The White House sent an email to its employees warning them against misusing their positions to conduct insider trading and futures contracts. The Wall Street Journal reported this, citing sources familiar with the matter, who noted that the email was sent to employees on March 24. According to the report, about 15 minutes before U.S. President Donald Trump announced the ceasefire with Iran, oil futures contracts worth more than $760 million were closed. It was also reported that recently three Polymarket accounts earned more than $600,000 from correctly betting on the timing of the ceasefire.
