Nscale, the London-based company that rents out AI computing power, is pushing ahead with plans for a public listing, holding meetings with potential investors and preparing to present its case at an investor day in New York next week, according to a report from Sina Finance citing people familiar with the matter.
The company could list as early as this fall, the report said, though it may delay depending on market conditions. Bankers have floated a valuation of about $25 billion, a figure that would mark a sharp step up from the $14.6 billion Nscale commanded when it raised its last funding round in March.
The valuation reflects the scale of the company’s business in a short time. Nscale was founded in 2024, builds and operates data centers packed with Nvidia graphics processors, and rents that computing capacity to customers, most notably Microsoft. The company has signed deals with Microsoft worth roughly $23 billion, according to reports, and it has been a flagship example of AI infrastructure investment in the United Kingdom, with Nvidia itself citing the company as a model for the industry.
The listing preparations have been underway for months. Nscale has hired Goldman Sachs and JPMorgan to manage the offering, according to reports, and it has been building out its executive bench ahead of the scrutiny that comes with public ownership. The investor day next week is part of that preparation, a chance to tell the story directly to the institutions that will decide the valuation.
The company’s pitch rests on a simple proposition: the demand for AI computing exceeds the supply of data centers, and Nscale has locked in the customers and the contracts to prove it. Microsoft’s commitments, which include multi-year agreements to rent Nscale’s capacity, give the company a revenue base that bankers can put in front of investors, a rarity for a two-year-old startup.
The comparison every investor will make is CoreWeave, the first big AI cloud company to go public. CoreWeave’s shares tripled in the months after its March 2025 listing as its contracts with Microsoft and OpenAI looked bulletproof, then swung wildly as the market tested whether the backlog would translate into profit. Nscale’s bankers will argue the company learned from that path; its skeptics will point to the same story as a warning about what AI cloud valuations can do in both directions.
The concentration risk is the obvious objection. Nscale’s revenue depends heavily on Microsoft, and a contract that big can be renegotiated, delayed or canceled. The company’s answer is that its capacity is scarce, its customers have few alternatives, and the AI buildout is early enough that even a partial customer base keeps the business full.
The timing also matters. The IPO market for AI infrastructure companies has been active this year, with data center operators and their suppliers tapping public markets at a steady pace. A listing this fall would place Nscale in that flow, after the summer’s volatile trading in technology stocks and with the AI spending debate unresolved.
The listing would also be a test of how public markets value the middle of the AI infrastructure stack. The companies that own the biggest data centers and the companies that make the chips inside them trade at rich valuations; Nscale sits between them, a tenant’s landlord with a dependence on a handful of customers and the margins that come with scarce capacity. Investors have rewarded that position before, and punished it when the contracts wobbled.
Nscale’s growth has been built on a simple insight: the largest AI companies would rather rent computing than build data centers themselves. Microsoft’s deals with Nscale are part of a strategy of spreading its capacity across providers rather than owning everything, and other cloud customers have followed. That strategy has been good for Nscale’s revenue and, as the March round showed, for its valuation.
The risks are the mirror image of the opportunity. AI computing demand is volatile, contracts have lives of their own, and the cost of the hardware Nscale buys, Nvidia’s latest accelerators and the memory around them, is rising. A company that rents capacity at fixed prices while paying more for the machines underneath is exposed to exactly the squeeze that the industry’s current price increases are creating.
For Nscale’s founder and chief executive, Josh Payne, the listing is the culmination of a two-year sprint. The company he started in 2024 has grown from a startup with a plan to a landlord of the AI economy, and the investor day next week will test whether public investors accept the valuation that private ones did in March. The answer, if the listing proceeds, will come from the market itself.
