Multiple news outlets report the deal from sources, but neither party has made an official announcement.
Anthropic stakes $45B on unbuilt West Virginia data hub
Artificial intelligence group Anthropic has agreed to rent computing power from Nscale at a planned site facing environmental hurdles.
In a nutshell
Anthropic agreed to a reported six-year, $45 billion lease for 460 megawatts of capacity at Nscale's planned West Virginia data center to power Nvidia Vera Rubin chips, stepping into space left by Microsoft while taking on execution risks at an unbuilt, off-grid gas facility facing local opposition.
Highlights
- Anthropic agreed to a six-year computing contract with Nscale valued at roughly $45 billion.
- The contract covers 460 megawatts of power capacity to run Nvidia Vera Rubin chips starting in late 2027.
- Nscale's planned Monarch Compute Campus in West Virginia requires between $69 billion and $71 billion to fully build out.
- Microsoft previously stepped away from a letter of intent for capacity at the 1.35-gigawatt site.
From the Editor’s Diary
Securing future computing power now forces artificial intelligence companies to underwrite massive off-grid energy projects, trading grid dependency for severe construction, capital, and local permitting risks.

In short
TL;DR: Anthropic agreed to a reported $45 billion, six-year cloud computing deal with British operator Nscale, taking power from an unbuilt West Virginia site to run future Nvidia chips. The agreement ties Anthropic's computing expansion to an off-grid project facing heavy local pushback and permit hurdles.
Q: What makes Anthropic's $45 billion cloud computing deal significant?
- It secures 460 megawatts of power for next-generation Nvidia chips ahead of an expected stock market listing.
How it unfolded
Bloomberg reveals $45B computing pact between Anthropic and Nscale
Bloomberg reported on August 26, 2026, citing people familiar with the matter, that Anthropic agreed to rent roughly $45 billion worth of computing power from Nscale over six years. The report spread across financial news organizations and social platforms including X.com, revealing Anthropic's push to secure 460 megawatts of power for future Nvidia Vera Rubin processors.
Microsoft exit opens door to contested West Virginia site
Anthropic stepped into the 1.35-gigawatt Monarch campus after software giant Microsoft moved away from an earlier letter of intent for the facility. Subsequent industry reports highlighted that the off-grid site requires an estimated $69 billion to $71 billion to construct with dedicated natural gas power plants, sparking protests from local residents over construction disruptions, flood risks, and air emissions.
Where things stand
The agreement remains an unannounced private deal reported by financial media, leaving payment terms, milestone schedules, and cancellation conditions unconfirmed by Anthropic and Nscale.
Future milestones depend on formal regulatory filings or initial public offering disclosures from both companies, state permit decisions for the on-site gas plant, and Nvidia's manufacturing schedules for volume shipments of Vera Rubin processors.
