What happened
Bloomberg and The Wall Street Journal reported on August 31, 2026 that Polymarket was raising $1 billion in a funding round led by 1789 Capital. The round would value the prediction-markets platform at $21 billion post-money, according to the reports. The WSJ described the round as upcoming and attributed the details to people familiar with the matter. Polymarket declined to comment to the WSJ, and the reports were not a Polymarket announcement.
The WSJ headline said Donald Trump Jr.'s fund was boosting its Polymarket investment by around $300 million. Bloomberg's report, which drew on people familiar with the matter and a spokesperson for the firm, put 1789's contribution to the round at about $300 million and said 1789 had previously invested about $200 million. The reports did not name other participants in the round, share terms or a closing date.

Why it matters
A $21 billion post-money figure gives holders of Polymarket shares a fresh reference point for pricing, if the round closes on the reported terms. The reports do not describe the share price or class.
One investor, 1789 Capital, is reported to supply around $300 million of the $1 billion. A large lead with prior exposure can anchor the price, but terms for other investors were not reported.
The WSJ described the round as upcoming and sourced it to people familiar. Until the company confirms, the valuation is a reported figure.
