British AI cloud provider Nscale is preparing to list on the NYSE at a $35 billion valuation, aiming to raise $3 billion. The company's IPO filing reveals over $103 billion in contracts, with about 85% concentrated in two customers: Microsoft and Anthropic. Revenue rose to $140.6 million for the six months to June 30, but net losses widened to $1.02 billion.

British AI cloud provider Nscale is preparing to list on the New York Stock Exchange, with an expected valuation of $35 billion and a planned raise of $3 billion. What is truly on the table is not the valuation, but the structure of its $103 billion in contracts—about 85% of which comes from Microsoft and Anthropic—and the clause in the Anthropic agreement that is contingent on financing and allows exit if milestones are not met.
Nscale's listing plan itself is not complicated: the British AI cloud provider is preparing to list on the New York Stock Exchange, and according to the Financial Times and Bloomberg, it expects to list at a $35 billion valuation and plans to raise $3 billion. These two figures have not yet been officially priced and confirmed by the company; they are media-reported figures.
What is complicated is what it has to persuade investors to accept. The IPO filing shows that Nscale's cumulative contract value exceeds $103 billion, and about 85% of that comes from just two customers. Building a company's valuation on such a denominator is equivalent to splitting "contract scale" and "contract quality" into two separate questions and pricing them separately.
Therefore, this IPO is seen as a test of whether investors are willing to bet on an AI cloud vendor dependent on Microsoft and Anthropic. This is an inference, not a statement of fact: it comes from the confirmed fact of contract concentration, not from any public statement by either party.
The identities of the two customers are clear. Nscale has a $43.8 billion compute agreement with Microsoft running through 2033, and a $44.6 billion supply agreement with Anthropic. Together, the two contracts total $88.4 billion, forming the main body of the $103 billion total contract value.
But the two contracts are not the same in the nature of their risk. The key variable in the Microsoft agreement is time—it runs through 2033 and is a long-cycle commitment. The key variable in the Anthropic agreement is conditions: it is contingent on Nscale obtaining financing, and the filing says the milestones it must meet are very strict; if they are not met, the AI lab can exit.
This means that $44.6 billion is already included in total contract value in an accounting sense, but in an execution sense it still hangs on a precondition. The distance between contract value and recognizable revenue is precisely the part of this prospectus that is hardest for valuation models to absorb.
For the six months ended June 30, Nscale's revenue rose from $10.4 million in the year-earlier period to $140.6 million. This growth rate itself is the most intuitive positive signal in the filing.
Another set of figures in the same filing points in the opposite direction: over the same period, net loss widened from $369 million to $1.02 billion. Revenue grew about 13.5 times, while the loss widened about 2.8 times.
Putting these two sets of figures together with the $103 billion in contracts yields a judgment that does not depend on outside information: Nscale's current revenue scale is far smaller than its total contract value, and its losses are still widening. The contracts are about the future; the losses are about the present.
Earlier this month, Nvidia agreed to provide $1 billion in convertible debt as part of a $3.1 billion financing package. This is a confirmed fact, but it is also part of the puzzle that makes up the precondition in the Anthropic agreement.
What needs to be distinguished is this: the $1 billion in convertible debt belongs to the $3.1 billion financing package, and that package has not yet fully landed. The Anthropic agreement requires Nscale to obtain financing, the milestone requirements are strict, and Anthropic can exit if they are not met. Therefore, the progress of the financing package directly bears on whether the $44.6 billion contract can stand as originally written.
There are two layers of uncertainty here: whether the rest of the $3.1 billion financing package can be secured is still uncertain; and even if the financing comes through, whether the milestones required by the Anthropic agreement can be met is also still uncertain. Neither is within Nscale's unilateral control.
Nscale was spun out two years ago from the Australian cryptocurrency mining company Arkon Energy. This origin explains why it was able to accumulate data center assets in a short time, and also explains why it lacks a long-cycle operating record.
The company currently operates data centers in Norway, Portugal, Texas, and West Virginia. Board members include former Meta executives Sheryl Sandberg and Nick Clegg, as well as former OpenAI executive Fidji Simo.
The constraint of a short operating history, combined with the constraint of customer concentration, forms two things investors need to digest at the same time: the company neither has a long enough performance record to prove it can execute through 2033, nor a sufficiently diversified customer structure to hedge the risk of execution failure.
Nscale was previously valued at $14.6 billion in a $2 billion Series C round led by Aker ASA and 8090 Industries. If the media-reported $35 billion listing valuation is used, the valuation has moved up another step after Series C.
Whether this jump holds depends on how the market discounts "total contract value." A $103 billion contract, 85% concentrated in two customers, $44.6 billion of which carries a financing precondition, and a half-year net loss of $1.02 billion—these figures together form the case for a discount, while revenue rising from $10.4 million to $140.6 million forms the case for a premium.
It must be made clear that whether Nscale can complete an IPO at a $35 billion valuation and a $3 billion size is still uncertain. The media-reported valuation and fundraising size have not yet been officially priced and confirmed by the company.
Stringing the above facts together, Nscale's IPO is in effect asking the market a specific question: when an AI cloud vendor's revenue structure is highly dependent on two customers, one of which also retains the right to exit if financing conditions are not met, how much are investors willing to pay for its total contract value?
There is no precedent for this question, because Nscale's combination is unusual: a two-and-a-half-year operating history, $103 billion in contracts, 85% customer concentration, a $1.02 billion half-year net loss, and a $3.1 billion financing package that has not yet fully landed.
If Anthropic exercises its exit right, how Nscale's contract revenue structure would be affected is still uncertain; investors' acceptance of AI cloud vendors highly dependent on a few large customers is still uncertain; and whether the continuously widening net loss will hinder the listing process is also still uncertain. These three uncertainties will not disappear once the listing is completed; they will merely shift from the prospectus into the everyday pricing of the secondary market.
All facts in this article come from a single source (The AI Insider, September 23, 2026) reporting on Nscale's IPO filing. Of these, the $35 billion valuation and $3 billion fundraising size are explicitly labeled by that report as coming from the Financial Times and Bloomberg, and have not yet been officially priced and confirmed by Nscale; they should be treated as media-reported figures rather than company confirmation. Contract amounts, customer concentration, financial data, Nvidia financing, the Series C valuation, the spin-off background, data center locations, and board composition are all cited from the IPO filing or from direct statements in that report. The judgment that "this IPO is a test of investor appetite" is an inference rather than a fact, and has been labeled as such in the body text. The impact of Anthropic's exit right, the securing of the rest of the financing package, and whether the listing can be completed at the reported size are all uncertainties explicitly listed by the source, and this article makes no predictions beyond the source.
Nscale's IPO is not an ordinary AI infrastructure listing, but a public test of whether "total contract value can be equated with enterprise value." The $103 billion in contracts and the 85% customer concentration are two sides of the same coin, and the clause in the Anthropic agreement that is contingent on financing and allows exit if milestones are not met turns part of that contract into a conditional asset. What investors ultimately price is not how much Nscale has signed, but the extent to which those signings will be honored.
