DayOne Data Centers has raised more than $2 billion in a Series C equity round, underscoring surging investor appetite for hyperscale infrastructure as artificial intelligence and cloud demand accelerates globally.
The Singapore-headquartered operator said the financing is among the largest private capital raises in the data centre sector to date. The round was led by existing investor Coatue, with participation from new backers including the Indonesia Investment Authority, the country’s sovereign wealth fund. DayOne said the Series C round was priced at a 100% premium to its previous round.
The latest raise comes after DayOne secured a combined $1.9 billion across its Series A and B rounds in 2024, and lined up as much as 1 billion euros ($1.1 billion) in mezzanine financing from Brookfield and a sovereign investor in 2025.
Proceeds from the Series C will be used to accelerate expansion across Europe and the Asia Pacific. DayOne plans to advance its Finland business, anchored by large hyperscale campuses in Lahti and Kouvola, as part of its broader regional strategy. In Asia-Pacific, the company is scaling capacity across Singapore, Johor, and Indonesia’s Batam island—while pushing further into markets including Thailand, Japan, and Hong Kong.
The company said the investments will support delivery against secured customer commitments of about 1 gigawatt of capacity.
Chief executive officer Jamie Khoo said customers are increasingly seeking partners that can deliver AI-ready infrastructure at scale across multiple regions, with speed and sustainability. “This new capital further strengthens our ability to execute against our secured development pipeline and support the long-term needs of the world’s technology leaders,” she said.
