A multibillion-pound government initiative to "mainline AI into the veins" of the British economy is riddled with "phantom investments" and questionable accounting practices that inflate claimed economic impact while delivering little tangible infrastructure, a Guardian investigation published March 9 has found.
The investigation examined massive AI investments announced by successive Conservative and Labour governments since 2024, comparing promised deals with actual deliverables. The findings center on two Nvidia-backed companies—Nscale and CoreWeave—that are central to the UK's AI infrastructure plans but whose claimed investments do not represent genuine capital flowing into the British economy.
Promised Supercomputer Site Still Used as Scaffolding Yard
The Guardian visited a site in Loughton, Essex that is supposed to host "one of the most powerful AI computing centres ever built" by Nscale. The location remains in use as a scaffolding and construction equipment yard with no evidence of data center construction underway, despite government announcements describing the project as a signed contract representing part of Nscale's $2.5 billion UK investment commitment.
When the Guardian asked the UK government about the contract it claimed had been signed to build the supercomputer, officials did not answer directly. Instead, the government clarified that the entire $2.5 billion Nscale investment involved no formal contract but rather an "intention to commit capital"—a significant distinction that calls into question how firmly these announced investments are actually committed.
Government Admits No Audit Mechanism for Claimed Investments
The Guardian questioned the government about key investments worth billions of pounds from companies including Nscale and CoreWeave. Officials acknowledged that investment figures came from the companies themselves and that the government has no mechanism in place to audit these claims. The government could not specify what these investments actually involve—whether equipment purchases, capital expenditures, or other forms of spending.
This admission reveals a fundamental accountability gap: the UK government has been announcing multibillion-pound AI investment figures in press releases and policy statements without independent verification of whether those investments represent real capital deployment, inflated equipment valuations, or aspirational commitments contingent on future conditions.
Investments May Primarily Mean Nvidia Chip Purchases for Rental
Both Nscale and CoreWeave have indicated that a large portion of their massive UK investments will take the form of Nvidia GPU chips that the companies will purchase and install inside UK data centers, then rent out to users including U.S. tech companies. This structure raises questions about what "UK investment" actually means when capital flows primarily from company to chipmaker, with the resulting infrastructure owned by private companies and rented to customers rather than representing lasting British economic assets.
For example, Nscale's $2.5 billion "investment" in the UK may largely mean that Nscale plans to buy a massive number of chips from Nvidia, install them in data centers on UK soil, and rent compute capacity to customers. While this creates some local jobs and tax revenue, it differs substantially from traditional infrastructure investment that builds lasting national capabilities.
The investigation notes that new data centers touted in government announcements are not actually new—in several cases, they represent existing facilities being rented or repurposed rather than greenfield construction projects creating new infrastructure capacity.
Nscale Shareholders Positioned for 350,000% Returns
The Guardian's analysis revealed that Nscale allocated shares at a price of 1 pence in October 2025. Following the company's March 9 announcement of a $2 billion funding round at a $14.6 billion valuation, those shares are now worth many times their October price. An analyst who examined the figures for the Guardian calculated the increase as "kind of a 350,000% return on investment."
Early shareholders could make substantial fortunes when Nscale completes a public offering—exactly how much depends on AI market sentiment at the time of the IPO. This creates powerful financial incentives for inflating investment claims and valuations during private funding rounds, with verification of actual infrastructure deployment often years away.
Pattern Echoes Broader AI Investment Hype Concerns
The Guardian's investigation arrives as questions intensify globally about whether announced AI infrastructure investments reflect genuine capital deployment or aspirational commitments amplified by government officials eager to claim economic development wins. The UK government under Prime Minister Keir Starmer has made AI infrastructure central to its economic growth agenda, creating political pressure to announce large investment figures regardless of verification mechanisms.
The findings parallel concerns raised about AI investment announcements in other jurisdictions where governments tout multibillion-dollar commitments from tech companies without clear accountability for whether promised data centers, jobs, and economic activity actually materialize on stated timelines.
For the UK specifically, the investigation raises fundamental questions about the government's AI strategy: whether claimed investments represent transformative infrastructure buildout positioning Britain as an AI superpower, or whether they primarily represent inflated valuations and equipment purchases benefiting chipmakers and private infrastructure companies while delivering limited lasting economic benefit to the UK economy.
The government did not provide substantive responses to the Guardian's specific findings about missing infrastructure, unaudited investment claims, or the gap between announced commitments and verifiable capital deployment.
