Former U.S. President Donald Trump's oil and gas stock holdings may have surged by up to $15.5 million this year, with an average return of approximately 39%, as energy stocks soared during the war with Iran, according to a new report from Democrats on the Joint Economic Committee of Congress. The report indicates that as of August 17, the estimated value of these holdings ranged between $17.2 million and $61.1 million. Democrats also stated that Donald Trump purchased an additional $3.6 million in oil and gas stocks in the first three months of 2026, including Chevron shares bought in the weeks following U.S. actions against Venezuela. Democrats anticipate that if they regain control of both chambers of Congress in the November midterm elections, they will subject Donald Trump's stock trades to stricter scrutiny.
