Polymarket CEO Shayne Coplan said that Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, is one of Polymarket's biggest shareholders and is thinking hard about onchain equity. The statement, posted on X on October 7, 2026, highlights a significant institutional tie between the regulated exchange giant and the crypto-native prediction market platform.

ICE's status as a major shareholder signals deep institutional validation for Polymarket and could accelerate the NYSE parent's own moves into onchain and event-contract markets.
