Rhode Island sues Kalshi and Polymarket over alleged illegal sports gambling
Attorney General Peter Neronha filed a 32-page complaint in Providence County Superior Court alleging that prediction-market operators Kalshi and Polymarket are conducting sports betting while evading state gambling laws. The platforms' sports-related "event contracts" are functionally no different from traditional sports betting, the complaint argues. Kalshi preemptively filed its own federal lawsuit the same day, arguing it is subject only to federal derivatives-trading regulations.
