About
Polymarket is a prediction markets platform, founded in 2020 by Shayne Coplan, that lets users trade on the outcome of real-world events such as elections, sports and economic indicators 12. On August 31, 2026, multiple outlets reported that the New York–based company was raising $1 billion in a round led by 1789 Capital at a $21 billion post-money valuation 123. The reporting cited a Wall Street Journal scoop indicating that 1789 Capital — the investment firm where Donald Trump Jr. is a partner — was contributing roughly $300 million of the round 23.
The August 2026 round marks Polymarket’s third major financing of the year, following an April 2026 round at a $15 billion valuation with backing from D.E. Shaw and G Squared, and a $1.6 billion investment from Intercontinental Exchange earlier in 2026 12.
