Massachusetts Attorney General Andrea Joy Campbell today filed a lawsuit in Suffolk Superior Court against KalshiEX LLC (“Kalshi”) — a self-described online “prediction market” — for promoting and accepting online sports wagers from Massachusetts customers without following the many Massachusetts laws that govern sports gaming, including licensure by the Massachusetts Gaming Commission (MGC).  

“Sports wagering comes with significant risk of addiction and financial loss and must be strictly regulated to mitigate public health consequences,” said AG Campbell. “This lawsuit will ensure that if Kalshi wants to be in the sports gaming business in Massachusetts, they must obtain a license and follow our laws. I am grateful for the ongoing partnership with the Gaming Commission.”
