Europe’s Cloud Boom Was Two UK Landlords and Debt

European cloud firms raised about €5.9 billion in the first half of 2026, and more than 99 percent of it went to two UK data-centre companies. Nscale booked $4.19 billion across three deals. Pure Data Centres booked $2.7 billion against campuses and a corporate line.

The other four names on the same list sit in Germany, the Czech Republic and Lithuania. Their disclosed cheques were $6 million, €4.1 million and $2 million, plus one unnamed round that still made a unicorn.

Two UK Landlords Took More Than 99 Percent

The period covered eight transactions, one of them with no published amount. Debt did the heavy lifting, which is how GPU halls and leased campuses get built. Equity still showed up, but it showed up for construction, not for a SaaS dashboard.

Put the six names on one grid and the category starts to look like a rounding error with a headline attached. Nscale and Pure DC are landlords for compute. The other four sell tools that sit on top of someone else’s cloud.

H1 2026 CLOUD FUNDING LIST

That split is the whole period. The UK share is not a diversified cloud market with a couple of large rounds at the top. It is two borrowers.

THE EIGHT DEALS IN ORDER

1. January 12, 2026: Cast AI takes a strategic cheque that lifts its valuation above $1 billion, with no amount published.
2. February 3, 2026: enclaive closes a €4.1 million seed for multi-cloud confidential computing.
3. February 12, 2026: Nscale signs a $1.4 billion delayed-draw loan backed by GPUs.
4. March 9, 2026: Nscale closes a $2 billion Series C at a $14.6 billion valuation.
5. April 2026: Blocks raises $6 million to put an agent on the cloud bill.
6. May 11, 2026: Nscale adds $790 million of debt from Nordic and Dutch banks.
7. May 2026: Zerops raises a $2 million seed for its own PaaS.
8. May 28, 2026: Pure Data Centres secures $2.7 billion against Dublin, Amsterdam and a corporate facility.

Add the three disclosed continental software rounds and you still do not reach a single Nscale coupon. Cast AI is the eighth deal and the one blank cell, which is how a unicorn can land on a funding list without moving the euro total.

Nscale’s $4.19 Billion Came in Three Cheques

Nscale is a London AI hyperscaler founded in 2024 by chief executive Josh Payne. It sells GPU compute, networking and a software layer out of halls it owns or colocates, with a pitch built on cheap renewable power in the Nordics. In H1 2026 the company stacked three financings that the sector tally treats as cloud money.

NSCALE’S THREE H1 2026 CHEQUES

• February 12: A $1.4 billion delayed-draw term loan backed by GPUs, for clusters in Norway, Portugal, Iceland and the UK.
• March 9: A $2 billion Series C led by Aker ASA and 8090 Industries, valuing the firm at $14.6 billion.
• May 11: $790 million of debt from ABN AMRO, DNB, Eksfin, Nordea and SEB.

Those three figures are the $4.19 billion. The March round is the one Nscale billed as the largest Series C in European history, with support from Astra Capital Management, Citadel, Dell, Jane Street, Lenovo, Linden Advisors, Nokia, NVIDIA and Point72. Goldman Sachs and J.P. Morgan ran the placement, and the company said the raise is inclusive of a pre-Series C SAFE. That SAFE was $433 million, announced in October 2025, so part of the “H1” equity cheque was already committed the year before.

Sheryl Sandberg, Susan Decker and former UK deputy prime minister Nick Clegg joined the board with the Series C. Aker, the Norwegian industrial group that co-led the round, also rolled an Aker Nscale joint venture into the company, with Aker chief executive Øyvind Eriksen staying on the board as a leading shareholder. The February loan is the cleaner tell. Nscale signed a $1.4 billion GPU-backed loan led by funds managed by PIMCO, Blue Owl and LuminArx, with Goldman Sachs as sole structuring and placement agent. The cash pays for chips against signed customer contracts, plus extra clusters still in the pipeline. It followed a $1.1 billion Series B in September 2025.

This GPU debt financing is a key step in meeting that demand

Payne’s own words put the product in the right bucket. This is a loan against accelerators. The cloud label is how the ranking files it.

Pure DC Borrowed Against Dublin and Amsterdam

Pure Data Centres is the other UK name, and it is even less of a software company. London-headquartered and owned by Oaktree Capital, it buys land, builds halls and leases them to hyperscalers. In late May it announced $2.7 billion of financing: a $2.15 billion facility secured on the Dublin and Amsterdam campuses, and a corporate line lifted to $550 million. The two pieces are the $2.7 billion.

SMBC, ABN AMRO and Allianz were among the lenders, and the $2.15 billion slice was syndicated inside three months. Amsterdam is fully leased, with construction under way. The Dublin campus at Ballycoolin is designed for up to 150 MW of IT load, with 54 MW permitted, and already carries a net-zero microgrid. Gary Wojtaszek, executive chairman and then interim chief executive, said the corporate line was there to move faster on FLAP-D infill sites and larger AI campuses across Europe and the Middle East.

The H1 cheque did not close the story. On October 22, Pure DC and warehouse landlord SEGRO said they would form a joint venture for a 56 MW fully fitted hall at Park Royal in west London, a 30,000 m² three-storey building with gross capital of €1.1 billion. SEGRO puts in the land and about €175 million of equity. Pure DC puts in 70 MVA of secured power. Build is due to start in 2026, with completion aimed at 2029, and a long lease to a global hyperscaler is the plan. Dawn Childs, Pure DC’s chief executive, called it SEGRO’s first fully fitted data-centre development.

That is campus finance with a tenant at the end of it. It is cloud only in the sense that the tenant will sell cloud on top.

The Software Layer Drew Seed-Scale Cheques

Once the two UK landlords are stripped out, Europe’s “most funded cloud companies” are a pre-seed cost agent, a confidential-computing seed, a Prague PaaS, and a Lithuanian unicorn that would not disclose the cheque. They are the firms a finance team actually logs into.

Blocks Puts an Agent on the Cloud Bill

Berlin’s Blocks raised $6 million in April, led by Speedinvest with Caesar Ventures and a cluster of European founders, including names from Flix. Co-founders Oliver Merkel, who also started grocery app Flink, and Andreas Schroeter are selling an AI-powered layer for cloud spend that tunes running systems and pools buying power across customers. The company said it already served more than 50 firms in Europe and would use the money to build product and widen reach. It is a pre-seed that exists because hyperscale bills got away from the people paying them.

enclaive Sells a Vault the Landlord Cannot Open

Berlin’s enclaive, founded in 2022, closed a €4.1 million seed round on February 3, co-led by Join Capital and the Amadeus APEX Technology Fund, with Auriga Cyber Ventures in the round. The 20-person team’s Multi Cloud Platform wraps Kubernetes clusters, virtual machines and AI jobs in hardware enclaves so data stays encrypted while it runs, with no code rewrite. Co-founder and chief executive Andreas Walbrodt put the gap in one line.

Cloud adoption has moved faster than trust. As companies push AI and sensitive workloads into multi-cloud environments, they need security guarantees that go beyond policy and perimeter defenses.

Ion Hauer, a principal at APEX Ventures, tied the same product to a political problem: US cloud statutes that can reach data on foreign servers, and a European wish to keep that data unreadable even if a demand arrives. The raise funds sales, the eMCP product and a first push abroad. It is a seed cheque against a sovereignty argument that the UK GPU build does not answer.

Zerops and Cast AI Work the Other Side of the Rack

Prague’s Zerops raised $2 million in May, led by Gi21 Capital, for a PaaS on its own bare metal. Linux containers, databases and a single path from development to production are the offer, with extra tools so AI coding agents can talk to the infrastructure. The round is for more kit, more product and a larger team, including a push into the United States and Asia. It is a cloud company in the old sense, and it raised what a seed looks like when the category is not a data hall.

Cast AI is the name that breaks the seed pattern without breaking the euro tally. On January 12 the Vilnius-rooted Kubernetes automation firm said a strategic investment from Pacific Alliance Ventures, the US venture arm of South Korea’s Shinsegae Group, a conglomerate it put at over $50 billion, lifted its valuation exceeds $1 billion. The amount stayed unpublished, which is why it can sit on a most-funded list and still be the blank cell. Unicorns Lithuania called it the country’s fifth unicorn, after Vinted, Nord Security, Baltic Classifieds Group and Flo Health, with nearly 80 staff in Lithuania on an average monthly salary of €8,200 and about 300 people across 34 countries.

The same morning Cast AI launched OMNI Compute, a control plane that finds spare capacity, including GPUs, across clouds and regions and attaches it to existing Kubernetes clusters without a code change. Oracle is one of the clouds offering GPUs through that layer. President and co-founder Laurent Gil said the point was to make GPUs fungible so capacity is not trapped in one region. A $108 million Series C in 2025, led by G2 Venture Partners and SoftBank Vision Fund 2, had already paid for offices in Bangalore, London, New York and Tel Aviv. Co-founder and chief executive Yuri Frayman said the Shinsegae cheque was about scaling that automation worldwide. BMW, Cisco, HuggingFace and Swisscom are among the logos on the press note.

So the one continental firm that cleared a billion-dollar valuation did it by helping customers spend less on the same clouds, and by brokering GPU time they do not own. The ranking still files it under cloud. The cheque size never entered the €5.9 billion sum.

Who Wrote the Cheques

Follow the names on the term sheets and the “European cloud” label thins out. Norwegian industry, US credit, a chipmaker, a Los Angeles buyout firm and a Korean retailer did more of the writing than a classic European software fund.

THE CAPITAL BEHIND THE LIST

• Aker ASA: Norwegian industrial group that co-led Nscale’s Series C and folded a Norway joint venture into the company.
• NVIDIA, Dell, Nokia: Strategic names on Nscale’s cap table, sitting beside Citadel, Jane Street and Point72.
• PIMCO, Blue Owl, LuminArx: Credit funds that led the $1.4 billion GPU loan.
• Oaktree Capital: Owner of Pure DC, with SMBC, ABN AMRO and Allianz on the $2.7 billion package.
• Speedinvest and Join Capital: The European VC cheques, both seed-scale, for Blocks and enclaive.
• Shinsegae’s Pacific Alliance Ventures: The unnamed Cast AI cheque that created Lithuania’s fifth unicorn.

That roster is why a UK deeptech boom can be real and still leave the software layer thin. The large money is paying for power, land, chips and halls. The small money is paying for cost control, enclaves and a PaaS. One reply to the March celebration of Nscale’s round put it as a national habit: British scale-ups get built, then sold west. The H1 cap tables already look like that partnership, without waiting for a sale. Nvidia is on the equity line. US credit is on the GPU line. Oaktree is on the campus line.

Huang Told Nscale to Work Around the Clock

By autumn the firm that took the most H1 cloud money was being talked about as a listing, not as a seed. Nscale filed New York papers in September 2026. Chief executive Josh Payne told staff in October that demand was still “insatiable” and that a listing before the end of 2026 remained the plan, at a company target of $30 billion to $35 billion. Some investors have discussed a band of $16 billion to $19 billion. Those are two different prices for two different sides of the same table.

On October 22, Nvidia chief executive Jensen Huang, speaking at a press conference in Berlin, said he had told Nscale to hustle through delays, equipment trouble and power limits at some sites.

Come, you guys, do a good job, work around the clock

Jensen Huang, Chief Executive Officer, Nvidia, Berlin press conference, October 22, 2026

Huang added that the company has strong customers and high demand, and that what it needs is working capital. That is a supplier talking to a landlord, not a verdict on a SaaS multiple. It is also the aftertaste of a funding list that treated GPU loans as cloud equity. The halls still have to come online. The software names on the same list already ship. They just did not raise the money that gets counted.

Europe did fund cloud in the first half of 2026. It funded two UK yards for other people’s models, then wrote seed cheques for the tools that try to make those yards cheaper, safer and easier to use.
