最新报道:Prediction markets platform Kalshi has become CNN's official prediction markets partner, with its real-time probability data on future events to be integrated into CNN's reporting and programming under Chief Data Analyst Harry Enten. The partnership includes a new Kalshi-powered news ticker. Rival Polymarket's CEO recently called prediction markets "the most accurate thing we have" for forecasting. The sector, with combined cumulative volume exceeding $45 billion, is gaining mainstream traction through partnerships with major firms like Google Finance, but faces criticism and legal challenges, including a class action lawsuit accusing Kalshi of operating an unlicensed sports betting service.
