Key points

  • Nscale filed a Form S-1 and applied to list ordinary shares on the New York Stock Exchange under the symbol NSCL.
  • First-half revenue rose to $140.6 million from $10.4 million, while the net loss widened to $1.02 billion.
  • The filing leaves the number of shares and price range undetermined and highlights substantial customer concentration.

Nscale has filed for an initial public offering in the United States, seeking a New York Stock Exchange listing as investors reassess the economics of rapidly expanding artificial-intelligence infrastructure. The London-based company said on September 18 that it submitted a Form S-1 registration statement to the Securities and Exchange Commission and applied to trade under the symbol NSCL. The number of shares and proposed price range have not been determined, so the filing begins the formal process without establishing how much Nscale will raise or its final valuation.

Revenue rises alongside a larger loss

Nscale reported $140.6 million in revenue for the six months ended June 30, up from $10.4 million in the same period of 2025, according to figures cited from the filing by Reuters. That represents a 1,252% increase. The company's net loss widened to $1.02 billion from $368.9 million. Those figures show how quickly the business has expanded, but they also underline the capital intensity and accounting costs associated with building data centers, securing power and installing advanced computing systems before contracted demand becomes operating revenue.

A large infrastructure pipeline

The company provides computing capacity, power, data centers and software used to train and operate AI models. Reuters reported that Nscale operates across 14 regions, has a power pipeline exceeding 10 gigawatts and has expanded total contracted value to more than $103 billion from $100 million in about two and a half years. A $45 billion agreement for Anthropic to rent capacity from a planned West Virginia campus is among the projects supporting that backlog. Nscale also agreed this week to sell $3.1 billion of convertible bonds, including $1 billion to Nvidia.

Customer concentration is a central risk

The scale of the contracted pipeline does not remove execution risk. Nscale's largest customer generated 52% of first-half revenue, according to the prospectus figures reported by Reuters. Microsoft and Anthropic are expected to become major customers in future periods, leaving results sensitive to a relatively small group of counterparties and to the timing of large facilities. Investors will also have to distinguish contracted value from revenue already earned, while assessing construction schedules, financing needs, power availability and the pace at which new capacity is placed into service.

From crypto mining to public markets

Nscale emerged in 2024 from Arkon Energy, an Australian cryptocurrency-mining group, according to the Financial Times. That origin reflects a broader shift in which power sites and high-density computing expertise developed for bitcoin mining are being redirected toward AI workloads. Nscale is now competing with listed and private infrastructure providers including CoreWeave, Nebius, Crusoe and Lambda. The IPO therefore offers public-market investors another way to evaluate whether demand for scarce computing capacity can support the debt, construction spending and operational complexity required to supply it.

What happens next

Goldman Sachs, J.P. Morgan and Morgan Stanley are the lead bookrunners. Nscale said the offering will proceed only through a prospectus and noted that the registration statement has not yet become effective. The next material disclosures will include the proposed share count, price range and updated financial information. Until those terms are published, comparisons with Nscale's $14.6 billion private valuation from March or reports of a valuation near $30 billion remain indicative rather than final. The offering's reception will provide a fresh test of investor demand for AI infrastructure businesses carrying high growth, heavy financing requirements and concentrated customers.
