Amazon’s custom chip operation just went from side project to serious contender. The company’s Trainium AI training chips are now generating revenue at a $20 billion annual pace, a figure CEO Andy Jassy disclosed during the Q1 2026 earnings call on April 29.

To put that in perspective: if Amazon’s custom silicon division were spun off as a standalone semiconductor company, its total revenue run rate across Trainium, Graviton, and Nitro chips would approach $50 billion. That would place it comfortably among the world’s largest chipmakers.

The numbers behind the silicon surge

The growth here is not incremental. Amazon reported triple-digit year-over-year revenue increases for its custom chip business.

Amazon has locked in more than $225 billion in committed Trainium revenue, anchored by multi-year, multi-gigawatt deals with AI heavyweights Anthropic and OpenAI.
