Trump Jr. Invests Millions in Polymarket Joins Advisory Board

Donald Trump Jr.’s 1789 Capital has made a double-digit million-dollar investment in Polymarket, a leading prediction platform, while Trump Jr. has joined the firm’s advisory board, signaling a deeper commitment to the growing predictions industry. The investment marks the first major institutional backing from the Trump family’s venture capital arm in the prediction market space and underscores a broader trend of legitimizing speculative trading as a financial instrument [1].

This development follows a key valuation from Founders Fund, which valued Polymarket at over $1 billion, and comes as the company moves to enter the U.S. market. Earlier this year, Polymarket acquired QCEX, a derivatives exchange, for $112 million, gaining a much-coveted CFTC license in the process. This acquisition has paved the way for the company to open its doors to American users for the first time [1].

In a public post on social media, Trump Jr. announced the investment, stating that his firm, 1789 Capital, has "invested in Polymarket" and that he would join as a strategic advisor. He emphasized how prediction markets are "changing the way people follow the news," and expressed pride in supporting the industry’s growth [1].

Polymarket has processed over $6 billion in predictions in 2025, with $3.3 billion specifically tied to last year’s Trump–Harris presidential election. The platform previously excluded U.S. users due to regulatory concerns, but the QCEX acquisition and subsequent regulatory clearances, including the resolution of Department of Justice and CFTC investigations, have allowed the company to prepare for a U.S. launch [1].

The timing of the investment also aligns with Trump Jr.’s broader investment portfolio, which includes stakes in high-growth ventures like Anduril and SpaceX. Polymarket is now seen as an IPO contender, and Trump Jr.’s dual advisory roles with both Polymarket and Kalshi, another regulated U.S. prediction market, place him at the center of an industry poised for mainstream adoption [1].

Despite growing scrutiny from sports leagues and regulators, Trump Jr.’s move reflects a growing institutional belief in the legitimacy of prediction markets as a tool that bridges the gap between betting, financial markets, and political forecasting. His involvement suggests a strategic bet on the future of the sector, even as the boundaries between speculation and investment continue to blur [1].
