U.S. Department of Justice and CFTC Sue Arkansas Over Kalshi Enforcement
The U.S. Department of Justice and CFTC have filed a federal lawsuit seeking to block Arkansas from enforcing state laws against Kalshi.


The U.S. Department of Justice (DOJ) and the Commodity Futures Trading Commission (CFTC) have filed a lawsuit against Arkansas Attorney General Tim Griffin in an effort to block state enforcement actions targeting prediction market platform Kalshi. The complaint, filed on Thursday, November 12, 2026, in the U.S. District Court for the Eastern District of Arkansas, argues that certain event contracts offered by Kalshi should be regulated under federal commodities law. According to a November 13 report by The Block, the federal agencies contend that Arkansas's interference with CFTC-regulated prediction markets conflicts with federal regulatory authority.
What Is the DOJ Seeking in the Kalshi Lawsuit?
At the center of the lawsuit is a fundamental question concerning which authority has jurisdiction over event contracts traded on prediction markets.
Arkansas Attorney General Tim Griffin filed a lawsuit against Kalshi on November 4, alleging that the platform was conducting illegal gambling activities in violation of state laws.
The DOJ and CFTC, however, argue that certain contracts traded on federally regulated platforms such as Kalshi fall under the Commodity Exchange Act (CEA).
According to the federal agencies, these contracts qualify as swaps under federal law, placing regulatory authority over them within the CFTC's jurisdiction.
The agencies are seeking both preliminary and permanent injunctive relief from the court. Their objective is to halt Arkansas's existing enforcement efforts and prevent similar state-level interventions.
However, the filing of the lawsuit does not mean that the court has accepted the federal agencies' legal position.
State and Federal Jurisdiction Clash Over Prediction Markets
The legal dispute involving Kalshi extends beyond Arkansas.
Louisiana Attorney General Liz Murrill also filed a lawsuit on November 12 against several companies, including Kalshi, Polymarket, Robinhood, and Coinbase.
Louisiana authorities argue that prediction market platforms are violating state laws and are seeking court orders that would restrict their operations.
Meanwhile, Kalshi operates in the United States as a prediction market operator subject to federal oversight by the CFTC.
The central legal dispute concerns whether event contracts regulated at the federal level can also be restricted under individual states' gambling laws.
Legal Challenges Expand for Kalshi and Polymarket
Regulatory pressure facing prediction markets has also emerged in several other states in recent weeks.
A temporary court order was issued prohibiting Kalshi from offering contracts related to sporting events on lands belonging to two Native American tribes in California.
Kalshi, however, stated that it had already voluntarily suspended its services in those areas before the ruling.
The outcome of the Arkansas lawsuit could prove significant in defining the boundaries between federal regulatory authority and the powers of individual states to oversee gambling activities.
Nevertheless, the scope of any ruling will depend on the types of contracts examined by the court and the legal arguments considered during the proceedings.
Kriptofoni Assessment
The joint lawsuit filed by the U.S. Department of Justice and the CFTC against Arkansas demonstrates how the regulatory debate surrounding prediction markets has evolved into a direct jurisdictional dispute between federal agencies and state governments.
A ruling in Kalshi's favor could strengthen the legal standing of federally regulated prediction markets. Conversely, a decision supporting Arkansas's position could pave the way for continued restrictions at the state level.
For the cryptocurrency industry, the significance of this development lies in the possibility that blockchain-linked prediction markets, including platforms such as Polymarket, could also be affected by similar regulatory disputes.
