Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange (NYSE), announced that it has added an additional $600 million to its investment in prediction market platform Polymarket, closing a previously announced financing agreement between the two companies.
The new capital comes on top of a billion-dollar investment made by ICE in October. ICE also plans to purchase up to $40 million in additional shares from existing holders, bringing its total commitment to nearly $2 billion. The company said the investment would not materially affect its financial results.
Polymarket operates a marketplace where users trade on the outcomes of real-world events, from elections to the release of economic data. A trader, for example, can buy stocks that pay off if inflation exceeds a specified level. Prices change in real time, reflecting crowd expectations.
ICE’s support gives Polymarket much more than capital. This ties the platform to one of the upcoming names in the global markets. Rival platform Kalshi recently raised over $1 billion at a valuation of $22 billion, roughly double its previous mark. The company already generates an estimated $1.5 billion in annual revenue, highlighting the strong demand for event-driven trading.
Investor interest has grown even as lawmakers question whether prediction markets are vulnerable to manipulation or insider activity. These concerns could shape how regulators treat Polymarket and its peers in the years to come.
Polymarket has taken steps to position itself for this scrutiny. It acquired a licensed exchange and clearing house earlier this year while expanding its political and financial ties. It also recently announced a partnership with Palantir and TWG AI to build a monitoring system aimed at detecting suspicious transactions and manipulation in its sports prediction markets.
ICE’s investment shows that large traditional market operators see the potential in the sector. If prediction markets gain broader approval, they could tie in with stocks and futures, providing another way for traders to express their views on upcoming events.
