Nscale in talks to sell $45 billion in computing power to Anthropic, a deal that could reshape the AI infrastructure landscape
Key Summary
Nscale, a London AI infrastructure company, is negotiating a deal to sell cloud computing power to Anthropic, valued at approximately $45 billion, which could deepen the reliance on two major customers and raise concerns about the company's execution and financing
Precedent & Market Context
Nscale was founded in 2024 and has raised over $3.7 billion from backers including Nvidia to fund its expansion. The company has pursued facilities powered by renewable energy and in energy-efficient locations like Norway. Recently, Microsoft walked away from a separate Nscale data center project in the UK because power supply delays there were projected to stretch into the 2030s.
Main Event
Nscale, a London AI infrastructure company that didn't exist before 2024, is negotiating to sell cloud computing power to Anthropic in a deal valued at about $45 billion, according to Bloomberg.
The talks, reported on October 19, 2026, center on expanding Nscale's Monarch Compute Campus in West Virginia. That site is already spoken for in a big way.
In August 2026, Anthropic signed a contract with Nscale worth approximately $44.6 billion. It covers 460 megawatts of capacity at Monarch over six years, running on Nvidia's Vera Rubin chips.
For a sense of scale, 460 megawatts is enough electricity to power hundreds of thousands of US homes. The campus has room to grow into multi-gigawatt territory, which is presumably what the new negotiations are about.
Nscale's contracted backlog stood at roughly $103.4 billion as of September 2026. Two customers dominate that pile: Microsoft, at $43.8 billion, and Anthropic, at $44.6 billion.

Analysis & Market Impact
The deal, if signed, would push Nscale's backlog well past its current level. A company targeting a valuation of about $35 billion while holding a backlog north of $100 billion is pitching investors on a very simple idea: the demand is already signed.
With only about $2.6 billion of backlog operational, Nscale is asking the market to trust its execution on a massive build-out. Investors will want to know how it plans to finance construction, how quickly capacity comes online, and what happens if timelines slip.
If two customers already account for approximately 85% of the backlog, adding another giant Anthropic contract would deepen that reliance rather than diversify it.
Implications & Outlook
What to watch next: whether the Anthropic talks produce a signed contract, how Nscale describes the deal in its IPO materials, and progress on the Monarch gas plant. Any update on how much of the backlog moves from paper to operational capacity will matter more than the headline totals.
