Illinois Judge Blocks Prediction Market Rules as Ohio Orders 10 Platforms to Halt Sports Betting
A federal judge in Illinois blocked new state rules on prediction markets, ruling that Kalshi’s sports contracts are likely federally regulated swaps. Meanwhile, Ohio’s casino regulator ordered 10 platforms, including Polymarket and Robinhood, to stop offering sports contracts by October 16, citing a recent 6th Circuit ruling. This creates a fragmented legal landscape where the same app faces different regulations in different states.
