The exchange is asking for a declaratory judgment and a permanent injunction.The complaint also says Hanaway “incorrectly addressed” her letter to Foris DAX, Inc. instead of the exchange. It adds that getting a sports betting license is not possible. Missouri’s constitution allows only two direct mobile sports wagering licenses, and both have been awarded.Novig filed its lawsuit in Missouri’s Eastern District through its exchange operator, Ludlow Exchange LLC. The company is asking for both a preliminary and a permanent injunction. Novig has already sued officials in several other states, including Wisconsin.Novig argues the court should keep things as they are while a related appeal moves forward.

The 6th and 9th Circuits ruled against Kalshi, while the 3rd Circuit sided with it.Kalshi was the first of the six companies to respond to Hanaway’s letters. On Oct. 2, Spectrum News reported that the attorney general’s office described “ongoing discussions” with the company.Underdog sued Connecticut last month over a similar crackdown.
