AWS triples its Nvidia commitment to 3M GPUs — the 1M order ran out early

AWS and Nvidia announced 2 million additional GPUs — Blackwell Ultra, Rubin and Rubin Ultra — for deployment across 2027–2028, taking the committed total from more than 1 million to more than 3 million. The earlier 1M commitment, made at GTC 2026 for deployment starting this year, was exhausted ahead of schedule. The deal also covers 100,000 GPUs of secure AI-factory capacity for the US government.

Largest cluster on custom (non-GPU) AI silicon

Reached

AWS (Project Rainier) / Anthropic — AWS activated Project Rainier — nearly 500,000 of its own Trainium2 chips across multiple US data centers, one of the world's largest AI compute clusters and the biggest built on custom silicon rather than Nvidia GPUs. Anthropic trains and serves Claude on it (>5x its previous training compute), scaling toward 1M+ Trainium2 chips — a proof point that frontier-scale compute can run on a hyperscaler's in-house accelerators.
