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

Donald Trump Jr., through his venture firm 1789 Capital, has invested in blockchain-based prediction market Polymarket and will join its advisory board, according to a company announcement Tuesday.

The investment underscores 1789 Capital’s growing focus on crypto infrastructure and alternative finance. Axios reported that the firm committed tens of millions of dollars to Polymarket after 18 months of discussions.

Polymarket allows users to wager on real-world outcomes — from elections and geopolitical events to court rulings — and has seen rapid adoption. During the last U.S. election cycle alone, the platform processed more than $8 billion in volume, surpassing major online betting operators such as FanDuel, DraftKings, and Betfair in traffic.

The company is nearing completion of a $200 million funding round led by Peter Thiel’s Founders Fund, valuing the platform at $1 billion.

Currently, U.S. users are restricted from participating in Polymarket due to regulatory limits, but its recent acquisition of derivatives exchange QCEX — which holds a license from the Commodity Futures Trading Commission (CFTC) — could pave the way for a compliant U.S. launch.

Prediction markets are increasingly viewed as fast, accurate gauges of public sentiment compared with traditional polling. Ahead of major elections or rulings, they often provide real-time insights into market expectations.

For Trump Jr.’s 1789 Capital, the investment reflects its stated mission of backing technologies that advance “American dynamism,” a concept popular in conservative venture circles emphasizing domestic innovation and resilience.
