DayOne Data Centers closes Series C at $4.5B final close
What's the deal? DayOne Data Centers, a Singapore-headquartered digital infrastructure platform, has closed its Series C equity financing at $4.5 billion. The round was led by existing investors Coatue and Hillhouse — now the company's two largest shareholders — with new backers including the Indonesia Investment AuthorityDealroom has a profile for this one.

Founded in 2022, DayOne develops and operates data centres across Asia Pacific and Europe. It has secured more than 1.5GW of total capacity bookings, making it one of the largest and fastest-growing international digital infrastructure platforms.
Why now? Demand for AI-ready data centre capacity is surging globally, and DayOne is racing to meet it. The company plans to use the funds to accelerate expansion across Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong SAR, Finland, and Spain.
DayOne said it may pursue additional equity and debt financing in both private and public markets, hinting at a potential future listing.
What could go wrong? Data centre buildouts are capital-intensive and depend on securing power, land, and regulatory approvals in each market. Expanding across eight countries simultaneously raises execution risk. Competition is also fierce: hyperscalers are increasingly building their own capacity, and rival operators are raising similarly massive war chests.
Energy constraints pose another challenge. Securing 1.5GW of power — roughly the output of a large nuclear plant — across multiple jurisdictions is no small feat, especially as governments tighten rules around data centre energy consumption.
The signal: The involvement of the Indonesia Investment Authority — a sovereign wealth fund — alongside Coatue and Hillhouse signals that AI infrastructure is now attracting the kind of long-horizon, state-backed capital typically reserved for traditional energy and transport megaprojects. With 1.5GW of capacity bookings locked in just three years, DayOne's trajectory also highlights how quickly the data centre sector is consolidating around a handful of well-capitalised platforms capable of operating at scale across multiple jurisdictions simultaneously.
