Amazon Switches On $11 Billion Indiana AI Campus for Anthropic

The purpose-built site runs on Amazon’s Trainium 2 chips in what reporters describe as the largest non‑Nvidia AI cluster.

Overview

  • AWS says seven of a planned 30 buildings are already online, with the campus training models today.
  • Anthropic is running Claude on roughly 500,000 Trainium 2 chips at the Indiana complex.
  • Executives cast the buildout as a strategy to pair proprietary silicon with tailored infrastructure to secure major AI customers.
  • The data center is expected to draw more than two gigawatts of power, and the local utility projects peak demand will roughly double when fully online.
  • Residents and officials near New Carlisle are raising environmental and cost concerns as AWS accelerates expansion.
