Nscale Pre-IPO Disclosure: Microsoft and Anthropic Account for 85% of Total Contract Value
nashnova research
UK data-center developer Nscale disclosed in its US IPO filing that Microsoft and Anthropic together account for roughly 85% of its $103 billion contract backlog — yet only $2.6 billion is actually activated, raising twin questions of customer concentration and execution risk that will test its up-to-$35 billion target valuation.
$103 billion in contracts — why is only $2.6 billion "live"?
Nscale's total contract value stands at $103 billion, but only $2.6 billion was activated as of late August — a gap of over 97%.
This means → the vast majority of contracts are signed but not yet under construction, still far from generating revenue.
The company posted $140.6 million in revenue and a $1.02 billion net loss in the first half of this year — spending far outpaces earnings.
In plain terms = the headline number is enormous, but the cash actually flowing in is tiny, and the burn rate is high.
Two clients make up 85% — where is the risk?
Microsoft signed multiple agreements with Nscale starting late 2025, totaling roughly $43.8 billion through 2033.
Anthropic signed a $44.6 billion deal in August to build server racks and supporting infrastructure at an 8-gigawatt mega-facility in West Virginia.
This means → the two clients account for roughly $88.4 billion — about 85% of total backlog. If either scales back or exits, Nscale's revenue foundation shifts dramatically.
Nscale itself acknowledged in the S-1: "A majority of our revenue is derived from a limited number of customers."
Why is the Anthropic deal the most uncertain?
The contract requires Nscale to hit specific milestones and compute-stability benchmarks; failure to meet them allows termination.
Nscale has not yet secured binding financing commitments for this contract — construction funding remains unresolved.
The first 2 gigawatts of capacity are not expected online until 2028, leaving years of execution risk.
In plain terms = this $44.6 billion deal faces a performance hurdle, a funding gap, and a multi-year wait — three layers of uncertainty stacked together.
Nvidia is shareholder, supplier, and guarantor — what does that mean?
Nvidia is Nscale's largest shareholder and primary chip supplier, and backstops roughly $860 million in lease obligations.
In Nscale's $3.1 billion funding round last week, Nvidia participated, receiving $1 billion in convertible notes or non-voting shares.
This means → Nvidia plays three roles at once — vendor, investor, and guarantor — creating deep mutual dependence.
Yet Nscale's own filing cautions that this tight relationship "does not eliminate supply-chain risk" and that delivery of the latest AI accelerator chips may still face delays.
OpenAI has exited — how is the client map shifting?
OpenAI withdrew in April from its Stargate infrastructure partnership with Nscale in Norway and the UK.
Bloomberg reported that Microsoft took over the Norway project and Alphabet plans to take over the UK project.
Bloomberg also reported that Nscale is in talks with ByteDance on compute-supply arrangements, though ByteDance is not mentioned in the S-1.
This reflects a client roster still in rapid flux — whether new entrants can fill the gap OpenAI left remains unconfirmed.
A $35 billion IPO target — will the market buy it?
The Financial Times reported that Nscale is targeting an IPO valuation of up to $35 billion.
Rothschild-owned Redburn issued a sell rating on Monday for Nscale's listed competitors, citing lease-cost pressure and heavy reliance on debt financing.
Redburn analysts stated plainly: revenue growth is "closely tied to financing availability and should not be taken for granted."
In plain terms = whether Nscale can close the Anthropic contract's funding gap before listing is the critical test of whether its valuation story holds together.
