Singapore-based data center developer and operator DayOne Data Centers has completed the final closing of its Series C equity financing at $4.5 billion, in one of the largest fundraises by a data centre company in the region.

In a statement on Friday, DayOne said the round was led by existing investors Coatue and Hillhouse, now DayOne’s two largest shareholders, with participation from new investors including the Indonesia Investment Authority and Achi Capital Partners.

The proceeds are expected to accelerate DayOne’s expansion across Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong, Finland, and Spain. DayOne said it may also consider additional equity and debt financing options in private and public markets subject to funding needs and market conditions.

Since its founding in 2022, DayOne has secured more than 1.5 GW of total bookings for capacity across Asia Pacific and Europe, making it one of the largest and fastest-growing international digital infrastructure platforms. The company develops and operates AI-ready data center campuses for global hyperscalers and enterprises.
