Singapore’s DayOne Accelerates Growth with US$4.5 Billion Raise 

DayOne Data Centers, a Singapore-based digital infrastructure developer, closed a US$4.5 billion Series C financing round, one of the largest recent private capital raises in the global data center sector. The round was led by existing investors Coatue and Hillhouse, which are now the company’s two largest shareholders, with participation from new investors including Indonesia Investment Authority (INA) and Achi Capital Partners. Since launching in 2022, DayOne has secured more than 1.5 GW of booked capacity across Asia Pacific and Europe and plans to use the new capital to accelerate expansion in Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong, Finland, and Spain.

The financing announcement follows a series of major infrastructure and energy milestones. In Malaysia, DayOne signed renewable energy agreements with Tenaga Nasional Berhad (TNB) subsidiaries covering approximately 1.5 GWp of solar generation capacity and 2.2 GWh of battery energy storage under Malaysia’s Corporate Renewable Energy Supply Scheme (CRESS). Combined with a previous 500 MW renewable energy agreement signed in 2025, DayOne has now secured more than 1 GW of renewable energy supply in Malaysia to support its growing hyperscale and AI-focused data center operations.

Earlier this year, DayOne also signed Indonesia’s largest long-term data center power purchase agreement, securing approximately 511 MVA, equivalent to about 450 MW of grid capacity, for its new Kabil Industrial Tech Park campus in Batam. The development expands DayOne’s presence beyond its existing Nongsa Digital Park operations and supports the company’s SIJORI strategy linking Singapore, Johor, and Batam into an integrated regional digital infrastructure platform. Together, the financing, renewable energy commitments, and power agreements position DayOne to support rapidly growing demand for cloud and AI computing infrastructure across Southeast Asia and Europe.

“Today’s signing marks an important milestone in how we scale digital infrastructure responsibly. As demand for AI and cloud infrastructure accelerates, securing long-term access to renewable energy is critical,” said Jamie Khoo, Chief Executive Officer of DayOne.
