James Comer, the Chief Republican of the U.S. House Oversight Committee and a Kentucky Congressman, has expanded his investigation into insider trading in the prediction market by sending letters to the CEOs of Hyperliquid Labs, Crypto.com, and PredictIt's parent company, Aristotle Exchange, requesting customer identification (KYC) and suspicious transaction monitoring processes. James Comer launched a similar investigation into Kalshi and Polymarket in May this year, stating that some platforms failed to effectively prevent the use of undisclosed information for betting.
