According to The Block, the U.S. Department of Justice (DOJ) and the Commodity Futures Trading Commission (CFTC) have filed a lawsuit against Arkansas Attorney General Tim Griffin, seeking a court order to block the state's enforcement action against Kalshi. In the lawsuit, the federal agencies argue that the relevant event contracts fall under federal regulatory scope and that state-level enforcement infringes upon the CFTC's exclusive jurisdiction. Arkansas previously sued Kalshi on November 4, accusing it of operating an illegal gambling platform. Both parties' claims do not yet constitute a court ruling.
