Nscale's $35 Billion IPO Plan Hinges on Two Big Customers
Nscale Limited filed a registration statement for a proposed initial public offering on September 18, 2026. The London-based firm plans to list ordinary shares on the NYSE, seeking to raise $3 billion at an expected $35 billion valuation. Bloomberg
The filing reports more than $103 billion in contracted value, meaning revenue already promised under contract but not yet earned. About 85% of that total rests on two agreements, a $43.8 billion compute commitment to Microsoft through 2033 and a $44.6 billion supply agreement with Anthropic. TechCrunch
Anthropic's commitment is contingent on Nscale obtaining financing, meaning the deal only stands if Nscale raises the funds. Anthropic also retains the right to walk away from or cancel the deal if Nscale fails to hit milestones described in the filing as stringent. The Microsoft commitment includes delivery of more than 66,000 Nvidia Rubin GPUs, Nvidia's next generation of AI chips, at the Start Campus site in Portugal, announced May 5, 2026.
Current revenue is small compared with those future commitments. Nscale reported revenue of $140.6 million for the six months ended June 30, up from $10.4 million a year earlier. Net losses were $1.02 billion for the same period, up from $369 million a year earlier. Its largest customer accounted for 52% of revenue in the first half of 2026. Reuters
A backlog built on two names
Nscale was spun out of Arkon Energy two years before the IPO filing. Arkon Energy is an Australian cryptocurrency mining company. Nscale now operates data centers in Norway, Portugal, Texas and West Virginia.
Nscale Limited is conducting the offering of ordinary shares with a par value of $0.01 per share, according to the September 18 filing with the U.S. Securities and Exchange Commission. SEC filing
The board includes former Meta executives Sheryl Sandberg and Nick Clegg and former OpenAI executive Fidji Simo. Simo joined September 11, 2026. Nscale acquired Anyscale on July 30, 2026 to enhance its full-stack AI cloud platform, software and hardware offered together for building AI, and signed a strategic partnership with Figure on September 3, 2026 to power physical AI workloads such as robotics.
Nvidia is involved as both supplier and lender. Nvidia agreed to provide $1 billion in convertible debt, a loan that can later convert into shares, as part of a larger $3.1 billion financing deal. Separately, Nvidia is considering investing as much as $10 billion in Anthropic's initial public offering, a transaction that would further link the three balance sheets. Bloomberg
Cash burn meets project finance
The filing lists a series of financings tied to specific sites. Nscale closed approximately $3 billion in financing for AI deployments in Ward County, Texas and Madison, North Carolina, announced August 31, 2026. It closed a $900 million revolving credit facility, a flexible loan a company can draw on and repay as needed, announced July 7, 2026. It secured $790 million in financing to support buildout in Norway announced May 11, 2026.
Nscale was valued at $14.6 billion when it raised a $2 billion Series C led by Aker ASA and 8090 Industries. The IPO expectation of $35 billion would more than double that mark. The IPO proceeds would sit alongside debt tied to specific campuses and GPU tranches, meaning groups of chips delivered over time.
The broader context here is the neocloud funding model. Neoclouds are newer cloud providers built specifically to rent out AI chips. Capacity is sold before it is built. Debt is raised against signed offtake, advance promises to buy that capacity. Construction and GPU procurement consume cash long before utilization payments arrive. Losses widen while contracted backlog grows. Nscale's first-half loss of $1.02 billion against $140.6 million in revenue follows that sequence.
In my view, the term to watch in the S-1 is conditionality. A $44.6 billion agreement contingent on financing creates a circular reference. The customer contract supports the capital raise, and the capital raise is required to preserve the customer contract. Milestone covenants tighten the circle. Failure to deliver on schedule gives the counterparty an exit, which in turn complicates the next debt tranche. That structure can work when execution is clean. It leaves little slack when it is not.
A crowded neocloud field
Nscale lists CoreWeave, Nebius, Lambda and Crusoe as competitors. Customer concentration is common across that group. CoreWeave generates 67% of its revenue from Microsoft. Applied Digital derives 67% of its revenue from Oracle and 30% from CoreWeave.
Worth flagging for enterprise buyers is what concentration means for allocation. When two large buyers account for most of contracted capacity, smaller tenants buy into a roadmap set elsewhere. Pricing, interconnect choices, the links between systems, software stack decisions and expansion sequencing will reflect the needs of the anchor tenants first. The Anyscale acquisition and the Figure partnership suggest Nscale wants a broader platform story around managed inference, running trained models for users, fine-tuning and robotics workloads, but the filing makes clear where near-term capacity is already spoken for.
Looking at what this means for public-market investors, the question is tolerance for duration mismatch. The contracts run to 2033. The GPUs, power contracts and debt payments start now. If Microsoft and Anthropic take delivery as scheduled and Nscale hits its build milestones, the $103 billion backlog converts into a durable, if low-margin, infrastructure annuity, a long-lived stream of payments. If financing tightens or delivery slips, the contingent terms give the largest customers room to pause.
The longer history here is that technology has often rewarded front-loaded builds. Fiber networks, cloud regions and mobile networks all looked over-provisioned before demand arrived. AI training and inference capacity may follow the same path, and the customers underwriting Nscale's expansion have strong incentives to see the capacity completed. The IPO will test whether public shareholders want to fund the interval in between.
