Crypto.com and Novig sue Missouri over sports event contracts; Kalshi and Polymarket hold off

Crypto.com and Novig have sued Missouri officials in federal court over sports event contracts, according to The Block. The lawsuits follow a September directive from Missouri Attorney General Catherine Hanaway to stop offering those contracts.

Two firms challenge Missouri’s directive

Hanaway’s order targeted six firms. Crypto.com and Novig are the two identified in The Block’s report as having brought federal challenges.

Kalshi and Polymarket have held off on suing, according to the report published Oct 18, 2026. The available summary does not explain their decisions.

The source’s full text was unavailable. The supplied material does not identify the companies’ legal arguments, the relief they seek or any court response, limiting what can be concluded about the litigation’s likely effect on sports event contracts in Missouri.

What it means for prediction markets

• The state dispute has reached federal court. Crypto.com and Novig are challenging Missouri officials following the September stop-offering directive, but the available material establishes no ruling or change in access.
• The firms’ responses differ. Kalshi and Polymarket have not joined the reported litigation. That distinction alone does not establish how any of the firms will ultimately respond to Missouri’s order.
