DayOne Data Centers Raises US$2bn to Boost Hyperscale Growth

DayOne Data Centers (DayOne) has secured more than US$2bn in Series C equity financing as it accelerates the expansion of its hyperscale data centre platform across Europe and Asia-Pacific.

Headquartered in Singapore, DayOne operates as an independent hyperscale data centre developer and owner.

The financing represents one of the largest private capital raises in the data centre sector and further strengthens the company’s ability to deliver large-scale, high-density infrastructure for cloud and AI workloads.

The Series C round was led by existing investor Coatue and supported by new and returning institutions including the Indonesia Investment Authority, Indonesia’s sovereign wealth fund.

The transaction follows US$1.9bn raised across Series A and Series B rounds in 2024 and a mezzanine debt facility of up to €1bn (US$1.17bn) secured in 2025 from Brookfield and a sovereign investor.

Global capital backing a multi-region strategy

The latest funding round attracted a broad group of investors from the United States, Europe and Asia-Pacific.

DayOne has said the diversified shareholder base aligns closely with its international development strategy and strengthens its ability to execute projects across multiple regions.

Series C was priced at a 100% premium to the prior round, reflecting investor confidence in the platform’s growth trajectory and execution capabilities.

The capital will be used to accelerate development across DayOne’s secured pipeline and support its expansion into priority hyperscale markets.

In Europe, the financing is expected to advance DayOne’s Finland platform, anchored by large hyperscale campuses in Lahti and Kouvola. These sites form the foundation of the company’s broader European strategy, offering access to low-carbon power, established grid infrastructure and scalable land positions.

In Asia-Pacific, the proceeds will support further scale-out across the SIJORI region – Singapore, Johor and the Riau Islands – as well as continued development in Thailand, Japan and Hong Kong.

The focus is on delivering high-density, AI-ready capacity at speed while maintaining sustainability objectives.

Supporting a growing hyperscale pipeline

DayOne said the investments will strengthen delivery against secured customer commitments of approximately 1GW.

The company describes this as one of the fastest growth trajectories among next-generation hyperscale infrastructure platforms.

Jamie Khoo, CEO of DayOne, says: “This investment reflects deep confidence in DayOne’s platform quality and long-term growth trajectory. 

“As global demand for AI and cloud infrastructure accelerates, customers are increasingly looking for partners that can deliver at scale, with speed and sustainability across multiple regions. 

“This new capital further strengthens our ability to expand our European and Asia-Pacific platforms, execute against our secured development pipeline and deliver high-performance, AI-ready capacity that supports the long-term needs of the world’s technology leaders.”

The company’s portfolio is designed around the requirements of advanced compute, with facilities capable of supporting high rack densities and next-generation workloads.

Designs incorporate liquid-cooling readiness, prefabricated construction models and renewable or low-carbon power pathways, supported by utility and government partnerships.

Investor confidence in execution and scale

For Coatue, the Series C investment reflects continued confidence in DayOne’s ability to deliver at pace across multiple markets.

Robert Yin, General Partner and Head of AI Infrastructure at Coatue, says: “DayOne continues to rapidly expand its data centre platform in APAC and Europe, exceeding our expectations and delivering on strong demand for AI and hyperscale infrastructure. We’re excited to support DayOne’s next phase of global development with this financing.”

The Indonesia Investment Authority has been a partner of DayOne since the establishment of their joint venture in Indonesia in 2023. Its participation in the Series C marks a deeper commitment at the global platform level.

Ridha Wirakusumah, CEO of the Indonesia Investment Authority (INA), says: “INA’s partnership with DayOne began with a shared conviction that digital infrastructure is a critical enabler of long-term economic competitiveness. 

“Following the establishment of our joint venture in Indonesia in 2023, this Series C investment represents a deepening of our partnership at the global platform level, reflecting confidence in DayOne’s execution capabilities and its ability to scale high-quality hyperscale infrastructure across markets and underscoring INA’s role as a long-term, strategic investor supporting world-class platforms that deliver sustainable returns.”

With fresh capital in place, DayOne is advancing development across its core regions while maintaining a focus on speed to market, resilience and the evolving demands of hyperscale customers.
