Nscale files for a $35 billion IPO, testing Wall Street's appetite for concentrated neocloud and GPU-cloud infrastructure bets.

Nscale, a London-based AI cloud company, filed for a NYSE listing on September 18 under the ticker NSCL. The company is seeking to raise as much as $3 billion while asking investors to value it at up to $35 billion—more than double the $14.6 billion valuation it achieved after closing its Series C round earlier this year. Goldman Sachs, J.P. Morgan and Morgan Stanley are underwriting the deal.

The financials tell a sobering story. In the first half of 2026, Nscale generated $140.6 million in revenue while spending $189.6 million to deliver it, resulting in a loss exceeding $1 billion despite 1,252% year-over-year sales growth. More troubling still, Nscale's S-1 filing disclosed substantial doubt over its ability to continue as a going concern. The company concluded it could manage this risk by delaying planned capital spending—a scenario where the company essentially acknowledged to regulators that it nearly ran out of money.

Founded in 2024 by Josh Payne, who spun out the company from Melbourne-based crypto miner Arkon Energy, Nscale has expanded rapidly. It operates AI data center hubs in Norway, Portugal, Texas and West Virginia and claims control of more than 10 gigawatts of power capacity. Nvidia has been a consistent backer since the Series B and participated in a $3.1 billion convertible note sale on September 15, investing roughly $1 billion itself. Dell, Nokia, Citadel, Jane Street and Lenovo are also investors.

The company's primary argument to public markets rests on its backlog. Nscale reports more than $50 billion in contracted revenue, including a $45 billion multi-year compute agreement with Anthropic tied to its Monarch Compute Campus in West Virginia. The filing lists remaining performance obligations at $56.4 billion spread across seven years. If half converts to revenue on schedule, the current losses appear temporary. If it does not, the debt load remains indifferent to that distinction.

Nscale is not the first company to make this pitch. CoreWeave went public in March 2025 at $40 per share and nearly quadrupled to a peak of $183.58 by June before falling roughly 60% from that high, struck by a guidance cut tied to data center construction delays and investor concerns over its debt-heavy expansion and dependence on a handful of major customers.

The core bet underlying every neocloud IPO is the same: these companies lease GPUs—primarily Nvidia's—to firms that develop chips and models. It is a picks-and-shovels business that only works if AI infrastructure spending continues accelerating at its current pace.

The going-concern language is the detail that should concern buyers most. Companies burn cash pursuing growth constantly. Those that disclose to the SEC that they doubted their own survival, then resolve it through a spending delay rather than new revenue, are wagering as much on their runway as on market conditions. Nscale's backers are betting that $51 billion to $56 billion in contracts will outrun the debt and burn rate before it matters. Wall Street will now decide whether it agrees.
