Prediction market platform Polymarket is reportedly in discussions with investors to secure an additional $400 million in capital. This funding round is expected to value the company at $15 billion.
The potential raise underscores a significant influx of institutional investment into the predictions market. This follows a previous $600 million investment in Polymarket by Intercontinental Exchange (ICE) in late March. Polymarket is reportedly seeking strategic investors in addition to ICE, with the total funding potentially reaching $1 billion.
Prediction markets have seen explosive growth, particularly around the 2024 US election, now consistently achieving over $10 billion in monthly trading volume. These markets cover a wide array of topics, from sports and political elections to financial results and cultural events.

This surge has attracted major players from Wall Street. Nasdaq MRX has filed to offer binary-style contracts on the Nasdaq-100 index. Cboe Global Markets is launching its own prediction market-style offering, and CME Group has partnered with FanDuel for non-finance market betting. TradFi firms Charles Schwab and Citadel Securities are also reportedly exploring entry into this market.
However, the burgeoning market faces ongoing regulatory challenges. Platforms like Kalshi are involved in legal battles, including allegations of insider trading and market manipulation, with a court having previously blocked Kalshi from operating in Nevada.
