Nscale Loses Microsoft Before IPO, Valuation Wobbles

Executive Signal Summary

Microsoft has withdrawn as anchor tenant from Nscale's first UK data center in Loughton, Essex, where it planned to rent 23,000 Nvidia AI chips. This setback precedes Nscale's New York IPO under ticker NSCL, targeting a valuation of about $30 billion, but investors value the company at only $16-19 billion. Nscale's financials show H1 revenue of $140.6 million against a net loss of approximately $1 billion. Microsoft accounts for over 40% of Nscale's order backlog of $103 billion, though only $2.6 billion is from active contracts. Nscale asserts the relationship remains strong and is seeking alternative power sources, as grid delays may persist until the 2030s. The company faces broader industry challenges, with rivals like Firmus canceling IPOs and expectations that only 7-10 neoclouds will survive.

Nscale Files for US IPO Targeting $30B Valuation

British AI infrastructure company Nscale has filed its IPO prospectus with the US SEC, aiming to list on the New York Stock Exchange under the ticker 'NSCL'. The company seeks a valuation of around $30 billion, as reported by CNBC via Reuters, a significant jump from its last private round valuation of $14.6 billion. Nscale, which transitioned from Bitcoin mining to AI compute, reported first-half 2026 revenue of $140.6 million, a 1,252% increase, but also a net loss of $1.02 billion. Its order book stands at $103.4 billion, with Microsoft and Anthropic contracts totaling $88.4 billion. The company recently secured $3.1 billion in convertible notes, with Nvidia as a key investor. Nscale faces high customer concentration, a going-concern note, and dependence on a few suppliers. Goldman Sachs, J.P. Morgan, and Morgan Stanley are lead underwriters.

Nscale's IPO tests Wall Street's appetite for concentrated AI bets

British neocloud Nscale is preparing for an IPO on the NYSE, targeting a $35 billion valuation and raising $3 billion. The company, spun out of Arkon Energy two years ago, has over $103 billion in contracts, with 85% from two clients: Microsoft ($43.8 billion) and Anthropic ($44.6 billion). The Anthropic deal depends on Nscale securing financing and meeting milestones. Nscale reported $140.6 million revenue for H1 2026, up from $10.4 million, but net losses widened to $1.02 billion. Nvidia is in talks to guarantee billions in debt financing for Nscale's West Virginia data center for Anthropic, covering construction and electricity costs. This support extends Nvidia's ~$170 billion in investments and credit to neoclouds, including $1 billion to Nscale in September. The project will use Nvidia's Vera Rubin chips. The IPO tests investor appetite amid high customer concentration and AI spending concerns.

Aker CEO dismisses Microsoft Nscale contract loss as minor

The CEO of Aker ASA, Øyvind Eriksen, the largest investor in UK AI infrastructure startup Nscale, downplayed Microsoft's withdrawal from a data centre deal as a "minor contract". Speaking during Aker's Q3 results presentation, Eriksen reassured investors ahead of Nscale's planned US IPO targeting a $35bn valuation. He noted that since Nscale's Series C funding round, the company's activity and contract portfolio more than doubled, and the termination was expected. Microsoft cancelled the deal to lease compute capacity from Nscale's Essex data centre due to anticipated power supply issues. Nscale is reportedly close to a new multibillion-dollar deal with Anthropic, which would increase its commitment in West Virginia. Aker owns approximately 23% of Nscale, valued at $3.31bn based on the Series C valuation.
