The Singapore-headquartered hyperscale platform said the funding round was led by existing investor Coatue and supported by global institutions including the Indonesia Investment Authority (INA).
The fresh capital builds on previous fundraising efforts, with the firm having raised approximately US $1.9 billion across Series A and Series B rounds in 2024, as well as securing an up to €1 billion mezzanine financing facility in 2025. The Series C was priced at a 100 % premium to the prior round, signalling strong investor confidence in DayOne’s growth trajectory.
DayOne said the funding will be used to accelerate its global expansion, with a particular focus on Europe and the Asia-Pacific region. In Europe, proceeds are expected to support development of its hyperscale campuses in Lahti and Kouvola, Finland, which form the foundation of the company’s broader continental strategy.
In Asia-Pacific, capital will back ongoing scale-outs across the SIJORI corridor, encompassing Singapore, Johor (Malaysia) and Batam (Indonesia) and further growth in Thailand, Japan and Hong Kong.
The investment comes as demand for data centre capacity continues to surge globally, driven by growth in cloud computing, AI workloads and digital transformation initiatives.
Hyperscale facilities capable of supporting high-density, AI-ready infrastructure are a key focus for both enterprise and cloud providers, pushing investors to back platforms with extensive development pipelines.
DayOne’s expanded financial firepower should help it deliver on around 1GW of secured customer commitments and execute a broad build-out strategy while navigating tight supply and rising build costs that have challenged the data centre market.
