Overview
The companion to Baltimore’s action against Kalshi, filed the same day (August 2026) as a separate suit under the city’s Consumer Protection Ordinance. It is notable mainly for extending municipal enforcement beyond the CFTC-regulated exchanges to Polymarket, whose global venue sits outside the CFTC framework entirely. QCX LLC removed it to federal court on August 17, 2026, where it is before Judge Richard D. Bennett — not Judge Bredar, who has the Kalshi case, so the two Baltimore actions are before different judges. The defendants’ disclosure statements name Intercontinental Exchange, Inc. as an affiliate. No ruling. (Federal docket: City of Baltimore v. QCX LLC, D. Md. No. 1:26-cv-03253, confirmed via CourtListener.)
