If the legalization of sports betting reshaped the way Americans view sports, the emergence of prediction markets and government questions about sporting integrity might reshape the way Americans view sports betting. Prediction markets, where users can bet on the yes/no outcome of events, have quickly gained momentum this year despite legal challenges and regulatory uncertainty. The NFL questioned the oversight of prediction markets and its implications for sporting integrity in congressional testimony last week. The newly formed Coalition for Prediction Markets, which represents many of the largest operators in the space, including Kalshi, disputed Miller's testimony. McGinley said prediction market companies are obligated to report their data to the CFTC, which employs "sophisticated market surveillance tools."
