Kalshi (KAL) and Polymarket Face Congressional Probe Into Insider Trading

Rep. James Comer, chair of the House Oversight Committee, announced an investigation into Kalshi and Polymarket for their measures against insider trading. He sent requests for documentation on how both companies implement identity verification and prevent anomalous trading activities. This investigation follows a rise in the popularity of prediction markets and concerns about potential insider trading by government officials. As Kalshi is regulated by the CFTC and Polymarket operates with less oversight, the outcome of this inquiry may lead to stricter regulations in the prediction market sector.
