ICE completes $1.6B Polymarket investment as regulation tightens

Intercontinental Exchange (ICE) has completed its Polymarket funding, bringing total support to $1.6 billion. ICE previously pledged up to $2 billion in October 2025, with an initial $1 billion investment; the latest $600 million fulfills the remaining obligation. ICE also plans to buy up to $40 million of Polymarket securities from existing holders, linking the payment to Polymarket’s equity capital fundraising. The funding arrives amid rising regulatory scrutiny in Washington and several states. A Massachusetts lawmaker has banned staff from trading on prediction market platforms such as Polymarket and Kalshi due to insider-trading concerns. Meanwhile, lawmakers are advancing the bipartisan PREDICT Act to extend similar restrictions to members of Congress and senior officials (and their families), with additional proposals targeting sports and war-related prediction markets. For traders, the key setup is two-sided: Polymarket’s new capital and institutional validation can lift sentiment around event-based prediction markets, while tightening compliance rules could limit market access and future growth. Rival platform Kalshi recently raised $1 billion at a $22 billion valuation after election-contract offerings cleared following a CFTC-related court process.
