Overview
- This week AWS AI chief Peter DeSantis told Bloomberg the company is in early-stage talks to sell Trainium processors and possibly full racks for use in external data centers.
- CEO Andy Jassy has said Amazon’s custom-silicon business already runs at about a $20 billion annual pace and could reach roughly $50 billion if it sold chips outside AWS.
- AWS faces a near-term supply dilemma because current Trainium generations have largely sold out and capacity for Trainium4 is already reserved, leaving little spare foundry capacity.
- Selling chips externally would put Amazon in more direct competition with Nvidia, but AWS chips lack Nvidia’s broad CUDA software ecosystem and will require workload optimization to match price-performance claims.
- Major AI customers already run or plan large Trainium fleets—Anthropic, OpenAI and partners such as Uber—which shows technical viability but also raises questions about how Amazon would balance cloud demand, external sales and foundry allocations.
