Amazon just quietly became one of the most important chip companies on the planet, and most people missed the memo.

During the company’s Q1 2026 earnings call on April 29, CEO Andy Jassy disclosed that Amazon’s custom AI silicon business has already secured over $225 billion in multi-year revenue commitments. That number, tied almost entirely to Trainium chips, is not a forecast or a wish list. It is contracted demand.

The numbers behind the backlog

The custom silicon unit, which spans Trainium AI accelerators, Graviton CPUs, and Nitro networking chips, is currently running at an annualized internal rate of approximately $20 billion. Jassy suggested that figure could climb to roughly $50 billion if the business operated as a standalone merchant chip company.

The demand driving that backlog is not abstract. Anthropic, which has a multi-year, multi-gigawatt deal tied to over $100 billion in AWS spend, is a major anchor customer. OpenAI has committed to approximately two gigawatts of Trainium capacity. Uber is also adopting both Trainium and Graviton, and Meta has committed to tens of millions of Graviton cores.
