Detroit warns Robinhood sports contracts threaten city tax revenue
The city of Detroit filed court papers asserting that Robinhood's sports event contracts threaten Detroit's tax revenue and local economy. In a filing that appeared by Wednesday, May 13, Detroit warned that prediction markets offering sports-linked contracts could sidestep state licensing requirements and regulations, potentially diverting activity away from existing state-tax-generating gaming venues. The filing does not cite specific dollar figures or detail the precise mechanism of economic harm. Detroit's intervention is part of broader litigation over whether federally regulated platforms like Robinhood can offer sports-linked contracts without obtaining state gaming licenses, joining a growing list of state and local governments challenging the expansion of CFTC-registered prediction markets into sports wagering territory.
Forces Robinhood to defend against a novel municipal-intervention theory that no other city has tried. A favorable ruling for Detroit would invite similar filings from gaming-dependent cities across 20-plus states, multiplying the venue count beyond the state-AG actions Kalshi already faces.
Adds Detroit to Maryland, Massachusetts, Ohio, and Minnesota as jurisdictions now formally opposing CFTC-registered event-contract platforms, with state and local governments accounting for five of the last six major legal actions recorded in this newsroom's coverage.
