Arkansas Attorney General Tim Griffin has sued Kalshi in state court, alleging that the prediction market operates an illegal gambling business. The complaint, filed in the Circuit Court of Independence County, relies on the Arkansas Deceptive Trade Practices Act and seeks restitution, civil penalties, unpaid taxes and an injunction against the company's operations in the state. These are allegations in a complaint, not findings by a court.
Griffin's case builds on an October 2025 attorney general opinion, requested by Republican state Senator Bryan King, which concluded that Kalshi's model constitutes gambling under Arkansas law and requires a state gaming license. The complaint argues that the existence of legitimate derivatives does not allow a platform to turn nearly any real-world event into a betting market. In Griffin's words, "When it comes to the majority of its offering, Kalshi is not a risk management tool: It is a pocket-sized bookie."
The age allegation is the part with the most immediate human stake. Griffin says Kalshi lets residents aged 18 to 20 buy event contracts, while Arkansas requires casino customers to be at least 21. If a court accepts that comparison, the question becomes less about labels such as "prediction market" and more about whether an activity that resembles wagering is being offered to people the state's own rules would exclude.
The timing matters. The suit arrives while federal regulators are pushing in the other direction. The Commodity Futures Trading Commission has previously told Kalshi to keep operating in Michigan and New York despite state court orders, and it has since directed exchanges to drop domestic geographic restrictions within 30 days or explain why they cannot. Kalshi and the CFTC will likely argue that federal derivatives law preempts state gambling rules. Arkansas will argue the opposite. Neither position has been resolved in this case.
Kalshi's response to the Arkansas complaint is not in the coverage reviewed here. The open question is practical as much as legal: while the courts decide which regulator governs these contracts, who checks the ages of the people placing them, and what happens to users if the state wins?
