The parent company of the New York Stock Exchange made a $600 million transaction into the blockchain prediction market platform, Polymarket.
ICE first invested $1 billion into Polymarket back in October 2025, and this latest injection brings its total commitment to nearly $2 billion. Combined with plans to purchase up to $40 million of existing Polymarket shares, ICE has now fulfilled its entire investment agreement with the platform. The final valuation won't be disclosed until Polymarket wraps its broader fundraising round which, according to the Wall Street Journal, is targeting around $20 billion.
A Rival prediction platform Kalshi just raised over $1 billion at a $22 billion valuation, led by Coatue Management, and is already generating an estimated $1.5 billion in annual revenue. Prediction market monthly volumes have grown 130-fold since early 2024. Open interest crossed $1 billion for the first time in February. This isn't a niche corner of crypto anymore.
What Does ICe Want With Polymarket
In February, ICE launched its "Polymarket Signals and Sentiment" tool, making itself the exclusive institutional distributor of Polymarket's crowd-sourced probability data. Hedge funds and trading desks can now pull real-time prediction market signals directly into their workflows through ICE's infrastructure and set up the same pipes that carry NYSE data.
The logic is simple and straightforward, since polymarket's traders have always priced macro and political events ahead of traditional markets. That kind of leading indicator is worth far more than a $2 billion ticket to a prediction market.
Polymarket itself has had a turbulent journey to get here. The FBI raided the founder, Shayne Coplan's New York apartment in November 2024 over alleged U.S. access violations. The DOJ and CFTC dropped both investigations without charges by July 2025. By December, Polymarket had relaunched in the U.S. under full CFTC oversight.
From a federal raid to a near-$20 billion valuation backed by Wall Street's biggest exchange operator in under 18 months. The question now isn't whether prediction markets are legitimate. ICE already answered that. It's what they are planning to do with the data.
