The White House Office of Management and Budget issued a warning on March 23, prohibiting employees from using non-public information to participate in prediction markets, calling it a criminal offense. The report mentioned that 15 minutes before Trump announced a pause on the Iran airstrike, there was abnormal trading in oil futures, and three Polymarket accounts profited over 600,000 yuan from accurate predictions, raising suspicions of insider trading. The White House emphasized that this behavior violates ethical standards and stated that there is no concrete evidence pointing to any individuals involved in misconduct.
