Neocloud companies aiming to transform the data center industry face growing challenges as major customers rethink existing agreements amid infrastructure delays and supply constraints. Microsoft recently terminated a lease for computing capacity at a UK data center managed by Neocloud Nscale, a move that highlights the complexities and risks within this emerging sector.

Nscale, which is backed by Nvidia and counts former Meta executives Sir Nick Clegg and Sheryl Sandberg among its directors, had been preparing for a planned initial public offering in New York valued at around $35 billion. The cancellation by Microsoft stems from the Essex data center’s power supply not expected to be operational until after 2030, casting doubt on Nscale’s near-term delivery capabilities.

The decision poses a significant setback not only for Nscale but also for its sector peers, as it underscores the multiple dependencies involved in launching such large-scale neocloud ventures. These businesses require a stable power source, cutting-edge chips, robust infrastructure, and extensive upfront financing, all of which must align to secure long-term contracts. Nscale currently holds contracts valued at more than $100 billion, which represents roughly 40 times its active business value as of late August. Meeting these contract obligations—largely dependent on deploying some 461,000 GPUs, nearly 20 times its present inventory—remains a formidable challenge.

Chip obsolescence further complicates the outlook. Like others in the industry, Nscale plans to redirect outdated chips toward smaller customers or less demanding computational tasks, but there is limited precedent for this approach. Clients are also increasingly cautious, negotiating termination rights to mitigate exposure to potential bottlenecks and delays.

One notable client, AI research lab Anthropic, together with Microsoft, forms a significant part of Nscale’s expected IPO valuation. However, analysts caution that the company’s valuation may be optimistic. Anthropic posted $141 million in revenue during the first half of the year, and while growth projections could suggest full-year sales of approximately $420 million, applying multiples from comparable companies like Nebius and CoreWeave indicates a valuation closer to $6 billion or less—far below Nscale’s targeted $35 billion.

The sector-wide difficulties in delivering on ambitious neocloud promises are shifting business toward established hyperscalers and traditional data center operators, who possess both the capacity and financial resources to meet demand without delays. For large players such as SpaceX and other hyperscalers, these challenges among smaller entrants could translate into new market opportunities.

As the neocloud market seeks to mature, the ability to coordinate power availability, hardware supply, and financing on an unprecedented scale will determine the success of upcoming ventures and the sustainability of current valuations.
