Amazon’s AI Resurgence: AWS & Anthropic’s Multi-Gigawatt Trainium Expansion

What happened

AWS is constructing over a gigawatt of new data center capacity, anchored by Anthropic, to host a cluster of nearly one million Amazon Trainium2 AI chips. This massive infrastructure build-out represents a significant demand signal for the semiconductor supply chain, particularly for AI accelerators and their associated components. Bullish: The multi-gigawatt expansion by a major hyperscaler indicates sustained, high-volume demand for advanced AI chips and supporting memory/packaging.
