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 said that 15 minutes before Trump announced the suspension of an airstrike against Iran, there was unusual trading in oil futures, and three Polymarket accounts earned more than 600,000 yuan in profits for accurate predictions, raising concerns about insider trading. The White House emphasized that this behavior violates ethical standards and said there is currently no specific evidence pointing to any individuals who violated the rules.
