Nscale files for IPO with $103 billion in contracts – 85 percent from Microsoft and Anthropic
Anthropic's stock market debut is, according to several reports, in motion: the company reportedly valued at around $2 trillion, with up to $100 billion in offering proceeds, and reportedly pushed from October toward November. But Anthropic is only the most visible piece of a tightly interwoven financing chain – where retail investors buy risky pre-IPO exposure, and where Britain's Nscale has filed to go public with contracts worth over $103 billion that in practice rest on two customers: Microsoft and Anthropic. This article maps who is listing, who depends on whom, which numbers are actually solid – and which questions the market has not yet answered.
The news: a debut in motion
According to the Daily Mail, citing people familiar with the plans and the Wall Street Journal, Anthropic's stock market debut is being pushed toward November, from a previously expected October listing. The same report states that the company is reportedly discussing a valuation of around $2 trillion and a possible capital raise of up to $100 billion – which would make it one of the largest public offerings ever.
The figures and timing, however, are not confirmed. There are as yet no primary documents: the valuation, the proceeds and the November date all trace back to "reports" via the Daily Mail with reference to the Wall Street Journal and anonymous sources, and the reporting itself suggests the timing is not set in stone.
There is also an open contradiction in the source material. Bloomberg reporting carried via WealthManagement.com said on September 21 that Anthropic was "expected to sell shares in the coming weeks". The next day, the Daily Mail wrote that the debut could slip toward November. Both may reflect planning in flux – but neither can yet disconfirm the other. Readers should therefore treat both the timing and the size as unstable, not as fact.
What is well documented, by contrast, is the context: OpenAI has, according to the same Bloomberg report, discussed its own listing next year, and Seeking Alpha calculates that the combined valuations of OpenAI, Anthropic and SpaceX exceed the first-day value of all U.S. tech IPOs from 1980 to 2025. The methodology behind the comparison is not visible, but the order of magnitude points to the same story: the private valuations of the AI economy now exceed the public market history against which they are to be measured.
Retail: investors buying exposure the company itself warns against
While Anthropic remains privately held, retail investors are flowing into funds and vehicles promising pre-IPO access to Anthropic and OpenAI, according to Bloomberg's reporting (reporter Zijia Song, carried via WealthManagement.com). Some commit large shares of their wealth.
The structure carries its own risks. Typical pre-IPO products are built as special purpose vehicles (SPVs) or feeder funds: the investor pays fees to the middleman, the shares are locked up (lockup) for a period after listing, and there is no liquidity between subscription and any eventual sale. If the listing slips – as the reporting now suggests – this entire marketplace slips in time as well, without the investor being able to step off.
The company itself has sharpened the picture. According to the Bloomberg reporting, Anthropic CEO Dario Amodei spoke out against unauthorized secondary sales and SPVs, warning investors that the company may choose not to recognize shares transferred without its consent. After the warning, demand nonetheless rose, and a range of investment products continue to promise exposure to the company.
It is worth underscoring what this means in practice: an investor going through an unauthorized vehicle risks, in the worst case, holding a contract against a company that does not acknowledge that the shares have been transferred. That is a legal and liquidity risk that sits ahead of all the ordinary listing risks – price, lockups, market sentiment – and it exists now, before any share has been listed.
The chain: Nscale and the concentration in the contracts
The most clearly documented piece of the interwoven economy is Nscale, a British "neocloud" company spun out of the Australian crypto-mining firm Arkon Energy two years ago. According to TechCrunch, which has seen the company's IPO filing, Nscale has contracts worth over $103 billion.
The catch is the distribution. Roughly 85 percent of the contracts come from two deals: a supply agreement worth $43.8 billion with Microsoft, running through 2033, and an agreement worth $44.6 billion with Anthropic. The filing describes the terms around financing and milestones in the Anthropic agreement as "stringent" – that is, conditional on both parties actually managing to finance and deliver what has been promised.
The numbers underneath are just as revealing. For the six months through June 30, Nscale reported revenue of $140.6 million, up from $10.4 million the year before – but net losses jumped to $1.02 billion, from $369 million. The company is thus building capacity against contracts not yet fulfilled, with losses running at seven times its revenue.
This is the mechanism that binds the AI economy together: a model developer (Anthropic) signs compute agreements with an infrastructure provider (Nscale), which builds data centers against future revenue and lists on the stock market to finance the build. At the same time, Anthropic's own ability to pay for the compute is tied to revenue from customers and – via the listing – from public investors. The value in the chain loops back to the same few companies. A delay at Anthropic therefore hits not only Anthropic: it hits the valuation logic of an entire tier of infrastructure companies now to be assessed by public markets.
The cooling: Wall Street doubts the data centers
Even as Nscale prepares to test the market, other infrastructure listings are moving backwards. New York Times (Maureen Farrell, September 21) reports that investors are expressing growing skepticism about the growth expectations for data centers and the risks of the buildout, and that industry executives and advisers are therefore recalibrating plans to raise tens of billions of dollars in public markets. Concretely: SB Energy has sought a valuation of $50 billion or more, and Holtec has postponed its stock market listing indefinitely.
This puts Anthropic's potential giant listing in a double light. On the one hand, a successful $2 trillion debut could serve as a vote of confidence for the entire sector – a signal that the market is still paying top dollar for AI exposure. On the other hand, a disappointing offering, or a further delay, points in the same direction: if even Anthropic cannot sell shares at reported prices, it becomes harder for all the dependent infrastructure listings – including Nscale – to sell their share of the story. The valuation multiplier works in both directions.
The safety dimension – handled with care
The Daily Mail links the delay to warnings from whistleblowers that AI is developing too quickly and could become impossible to control, writing that former Anthropic researcher Jacob Coxon has resigned and warned that companies like Anthropic and OpenAI are moving too fast toward ever more powerful systems – comments that, according to the newspaper, received over 100 million views. These claims rest exclusively on the Daily Mail's account; neither Coxon's own statement nor any whistleblower letters are available in the source material, and they should therefore not be treated as independently confirmed. Nor is it documented that the whistleblower warnings actually caused a delay.
There is, however, one confirmed detail in the same source: Anthropic itself has stated that this year it blocked several attempts to use its systems for research that could potentially have been used to develop biological weapons. This is a company claim, not an independent assessment, but it points to a real tension the market must grapple with: the company potentially to be valued at $2 trillion is also the company whose products have, by the company's own account, had to be blocked for misuse, and whose own former employees have publicly warned about the pace of the race. Reading this purely ironically – that the safety debate could delay a listing meant to finance that same pace – is analysis, not documented fact. But it is a question investors genuinely must ask: how much safety risk is being priced in, and how much priced out?
Open questions – and honest uncertainty
Nothing in this material is a primary source in the strict sense. There is no public Anthropic filing yet, no confirmed prospectus valuation, no confirmed date. Concretely, that means:
- The roughly $2 trillion valuation and the up to $100 billion in proceeds are reported figures via the Daily Mail/WSJ, not documented. They could change before any filing.
- The timing is directly contradictory: Bloomberg (September 21) said "coming weeks"; the Daily Mail (September 22) said November. Both may reflect planning in motion. Neither can be clarified from here.
- The whistleblower and Coxon claims rest exclusively on the Daily Mail's characterization.
- Seeking Alpha's comparison between OpenAI/Anthropic/SpaceX and 45 years of tech IPOs is a compressed figure with no visible methodology; it is illustrative, not an audited calculation.
- The Nscale figures are the most solid in the material, because TechCrunch cites an actual filing – but the filing's own assumptions ("stringent" conditions) show that even the $103 billion are conditional future revenues, not money in the bank.
What remains, however the timing question resolves, is this: the stock market route for the AI economy is now underway, and it is structured as a chain, not as independent listings. Retail investors are buying exposure the companies themselves warn against, infrastructure companies are listing with customer concentration among the same two or three buyers, and Wall Street is beginning to price in the fact that the entire construction rests on a few companies continuing to grow at the pace they themselves have promised. Anthropic's debut – whether it happens in October, November or later – will be the point at which the market for the first time has to set a public, unmediated price on precisely that claim.
