Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange (NYSE), announced Friday that it has completed a $600 million direct cash investment in prediction market platform Polymarket. The company also indicated it expects to purchase up to $40 million of Polymarket securities from existing holders. This latest transaction builds on a previously announced commitment made in October 2025, when ICE said it would invest up to $2 billion in the platform.
The October 2025 deal was described as one of the largest institutional moves into the prediction market sector. The newest transaction advances that arrangement, though specific terms including the valuation of Polymarket were not disclosed. ICE’s continued investment signals a clear intention to expand its presence in the prediction market space as exchange operators look for new areas of growth.
The investment has drawn attention from figures in the blockchain industry. Aishwary Gupta, global head of business at Polygon Labs, told Cointelegraph that ICE’s move reflects growing institutional interest in onchain market platforms. Gupta noted that Polymarket’s growth on Polygon demonstrates how blockchain infrastructure can support high-frequency, real-time market activity at scale.
The development comes at a time when prediction markets are facing increasing regulatory scrutiny across the United States. At least 11 states are pursuing legal action against prediction market platforms, including Polymarket and competitor Kalshi. The regulatory environment presents a notable challenge for the sector even as institutional investment continues to flow in.
Individual state responses have varied in severity. Nevada has issued a temporary ban on Kalshi, while Arizona filed criminal charges alleging the platform operated an illegal gambling business. Several other states have issued cease-and-desist orders or are actively considering new legislation targeting prediction market operators.
Amid the regulatory pressure, Polymarket has taken steps to address concerns about market integrity. The platform recently updated its rules to more clearly prohibit trading on confidential information, a response to criticism from lawmakers and observers who argue that prediction markets can be vulnerable to insider-style activity. Areas of particular concern include markets centered on politics, sports, and geopolitics.
