Nscale, a London-based artificial intelligence infrastructure company, has secured a $900 million line of credit to accelerate the construction of data centres across the United States, Europe and Asia-Pacific.
The facility is a revolving credit line, meaning Nscale can draw on the money, repay it and borrow again as needed, rather than taking a single fixed sum.
That flexibility is designed to let the company fund construction across several regions at once as demand for AI computing continues to outstrip supply.
The deal was syndicated across twelve major banks, including JP Morgan, Goldman Sachs, Morgan Stanley, RBC Capital Markets, Bank of America and Deutsche Bank.
The founder and chief executive, Josh Payne, said the lineup of lenders reflected institutional confidence in the company's platform, capital structure and team.
Nscale operates a network of data centres in Norway, the United Kingdom and the United States, with partner-run sites in Portugal, Iceland and further locations across Europe and North America.
Customers reserve capacity by booking graphics processing units, the specialised chips that handle the vast number of calculations required to train and run AI models.
The company sells that capacity to model builders including Microsoft and OpenAI.
The credit line is the latest in a rapid sequence of fundraising.
Nscale raised a $1.1 billion Series B round in early 2025, followed by a $2 billion Series C in March 2026 that valued the company at $14.6 billion.
That round drew backing from Nvidia, the dominant AI chipmaker, alongside Dell Technologies and the Norwegian investor Aker.
The company also closed a $1.4 billion term loan in February and $790 million in project financing for its Norwegian campus in May.
Including the new facility, Nscale has now raised more than $6 billion in combined debt and equity.
The Norwegian operations run on renewable power, drawing on the hydroelectric and wind resources that once attracted Bitcoin miners to the region.
Nscale itself has roots in that world, having been spun out of the Bitcoin miner Arkon Energy before formally taking shape in 2024.
Its expansion has been closely tied to Nvidia's hardware roadmap.
In a recent move the company enlarged a collaboration with Microsoft and the operator Start Campus to deploy more than 66,000 of Nvidia's next-generation Rubin GPUs from late 2027.
The reliance on debt marks a wider shift in how AI capacity is being funded.
Increasingly, GPU infrastructure is financed like heavy industrial plant, through investment-grade borrowing from mainstream banks, rather than through venture capital alone.
For Nscale, the revolving facility converts that lender confidence into standing firepower it can deploy as its order book grows.
