Prediction market platform Kalshi is reviewing three wagers placed less than 20 minutes before news outlets reported Katie Zacharia's appointment. The bets, which stood to pay out approximately $9,600 combined, were flagged for potential insider trading activity. The Wall Street Journal reported that two of the suspicious bets landed on the platform shortly before the public announcement. Kalshi has initiated a review process to determine whether traders had access to non-public information regarding the appointment.
