Nscale’s first draft registration statement, submitted to the SEC on 17 February 2026 and now public on EDGAR, names ByteDance as the company’s largest customer for 2025.
The four filings that followed, amended drafts of 12 May, 26 June and 12 August 2026 and the Form S-1 of 18 September 2026, do not name ByteDance. They give the largest customer’s 2025 share instead: 73% of revenue.
Business Pill · CONCENTRATION
A one-minute explainer of concentration: how much of a total comes from its largest few parts. It teaches the general idea only and says nothing about any company in this story.
The key insight: As we read it, the filings tell two stories at once: the name of Nscale’s largest 2025 customer appears in one draft and then goes, while the largest-customer share the filings report falls from 73% for 2025 to 52% for the first half of 2026, without saying whether it is the same customer.
The 17 February draft, filed under the name DSNS Holdings Ltd with the same SEC company number as Nscale (CIK 0002110365), says: “For the year ended December 31, 2025, our largest customer was ByteDance, which accounted for % of our revenue.” The percentage is blank in that draft.
The same risk factor names ByteDance alongside Microsoft. It says “Any negative changes in demand from Microsoft or ByteDance, in Microsoft’s or ByteDance’s ability or willingness to perform under its contracts with us, in laws or regulations applicable to Microsoft or ByteDance or the regions in which they operate” would hurt the business.
That draft puts the Microsoft agreements of 12 September 2025 at payments “of up to approximately $35.0 billion through December 2031,” not counting optional extensions.
Nscale’s largest customer as a share of revenue, as the S-1 of 18 September 2026 gives it: 93% in 2024, 73% in 2025 and 52% in the first half of 2026. The 17 February draft named the 2025 largest customer as ByteDance; the later filings do not name it.
What the Later Filings Say
From the 12 May amended draft onward, the sentence no longer names a customer. The May draft says: “For the year ended December 31, 2025, our largest customer accounted for 73% of our revenue.”
Both versions describe the same thing, Nscale’s largest customer for the year ended 31 December 2025. The February draft gives the name and leaves the share blank; the later filings give the share and leave out the name.
The S-1 of 18 September adds a newer figure: “For the six months ended June 30, 2026, our largest customer accounted for 52% of our revenue.” Its notes put the largest customer’s share for 2024 at 93%.
In the S-1 the risk factor reads “Any negative changes in demand from Microsoft, Anthropic, or our other key customers”.
The Microsoft figure changed separately. The May and June drafts keep the February wording, up to approximately $35.0 billion through December 2031. The 12 August draft and the S-1 say statements of work signed between September 2025 and April 2026 provide for payments “of up to approximately $43.8 billion through December 2033.”
Mentions of “ByteDance” in the main document of each Nscale filing on EDGAR, counted by FourWeekMBA: five in the 17 February draft, none in the drafts of 12 May, 26 June and 12 August or in the S-1 of 18 September.
How We Checked
We searched EDGAR’s full-text index for “ByteDance” within Nscale’s company number; it returns one document, the 17 February draft.
We also downloaded the main document of each of the five filings and counted the name: five mentions in the February draft and none in the May, June and August drafts or the S-1.
None of the five documents uses the name Spring, the Singapore entity the Financial Times named on 23 September. We covered that report the same day, when no company had confirmed the figures.
The Structural Read
The February draft says Nscale’s largest customer for 2025 was ByteDance and leaves the percentage blank. Every later filing fills in the percentage, 73%, and drops the name.
The risk factor changes with it. In February it names “Microsoft or ByteDance”; in the S-1 it names “Microsoft, Anthropic, or our other key customers”.
The S-1 gives a third data point on concentration: the largest customer was 93% of revenue in 2024, 73% in 2025 and 52% in the first half of 2026.

Three Implications
INVESTORS READING THE S-1 The S-1 gives the largest customer’s share without its name; the 17 February draft on the same EDGAR page is where the name appears.
NEOCLOUD BUYERS AND LENDERS Per the S-1, Nscale’s largest customer in the first half of 2026 made up 52% of its revenue, and the Microsoftstatements of work run to December 2033.
ANYONE TRACKING THE RISK FACTORS The S-1’s key-customer risk factor now names Microsoft and Anthropic, where the February draft named Microsoft and ByteDance.
The framework’s starting point: “The May 2026 Map of AI argued that the seven-layer AI stack is now governed from the bottom — energy, silicon, compute capacity.”
As we read it, a neocloud’s customer list is the bottom layer’s demand made visible: who rents the capacity, and how much of the revenue rests on one name. The filings show the customers named in the risk factor changing from Microsoft and ByteDance to Microsoft and Anthropic; they do not say why the ByteDance name was dropped.
What Is Not Established
The filings do not say why the name was dropped, and we did not ask Nscale or ByteDance. We did not read the Telegraph article that prompted this check, or any SEC comment letters; none appears in Nscale’s EDGAR filing list as of 10 October 2026.
The S-1 is a registration statement, not a final prospectus; no 424B prospectus appears in Nscale’s EDGAR filing list as of 10 October 2026. No wrongdoing is alleged here by us or, in what we read, by anyone else.

Nscale’s own filings show the change: the 17 February draft names ByteDance as its largest 2025 customer, and every filing after it gives that customer’s share, 73%, without the name. The S-1 adds a newer figure: the largest customer’s share was 52% in the first half of 2026.
A note on sourcing. We read the main document of each of Nscale’s five SEC filings on EDGAR on 10 October 2026 and searched EDGAR’s full-text index for the name. Figures and quotations are the filings’; the mention counts are ours. We did not read the Telegraph article that prompted the check, and we did not contact Nscale or ByteDance. Nothing here is a forecast, and nothing here is financial or investment advice.
