Robinhood files federal suit to preempt Massachusetts action against Kalshi prediction markets
Summary
Robinhood has launched a federal lawsuit in the US District Court in Boston seeking to stop Massachusetts officials from applying the state’s gambling laws to prediction markets it offers via Kalshi. The platform argues Kalshi is a CFTC-regulated designated contract market and that state action would be pre-empted by the Commodity Exchange Act.
The move follows a suit by Massachusetts Attorney General Andrea Campbell against Kalshi in Suffolk Superior Court, which accuses Kalshi of operating illegal online sports betting in the commonwealth. Robinhood says it merely facilitates customer orders for Kalshi markets from within Robinhood accounts and is therefore exposed to potential state enforcement.
Key Points
- Robinhood filed a federal suit naming the Massachusetts Attorney General and Massachusetts Gaming Commission to pre-empt state enforcement of gambling laws.
- Robinhood’s defence rests on Kalshi being a CFTC-designated exchange and on federal pre-emption under the Commodity Exchange Act.
- The Massachusetts AG alleges Kalshi is offering unlawful online sports betting and sought an order to stop those markets while the case proceeds.
- Robinhood began offering Kalshi’s football prediction markets this season and fears similar state complaints could cause irreparable reputational and financial harm.
- Kalshi and Robinhood are facing related legal challenges in multiple US states; Kalshi previously won injunctions in New Jersey and Nevada.
- Regulatory tension continues between state regulators and federal oversight (CFTC) over the classification and control of prediction markets.
- Robinhood has prior regulatory history in Massachusetts, including a 2024 settlement and fine over trading practices.
