Amazon’s chip business scale

Amazon’s most valuable chip business may be the one most people never noticed, because Amazon built it first to cut its own cloud costs instead of selling boxes like Nvidia. In his April 9, 2026 shareholder letter, Andy Jassy said Amazon’s chips business is now running above $20 billion a year. (aboutamazon.com) That business is three different pieces of Amazon Web Services hardware, and each one does a different job inside the cloud. Graviton is the central processor for general computing, Trainium is the artificial intelligence training chip, and Nitro is the networking and security card that offloads infrastructure work from the main server. (aboutamazon.com) (aws.amazon.com) Graviton is Amazon’s way of replacing a big chunk of the standard server brain with its own version. Amazon said in 2023 that it already offered more than 150 Graviton-based cloud instance types, had built more than 2 million Graviton processors, and had more than 50,000 customers using them. (businesswire.com) Trainium is aimed at the expensive part of artificial intelligence where companies teach giant models on huge piles of data. Amazon says first-generation Trainium instances can cut training costs by up to 50% versus comparable Amazon cloud instances, which is why Amazon keeps pitching it as a cheaper alternative to Nvidia-heavy systems. (aws.amazon.com) (cnbc.com) Nitro is less famous, but it may be the reason Amazon can even run cloud servers at this scale. Amazon calls Nitro the card that handles networking, storage, and security outside the main processor, which frees the main server to do customer work instead of cloud housekeeping. (aboutamazon.com) The speed of the jump is what startled investors. Jassy said the same chips business was above $10 billion when Amazon reported fourth-quarter 2025 results, and by April 2026 he said it had already doubled to more than $20 billion and was still growing at triple-digit year-over-year rates. (theinformation.com) (aboutamazon.com) Amazon is also signaling that demand is outrunning supply, which is unusual language for an internal infrastructure program. Data Center Dynamics reported on April 10, 2026 that Jassy said two large Amazon Web Services customers asked whether they could buy every Graviton instance available in 2026. (datacenterdynamics.com) The next clue is that Amazon is treating these chips less like plumbing and more like products. The Information reported on April 10, 2026 that Amazon is considering selling its chips beyond Amazon Web Services, which would move it closer to the model used by standalone semiconductor companies. (theinformation.com) That is where the $50 billion idea comes from. Jassy wrote that if Amazon monetized these chip assets more fully, including selling them more directly to others, the business could be worth as much as $50 billion in annual revenue. (aboutamazon.com) Amazon has played this game before, just not with chips. What started as internal software and server infrastructure for Amazon’s own retail business became Amazon Web Services, and that cloud division turned into one of the company’s biggest profit engines. (aboutamazon.com) The tension now is that Amazon’s chips are most useful when they make Amazon Web Services cheaper and faster than rivals. The moment Amazon sells too much of that advantage outside its own cloud, it risks turning a secret weapon into a normal supplier business. (aboutamazon.com) (thenextweb.com) For now, Amazon is trying to do both at once: keep the chips inside Amazon Web Services to win cloud customers, while hinting that the same hardware could one day stand on its own. A business that started as a way to avoid paying other chipmakers is now large enough for Amazon’s chief executive to describe it as a potential $50 billion company inside the company.
