Nscale Faces Investor Pushback on $30 Billion IPO Valuation After Microsoft Cancels UK Data Center

When Australian artificial intelligence infrastructure firm Firmus scrapped its initial public offering earlier this month, the collapse was attributed to a general cooling of the neocloud market. Nscale's current listing struggle shares that chilled environment, but its valuation crisis stems from a highly specific physical bottleneck: a local power grid in Essex that cannot supply electricity until the next decade.[2][4]

The London-based data center developer is facing severe investor pushback against its $30 billion IPO valuation target. A cohort of prospective buyers is instead arguing for a valuation in the $16 billion to $19 billion range, citing operational delays and the loss of a major anchor tenant.[1][2][3]

The valuation standoff follows Microsoft's decision to cancel its agreement for Nscale's planned data center in Loughton, Essex. The withdrawal occurred after UK Power Networks, the local grid operator, informed Nscale that sufficient electricity capacity might not be available until the early-to-mid 2030s.[1][5]

That timeline falls years behind the project's original schedule. The Loughton facility was designed to house 23,040 Nvidia chips and deliver 50 megawatts of computing capacity to Microsoft Azure by the first quarter of 2027, serving as a flagship deployment for the UK market.[5]

Theoretical contracts versus physical power

The cancellation exposes the gap between Nscale's marketed pipeline and its actual operating footprint. While the company's September 18 registration statement boasts $103.4 billion in total contracted revenue, only $2.6 billion of that comes from active, running contracts.[1][2]

The remaining $100.8 billion represents capacity that has yet to be built or powered. In the first half of 2026, Nscale reported $140.6 million in actual revenue against a net loss of $1.02 billion, highlighting the capital-intensive nature of its infrastructure buildout.[2]

The loss of the Loughton site is particularly damaging due to Nscale's concentrated customer base. Microsoft and Anthropic together account for roughly 85 percent of the company's $103 billion contract pipeline, magnifying the financial impact of any single canceled deployment.[1]

Microsoft has framed the withdrawal as a localized infrastructure failure rather than a broader retreat. "This decision relates to a single site," a Microsoft spokesperson said, adding that the technology giant remains committed to its wider partnership with Nscale.[5]

Nscale maintains that the Essex grid constraints are isolated. "Our relationship with Microsoft remains strong and long-term, and this unfortunate London-wide grid issue has no impact on our other contracts," an Nscale spokesperson said, noting the company is exploring alternative power sources for the Loughton site.[1][5]

The convertible note ceiling

The $30 billion valuation target is not an arbitrary figure for the infrastructure developer. In September 2026, Nscale raised $3.36 billion in pre-IPO convertible notes in a round led by Third Point, which included a $1 billion commitment from Nvidia.[1][4]

Those convertible notes were structured to convert into shares at a discount, with the conversion price strictly capped at a $30 billion valuation. That cap now effectively serves as the ceiling that the IPO bookrunners are negotiating against in a much colder market.[1][4]

If Nscale is forced to list closer to the $16 billion range suggested by investors, it would represent a massive haircut for its late-stage backers. It would also sit only marginally above the $14.6 billion valuation the company secured during its private funding round earlier this year.[1][3]

The Loughton grid failure is not the only operational hurdle weighing on Nscale's valuation. The company's flagship data center in Glomfjord, Norway, is reportedly running six months behind schedule due to construction delays and local regulatory hurdles.[1][2]

The Norwegian facility is currently operating at just 6.4 megawatts of capacity, according to recent reports. That output falls significantly short of the site's 30-megawatt target, further eroding investor confidence in Nscale's ability to bring its massive contracted pipeline online in a timely manner.[1]

A broader neocloud selloff

Nscale is attempting to price its offering into a rapidly deteriorating market for independent AI infrastructure providers. CoreWeave, the closest listed comparable in the neocloud sector, lost 25 percent of its market value last week amid rising concerns over its debt load.[2][4]

The selloff has extended across the broader artificial intelligence hardware sector. Shares in Nebius Group have declined 32 percent over the past two weeks, as higher borrowing costs and delayed deployments force investors to reprice the infrastructure boom.[2][4]

Despite the mandatory 15-day regulatory waiting period having expired, formal marketing for Nscale's New York Stock Exchange listing remains on hold. The company is currently working through detailed feedback from the U.S. Securities and Exchange Commission on its preliminary prospectus before launching its roadshow.[2]

The valuation standoff ultimately tests whether public markets will continue to value AI infrastructure firms based on their theoretical order books. A signed contract for tens of thousands of advanced GPUs generates no actual revenue if the facility housing them cannot connect to the electricity grid.[1][2][5]

Nscale's origins in the cryptocurrency sector highlight the aggressive pivot many firms have made toward artificial intelligence. The company grew out of Arkon Energy, a bitcoin mining developer, applying its experience in securing land and power rights to the far more lucrative AI compute market.[5]

Yet the sustained power requirements for training frontier AI models vastly exceed those of traditional cryptocurrency mining operations. As the Loughton cancellation clearly demonstrates, securing a physical site and purchasing the necessary silicon is no longer enough to guarantee a functional, revenue-generating data center.[5]
