Donald Trump Jr Joins Polymarket Board After 1789 Capital Investment

Donald Trump Jr. has joined the advisory board of Polymarket, a major prediction market platform, following a strategic investment from his venture capital firm, 1789 Capital [1]. This move is seen as a key step in Polymarket’s efforts to reestablish itself in the U.S. market, where it previously faced regulatory action that forced it to block American users. The investment, estimated at “double-digit millions of dollars” by Axios, indicates a growing political and financial alignment between the platform and influential U.S. figures [1].

In a public statement, Trump Jr., who became a partner in 1789 Capital in 2024, said that Polymarket “cuts through media spin and so-called ‘expert’ opinion by letting people bet on what they actually believe will happen in the world” [1]. His involvement brings significant political attention to the platform, which allows users to wager on a wide range of events, including political elections and entertainment outcomes.

Polymarket’s return to the U.S. market is underpinned by a $112 million acquisition of QCEX, a derivatives exchange licensed by the Commodity Futures Trading Commission (CFTC), in July 2025 [1]. This acquisition coincided with the conclusion of investigations by both the CFTC and the Department of Justice, which had previously scrutinized the company. The move is viewed as a critical step toward regulatory compliance and a broader strategy to expand in the U.S.

The platform’s rapid growth has also brought increased scrutiny. In 2022, the CFTC fined Polymarket $1.4 million for operating an unregistered swaps platform and ordered it to block U.S. users [1]. During the 2024 presidential election, the platform handled over $3.6 billion in bets, with more than $2.7 billion on the Trump–Harris matchup alone [1]. This surge in political betting has raised concerns among lawmakers, including Senators Elizabeth Warren and Jeff Merkley, who have called for a ban on election betting, arguing it could damage public trust in the electoral process [1].

In addition to political concerns, Polymarket has also drawn criticism from the sports industry. The National Football League (NFL) has warned that prediction markets like Polymarket could pose integrity risks due to a lack of the compliance systems found in licensed sportsbooks [1]. Despite these concerns, Polymarket has continued to grow, announcing a $200 million funding round in July 2025 that valued the company at $1 billion [1]. The company also launched a U.S. rulebook and digital advertising campaigns to promote its return to the American market.

The partnership with 1789 Capital and the inclusion of Trump Jr. on Polymarket’s advisory board represent a broader strategy to strengthen the platform’s position in the U.S. and align with influential political and financial interests. While regulatory and political challenges remain, the platform’s recent compliance efforts and high-profile endorsements suggest it is positioning itself to play a significant role in the future of financial and political prediction markets [1].
