Wisconsin sues exchanges over illegal sports betting

Wisconsin has filed a civil complaint in Dane County Circuit Court, alleging that Kalshi, Robinhood, and Coinbase are facilitating illegal sports betting. The state claims these companies are operating unlawful prediction markets and event contracts that function as disguised sports wagering under Wisconsin law. Sports betting is generally illegal in Wisconsin, with few exceptions for tribal gaming operations.

The lawsuit asserts that the platforms' "prediction markets" and "event contracts" are essentially sports bets, despite being framed as financial trading. Wisconsin cites the example of betting on NCAA college basketball tournament outcomes, including point spreads and specific game events, as evidence of these disguised gambling activities. The state argues that the pricing structure, tied to implied probabilities of outcomes, and the binary payout system mirror traditional betting.
