platforms where users trade contracts tied to the outcomes of real-world events — should fall under federal commodities regulations or state gambling laws.

Federal Agencies Sue Arkansas Attorney General

On November 12, the DOJ and the CFTC filed a lawsuit against Arkansas Attorney General Tim Griffin. The federal agencies are seeking to prevent the state from enforcing its gambling laws against Kalshi and other federally regulated prediction-market platforms.

The complaint rests on a jurisdictional argument. The agencies contend that the Commodity Exchange Act gives the CFTC exclusive jurisdiction over certain financial contracts traded on regulated platforms. According to the reports, the federal complaint describes Kalshi's event contracts as swaps covered by federal commodities law, arguing that Arkansas cannot use state gambling laws to restrict products that fall under federal oversight.

The legal challenge follows an earlier lawsuit filed by Attorney General Tim Griffin against Kalshi on November 4. The federal lawsuit, filed just eight days after the state's action, marks a significant escalation in the dispute, directly challenging a state's attempt to apply its gambling laws to products the CFTC considers federally regulated.

Why Arkansas Considers Kalshi an Illegal Gambling Platform

In its official November 4 announcement, the Arkansas Attorney General's Office accused Kalshi of operating an illegal gambling platform in the state. The office alleged that users could wager money on elections, reality television competitions, football games and other events without the licences required for lawful gambling operators.

"Arkansas law is concerned with substance, not semantics," Attorney General Tim Griffin said.

The state also alleged that Kalshi violated the Arkansas Deceptive Trade Practices Act, and is seeking restitution, penalties, taxes and injunctive relief.

The disagreement centres on how these contracts should be classified. Arkansas considers them gambling activities, while Kalshi maintains that its products are financial contracts regulated under federal law.

The CFTC's Position on Federal Jurisdiction

The CFTC has previously defended its authority over prediction markets in disputes with state governments. In a May 12, 2026, official announcement, the commission said it had filed an amicus brief in the US Court of Appeals for the Sixth Circuit, reaffirming its exclusive jurisdiction over prediction markets.

"The CFTC will not allow overzealous state governments to undermine the agency's longstanding authority over these markets," CFTC Chairman Michael S. Selig said in the announcement.

The statement concerned a separate case involving KalshiEX LLC, but it offers insight into the regulator's broader position in the ongoing dispute over federal and state authority.

Arkansas Is Not the Only State Suing Kalshi

Utah Attorney General Derek Brown has also filed a lawsuit, alleging that the platform violates the state's gambling laws. In its official announcement, the Utah Attorney General's Office outlined its concerns about Kalshi's event contracts and their availability to state residents.

The dispute has also drawn attention to the differences between prediction markets and traditional sportsbooks. In an opinion article shared by The Wall Street Journal on X, Chris Christie examines Kalshi's argument that its contracts are financial products rather than ordinary sports bets. The article also discusses Utah's concerns about the platform's trading structure.

From @WSJopinion: "Peer-to-peer" wagering isn't gambling? Don't bet on it. Kalshi says it is different from a sportsbook. Utah says Kalshi's own trading arm acts like the house, writes @GovChristie. — The Wall Street Journal (@WSJ) November 13, 2026

These separate legal challenges highlight a growing disagreement over whether prediction markets should fall under federal commodities regulations or state gambling laws.

Expansion Plans Move Ahead Amid Regulatory Pressure

The legal disputes come as Kalshi explores further business expansion. On November 12, Reuters reported that the company was in talks to raise funds at a potential $65 billion valuation to develop a platform for trading compute futures.

The proposed expansion could take Kalshi beyond event contracts and into markets linked to computing resources, including cloud computing and GPU capacity. Still, its growing regulatory challenges could create uncertainty as the company explores new business opportunities.

The outcome of the Arkansas dispute could influence how other states approach prediction-market platforms. For now, the disagreement between federal regulators and state authorities remains unresolved.
