Distribution and platforms: Can we ship through apps and platforms?

Robinhood and Webull's role distributing Kalshi's event-contract products to Maryland residents, and Coinbase's role providing crypto on-ramp access to the same products, are now directly at issue in Baltimore's August 2026 municipal lawsuit. All three are named not as originators of the contested contracts but as distribution and funding-access co-defendants under the city's Consumer Protection Ordinance, extending accessory-liability theory to platforms that did not themselves create the disputed product. This tests a previously unadjudicated theory in Maryland: that a brokerage app, retail trading platform, or crypto exchange distributing or funding access to a product a state regulator has determined is indistinguishable from a sports wager can be held liable alongside the originating platform. The relief sought, injunction, disgorgement, restitution and civil penalties, would apply to these distribution partners as well as to Kalshi and Polymarket directly.
