PANews reported on September 13th, according to Coindesk, that Massachusetts Attorney General Andrea Joy Campbell has filed a lawsuit accusing the prediction market operator Kalshi of violating Massachusetts gambling laws. The filing alleges that Kalshi's proposed sports betting contracts in January 2025 violated the state's sports betting law, which requires operators to hold a license. Campbell is requesting a court enjoin Kalshi from operating the unlicensed sports prediction market in the state and seeking financial and other relief.
