Polymarket Raises $1 Billion as Trump Jr.’s Firm Leads $21 Billion Valuation — National File

Polymarket plans to raise $1 billion in a new round that would give the prediction-market platform a $21 billion post-money valuation, Bloomberg reported.

1789 Capital, Donald Trump Jr.’s investment firm, is leading the reported round and plans to contribute $300 million. A 1789 spokeswoman confirmed the core terms to the New York Times, which put Polymarket’s previous valuation at $15 billion.

Trump Jr. is a 1789 Capital partner and a Polymarket adviser. The company confirmed both roles in its 2025 announcement of 1789’s first strategic investment, whose terms it did not disclose.

The reported $21 billion figure would lift Polymarket’s private valuation by 40 percent. It would also deepen 1789’s stake in a platform directly affected by federal policy toward prediction markets.

The Times reported that Trump administration officials have backed the sector while challenging state efforts to regulate it. The president’s son now serves both as a partner at the firm leading this raise and as an adviser to the company receiving the cash.
