Nscale Grabs $790M for Norway AI Hub After OpenAI Exit

A UK AI startup has just secured $790 million in fresh debt financing for what is now Norway’s largest AI data centre project. But the real story here goes far beyond the money. OpenAI was supposed to be the anchor tenant at this Arctic site. Microsoft quietly stepped in and took that seat instead.

What the $790M Financing Package Actually Covers

Nscale, the London-based AI infrastructure company backed by Nvidia, announced the financing on May 11, 2026. The committed funding comes from a strong consortium of European banks including ABN AMRO, DNB, Eksfin, Nordea, and SEB.

The money is earmarked for the continued buildout of Nscale’s AI data centre in Kvandal, just outside Narvik in northern Norway. The site is planned to reach 230 megawatts of capacity, making it the single largest AI infrastructure investment in Norway’s history.

But that is not the ceiling. Nscale has also locked in a provision for an additional $790 million through what is known as an accordion feature. That structure allows the company to access extra funding without renegotiating loan terms, and it is tied specifically to a planned 115-megawatt expansion at the same Narvik site.

If both tranches are fully deployed, Nscale would be committing close to $1.6 billion in debt capacity to this single Norwegian project.

Nscale Narvik Norway AI data centre Microsoft financing deal

Microsoft Steps In Where OpenAI Left the Room

The Narvik site was originally built around OpenAI’s European ambitions. In July 2025, OpenAI, Nscale, and industrial group Aker jointly announced Stargate Norway, which was positioned as OpenAI’s first European data centre and the flagship location under its “OpenAI for Countries” programme. The project targeted 100,000 Nvidia GPUs online by the end of 2026.

OpenAI had reportedly wanted to lease roughly half of the Narvik facility’s 230-megawatt capacity, describing itself as the “initial offtaker” at the site. But the two companies never reached a final agreement.

Microsoft moved swiftly. The tech giant has now signed a deal to rent 30,000 Nvidia Vera Rubin GPUs from Nscale at the Narvik campus, with delivery planned for 2027.

This new arrangement builds on a multi-billion-dollar prior commitment Microsoft had already made at the same site, making it the company’s only confirmed major tenant there. Jon Tinter, president of business development and ventures at Microsoft, said the Narvik expansion “helps ensure Microsoft customers have access to the advanced AI infrastructure they need as demand continues to grow across Europe.”

OpenAI’s Quiet Retreat from Its European Stargate Dream

The Narvik situation is not a one-off. It is part of a pattern that has been quietly unfolding across the continent.

In early April 2026, OpenAI paused its Stargate UK data centre project, a site also developed with Nscale, citing high energy costs and the country’s regulatory environment. That project had originally planned for up to 31,000 GPUs at a facility in northern England.

Bloomberg reported that OpenAI told investors in February 2026 it was targeting roughly $600 billion in total compute spend by 2030, down sharply from a $1.4 trillion figure it had previously signalled. Rather than securing capacity directly from Nscale, OpenAI has indicated it intends to access Norwegian compute through its existing arrangement with Microsoft Azure instead.

Here is how the Stargate Norway story unfolded, month by month:

• July 2025: OpenAI, Nscale, and Aker announce Stargate Norway targeting 100,000 Nvidia GPUs
• April 2026: OpenAI and Nscale fail to finalise lease terms for Narvik capacity
• April 2026: Microsoft steps in and agrees to rent 30,000 Nvidia Rubin GPUs at the site
• April 2026: OpenAI pauses its UK Stargate project over energy cost and regulatory concerns
• May 2026: Nscale secures $790M in fresh debt financing with Microsoft as sole Narvik tenant

This marks the second Stargate-branded site that Microsoft has absorbed from OpenAI within a matter of weeks. The irony is striking. OpenAI had pushed publicly to reduce its reliance on Microsoft infrastructure. Yet every site it steps away from strengthens Microsoft’s own position across Europe’s compute landscape, producing the exact opposite of what OpenAI intended.

Why Narvik Is Attracting Global AI Investment

There is a clear reason serious capital keeps flowing into this corner of the Arctic Circle.

The Kvandal site near Narvik sits in a region with abundant hydropower, a cold natural climate, and local electricity prices well below the European average. Those three factors carry enormous weight when you are running tens of thousands of power-hungry Nvidia GPUs continuously.

Narvik’s energy advantage is not accidental. It is Norway’s industrial heritage being repurposed for the digital economy, and it is working.

The facility is designed with closed-loop, direct-to-chip liquid cooling for maximum efficiency. Waste heat from the GPU systems is planned to be redirected to benefit low-carbon enterprises in the surrounding region, a thoughtful approach that is still rare in large-scale data centre development.

Nscale is not stopping at the Narvik campus either. The company is also working on a separate 250-megawatt data centre project in Korgen, near Narvik, and has purchased land in additional Norwegian locations including Fauske and Skien, signalling a long-term commitment to the country as a strategic AI hub.

Nscale’s Rise and What the Numbers Actually Show

It is worth stepping back to understand just how fast Nscale has scaled.

The company launched from stealth in May 2024. What followed has been one of the most aggressive capital accumulation stories in European tech history:

• Late 2024: $155 million Series A led by Sandton Capital Partners
• September 2025: $1.1 billion Series B led by Aker ASA
• February 2026: $1.4 billion Delayed Draw Term Loan backed by GPUs
• March 2026: $2 billion Series C at a $14.6 billion valuation, led by Aker and 8090 Industries
• May 2026: $790 million in new debt financing for the Narvik buildout

The March 2026 Series C was described at the time as the largest of its kind in European history, backed by Nvidia, Citadel, Dell, Jane Street, and Point72 among others. Around the same time, former Meta COO Sheryl Sandberg, former UK Deputy Prime Minister Nick Clegg, and former Yahoo president Susan Decker all joined Nscale’s board, bringing serious governance firepower to a company that is moving at startup speed but operating at hyperscaler scale.

Beyond Norway, Nscale is also rapidly expanding its Microsoft partnership to Portugal. In April 2026, the company announced an expanded collaboration with Microsoft and Start Campus for more than 66,000 Nvidia Rubin GPUs at the Sines data centre campus, starting in late 2027, building on a prior deployment of over 12,600 Blackwell Ultra GPUs at the same site.

CEO Josh Payne summed up the company’s outlook plainly: “Together, these developments position Nscale at the forefront of global AI infrastructure, delivering scalable, high-performance capacity to meet rapidly growing demand for our services.”

From a stealth startup two years ago to a $14.6 billion company anchoring Microsoft’s European compute strategy, Nscale’s story has moved fast and is still accelerating. The pivot from OpenAI to Microsoft at Narvik may look like a twist, but for Nscale it underscores a harder truth: in the AI infrastructure race, the tenant does not define the asset. Northern Norway’s energy, climate, and sheer capacity do. And right now, every major player in the AI industry wants a piece of what Narvik is building. The question worth watching is whether Nscale can match its fundraising speed with delivery on the ground.
