Prediction market platform Polymarket has hit a $21 billion valuation after raising $1 billion in a new funding round led by 1789 Capital, a venture fund co-founded by Donald Trump Jr.
The news of the increased valuation was first reported by Bloomberg, with reports also indicating that 1789 Capital is set to contribute over $300 million after a previous $200 million investment in Polymarket. The latest $21 billion valuation marks a 40% jump compared to the operator’s $15 billion valuation that was reached in April 2026.
Initially, 1789 Capital started investing in Polymarket in 2025, with the relationship aligning with the timeline when Trump Jr. also joined the prediction market’s advisory board as a partner.
Donald Trump Jr. had shared at the time of the appointment:
“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.”
The CEO of Polymarket, Shayne Coplan, had also commented:
“We are proud to formally welcome 1789 Capital as a strategic partner and Donald Trump Jr. to our advisory board as we continue building our platform to reflect real-world sentiment, in real time, for all to see.”
The funding round comes after Intercontinental Exchange, the parent company of the New York Stock Exchange, invested $600 million in Polymarket, bringing its stake to $1.6 billion. Additionally, Intercontinental Exchange is now the biggest shareholder in the company with a 22% stake.
