Polymarket is in talks to raise $1 billion at a valuation above $20 billion, a funding round led by 1789 Capital, the investment firm co-founded by Donald Trump Jr. To put the trajectory in perspective: the prediction market platform was valued at roughly $300 million not long ago.
The round places Polymarket in rarefied air among crypto-adjacent startups, rivaling the scale of funding typically reserved for late-stage fintech giants.
From advisory board seat to lead investor
1789 Capital’s relationship with Polymarket isn’t new. The firm invested in the platform back in August 2025, reportedly deploying a sum in the double-digit millions. That initial bet came shortly after a round that valued the company at around $300 million, meaning 1789 Capital is now sitting on enormous paper gains.
Trump Jr. joined Polymarket’s advisory board following that initial investment.
A valuation rocket ship
The Intercontinental Exchange, the company that owns the New York Stock Exchange, made a substantial investment that helped push Polymarket’s valuation to roughly $8 to $9 billion. ICE’s total commitment has reportedly reached approximately $1.6 billion or more.
By April 2026, the valuation had climbed to $15 billion. Now, the reported valuation stands above $20 billion. Total disclosed funding for the platform has exceeded $2.7 billion.
Kalshi, its primary competitor, raised $1 billion at a $22 billion valuation in May 2026. The two platforms are now valued within a billion dollars of each other.
Why prediction markets became a magnet for capital
Polymarket built its reputation on blockchain-based settlement, using crypto rails for transparency and efficiency. The platform’s explosive growth during recent election cycles demonstrated that demand was real and not merely speculative curiosity, with trading volumes surging during high-profile political events.
