Episode 1 · Anthropic in Talks for Second $45B Compute Deal with Nscale (2026-10-20, 6 posts)

Bloomberg (reporter BTLipschultz), Reuters and the FT, citing sources, report that Anthropic is negotiating a second compute deal worth roughly $45 billion with Nvidia-backed AI cloud provider Nscale to secure more capacity for training and inference. Nothing has been officially announced.

Confirmed

  • The deal is still in negotiation: a new AI cloud compute agreement of about $45 billion between Nscale and Anthropic.
  • It targets a second 460MW building at Nscale's Monarch campus in West Virginia, doubling Anthropic's reservation there to 920MW.
  • The new facility will run Nvidia GPUs (specific models not fully disclosed in the posts).
  • Anthropic already has a prior deal with Nscale; this would be another major compute commitment.

Unconfirmed

  • Final value and signing remain unconfirmed; all figures come from unnamed sources.

Why it matters

  • If closed, it would be another multi-billion-dollar infrastructure deal, underscoring frontier labs' long-term demand for training and inference compute.
  • Commenters (e.g. @inductionheads) joked about whether UK grid capacity could ever power such datacenters, hinting energy infrastructure may be the real bottleneck.

Episode 2 · Nvidia Reportedly to Back $5B-Plus Guarantee for Anthropic Data Center (2026-10-30, 4 posts)

Nvidia is reportedly in talks to guarantee over $5 billion in construction debt for Nscale's 460 MW data center in West Virginia built for Anthropic, aiming to lock in Anthropic's roughly $45 billion Vera Rubin chip order.
