The billionaire tech exile behind one of Russia’s biggest companies has pledged to invest almost £2bn in Britain’s AI data centre building spree.
Arkady Volozh, who co-founded Yandex and is worth an estimated $7bn, said he planned to more than triple the company’s UK headcount and spend almost £1.7bn on three new data centres around the country.
Mr Volozh will make the investment through his company, the £50bn US-listed AI giant Nebius, which was carved off from Yandex in 2024 in the wake of Russia’s invasion of Ukraine.
He said: “The UK is one of the few places where AI is being built, deployed, and adopted at the same time – by startups, by enterprises, and by the public sector. The work is happening here and the demand is here. And we are also here for the long run.”
Nebius’s announcement comes before London Tech Week, with the Prime Minister set to give an opening address to industry leaders at the event on Monday.
Labour has been seeking to woo investment from technology giants to fund Sir Keir Starmer’s ambitions to make the UK an AI “superpower”.
As part of its plans for a 20-fold increase in public computing capacity, the Government has announced a new supercomputer and so-called AI growth zones which will house data centres. These data centres are needed to help develop new AI apps or to power existing tools such as OpenAI’s ChatGPT or Anthropic’s Claude.
Nebius’s new sites will offer around 65MW of data centre power by 2027 aimed at British start-ups such as Revolut, which uses the company’s AI computing power to run its fraud detection systems.
It will also target new pharmaceutical start-ups developing drugs using the latest machine-learning technology.
The UK facilities will be based on leased infrastructure and are already hooked up to the power grid, with Nebius supplying powerful AI processors to fill the racks in the centres.
Kanishka Narayan, the AI minister, said: “Nebius’s investment brings significant AI compute into the UK, giving companies what they need to train, test and run advanced systems here at home – helping drive productivity by rolling AI out widely across the economy.”
Nebius was formed after Russia’s invasion of Ukraine, when Yandex was forced into a complex restructuring to carve off its Russian division as it grappled with sanctions and pressure from the Kremlin.
Mr Volozh formally renounced his Russian citizenship earlier this year and has lived in Israel with his family since 2014.
Now based in the Netherlands and listed in the US, Nebius has emerged as one of Europe’s fastest-growing technology companies.
Four leading AI models discuss this article
"Nebius is strategically capturing the 'sovereign AI' premium by providing localized, high-density compute infrastructure that major US hyperscalers are currently underserving in the UK market."
Nebius (NBIS) is positioning itself as the 'sovereign' alternative to US hyperscalers like AWS or Azure, specifically targeting the European regulatory environment. A £1.7bn investment for 65MW of capacity is a significant capital expenditure, but the real value lies in the vertical integration of their AI infrastructure stack. By targeting high-compute sectors like fintech (Revolut) and pharma, they are bypassing the general-purpose cloud wars to focus on high-margin AI training workloads. However, the UK's power grid remains a massive bottleneck; while the article claims these sites are 'hooked up,' the actual latency and reliability of power delivery for high-density GPU clusters often face regulatory and infrastructure delays that could severely impair their 2027 deployment timeline.
Nebius is essentially a 'repackaged' entity with significant legacy operational risks; if they fail to secure consistent, low-cost power at scale, they will be crushed by the sheer economies of scale held by Microsoft and Google.
"This is capital commitment, not revenue—the real test is whether 65MW fills with paying customers by 2027 and whether UK grid/planning doesn't derail execution."
Nebius's £1.7bn UK commitment is real capital into genuine infrastructure scarcity—65MW by 2027 addresses a genuine bottleneck for AI workloads. The timing (pre-election positioning) and Volozh's credibility (built Yandex, $7bn net worth, already exited Russia) suggest serious intent, not PR. However, the article conflates three separate wins: compute supply (good), government backing (political theater), and actual customer demand. Revolut and pharma startups are named but unconfirmed as committed tenants. The 'leased infrastructure' model also means Nebius bears execution risk on power grid integration and cooling—not trivial at 65MW scale in the UK.
Nebius is a 2024 spinoff with no proven track record operating independent data centers at scale; the £2bn pledge could evaporate if UK power costs spike, planning delays hit (common for data centers), or customer demand doesn't materialize beyond press releases.
"Nebius's leased, grid-ready UK sites de-risk near-term AI compute supply more than new-build announcements but still face power-allocation bottlenecks."
Nebius's £1.7bn commitment to 65MW of leased UK AI capacity by 2027 supplies immediate compute for Revolut-style fraud models and pharma ML workloads, aligning with the government's 20x public compute target. The sites are already grid-connected, shortening deployment versus greenfield builds. Yet the UK faces acute power constraints and planning delays; leased infrastructure limits ownership upside and exposes Nebius to landlord or grid curtailment risks. Volozh's Yandex origins add a thin geopolitical overhang despite citizenship renunciation. The move is bullish for near-term AI infrastructure availability but hinges on execution speed rather than capital alone.
UK grid operators have already warned of connection queues stretching into the 2030s; if Nebius cannot secure firm power beyond the initial sites, the pledged capacity may never materialise and the investment could stall like other announced European data-centre projects.
"The core risk is that this looks like branding and political optics rather than a material, cash-generating expansion, contingent on utilization and energy/capital cost realism."
Nebius’s UK push could be a signaling play to ride Britain’s AI infrastructure agenda. The £1.7bn for three data centres and 65MW by 2027 is material, but still modest vs hyperscale benchmarks, suggesting a niche or pilot-scale footprint. The credibility hinges on secured power contracts and chip/systems supply—Nebius says it will supply processors, but chip vendors and energy costs will drive utilization. The political optics are favorable ahead of London Tech Week, yet cross-border risk lingers: a founder with Russian roots and a company carved out from Yandex may invite regulatory and reputational scrutiny, and UK subsidies/permits are not guaranteed. Energy prices and grid constraints could cap upside.
The strongest counter is that 65MW by 2027 may not meaningfully move UK AI capacity given global scale, and the project relies on uncertain utilization, chip supply, and favorable energy costs. If demand softens or subsidies falter, the return profile could disappoint.
"Nebius’s reliance on US-controlled GPU supply chains renders their 'sovereign' value proposition illusory and strategically fragile."
Claude and Grok are glossing over the most critical friction: the 'sovereign' narrative is a double-edged sword. While Nebius courts UK regulators, their reliance on the Nvidia supply chain—which is effectively controlled by US export policy—creates a massive strategic vulnerability. If tensions escalate or US-UK tech alignment shifts, Nebius’s entire business model fails regardless of grid capacity. They aren't building a sovereign cloud; they are building a high-risk, third-party dependent utility with zero moat against hyperscaler pricing.
"Chip supply constraints are symmetric across all players; Nebius's real bottleneck is UK power grid execution risk, not strategic vulnerability to US policy."
Gemini's Nvidia dependency critique is valid but overstates the moat risk. Hyperscalers face identical chip constraints—this isn't unique to Nebius. The real vulnerability is execution: 65MW by 2027 requires secured power contracts NOW, not 2026. Nobody has confirmed whether Nebius has firm grid commitments beyond 'hooked up' language. That's the actual sovereign risk—not geopolitics, but whether UK power infrastructure can deliver on time.
"Leased sites shift AI-specific upgrade risks to landlords who lack incentives to prioritize them over other grid demands."
Claude flags power contract timing well, yet the leased model means landlords control upgrades for high-density cooling and redundancy needed for 65MW AI clusters. UK grid operators prioritize residential and renewables over private data centers, so even 'hooked up' sites may face curtailment. This operational dependency could delay revenues beyond 2027 regardless of Nvidia access or Volozh's track record.
"Firm capacity and reliability guarantees for 65MW are the real gatekeeper; without firm interconnection capacity, Nebius's utilization and IRR collapse."
Claude's emphasis on "secure power contracts NOW" is proper, but it misses a bigger operational risk: the enforceable capacity and reliability Nebius must offer tenants. Even with 'hooked up' sites, UK interconnection offers can be conditional, with curtailment risk and upgrade costs that Nebius or landlords bear. If 65MW isn’t available as firm capacity, utilization and IRR collapse, regardless of Nvidia access or Volozh pedigree.
Despite the significant £1.7bn investment for 65MW of AI capacity in the UK, Nebius faces substantial risks, including power grid reliability, Nvidia supply chain dependency, and potential regulatory scrutiny. The 'sovereign' narrative may not translate into a competitive advantage against hyperscalers.
