Kalshi sues Missouri, calls cease-&-desist impossible to meet

Nadex, which runs Crypto.com-backed OG.com, sued Utah the same day the CFTC filed a federal complaint, citing similar jurisdiction arguments.

The hit

Kalshi has filed a federal lawsuit against Missouri, arguing the state’s cease-&-desist order against its sports-event contracts offers no realistic path to compliance, according to SBC Americas. The suit names Attorney General Catherine Hanaway & the Missouri Gaming Commission. It follows a cease-&-desist letter demanding Kalshi stop offering sports contracts or get licensed.

Why it matters

Kalshi says federal law gives the CFTC exclusive jurisdiction over event contracts, so state gambling rules can’t apply. It also argues Missouri’s licence routes are effectively closed to it, since two mobile sports betting licences already went to DraftKings & Circa Sports & others require casino or sports-team ties.

The record

Cease-&-desist letter issued	16 September (Missouri)
Original compliance deadline	16 October, extended to 30 October (Missouri)
State refused enforcement guarantee	Tuesday, per Kalshi (Missouri solicitor general)
Parallel case	Nadex, which runs Crypto.com-backed OG.com, sues Utah same day as CFTC federal complaint
Utah’s own suit against Kalshi	Filed 20 October, seeks to block contracts & recover alleged losses

What happens next

Kalshi intends to seek a preliminary injunction; Missouri’s extended compliance deadline falls on 30 October.
