Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange (NYSE), said it added an additional $600 million to its investment in prediction market platform Polymarket, closing a previously announced financing deal between the two firms.
The new capital comes on top of a $1 billion investment ICE made in October. ICE also plans to buy up to $40 million in additional shares from existing owners, bringing its total commitment close to $2 billion. The company said the investment will not materially affect its financial results.
Polymarket operates a marketplace where users trade the outcome of real-world events, from elections to the release of financial data. For example, a trader can buy stocks that pay off if inflation rises above a certain level. Prices change in real time, reflecting audience expectations.
The support from ICE gives Polymarket more than capital. It ties the platform to one of the up-and-coming names in global markets. Rival platform Kalshi recently raised more than $1 billion at a $22 billion valuation, roughly double its previous mark. The company already generates an estimated $1.5 billion in annual revenue, highlighting strong demand for event-based commerce.
Investor interest has grown, even as lawmakers question whether the prediction markets are vulnerable to manipulation or insider activity. These concerns could shape how regulators treat both Polymarket and its peers in the coming years.
Polymarket has taken steps to position itself for this investigation. It acquired a licensed stock 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 trading and manipulation in its sports prediction markets.
ICE’s investment signals that large, traditional market operators see potential in the sector. If prediction markets gain wider acceptance, they could sit alongside stocks and futures as another way for traders to express views about upcoming events.
