Polymarket Gains Investment From 1789 Capital, Led by Donald Trump Jr.

Trump Jr.’s 1789 Capital Backs Polymarket, Joins Advisory Board

Donald Trump Jr. has invested in blockchain prediction market Polymarket through his venture firm 1789 Capital, and will also join the company’s advisory board, the firm said Tuesday.

The move is part of 1789 Capital’s push into crypto infrastructure and alternative finance tools. Axios reported the fund committed tens of millions of dollars after more than a year of talks with Polymarket.

Polymarket allows users to wager on outcomes of elections, legal rulings, and geopolitical events. The platform has processed over $8 billion in bets during the latest U.S. election cycle, surpassing the traffic of sports betting leaders including FanDuel, DraftKings and Betfair.

The company is also finalizing a $200 million funding round led by Founders Fund, boosting its valuation to about $1 billion.

While U.S. customers remain restricted due to regulatory hurdles, Polymarket’s acquisition of QCEX, a CFTC-licensed derivatives exchange, could eventually allow the platform to offer regulated prediction markets domestically.

Prediction markets have been praised for delivering faster and often more accurate sentiment readings than traditional polls, especially in the run-up to elections and major legal decisions.

Trump Jr.’s investment reflects 1789 Capital’s mission to support “American dynamism,” a philosophy gaining traction among conservative venture investors advocating for innovation and economic resilience.
