As of September 26, 2026, Nscale has a public Form S-1 registration statement on file with the SEC for a proposed U.S. initial public offering, filed September 18, 2026; no listing date, exchange, or price range has been announced. The Nvidia-backed, UK-based AI cloud and data-center operator disclosed in that filing that revenue rose 1,252% in the first half of 2026, to $140.6 million from $10.4 million, according to Reuters' report on the filing, carried by The News Tribune on September 18, 2026. The S-1 named Microsoft and Anthropic as customers and flagged concentration in generic terms, with its largest customer accounting for 52% of first-half revenue; it did not name ByteDance. On filing day, Reuters cited a CNBC estimate valuing Nscale at about $30 billion; once a price range was set, later reporting, including Fortune on September 23, 2026, put the target valuation nearer $35 billion. Fortune also reported that the ByteDance connection, absent from the S-1's customer list, was traced by the Financial Times to a 2025 loan exhibit from Macquarie, not the S-1 itself. Because Nscale is pursuing a U.S. listing, its S-1 sits on SEC EDGAR, which covers only U.S. filings. Segmara does not sell, broker, or arrange purchases of Nscale shares.

Key points
A filed S-1, not a closed IPO
Nscale, a UK-based, Nvidia-backed AI cloud and data-center operator, filed a Form S-1 registration statement with the SEC on September 18, 2026 for a proposed U.S. initial public offering, according to the company's own press release and Reuters' reporting on the filing (carried by The News Tribune) the same day. A filed S-1 is a public disclosure document, not a confidential draft and not a closed deal; it does not by itself set a listing date, an exchange, or a price range, and none of those has been announced.
Because the filing targets a U.S. listing, it sits on SEC EDGAR, which covers only U.S. filings; there is no separate non-U.S. regulator or exchange named in the source material for this offering.
What the S-1 discloses about revenue and customers
Reuters reported that the S-1 disclosed revenue growth of 1,252% in the first half of 2026, to $140.6 million from $10.4 million a year earlier, a scale of increase that is unusual even among fast-growing AI infrastructure providers.
The filing also named Microsoft and Anthropic as customers and flagged customer concentration in generic terms, with the largest customer accounting for 52% of first-half revenue. The S-1 did not name ByteDance as a customer.
Where the $30 billion and $35 billion figures, and the ByteDance link, actually come from
The valuation figure attached to Nscale's IPO has moved between reports. On filing day, Reuters cited a CNBC estimate of about $30 billion. Once a price range was reportedly set in the days that followed, later coverage, including Fortune on September 23, 2026, put the target valuation nearer $35 billion; the higher figure reflects that later stage of the process, not the filing itself.
The ByteDance connection covered in some headlines is not part of the S-1's customer disclosures. Fortune reported on September 23, 2026 that the Financial Times traced the link to a 2025 loan exhibit from Macquarie, meaning it surfaced from a separate financing document, not from the IPO filing's own customer list.

How private-share access starts on Segmara
Nscale filed a Form S-1 with the SEC on September 18, 2026 for a proposed U.S. IPO; no listing date, exchange, or price range has been announced by the company.
Reuters reported the filing disclosed revenue up 1,252% in H1 2026, to $140.6 million from $10.4 million, with the S-1 naming Microsoft and Anthropic as customers and citing a largest customer at 52% of H1 revenue.
The $35 billion valuation figure came from reporting after the filing, including Fortune on September 23, 2026; Reuters' filing-day story had cited a CNBC estimate of about $30 billion, and Fortune separately reported a Financial Times-traced ByteDance connection, sourced to a 2025 Macquarie loan exhibit, not named in the S-1.
Risk notes
Rumor risk: unofficial dates, valuations, or funding details circulating on social media or forums are frequently wrong or outdated and should not be treated as confirmation of anything.
Illiquidity risk: any private-market interest, indicative marks, or pre-IPO share arrangements in a company that has not listed can be difficult to exit and may not reflect a tradable price.
Timing risk: a company can pause, restart, or abandon IPO preparation at any stage, including after a confidential or public filing, so no step before pricing guarantees a listing.

Can retail investors track private-company shares on Segmara?
Yes. Visitors can start with the free Nscale tracker using email only, then decide whether a private follow-up makes sense. Availability, eligibility, pricing, allocation, transfer approval, documents, and final terms can still vary by route.
Why was this market historically hard for retail investors to reach?
Private-company share access has often moved through private equity firms, venture funds, insiders, institutions, and relationship-driven secondary networks. Segmara makes the starting point simpler: visitors can follow named private-company interest before any account, document upload, or payment step.
What is the easiest next step?
Open the free Nscale tracker first. It is email-only and keeps the public step narrow while final availability, pricing, eligibility, and terms are handled only through private follow-up.
Has Nscale confirmed an IPO date?
No. Nscale has filed a Form S-1 with the SEC, a public step toward a US listing, but the filing does not set a specific listing date, exchange, or price range. Track SEC EDGAR and Nscale's own newsroom directly for updates rather than secondary reports.
What is Nscale's IPO valuation?
On filing day, September 18, 2026, Reuters cited a CNBC estimate of about $30 billion. Once a price range was reportedly set, later coverage, including Fortune on September 23, 2026, put the target nearer $35 billion. Neither figure is a locked IPO price; both are estimates from secondary reporting, not the S-1 itself.
How much did Nscale's revenue grow?
According to Reuters' report on the S-1 filing, carried by The News Tribune on September 18, 2026, revenue rose 1,252% in the first half of 2026, to $140.6 million from $10.4 million a year earlier.
Can I buy Nscale shares before the IPO?
Not through Segmara. Segmara is a research site; it does not sell, broker, or arrange purchases of Nscale shares, before or after any IPO. Review the company's public S-1 filing on SEC EDGAR directly.
