Golden Finance reported that on November 13, local time, the FBI seized the mobile phones and electronic devices of Polymarket CEO Shayne Coplan. According to the New York Post, the FBI raided Coplan's residence in Soho, New York, and demanded the surrender of electronic devices. This action took place eight days after Polymarket successfully predicted that Trump would win the 2024 presidential election, with a platform transaction volume of over $3 billion. Anonymous sources said that the FBI may suspect that the platform is manipulating the election market and believes that this move is a "political retaliation" by the previous government against Polymarket. At present, the FBI has not responded to the incident, and Coplan has not made any public comments.
