Kalshi posts $500 million trading volume during Masters as prediction markets face rising regulatory pressure

Prediction market platform Kalshi said it recorded $500 million in trading volume during the Masters golf tournament. A post on X showed trading across winner, player and side-bet markets for the event in Augusta, Georgia, and said weekend activity rose as funds flowed in from retail investors to hedge fund participants. The surge comes as prediction markets grow around sports events and face increased regulatory pressure and market surveillance.
