Nscale
The $103 Billion Backlog IPO — S-1 filed for NYSE: NSCL, $140.6M of first-half revenue, a $1.02B loss, and an Anthropic contract that is not yet financed.
Nscale is a London-headquartered, vertically integrated AI cloud — land, power, liquid-cooled data centers, NVIDIA GPU clusters and a software layer — that filed a public S-1 on September 18, 2026 to list on the NYSE as NSCL. The prospectus shows a company that has contracted $103.4B of total contract value while recognizing just $140.6M of revenue in the first half of 2026, at a $1.02B net loss. Two customers — Microsoft (up to $43.8B) and Anthropic (up to $44.6B) — account for roughly 85% of that backlog, and the filing states the Anthropic buildout has no binding financing yet. The IPO is a bet on delivery: the backlog is real paper, but only 2.5% of it is active today.
The Numbers at a Glance
1 · Business Overview
Two and a half years from crypto-miner spinout to a $103B backlog
| Metric | Value |
|---|---|
| Launched | May 2024 · spun out of Arkon Energy (Australian bitcoin miner) |
| Founder & CEO | Josh Payne |
| HQ | London, United Kingdom · US agent in Houston, Texas |
| Employees | 1,000+ · ~200 more join with Anyscale |
| Series funding raised | Over $3.3B (S-1) · plus a minimum $3.1B pre-IPO convertible |
| Last private valuation | $14.6B · $2B Series C, March 2026 |
| Active / contracted GPUs | ~25,000 active · ~461,000 active and contracted |
| Capacity | ~1.37 GW active and contracted · ~10 GW power line of sight |
| Data center sites | 5 active · 12 contracted (7 owned, 9 colocation, 1 leased) |
| Weighted average contract life | ~5.7 years, take-or-pay |
| Proposed listing | NYSE · NSCL · ordinary shares of Nscale plc |
Nscale's pitch is full vertical integration: own the powered land, build behind-the-meter generation, design and operate modular liquid-cooled data centers, deploy NVIDIA Grace Blackwell and Vera Rubin clusters, and run a single software control plane over the fleet. Payne's founder letter describes starting the company in August 2023 after "consolidating hundreds of megawatts of land and power in the lowest-cost markets in the world," then going into stealth and launching as Nscale in May 2024.
The footprint sits in renewable-rich, low-cost power regions — Norway, Portugal, Iceland, and selected US and APAC locations — plus the Monarch Compute Campus in Mason County, West Virginia, acquired in March 2026 with a runway the company puts at over 8 GW of gross power. Today most active capacity is colocation and leased; the company says most contracted capacity sits on sites it owns.
2 · Product Suite & Moat
From power to token — and now up the stack with Anyscale
| Layer | What it is | Strategic Role |
|---|---|---|
| Nscale Energy & Power | Power origination, behind-the-meter micro-grids | Cost floor · delivery certainty |
| Purpose-built data centers | Prefabricated, modular, liquid-cooled halls | Speed to capacity |
| Nscale Infrastructure | Dedicated GB300 / Vera Rubin clusters on take-or-pay | The revenue engine today |
| Fleet Operations | Fleet Manager, Control Center, Radar API, observability | Uptime · utilization |
| Nscale Cloud | Bare metal, Slurm, Kubernetes (NKS), serverless inference, fine-tuning | Higher-margin, diversified demand |
| Anyscale (pending) | Commercial platform around open-source Ray | Owns the workload, not just the rack |
The moat thesis the S-1 argues rests on three pillars:
- Power first — access to large contiguous power is, in the company's words, "the primary gating factor for AI infrastructure deployment." Nscale assembled its land and power portfolio from 2022, before it was a separate company.
- Long, prepaid contracts — a 5.7-year weighted average life on take-or-pay terms, and customers prepay heavily: deferred revenue stood at $6.49B on June 30, 2026 ($1.22B current, $5.27B non-current).
- Moving up the stack — the Anyscale acquisition (signed July 28, 2026, closing with the IPO) brings Ray, which the S-1 says has 740 million cumulative downloads, about 174 million of them in Q2 2026.
The counter-argument is that every layer below the software is capital, and every neocloud claims low-cost power. The durable edge has to show up as margin, and it has not yet.
3 · Financials & Unit Economics
Revenue is rising fast; the cost of delivering it is rising faster
These are GAAP figures from the S-1 (US dollars). Fiscal 2025 revenue was $33.0M, up 73% from $19.1M. The first half of 2026 brought $140.6M. The prospectus reports only half-year periods; Bloomberg reported roughly $37M in Q1 and more than $100M in Q2, which would put Q2's annualized run-rate above $400M.
| USD millions | H1 2026 | H1 2025 | FY2025 | FY2024 |
|---|---|---|---|---|
| Revenue | 140.6 | 10.4 | 33.0 | 19.1 |
| Cost of revenue (ex-D&A) | 189.6 | 7.8 | 45.6 | 12.8 |
| Depreciation & amortization | 174.0 | 3.9 | 40.2 | 5.1 |
| Sales, general & administrative | 217.7 | 15.5 | 97.1 | 8.4 |
| Operating loss | (492.0) | (24.7) | (169.8) | (16.1) |
| Loss on fair-value adjustments | (457.1) | (348.9) | (527.8) | (40.2) |
| Net loss | (1,020.1) | (368.9) | (761.8) | (78.2) |
| Adjusted EBITDA | (199.2) | (15.3) | (81.7) | (9.1) |
| Operating cash flow | 1,686.1 | 5.6 | 1,376.4 | (19.2) |
| Investing cash flow | (3,285.8) | (113.7) | (658.5) | (64.2) |
Three things in this table matter more than the growth rate:
- Negative gross economics today. Cost of revenue, before any depreciation, was $189.6M against $140.6M of revenue — 135% of revenue. The company attributes this to fixed costs running ahead of deployments that have not ramped; the S-1 expects margins to rise as contracted clusters come online.
- Nearly half the loss is non-cash marks. The $457.1M fair-value loss — 45% of the H1 net loss — comes from re-marking financial-instrument liabilities to fair value as the valuation climbed. Those instruments convert or are exercised around the IPO, so this line should shrink after listing.
- Customers are financing the buildout. Operating cash flow was +$1.69B in a half-year with a $1.02B loss, because customers prepaid. That is the $6.49B deferred-revenue balance, and it is a liability: it is owed back in delivered compute.
The balance sheet on June 30, 2026: $1.48B cash, $570M restricted cash, $5.73B of property and equipment, $4.07B of goodwill and intangibles (up from $45.5M at year-end, after the first-half acquisitions), and only $137.4M of funded debt. Since June 30 the company has drawn $830M on its revolving credit facility and signed a further $4.17B of financing facilities. It also lists GPU and site facilities including $1.85B at Ward County, $1.2B in North Carolina, $790M at Kvandal South and $331.9M from Macquarie in Iceland.
4 · IPO Status & Timeline
Seven months from confidential draft to public S-1
| Date | Filing / event | Source |
|---|---|---|
| Feb 17, 2026 | Confidential draft registration (DRS) | SEC EDGAR |
| May 12 · Jun 26 · Aug 12, 2026 | Three amended drafts (DRS/A) | SEC EDGAR |
| Aug 21, 2026 | Bloomberg reports a US IPO raising up to ~$3B | Bloomberg |
| Sep 4, 2026 | Bloomberg reports talks for ~$3.5B of pre-IPO financing | Bloomberg |
| Sep 15, 2026 | Subscription agreement: minimum $3.1B convertible, including $1.0B from NVIDIA | S-1 |
| Sep 18, 2026 | Public S-1 · NYSE: NSCL · price range blank | SEC EDGAR |
Filing status is grounded directly in EDGAR, not in aggregator copy. The registrant is Nscale Ltd, CIK 0002110365 (SEC file 333-299011), an England and Wales company that will re-register as Nscale plc before listing. The S-1 cover leaves the price range, share count and offering size blank, so no IPO valuation has been set. The only priced mark remains the $14.6B Series C. Goldman Sachs, J.P. Morgan and Morgan Stanley are lead bookrunners, with RBC, BofA, Deutsche Bank and eight more bookrunners behind them. Insiders face a 180-day lock-up. Nscale is an emerging growth company and a non-accelerated filer.
NVIDIA's $1.0B converts into non-voting shares
On September 15, 2026, three days before the public filing, Nscale signed subscriptions for at least $3.1B. That is $2.1B of unsecured convertible loan notes plus a further $1.0B that NVIDIA will take as notes or Non-Voting Shares. The notes convert automatically at the IPO. The NVIDIA leg closes around November 16, 2026, so its form depends on whether the IPO prices first.
- After listing, the company will have one class of voting ordinary shares, one vote each. NVIDIA's economic stake is structured as Non-Voting Shares.
- Holders of 5% or more named in the S-1: Aker (via Aker DC Holding), Sandton Capital Partners, and Paladin Capital, a trust vehicle for which Josh Payne is the settlor. Percentages are blank until pricing.
- The board includes Sheryl Sandberg, Nick Clegg, Susan Decker, Fidji Simo and Aker CEO Øyvind Eriksen.
Timing: a public S-1 normally prices within weeks once a range is added by amendment. Watch for the S-1/A with a price range; that is the first document that implies a valuation.
5 · Competitive Landscape
The listed neocloud pack
| Company | Ticker | Market Cap | Latest revenue anchor | QL Signal |
|---|---|---|---|---|
| Nscale | NSCL (filed) | $14.6B (private mark) | $140.6M · H1 2026 | — |
| CoreWeave | CRWV | $46.0B | $2.58B · Q2 2026 | Underweight |
| Nebius Group | NBIS | $56.9B | Foreign filer · not in SEC XBRL | Underweight |
| IREN | IREN | $16.8B | $707M · FY to Jun 2026 | Buy |
| NVIDIA (supplier, investor) | NVDA | $5.17T | — | Neutral |
| Microsoft (customer) | MSFT | $3.64T | — | Neutral |
Market caps and QuantLogix signals are from the QuantLogix universe as of September 18, 2026. Revenue anchors come from each company's SEC XBRL filings. Private peers named in Nscale's positioning include Lambda, Crusoe and Voltage Park.
The closest analogue is CoreWeave. It listed in March 2025 on a similar story: large take-or-pay contracts, one dominant customer, and NVIDIA as supplier and shareholder. It now reports $2.58B a quarter. Nscale's contracted backlog of $103.4B is large enough to put it in that class. Its recognized revenue is about 3% of CoreWeave's: $140.6M against $4.65B in the first half of 2026.
6 · The Backlog: Microsoft, Anthropic & Figure
$103.4B contracted — 85% from two customers
| Customer | Contract value | Where / what | Timing |
|---|---|---|---|
| Microsoft | Up to ~$43.8B | Statements of work signed Sep 2025–Apr 2026; 12,600+ GB300 GPUs at SINES (Portugal) building 1, 66,000+ Vera Rubin NVL72 at the new 200 MW SIN02 site | Through Dec 2033; Vera Rubin from late 2027 |
| Anthropic | Up to ~$44.6B | Four tranches of dedicated Vera Rubin NVL72 capacity at the Monarch campus, West Virginia | Signed Aug 25, 2026; multi-year per tranche |
| Figure AI | Not disclosed | Up to 100,000 Vera Rubin GPUs; Nscale also invests in Figure | First GPUs from H2 2027 |
| Other customers | ~$15.0B (residual) | Remainder of the $103.4B contracted TCV | — |
The Anthropic contract is signed — its financing is not
The S-1 is explicit: the Anthropic agreements require Nscale to use best efforts to secure financing for the GPUs and data center within a set period, and "as of the date of this prospectus, we have not obtained binding commitments for any of the financings required to fund performance under the Anthropic Services Agreements." The agreements give "only limited relief" for supply-chain delays. If Nscale misses a tranche's delivery date, Anthropic may terminate that tranche without liability.
- The Monarch campus is designed for an initial 2 GW of gross power (1.37 GW of IT load) by the first half of 2028, rising to about 8 GW gross by 2031. The buildout comes before most of the revenue.
- Nscale bought the Monarch site's owner, AIPCorp, in March 2026 for $792.6M: $99.6M in cash and $693.0M in Series C shares.
- Bloomberg reported in August that Microsoft had exited a non-binding letter of intent for Monarch's first phase before Anthropic signed. The S-1 does not mention a Microsoft arrangement at Monarch.
Customer concentration: the largest customer was 52% of H1 2026 revenue, 73% of FY2025, and substantially all of FY2024.
7 · Valuation Framework
52× today's revenue, 0.8× tomorrow's — the whole debate is delivery
Until the S-1/A adds a price range, the only priced reference is the $14.6B Series C. Priced against what Nscale earns today, that looks expensive. Priced against what it has contracted, it looks cheap. Both readings come from the same filing:
| Lens | Revenue base | Multiple of $14.6B |
|---|---|---|
| H1 2026 annualized | $281M | 51.9× |
| Full-delivery contracted run-rate ($103.4B ÷ 5.7 yrs) | ~$18.1B / yr | 0.8× |
| CoreWeave, market cap ÷ Q2 2026 annualized | $10.3B | 4.5× |
| IREN, market cap ÷ FY to Jun 2026 | $707M | 23.8× |
A way to frame an IPO valuation: how much of the $18.1B contracted annual run-rate is Nscale credibly delivering, priced at CoreWeave's 4.5×? This measures what the market pays for delivered revenue. It ignores the debt and dilution needed to build the capacity, which will be large.
| Delivered share of contracted run-rate | Annual revenue | Implied value at 4.5× |
|---|---|---|
| 10% · Microsoft phases only, on schedule | ~$1.8B | ~$8.1B |
| 25% · Microsoft plus first Anthropic tranches | ~$4.5B | ~$20.2B |
| 50% · Monarch financed and ramping on time | ~$9.1B | ~$40.5B |
The $14.6B private mark sits between the first two rows. It implicitly prices in delivery of about 18% of the contracted run-rate at a CoreWeave multiple. An IPO range well above that would be pricing in the Anthropic financing before it exists.
8 · Key Risks
What public-market diligence will price in
| Risk | Severity | Evidence / Mitigant |
|---|---|---|
| Anthropic financing not committed | High | No binding financing as of the S-1; missed tranches are terminable without liability |
| Execution at gigawatt scale | High | 25,000 of ~461,000 GPUs active; Monarch's first 2 GW is not due before H1 2028 |
| Customer concentration | High | Microsoft plus Anthropic ≈ 85% of contracted TCV; top customer 52% of H1 revenue |
| Negative unit economics today | Medium | Cost of revenue is 135% of revenue before D&A; the company expects margins to improve as clusters ramp |
| Capital intensity and dilution | Medium | $3.29B H1 investing outflow; $4.17B of new facilities since June; Anyscale paid partly in equity |
| Supplier dependence | Medium | Three suppliers were 53%, 37% and 10% of H1 2026 purchases; NVIDIA is also an investor |
| Material weaknesses | Medium | Weaknesses in internal controls, IT general controls and finance staffing; remediation under way; KPMG auditor since 2026 |
| GPU obsolescence | Medium | 5.7-year contracts on 2027-vintage Vera Rubin; the company plans phased refresh cycles |
9 · Pre-IPO Exposure Routes Today
Indirect vectors before NSCL prices
| Route | Link to Nscale | Purity |
|---|---|---|
| Aker ASA (Oslo Børs) | 5%+ holder via Aker DC Holding; led the Series B and co-led the Series C | Medium |
| NVIDIA (NVDA) | Series B/C investor, $1.0B pre-IPO convertible, and the GPU supplier | Low |
| Dell (DELL) · Nokia (NOK) | Series B and C participants | Low |
| Microsoft (MSFT) | Largest customer, not a disclosed holder | Low |
| Secondary SPVs | EDGAR shows Form D feeder vehicles named for Nscale (2024–2026), including one series of 8090 Industries, the Series C co-lead | Medium |
| The IPO itself | NYSE: NSCL once the S-1/A sets a range and the registration goes effective | Direct |
None of the listed routes gives meaningful exposure. Nscale is a rounding error inside NVIDIA, Dell or Nokia. Aker has the largest relative exposure among the listed holders, but it is a diversified industrial holding company. For most investors, the practical entry point is the IPO book or the first weeks of trading.
Bottom Line
Nscale arrives at the public market with the biggest backlog-to-revenue gap of any AI infrastructure IPO so far: $103.4B contracted, $140.6M recognized in H1 2026, and a $1.02B half-year loss. The contracts are real and the counterparties are the best in the industry. Customers prepaying $6.49B is a strong signal that they want this capacity. But the equity story rests on building gigawatt-scale campuses on time, starting with an Anthropic contract whose financing the S-1 says has not been committed. Price the IPO against delivered revenue, not signed paper. The $14.6B Series C already credits roughly 18% delivery at a CoreWeave multiple. The first data points that change the thesis are the S-1/A price range, a binding Monarch financing, and the first Vera Rubin clusters going live in 2027. Until then, this is a watchlist name with a wide range of outcomes, and the book is where the valuation discipline has to happen.
