A White House teleprompter operator used advance knowledge of Trump's speeches to place bets on Kalshi, a prediction market, and made approximately $100,000 over an unspecified period. The operator was placed on unpaid leave pending investigation, marking the first known case of suspected insider trading on a prediction market originating from inside the White House. Federal authorities flagged the activity and are probing whether this constitutes illegal use of inside information. The investigation raises questions about information security and conflict-of-interest protocols for staff with access to sensitive speech content.
