1Dual Megadeals in Negotiation

Anthropic is in advanced discussions with UK infrastructure startup Nscale for a second computing deal potentially worth $45 billion. This follows an existing $44.6 billion agreement between the two firms. The proposed contract covers a 460-megawatt facility at Nscale's Monarch campus in West Virginia as due diligence continues.

2Capacity-as-a-Service Structure

Under the proposed framework, Anthropic is purchasing computing capacity rather than leasing physical real estate. Nscale will own, finance, and operate the data centre facility alongside its processors. Anthropic pays only as computing power comes online, while also holding a right of first refusal on a third campus building.

3Vera Rubin Chip Architecture

The planned West Virginia site will deploy Nvidia's next-generation Vera Rubin artificial intelligence chips to train and run Claude models. Nvidia is also an equity investor in Nscale, having participated in its recent $3.36 billion pre-IPO funding round alongside Third Point, Apollo Global Management, and Citadel.

4Aggressive Multibillion Infrastructure Spree

The ongoing discussions expand Dario Amodei's strategy of locking down massive, diversified computing pipelines ahead of Anthropic's own potential IPO. Beyond Nscale, Anthropic has secured a $50 billion deal with Fluidstack, a $45 billion agreement with SpaceX, and a $10 billion contract with Volta Infrastructure Holdings.

5Severe Revenue Customer Concentration

Despite rapid expansion, Nscale's financials highlight significant reliance on single clients. ByteDance accounted for 73% of Nscale's $33 million revenue last year. In the first half of 2026, Nscale generated $141 million in revenue but reported a net loss of $1 billion amid heavy capital expenditure demands.

6Uncommitted Financing and Exit Clauses

Nscale's public September filing revealed that it lacked binding debt or equity commitments to fund the construction required for the initial Anthropic contract. Crucially, Anthropic retains the contractual right to withdraw from the partnership entirely if Nscale misses specified project financing deadlines.

7Valuation Pushback Stalls Listing

Nscale is targeting an IPO valuation between $30 billion and $35 billion, but Bloomberg reports investor pushback over the figure. The startup has not started formal roadshow marketing while responding to SEC comments, as market participants scrutinize debt leverage across the capital-intensive data centre sector.

8Execution Risks in AI Compute

The massive scale of compute commitments illustrates both surging generative AI demand and rising investor anxiety around capital efficiency. Nscale must prove it can secure capital, complete construction, and energize sites on schedule, while Anthropic assumes substantial performance risks across its multi-provider infrastructure network.
