Anthropic, the company behind Claude, is reportedly in talks with AI infrastructure provider Nscale on a second compute agreement worth about $45 billion. The new Anthropic Nscale deal would cover another building at Nscale’s Monarch data center campus in West Virginia. Neither company has confirmed the talks, and people familiar with them say the terms could still change.
What We Know About the Anthropic Nscale Deal
The talks were first reported on October 19 by Bloomberg, which cited people familiar with the matter. Those people stressed that negotiations are still under way, so the size and timing are not final.
If it goes through, this would be the second agreement of roughly the same size between the two companies. They announced their first $45 billion compute deal in recent months, tied to an earlier building at the same campus.
Reuters, which passed along the report, said it could not independently verify the talks. Neither Anthropic nor Nscale had commented publicly at the time.
| Detail | What Has Been Reported |
|---|---|
| Reported deal value | About $45 billion |
| Location | Second building at Nscale’s Monarch campus, Mason County, West Virginia |
| Planned capacity | Roughly 460 megawatts |
| Chips | Nvidia’s upcoming Vera Rubin chips |
| Extra option | Anthropic would get a right of first refusal on a planned third building |
| Status | Talks only; not confirmed by either company |
Where the Anthropic Nscale Deal Would Be Built
Monarch is a multi-phase data center project that Nscale is building in Mason County, West Virginia. According to Nscale, its first phase is designed for 1.35 gigawatts of AI computing capacity, with delivery targeted by early 2028.
The proposed second building for Anthropic would add about 460 megawatts using Nvidia’s next-generation Vera Rubin hardware. That would make it a major piece of infrastructure dedicated to a single customer.
A Setback With Another Big Customer
The report also noted that Microsoft pulled out of a deal at Nscale’s flagship data center after power delays pushed the supply date into the 2030s. That detail is a reminder that big compute contracts depend on things like grid connections, construction and chip deliveries, not just signatures.
Why Anthropic Keeps Buying Compute
Training and running frontier models like Claude takes enormous amounts of computing power. Anthropic has signed a long string of large compute deals over the past year to make sure it has enough capacity for future models and growing demand.
Not everyone is comfortable with this pace. Some investors worry that AI companies are spending too much money for too little profit, though Anthropic has kept pressing ahead with these partnerships.
Timing matters too. Anthropic is expected to go public this year, and you can read more about its revenue and IPO plans in our earlier coverage.
Nscale’s Own IPO Hurdle
Nscale is also preparing to go public. However, it is reportedly facing pushback from investors over its proposed valuation of about $30 billion, which makes a second anchor deal with Anthropic especially valuable for the company.
What This Means for You
If you use Claude for work or personal projects, this deal will not change anything today. It is about computing capacity that may come online years from now, if the talks succeed and construction stays on schedule.
- No instant upgrade: A compute deal does not mean a new Claude model, lower prices or better uptime right away.
- Long-term capacity: More data center space could help Anthropic handle future demand and train larger models.
- Watch the confirmations: The figures are reported, not official, so wait for Anthropic or Nscale to announce terms.
- Do not add it up yet: Treating the two deals as $90 billion already committed would overstate what is confirmed.

The Bigger Picture for AI Infrastructure
Deals like this show how specialized infrastructure firms are competing with traditional cloud giants for AI work. Companies such as Nscale build sites designed around dense GPU clusters, with power and cooling planned from the start.
The key milestones to watch are simple. First comes a signed contract, then financing, construction progress, power hookups and chip deliveries, and finally the date the capacity actually goes live. You can follow every step on our AI news page.

Conclusion
Anthropic and Nscale are reportedly close to a second $45 billion compute agreement for another building at the Monarch campus in West Virginia. The plan reportedly includes about 460 megawatts of Nvidia Vera Rubin capacity and an option on a third building. Nothing is signed yet, and both companies are heading toward IPOs under investor scrutiny. For Claude users, the impact is long term, so the real signal will come when the deal is confirmed and the capacity starts to arrive.
