US courts and lawmakers face disputes over sports prediction markets
Kalshi and other prediction-market platforms are expanding into sports contracts in the United States, bringing their claimed federal oversight into conflict with state sports-betting rules. Nevada, New Jersey and Maryland have moved to block Kalshi's sports markets, while Kalshi has filed lawsuits challenging those actions; the jurisdictional dispute remains unresolved.
The outcome could determine whether state gambling rules apply to sports event contracts offered by prediction-market platforms.
