Prediction market Kalshi is investigating wagers placed on Katie Zacharia’s selection as press secretary before the news became public. Bets totaling approximately $173 were made prior to media reports confirming her appointment, raising concerns about potential insider information. The contract ultimately settled as "Yes," but Kalshi has blocked withdrawals related to these trades under exchange rules that permit freezes during active investigations. The probe highlights ongoing regulatory scrutiny of prediction markets and their vulnerability to informed trading ahead of political announcements.
