DayOne Data Centers Limited (“DayOne”), an independent hyperscale data center platform headquartered in Singapore, announced that it has closed definitive agreements for over US$2 billion in Series C equity financing, marking one of the largest private capital raises in the global data center sector. Coatue, an existing global investor, led the round, which also drew support from prominent institutions including the Indonesia Investment Authority (INA), Indonesia’s sovereign wealth fund.
By attracting a diverse base of international investors, DayOne has strengthened its shareholder profile and enhanced its ability to support expansion across Europe and Asia-Pacific markets. The Series C investment complements the US$1.9 billion raised in Series A and B rounds in 2024, along with the up to €1 billion mezzanine debt facility secured in 2025 from Brookfield and a sovereign investor. Notably, the Series C round was priced at a 100% premium to the previous round.
DayOne plans to deploy the new capital to accelerate its global growth strategy. In Europe, the funds will support the development of DayOne’s Finland platform, including hyperscale campuses in Lahti and Kouvola, forming a cornerstone of its European expansion. Meanwhile, in the Asia-Pacific region, the investment will enable DayOne to expand its footprint across the SIJORI (Singapore–Johor–Riau Islands) region, as well as key markets in Thailand, Japan, and Hong Kong, delivering high-density, AI-ready infrastructure with speed and sustainability.

These strategic investments will also strengthen DayOne’s ability to fulfill approximately 1GW of secured customer commitments, positioning the company among the fastest-growing next-generation hyperscale platforms.
Jamie Khoo, CEO of DayOne, stated: “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.”
Robert Yin, General Partner & Head of AI Infrastructure at Coatue, added: “DayOne continues to rapidly expand its data center 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.”

Ridha Wirakusumah, CEO of INA, commented: “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.”
DayOne’s next-generation infrastructure portfolio integrates high-density liquid-cooling designs, renewable and low-carbon power pathways, and rapid-deployment prefabricated models. With strong utility and government partnerships, the company is poised to deliver scalable, resilient infrastructure across markets. The Series C financing solidifies DayOne’s position as a leading hyperscale data center platform in Asia-Pacific and Europe, catering to the long-term needs of global technology leaders.
