Missouri Sends Orders to Polymarket and Kalshi

What Missouri did

Missouri has sent cease-and-desist orders to Polymarket and Kalshi, placing both platforms under the same type of state enforcement action. A cease-and-desist order directs a recipient to stop conduct identified by the issuing authority. It is not, by itself, the same as a criminal conviction or a final court ruling.

The orders make the next steps a legal and administrative question. Their practical effect will depend on what conduct Missouri identified, which state authority issued them, any deadline for compliance, and the procedures available for a response or challenge. Those details determine whether the platforms must make immediate operational changes in Missouri and how either dispute could proceed.

Why the action matters

The development concerns state oversight of Polymarket and Kalshi rather than a candidate, campaign or scheduled election. No Missouri race is directly linked to the orders.

For residents, the key point is that the state has taken a formal step against each platform. Further steps could include compliance, administrative review if that route is available, or court review where permitted. The precise path depends on the orders and Missouri law.

Public records from the issuing state authority would establish the stated legal basis, scope and effective date of each order. Filings or official statements from Polymarket and Kalshi would show how each plans to respond. Any later administrative decision or court filing could clarify whether the orders remain in force, are changed or are set aside.
