Trump Jr. Joins Polymarket as Platform Strengthens U.S. Presence and Secures Funding

Polymarket, the prediction-making platform, is strengthening its presence in U.S. politics and finance. The company has appointed Donald Trump Jr., the son of the U.S. president, to its advisory board while also gaining new financial backing from 1789 Capital, a venture capital firm that identifies itself as focused on supporting the next era of “American exceptionalism.”

New Investment and Leadership Addition

The appointment of Trump Jr. and the backing from 1789 Capital reflect Polymarket’s growing influence in the prediction market sector. While financial terms were not disclosed, Reuters reported the investment was in the double-digit millions, signaling strong interest in the platform’s rapid growth and its expanding role in event-based trading.

Trump Jr., in taking on the advisory role, called Polymarket the largest prediction market in the world. He said the platform is important for the United States and emphasized its ability to provide insight into what people truly believe will happen in politics and other areas.

Polymarket cuts through media spin and so-called ‘expert’ opinion by letting people bet on what they actually believe will happen in the world. I am pleased that 1789 Capital is investing in Polymarket and am honored to join the company’s advisory board. I look forward to working with the team to advance its mission of bringing truth and transparency to everyone – including the U.S.

Polymarket’s Rapid Growth and Investor Support

Polymarket was launched in 2020 by founder and CEO Shayne Coplan. The platform allows trading on topics ranging from elections to celebrity events. In just the first half of this year, the platform recorded $6 billion in activity, with millions of dollars moving through it every day. This rapid growth has brought attention from both traders and regulators.

The company’s visibility increased sharply during the 2024 U.S. presidential election. During the campaign, more than $3.6 billion in trades were placed on the platform, with about $2.7 billion focused on the Trump–Harris contest.

1789 Capital, which provided the new investment, was established in 2022 by Omeed Malik and Chris Buskirk. Malik said Polymarket combines financial innovation with free expression and that it delivers real-time clarity at a moment when information can be difficult to interpret. He stated that the firm is proud to support Polymarket’s vision.

Polymarket Strengthening U.S. Presence Through Key Moves

In addition to the capital raise, Polymarket has taken other significant steps this year. The company strengthened its U.S. position in July 2025 by acquiring QCEX, a CFTC-regulated derivatives exchange, in a transaction worth $112 million.

This purchase opens the way for the betting platform to operate more directly in the U.S. market with regulatory approval. Polymarket has also teamed up with X as its official prediction market partner, a move that could expand its online discussion.

Broadly, prediction markets function by letting people trade contracts tied to upcoming events. As demand shifts, the value of these contracts moves up or down, creating a picture of what traders think will happen. Unlike traditional surveys, which capture opinions at a single moment, these markets offer continuous updates that reflect changing sentiment in real time.
