Robinhood sues Massachusetts over state authority on Kalshi prediction markets
Robinhood filed a federal lawsuit against the Massachusetts attorney general and Massachusetts Gaming Commission, seeking to prevent state gambling enforcement against sports prediction markets it offers through Kalshi. Robinhood argues that federal regulation of Kalshi’s markets means Massachusetts gambling laws do not apply; the state attorney general separately alleges Kalshi offers sports betting without complying with state law and has asked a court to halt those markets while her case proceeds.
The cases could determine whether Massachusetts can apply its gambling laws to sports prediction markets offered through Robinhood and Kalshi.
