Nscale Files for IPO citing $103 billion AI backlog 

Nscale, which develops and operates AI data centers, is asking public investors to finance one of the fastest and most capital-intensive expansions in the data-center market.

The London-based AI infrastructure company filed a preliminary registration statement Friday for an initial public offering on the New York Stock Exchange under the symbol NSCL. The filing does not say how many shares Nscale plans to sell, the expected price or how much it intends to raise. Those blanks leave the valuation and dilution for later amendments.

Nscale is currently behind to large data center buildouts in West Texas and North Carolina. 

What the IPO filing does provide is a detailed view of a company trying to turn scarce power, long-term customer contracts and massive GPU deployments into a new hyperscale platform.

Nscale reported $140.6 million in revenue for the six months ended June 30, up from $10.4 million a year earlier. It lost $1.02 billion during the same period, including a $457.1 million loss from fair-value adjustments. Its operating loss was $492 million, while its adjusted EBITDA loss was $199.2 million.

The gap between current revenue and promised business is the center of the story. As of Aug. 31, Nscale reported $2.6 billion of active total contract value and $103.4 billion of active and contracted value. The contracts cover about 461,000 active and contracted GPUs and carry a weighted average life of about 5.7 years.

The largest commitments are concentrated among two customers. Microsoft agreements signed between September 2025 and April 2026 provide for payments of as much as $43.8 billion through 2033. Four Anthropic agreements signed in August provide for as much as $44.6 billion. Nscale said it has not obtained binding commitments for the financing required to perform the Anthropic contracts.

That concentration cuts both ways. Long-term take-or-pay agreements can support financing for buildings and equipment. They also tie the economics of a large construction pipeline to a small number of buyers. Nscale’s largest customer generated 52 percent of first-half revenue, down from 73 percent for all of 2025. One customer produced substantially all 2024 revenue.

The company had five active and 12 contracted data-center sites at the end of August, with 1.37 gigawatts of active and contracted capacity. Only about 25,000 GPUs were active. Its larger claim is control of a power portfolio with a path to more than 10 gigawatts, including the Monarch Compute Campus in West Virginia, which Nscale says could scale beyond 6.5 gigawatts of IT load.

This is the power-first model now moving across the data-center sector. Developers are securing electricity, land and interconnection rights before the compute arrives because power has become the hardest part of the project to reproduce quickly. Former bitcoin sites are part of that conversion. Ionic Digital shut down mining at its Ward County, Texas, property and leased the site to Nscale, beginning with 234 megawatts and an obligation to take another 89 megawatts when available.

The strategy is also pushing projects away from the traditional data-center markets and toward places that can offer large blocks of lower-cost electricity. Nscale lists operations or planned capacity in Norway, Iceland, Portugal, the United Kingdom, the United States and Asia-Pacific. Its active capacity remains primarily in leased and colocation facilities, but most contracted capacity is planned for company-owned sites. That shift would give Nscale more control over construction and operating costs while requiring it to carry more development risk.

Smaller developers now describe power rights as their most valuable asset. The expansion has also brought new bottlenecks. Switchgear, transformers and power-distribution equipment can take years to procure, leading operators to finance and order hardware before a tenant begins paying. Grid operators and local governments are responding to the other side of the equation: how much large-load demand can be served, who pays for new generation and transmission, and whether communities should slow approvals while they rewrite their rules.

The filing also shows how much capital must move before those megawatts generate revenue. Nscale spent $3.23 billion on property and equipment during the first half. Construction in progress reached $4.16 billion at June 30. Cash and cash equivalents stood at $1.48 billion, while customer prepayments helped lift deferred revenue to $6.49 billion.

Since June 30, Nscale has used $830 million under a revolving credit facility and entered into another $4.17 billion of financing facilities. Those include GPU loans tied to the Texas and North Carolina deployments. The company expects to fund its commitments with cash, customer prepayments and more debt and equity. Its accountants initially found substantial doubt about its ability to continue as a going concern because the plan depends on uncommitted financing, though management said it could defer, reduce or cancel capital spending if that money does not arrive.

The same pressure is visible across the buildout. Long-lead transformers and switchgear force developers to commit money well before a building is energized. Debt is increasingly structured around tenant contracts, making construction schedules, equipment delivery and customer credit central to the financing rather than secondary operating questions.

Nscale’s portfolio illustrates the financing loop. Customer contracts support project debt and equipment purchases; completed projects are needed to begin recognizing the contracted revenue; and the company needs still more financing to deliver the capacity supporting those contracts. The structure can accelerate construction when every piece arrives on schedule. Delays in power, permits, GPUs or financing can interrupt the entire sequence.

Nscale says it can reduce those risks by controlling more of the stack: power generation, land, data-center design, GPUs and cloud software. It has also agreed to acquire Anyscale, the company behind the Ray distributed-computing framework, moving beyond infrastructure into software and AI services.

Public investors are being offered that vertical-integration thesis before the offering has a price. Nscale says IPO proceeds will support data-center projects, deployments, technology development, working capital and possible acquisitions. Until the company fills in the share count and price range, the filing establishes the scale of the ambition more clearly than the cost of buying into it.
