St. Louis, MO, September 18, 2026 — Missouri Attorney General Catherine Hanaway has taken action against six prediction market companies, ordering them to cease operations within the state. The action, formalized through cease-and-desist letters, targets platforms like Polymarket and Kalshi, which offer what the Attorney General’s office characterizes as “event contracts.”
According to the Attorney General’s office, these event contracts constitute unlicensed sports betting. The letters aim to enforce Missouri’s existing laws governing sports wagering. These regulations typically require entities engaged in such activities to obtain proper licensing, remit applicable taxes to the state, and implement measures to restrict access to individuals of legal age.
The specific companies identified in the cease-and-desist letters include Polymarket and Kalshi, among four others whose names were not immediately provided. The directive mandates that these companies must stop offering their event contracts to Missouri residents.
The Attorney General’s office stated that the enforcement of regulated sports wagering laws is intended to ensure a fair and legal market within the state. This includes upholding consumer protection standards and preventing unregulated gambling activities.
The notice from the Attorney General’s office signifies a move to bring prediction market operations in line with established gaming and betting regulations in Missouri. Further details regarding the timeline for compliance or potential next steps if the companies do not comply were not immediately available.
