Rhode Island's attorney general has sued prediction market platforms Kalshi and Polymarket, prompting a countersuit from Kalshi. The legal actions challenge the platforms' ability to offer sports-related event contracts in the state.
Rhode Island attorney general Peter Neronha filed suit against Kalshi and Polymarket earlier this week. He accused the platforms of bypassing state rules that restrict sports gambling to a single state-sponsored system. Neronha is seeking a permanent court ban on sports-related event contracts in Rhode Island.
