Trump's 1789 Capital Leads $1 Billion Polymarket Funding Round at $21 Billion Valuation

ChainCatcher report, according to CoinDesk, Donald Trump Jr.’s venture capital firm, 1789 Capital, is leading a $1 billion funding round for the prediction market Polymarket, valuing the platform at $21 billion. A spokesperson for the company, Alexa Henning, stated on Monday that 1789 Capital will invest approximately $300 million in this round, following prior cumulative investments of about $200 million. Polymarket’s previous valuation was around $15 billion, making this round a roughly 40% increase in valuation within months. Polymarket and its competitor Kalshi allow users to place bets on outcomes of various events, such as presidential speeches and reality TV star weddings, and both have experienced rapid growth over the past year. The Trump family’s involvement in this sector is also expanding: Donald Trump Jr. became an advisor to Kalshi in 2025 and received shares worth over $300,000, while also providing advisory services to Polymarket. Michael Selig, head of the Commodity Futures Trading Commission (CFTC) appointed by President Trump, has publicly praised these prediction platforms and filed lawsuits against states attempting to regulate the industry. In May this year, Trump posted on Truth Social that prediction markets would thrive under his leadership.
