Polymarket Raises $400 Million After ICE Backing: Why Capital Is Betting Heavily on Prediction Markets

TradingKey – Polymarket’s valuation rises to $15 billion, demonstrating the strong potential of prediction markets and gaining significant favor from capital.

On April 20, according to a report by The Information, Polymarket, the world’s largest decentralized prediction market platform, plans to raise $400 million at a $15 billion valuation and is currently in talks with potential investors. If successful, this will be Polymarket’s second financing round this year. Last month, Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange (NYSE), committed to investing up to $1.6 billion in Polymarket, having already completed a $600 million strategic investment.

Since its inception in 2020, Polymarket has grown from an obscure platform into a leader in prediction markets. To date, it has secured seven rounds of financing, with its valuation steadily climbing as follows:

The success of Polymarket also signifies that prediction markets have evolved from a niche sector into a significant component of the global financial system that cannot be ignored. Its growth is rapid, and the market scale continues to expand. According to the latest data, the nominal trading volume of the global prediction market reached $25.7 billion in March 2026, a 10.6% increase from February. Bernstein predicts that the total volume of prediction markets for the full year 2026 could reach $240 billion, representing a growth of more than 3.7 times compared to 2025.

To date, prediction markets have attracted a massive influx of institutions, including CME, Cboe, Charles Schwab, Interactive Brokers, Robinhood ( HOOD ), Binance ( BNB ), and others. These institutions and capital entities are betting on prediction markets to capture ‘three core benefits,’ including: obtaining ‘Alpha signals,’ risk hedging, and capturing AI trading and liquidity dividends.
