Arm says Amazon’s Graviton revenue commitments grew more than 20x year over year

Arm Holdings says Amazon’s commitments for its Graviton server processors grew more than 20-fold year over year. That is the kind of growth rate usually reserved for startups, not a chip line inside the world’s largest cloud provider.

The disclosure came alongside Arm’s Q2 FYE27 earnings release on November 4, 2026. It offers one of the clearest signals yet that hyperscalers are moving real workloads onto Arm-based silicon, and moving them quickly.

The numbers behind the chips

Start with Arm itself. The company posted record quarterly revenue of $1.44 billion, up 27% from the same period a year earlier.

Arm credited much of that jump to two things: higher server-related royalties and a growing share of hyperscaler deployments.

The quarter also extended a notable streak. Arm has now delivered five consecutive quarters of revenue growth above 20% year over year.

Then there is Amazon’s side of the ledger. Graviton is the Arm-based CPU that Amazon Web Services designs in-house and rents out to cloud customers.

Beyond the more than 20x rise in Graviton revenue commitments, Amazon’s broader chips business, which also includes its Trainium AI accelerators, grew at triple-digit percentages year over year in Q3 2026. CEO Andy Jassy highlighted the shift toward Arm-based servers during Amazon’s Q3 2026 earnings call in late October.

Customers appear to be getting something out of the switch. Users of Amazon’s custom silicon saved more than $2 billion in Q3 2026, and Graviton offers 30-40% better price-performance than alternative CPUs for certain AI workloads.

How Arm crept into the data center

Arm-based server share at hyperscalers climbed from 15% in 2024 to over 50% in 2025. Arm now expects that share among leading hyperscalers to exceed 60% by the end of calendar 2026, with the ramp of AWS’s Graviton processors doing a lot of the heavy lifting.

Amazon’s strategy also keeps widening. The company plans to make Trainium available outside AWS by late 2027, a move that would take its custom AI silicon beyond its own cloud. That plan reflects strong internal demand as well as customer inquiries.

What this means for Arm, Amazon, and everyone renting servers

For Arm, the story is about the business model as much as the volume. Arm licenses its designs and earns royalties as chips built on them ship. When a hyperscaler like Amazon dramatically scales up commitments for an Arm-based processor, those royalties tend to follow.

The company has already tied its record quarter to server royalties and hyperscaler share gains. If the projected 60%-plus share materializes, the data center becomes an increasingly central pillar of the company’s revenue mix.

For Amazon, custom silicon looks like a competitive moat being dug in real time. Graviton and Trainium let AWS control more of its own hardware stack and pass savings to customers, as the more than $2 billion in Q3 2026 savings suggests. The planned external availability of Trainium hints that Amazon sees its chips as a product in their own right, not just an internal cost tool.

There are risks worth watching. A 20x jump in commitments is a forward-looking signal, and commitments are not the same as recognized revenue on day one. Concentration is another consideration. Arm expects AWS’s Graviton ramp to drive much of its hyperscaler share gain, which ties a meaningful slice of its server momentum to a single customer’s roadmap. Execution on Amazon’s late 2027 Trainium expansion will also shape how far the custom silicon push travels beyond AWS.
