Anthropic's commitment of more than $100B over ten years to AWS technologies, announced with Amazon's up-to-$25B investment (amazon-anthropic-investment-2026-04) and up to 5 GW of new Trainium capacity.

Conditions: Includes deployment of up to 5 GW of new Trainium compute capacity for training and serving Claude, with significant Trainium3 capacity expected online in 2026. The 5 GW is an up-to ceiling, so no MW is recorded on this row; the ledger only counts capacity floors.
