KANSAS CITY — The CFTC-registered exchange behind Crypto.com’s OG prediction-market brand has sued Missouri’s attorney general and gaming regulators in federal court, a month after the state ordered it to stop offering sports event contracts to Missourians. The complaint in North American Derivatives Exchange, Inc. d/b/a OG.com Prediction Markets v. Hanaway (W.D. Mo., No. 4:26-cv-00969) was filed on 16 October 2026, the same day Novig sued the attorney general and gaming regulators in the state’s other federal district. It names Attorney General Catherine L. Hanaway, Missouri Gaming Commission Executive Director Michael A. Leara, Commission Chair Jan M. Zimmerman and the four other commissioners, all in their official capacity. The court docket assigns the case to Judge Greg Kays and, as of 20 October, shows no ruling.
What Missouri demanded
The attorney general’s cease-and-desist letter, dated 16 September 2026, calls Crypto.com an online sports wagering platform taking bets from people in Missouri without submitting to regulation by the Missouri Gaming Commission. It demands that the company stop or comply with state licensing, the 10% wagering tax on adjusted gross revenue and licence fees of up to $500,000, and gives it 30 days. The letter also notes that Crypto.com’s terms allow users from age 18, while Missouri sports wagering requires players to be 21. On 17 September the office announced letters to six companies: Polymarket, Kalshi, Crypto.com, Novig, Underdog and Robinhood.
The exchange’s case
According to the complaint, North American Derivatives Exchange has been a CFTC designated contract market since 2004 and launched OG.com in February 2026 as a separate platform for its event contracts; Crypto.com announced OG on 3 February. The filing says the letter was wrongly addressed to Foris DAX, Inc. (“Crypto.com”) instead of the exchange. It argues that sports event contracts listed on a DCM are swaps under the Commodity Exchange Act, that the CFTC has exclusive jurisdiction over them and that Missouri’s gambling laws are preempted as applied to OG.com. It also says that licensing is not a practical alternative: Missouri’s constitution allows only two direct mobile sports wagering licences, both already awarded. The exchange asks for a declaratory judgment and a permanent injunction; unlike Novig’s complaint, it does not ask for a preliminary injunction. The complaint cites the CFTC’s 9 October proposed rule and interim final rule, which we covered in our post on the event-contract swap rule and casino exclusion. None of these claims has been tested in court.
The fifth state in 18 months
Missouri is the fifth state this exchange has taken to federal court, according to the CourtListener index checked on 20 October. The earlier suits were filed in Maryland on 21 April 2025, Nevada on 3 June 2025, New York on 12 June 2026 and Washington on 22 July 2026; the Nevada case was appealed to the Ninth Circuit (No. 25-7187). The chart above shows the gaps between filings. The index may be incomplete, and it counts filings, not their outcomes. Missouri’s letter itself cites the federal court ruling against the exchange in Nevada in 2025 among the decisions that, in the state’s view, reject preemption.

Why it matters for GambleFi
Missouri now faces two federal suits over the same letters, and both lean on the CFTC’s October line between event contracts and casino-style gambling. A ruling in either court would show whether a federal designation can override a state that already licenses its own sportsbooks. On-chain prediction markets sit outside this fight but carry their own risk. World Bet, a World Cup market on Solana, was closed by its own team mid-tournament; its story is in our GambleFi Graveyard. Offshore on-chain exchanges such as SX Bet restrict US users altogether. This is a report on a court filing, not legal or betting advice. In Missouri, legal sports wagering runs through operators licensed by the Missouri Gaming Commission, and players must be 21 or older.
