DayOne Data Centers Limited announced it has entered into definitive agreements for more than $2.0 billion in Series C equity financing, a fundraising total the company described as one of the largest private capital raises in the data center sector. The Singapore-headquartered platform said the new capital is intended to accelerate development of next-generation, AI-ready digital infrastructure across key markets in Asia-Pacific and Europe.
The company said the round was led by existing investor Coatue and supported by additional institutions, including the Indonesia Investment Authority (INA), Indonesia’s sovereign wealth fund. DayOne said the Series C attracted a broad base of investors spanning the United States, Europe, and Asia-Pacific, further diversifying its shareholder base and strengthening its capacity to expand into international markets.
DayOne positioned the financing as the next step in a multi-year capital buildout. The company said it previously raised an aggregate $1.9 billion across Series A and Series B equity rounds in 2024. It also cited an up to €1 billion mezzanine debt facility secured in 2025 from Brookfield and a sovereign investor. DayOne added that the Series C was priced at a 100% premium to the prior round.
The proceeds are expected to fund the next phase of global development, with a focus on scaling large hyperscale campuses and expanding the company’s ability to deliver high-density capacity. In Europe, DayOne said the financing will advance its Finland platform, centered on major campuses in Lahti and Kouvola, which it described as a foundation for its broader European strategy. In Asia-Pacific, the company said capital will support continued scale-out in the SIJORI region—Singapore, Johor, and Indonesia’s Riau Islands, including Batam—alongside investment in Thailand, Japan, and Hong Kong.
DayOne said the buildout is designed to strengthen delivery against approximately 1 gigawatt of secured customer commitments, which it characterized as evidence of one of the fastest growth trajectories among next-generation hyperscale infrastructure platforms. The company framed the timing around accelerating demand for AI and cloud infrastructure, with customers prioritizing partners that can execute quickly across multiple regions while meeting sustainability expectations.
Operationally, DayOne said its portfolio is engineered for next-generation compute requirements. The company highlighted high-density, liquid-cooling–enabled designs, renewable and low-carbon power pathways, and rapid-deployment prefabricated models, supported by utility and government partnerships. DayOne said these capabilities position it to deliver scalable, resilient infrastructure across markets as hyperscalers and large enterprises expand compute footprints.
DayOne describes itself as an independent, next-generation data center developer and operator focused on reliable, cost-effective, and quickly scalable solutions for hyperscalers and large enterprises. Its developments span Singapore, Johor (Malaysia), Batam (Indonesia), Greater Bangkok, Tokyo, Hong Kong, and Finland.
