Shares of Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, climbed more than 1% following news that the firm has acquired a $2 billion stake in the prediction markets platform Polymarket. The investment places Polymarket’s valuation at roughly $8 billion, according to a joint statement from both companies.

ICE Chairman and CEO Jeffrey Sprecher said in a press release that the partnership will open new frontiers across financial and data-driven markets. “There are opportunities across markets that ICE, together with Polymarket, can uniquely serve, and we are excited about where this investment can take us,” Sprecher noted.

The move reflects the growing mainstream adoption of prediction markets, a niche once limited to enthusiasts but now rapidly expanding. Polymarket’s competitor, Kalshi, has also experienced a sharp rise in trading volume, driven largely by the popularity of its sports-related contracts. Analysts at Piper Sandler project that the global prediction market industry could generate as much as $8 billion in annual revenue by 2030, as it continues to capture market share from the sports betting sector.

Earlier this year, Polymarket received an investment from 1789 Capital, a firm supported by Donald Trump Jr. The company also recently received regulatory approval to operate in the United States, marking a major milestone in its expansion efforts.

Polymarket’s founder and CEO, Shayne Coplan, said in a statement that combining ICE’s institutional strength and reputation with Polymarket’s innovative and consumer-focused approach will enable them to create “world-class products for the modern investor.”

The deal, which was first reported by The Wall Street Journal, underscores how established financial institutions are increasingly embracing emerging platforms that merge technology, market data, and real-world forecasting. As traditional finance continues to intersect with decentralized innovation, ICE’s investment signals growing confidence in prediction markets as a legitimate asset class and a key component of the future financial landscape.
