NYSE's parent company invests $600m more in Polymarket

The parent company of the New York Stock Exchange has doubled down on its investment push into the prediction market space, with the company dropping another $600-million tranche of capital into Polymarket, one of the leaders in the sector. This is not the first time the company has backed the platform, having previously invested $2bn in Polymarket in October 2025, and signaling a strong commitment to the sector and confidence in its future. Despite a litany of regulatory and legislative challenges, InterContinental Exchange (ICE) retains its optimistic outlook for the sector. ICE has confirmed that it does not expect the deal to have a material impact on its financial results or capital returns. In a statement, the company outlined the motivation behind the move: Intercontinental Exchange, one of the world’s leading providers of financial market technology and data powering global capital markets, announced that, as part of its previously announced investment arrangement with Polymarket, ICE has completed a new $600 million direct cash investment in Polymarket, which is part of an equity capital fundraising by Polymarket. Polymarket’s exact valuation is still undisclosed, as the company is still conducting a funding round, but it is possible to see the metric pushed past the $20-billion mark, double the amount the valuation stood at when ICE first invested in the prediction market platform. Backing of such magnitude is impressive, especially given that Kalshi is considered to be the leader in the United States, with Polymarket still bringing its operations online in the country. Kalshi is not falling much behind, however, and the company is reportedly valued at $22bn following a $1bn funding round, led by Coatue Management.
