Amazon is committing $220 billion to capital expenditures this year, with the vast majority directed toward building data centers for Amazon Web Services. AWS faces a supply crunch: CEO Andy Jassy said the company cannot meet client needs through 2027, and demand for 2028 is already emerging. The division's order backlog reached $496 billion in Q2, up from $165 billion a year earlier.
Amazon stock trades at $249.67. The shares deserve a re-rating based on three factors: accelerating revenue, near-term capacity monetization, and durable competitive moats.
WS revenue accelerated to 37 percent growth in Q2, up from 28 percent in Q1. Operating income from AWS jumped 64 percent year-over-year. This acceleration matters because it proves the capital spending is immediately profitable—not a speculative bet on future demand.
The two-year lag between when Amazon builds data centers and when servers are installed creates a natural supply shortage. As the $220 billion in capacity comes online starting in 2026, AWS will convert its backlog into revenue. Analysts are underestimating the magnitude of that inflection. A conservative model assumes 20 percent of the backlog converts to revenue in 2026–2027. At AWS's current operating margins (32 percent), that backlog represents $32 billion in incremental annual operating income by 2027.
The competitive moat is structural. Clients who build AI workloads on AWS infrastructure face high switching costs. Once an enterprise commits to AWS's ecosystem—training engineers on its tools, integrating with its services, optimizing for its hardware—migration becomes prohibitively expensive. This lock-in effect means AWS's market share gains today translate to durablerevenue streams for decades.
Amazon is funding the build-out through a combination of cash reserves and new debt. Free cash flow has turned negative because capital expenditures now exceed operating cash flow. This is the right trade-off: borrowing at 4–5 percent to capture market share in a sector growing at 30-plus percent annually is rational capital allocation.
