Singapore-based DayOne Data Centers has secured a $2 billion Series C funding round, setting the stage for a global expansion.
This injection of capital comes at a time when AI demand is exploding and traditional data center approaches are struggling to keep pace.
The scale of this funding round reflects something deeper than typical venture capital activity — it signals institutional confidence that the next phase of AI infrastructure will require entirely new approaches to speed, sustainability, and global reach.
The funding was spearheaded by existing investor Coatue, with significant participation from Indonesia’s sovereign wealth fund.
Factory-built approach
What makes this funding round particularly intriguing isn’t just the dollar amount — it’s the radical construction methodology DayOne is pioneering. While traditional data center companies transport materials and assemble facilities on-site, DayOne assembles its facilities from pre-fabricated modules made at a factory. This factory-based approach dramatically accelerates construction timelines and reduces costs compared to conventional methods.
The company claims it can produce up to 2,500 data center modules annually, representing 500 megawatts of capacity. This manufacturing capability could address one of the AI industry’s most pressing bottlenecks: the time it takes to bring new computing capacity online. DayOne’s facilities are specifically optimized for liquid-cooled racks equipped with Nvidia chips, where coolant circulates through racks and absorbs heat from metal plates attached to key components.
The company has also developed custom software systems to manage graphics card racks, including observability tools that monitor system health and hardware usage while detecting potential malfunctions before they cause service disruptions.
Expansion strategy
DayOne’s expansion plans span two continents, with a focus on AI-ready locations. The company’s flagship project involves a massive 24-acre data center campus in Lahti, Finland, being constructed at a cost of €1.2 billion and expected to host 120 megawatts of computing infrastructure at full capacity when it comes online early next year.
The Series C proceeds will fund development across multiple high-growth markets, including Finland’s Lahti and Kouvola campuses, expansion throughout the SIJORI region (Singapore, Johor, and Riau Islands), and continued development in Thailand, Japan, and Hong Kong.
In Singapore, the company is constructing a 20-megawatt facility equipped with advanced fuel cell technology that uses hydrogen and oxygen to produce water and generate electricity while operating at extreme temperatures.
The company has already secured customer commitments totaling approximately one gigawatt of capacity. This represents one of the fastest growth trajectories among next-generation hyperscale infrastructure platforms.
AI infrastructure race
The Series C was priced at a 100 percent premium to the previous round, indicating extremely strong investor confidence in DayOne’s approach and market positioning.
The funding builds upon an impressive capital-raising trajectory, following $1.9 billion raised across Series A and B rounds in 2024, plus a €1 billion mezzanine debt facility secured from Brookfield and a sovereign investor last month. This brings DayOne’s total funding to over $5 billion in just two years.
As AI workloads continue demanding huge amounts of computing power, DayOne’s combination of deployment capabilities, sustainable design, and global positioning could give it plenty of happy days.
At CES 2026, Jensen Huang said Nvidia is scaling full AI systems as reasoning, agents, and physical AI drive exploding compute, power, and memory demand.
