I Squared Capital is nearing $10 billion in commitments for its flagship infrastructure fund, signaling strong investor appetite for critical infrastructure assets. The firm expects to secure roughly two-thirds of its $15 billion target by month's end, less than nine months after launching the vehicle.

This fundraising surge reflects broader industry momentum, with private infrastructure funds raising a record $208 billion globally in 2025. Institutional investors are increasingly financing electricity grids, transport networks, and data centers as governments modernize aging systems. Private equity firms have stepped in to fill infrastructure funding gaps.

The rapid progress underscores the growing role of private capital in global infrastructure development. I Squared has already deployed capital from its flagship vehicle, investing in toll road infrastructure in India and a tire recycling business in North America.
