Summary:
  • 1789 Capital is leading a new financing for Polymarket at a $21 billion post-money valuation.
  • People familiar with the plan say Polymarket will raise $1 billion.
  • Bloomberg previously reported early-month talks above $20 billion and an April round at $15 billion with D.E. Shaw and G Squared joining.

The round and the numbers

1789 Capital is heading a fresh investment into Polymarket that sets the prediction-markets platform's valuation at $21 billion after the deal. According to people with knowledge of the matter, the company will raise $1 billion. Bloomberg reported earlier this month that Polymarket was in initial discussions to secure funding at a valuation topping $20 billion. A Polymarket spokesperson declined to comment.

Recent investor moves

Polymarket closed a round in April at a $15 billion valuation, adding D.E. Shaw and venture firm G Squared as new backers, per prior Bloomberg reporting. The new financing adds to signals that prediction markets are expanding quickly.

Industry context and connections

Prediction platforms like Polymarket let users wager on outcomes across areas such as sports and elections, and this deal is another marker of that sector's rapid growth. Despite that momentum, Polymarket has lagged its primary rival, Kalshi, over the course of this year because of operational and legal challenges. In May, Kalshi raised funds at a $22 billion valuation, and Donald Trump Jr., a partner at 1789, advises both Polymarket and Kalshi.
