Amazon CEO Andy Jassy confirmed that the company's custom silicon business, spanning Graviton CPUs, Trainium AI accelerators, and Nitro virtualization chips, has exceeded a $20 billion annual revenue run rate. The disclosure, from Amazon's Q1 2026 earnings, circulated widely in the AI press this week.
Jassy said the business grew nearly 40 percent quarter-over-quarter and triple-digit percentages year-over-year. He argued that if it sold chips to third parties as standalone vendors do, its run rate would approach $50 billion, placing it among the top three data-center chip businesses globally.
Trainium2 has largely sold out, Trainium3 is nearly fully subscribed at launch, and Trainium4 is already significantly reserved. Amazon holds more than $225 billion in multi-year Trainium revenue commitments.
Anthropic is the anchor customer, having committed to up to 5 gigawatts of Trainium capacity, while OpenAI has committed roughly 2 gigawatts, underscoring how compute access has become a defining competitive variable.
