The trillion-dollar cloud is a migration story, not an AI one

Corporate America is shipping its data centers to the cloud in the same way it once shipped them to office basements: first, and without much ceremony. The growth underneath Andy Jassy's $1 trillion AWS thesis is the move of existing workloads off premises, payroll systems, retail backends, scoring engines for a traveling golf tour, not a sudden AI capex binge. Companies move first, then stack AI on top. The flywheel follows.

That sequence is what the latest quarter actually shows. AWS revenue rose 37.6% year over year to $42.2 billion, its fastest in 18 quarters and a fifth straight quarter of acceleration. Customer backlog sits at $496 billion. Amazon raised 2026 capex to $220 billion to build for it. The mechanism is migration: roughly 85% of global IT spending is still on-premise, and Jassy is betting that the next two decades flip that ratio.

David Provan, the PGA Tour's vice president of digital architecture, describes what the flip looks like in practice. "The PGA Tour is a traveling circus. We don't play inside a set of white lines." The tour used to ship its own servers on trucks to every tournament, plug them in, and rip them out on Sunday night. It now runs on AWS. That is the unit of the trillion-dollar bet: a Fortune 500 enterprise giving up its data center for a rented one, and trusting that the cloud will follow it to the next course.
