Polymarket's Private Shares Have Soared 670% in a Year — And More Than 10,000% Since 2020

Polymarket's private-market shares have delivered a staggering return over the past year, with Forge data showing the prediction-market company's secondary-market price has climbed roughly 670% in 12 months and more than 10,700% since its earliest tracked pricing.

Forge's latest data shows Polymarket's Forge Price at $137.70 per share as of Oct. 5, implying a private-market valuation of roughly $14.34 billion. That's a dramatic increase from the company's earliest Forge-tracked data. In 2020, Polymarket was valued at about $18.6 million, with its shares priced as high as $1.27.

At today's Forge Price, Polymarket's shares have gained approximately 10,743% from that level, underscoring the extraordinary rerating the prediction-market platform has undergone in just a few years.

The company has also undergone an extraordinary rerating over just the past year. In August 2025, Polymarket raised capital at a $1.2 billion valuation, with a reported share price of $17.89. The current Forge Price represents an increase of roughly 670% from that level.

That surge has come as prediction markets have moved from a niche corner of crypto into a much larger financial-market opportunity spanning politics, sports, economics and other real-world events.

Secondary Market Trails Latest $21B Valuation

The latest private-market pricing also highlights a growing gap between Polymarket's secondary-market value and the valuation investors have recently assigned to the company in primary financing.

In August, Polymarket reportedly raised another $1 billion at a $21 billion valuation, with 1789 Capital, the venture capital firm linked to Donald Trump Jr. leading the round and contributing roughly $300 million.

That $21 billion valuation is about 46% above Forge's current $14.34 billion implied valuation.

Forge's own funding data, however, still lists Polymarket's March 2026 Series E at a $15 billion post-money valuation, when the company raised $1 billion at $144.08 per share. The current Forge Price of $137.70 is about 4.4% below that per-share funding price.

The discrepancy illustrates an important feature of private markets: secondary pricing can move independently of headline valuations attached to new primary financing rounds.

Prediction Markets Become a Bigger Bet

The valuation surge comes as Polymarket pushes further into mainstream finance. Reuters reported in June that Polymarket's annualized revenue had surpassed $1 billion, highlighting the rapid growth of prediction markets and the company's expansion into the U.S. market.

The company has also attracted major institutional backing. Intercontinental Exchange, the parent of the New York Stock Exchange, invested $600 million in Polymarket in March as part of a previously announced plan to invest as much as $2 billion in the company.

That institutional interest has helped transform Polymarket's private-market story from a crypto startup bet into a broader wager on prediction markets as a new financial product.

Polymarket's private-market trajectory reflects how quickly investor expectations have shifted around prediction markets. With its Forge valuation still below the company's reported $21 billion funding valuation, the secondary market is now pricing in the possibility of another significant step up - even after a more than 100-fold increase from its earliest tracked levels.
