Donald Trump Jr Joins Polymarket Advisory Board as 1789 Capital Invests Double-Digit Millions

Donald Trump Jr. has joined the advisory board of prediction market platform Polymarket, signaling a strategic deepening of the firm’s ties with high-profile political figures. The move follows a significant investment from 1789 Capital, a fund co-founded by Trump Jr. and Chris Buskirk, which brands itself as aligned with “American exceptionalism.” The investment, estimated by Axios to be in the range of “double-digit millions of dollars,” underscores the growing political and financial alignment between Polymarket and the Trump family [1].

Trump Jr. emphasized in a statement that Polymarket enables users to “cut through media spin and so-called ‘expert’ opinion” by allowing them to bet on what they genuinely believe will happen. As a partner in 1789 Capital since 2024, Trump Jr. brings a wealth of business and strategic insight to Polymarket’s leadership team, further enhancing the company’s credibility and influence in both the U.S. and global markets [3].

This partnership aligns with Polymarket’s broader strategy to re-enter the U.S. market under regulatory compliance. In July 2025, the company acquired QCEX, a CFTC-licensed derivatives exchange and clearinghouse, for $112 million. This acquisition, along with the closure of CFTC and DOJ investigations, marks a critical step toward Polymarket’s legal reentry into the U.S. market [1].

Polymarket, which launched in 2020, has quickly become one of the world’s largest prediction markets, facilitating millions in daily volume. During the 2024 U.S. presidential race, the platform processed over $3.6 billion in bets, with nearly $2.7 billion tied to the Trump–Harris matchup. This surge drew scrutiny from lawmakers, including Senators Elizabeth Warren and Jeff Merkley, who called for the outright ban of election betting [1].

Despite regulatory challenges, Polymarket continues to expand. The company is reportedly finalizing a $200 million funding round that values it at $1 billion. By August 2025, it had launched a U.S. rulebook and begun promoting its domestic return through digital ads. With Trump Jr. now on the advisory board and new investment in place, Polymarket is repositioning itself not just as a crypto prediction platform but as a major player in the political and financial landscape [1].

The platform’s CEO, Shayne Coplan, described the investment as a “significant milestone” that will help reinforce Polymarket’s role as a trusted source of real-time market data. Omeed Malik, founder of 1789 Capital, highlighted Polymarket’s intersection of free expression and financial innovation, noting its value in a world “clouded by noise” [4].

As the prediction market space becomes increasingly competitive, Polymarket’s move to align with Trump Jr. and a politically aligned investment vehicle could provide a strategic edge. The partnership is seen as a way to bolster the platform’s legitimacy, particularly as it navigates regulatory and political pressures while expanding its reach in the U.S. [7].

The addition of Trump Jr. to the advisory board is expected to amplify Polymarket’s visibility and credibility, reinforcing its mission to provide real-time insights into public sentiment on global events.
