Donald Trump Jr. Backs New $1 Billion Investment in Polymarket

Quick Glance at the Facts

• Polymarket’s current funding round is nearly $1 billion, thanks to a $300 million investment from 1789 Capital.
• President Trump’s son, Don Jr., is an investment partner in 1789 Capital.
• Don Jr. also serves on Polymarket’s advisory board, and the latest funding round brings Polymarket’s valuation to $21 billion.

Polymarket’s latest funding round is nearing $1 billion, thanks to a large investment from 1789 Capital. The firm, which is partnered with Donald Trump Jr., has already invested heavily in Polymarket and is contributing another $300 million. Don Jr. is also a member of the Polymarket advisory board, and the latest investment helps cement the partnership between two of his business interests.

Polymarket’s $1 Billion Funding Round

Polymarket continues its push to catch up to Kalshi as the top prediction market. Its recent funding round is set to reach $1 billion, thanks in large part to another huge investment from 1789 Capital.

The investment firm, which is partnered with Donald Trump Jr., is reportedly investing $300 million into Polymarket. Don Jr. is also a member of the Polymarket board of advisors, and 1789 Capital had previously invested around $200 million in the company.

Don Jr.’s $300 Million Investment

The relationship between the White House and prediction market companies has come under fire recently. One of the biggest areas of scrutiny is the president’s son, Don Jr.’s, relationship with multiple prediction market companies.

Don Jr. is not shying away from prediction markets despite the increased scrutiny. Instead, he is using 1789 Capital, an investment firm he partnered with in 2024, to invest $300 million in Polymarket.

The large investment represents almost a third of the $1 billion funding round. It also makes 1789 Capital one of the largest equity holders in Polymarket.

Kalshi’s $1 Billion Funding Round

Polymarket’s $1 billion funding round comes months after Kalshi had a similar investment push. In May, Kalshi had its own $1 billion funding round that included major firms such as:

• ARK Invest
• Morgan Stanley
• Paradigm
• IVP
• Andreessen Horowitz
• Sequoia Capital

Don Jr. and his firm were not major investors in Kalshi this spring. However, the president’s son has invested in Kalshi and is a member of the prediction market’s board.

How This Impacts Players

Prediction markets like Polymarket face an uncertain regulatory future after a recent ruling from the Ninth Circuit Court. However, this major investment by Don Jr. shows that the president’s son will continue to support the practice. Users can rest easier knowing that the White House will continue to fight for prediction markets for the foreseeable future.

GamblingNerd Take

Competition is always good news for consumers, as it forces companies to offer better bonuses and player-friendly fees. The recent round of investments should help Polymarket continue to grow and maintain its status as the biggest rival to Kalshi. The money will also be helpful with tough legal battles on the horizon for prediction markets.
