Nebius has entered the UK with a deployment of Nvidia Blackwell Ultra GPUs.

The deployment will include thousands of the Nvidia Blackwell Ultra GPUs – the B300s – and is expected to be operational in Q4 of this year.

Arkady Volozh, founder and CEO of Nebius, said: “We’re pleased to be providing compute infrastructure that will support future innovation by British businesses, researchers, and the public sector. The UK is where AI is being built, tested, and deployed at scale across industries from fintech to life sciences. Being here puts us closer to the startups, researchers, and enterprise leaders shaping what’s next.”  

Dave Salvator, Nvidia’s director of accelerated computing products, added: “Local infrastructure gives enterprises and startups in every nation a foundation for building their own AI-enabled future. Nebius’s UK-based Nvidia Blackwell Ultra infrastructure will support British innovators in developing and deploying advanced reasoning, agentic, and physical AI applications.”  

It has not been specified where the cluster will be housed, as Nebius does not yet list a data center in the UK. Nebius currently owns a data center in Finland, around 60km from Helsinki, where they house thousands of GPUs and a supercomputer.

In the US, the company is working with DataOne to develop a 300MW data center in New Jersey, the first phase of which is expected to go live in the summer of 2025. Nebius is also set to lease space at an upcoming data center in Kansas City, Missouri.

The company has further colocation presence in Iceland and France, the latter in an Equinix facility in Paris.

In May 2025, Nebius revealed it would build and operate a $140 million national supercomputer in Israel, part-funded by the Israeli government’s Innovation Authority.

DCD has contacted Nebius for more information about its UK footprint.

Nebius recently launched a team in the UK, providing specialist offerings to the healthcare, life sciences, biotech, financial services, and generative AI sectors, as well as research institutes, including the London Institute of Mathematical Sciences.

The AI cloud provider raised $1 billion in convertible debt financing this month, to be used for expanding its data center footprint and to acquire further AI hardware.

Nebius was formed last year after Russian tech firm Yandex’s European operations were spun off into a separate entity. Based in Amsterdam, Nebius took control of Yandex’s Finnish data center, its Nebius AI unit, as well as data firm Toloka AI, edtech provider TripleTen, and autonomous driving firm Avride.

The company is aiming to achieve a baseline of 100MW of capacity in 2025, but according to COO Roman Chernin, the ambition is actually to grow “much larger and much faster” with the company looking to build a data center pipeline to provide “scalability to more than 1GW of power.”
