Trump Jr.'s Investment Firm Reports 200% Returns, Boosted by Polymarket Growth

Donald Trump Jr.'s investment firm, 1789 Capital, has reportedly achieved a return of approximately 200%, largely driven by an early stake in prediction market platform Polymarket. The firm's main fund reached this performance as of June 30, significantly outperforming the average venture capital returns for firms started in 2023. Polymarket’s valuation has surged from around $300 million to over $15 billion following regulatory changes under the Trump administration, including a CFTC license and withdrawal of restrictions on political prediction markets. The firm also holds stakes in companies like SpaceX, Anduril, and Vulcan Elements — some of which have seen substantial valuations or government contracts. The success has drawn scrutiny over potential conflicts of interest, particularly regarding 1789 Capital’s role with Kalshi (a Polymarket rival) and its ties to a Defense Department loan for Vulcan Elements. Trump Jr., who serves as an adviser to Kalshi, denies any influence on the loan decision.
