Amazon Opens Trainium Lab Doors; Custom AI Chip Wins Over Anthropic, OpenAI, and Apple

TechCrunch published an exclusive tour of Amazon's Trainium chip laboratory, highlighting the custom AI accelerator that has won contracts from Anthropic, OpenAI, and Apple — three of the most significant AI companies now using Amazon's silicon. The Trainium platform represents Amazon's bid to break Nvidia's dominance in AI training hardware. The chip's adoption by competitors who also run on AWS signals a potential shift in the AI compute supply chain, with implications for Nvidia's market position and the broader question of vertical integration in AI infrastructure.
