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.
