AWS万亿之路：增速37%但现金流转负，押注企业推理需求

Andy Jassy said AWS has “the potential to be a $1 trillion revenue business.”1

Where Amazon once thought the ceiling was a few hundred billion, it now believes the business “will be at least double that.” AWS finished the quarter at a $169b annualized run rate.

Amazon’s torrid growth fuels the capitalist dream. AWS grew 36.7%, the fastest in 18 quarters & the fifth consecutive quarter of acceleration.2 Five quarters ago it grew 17%; today, 37%.

AWS traces the second steepest trajectory on that chart, 20 points of acceleration over six quarters against Google Cloud’s 54. Azure is close to flat by comparison, adding ten points & sitting at exactly 40% for three consecutive quarters before this one. A 16-point deficit to Azure has narrowed to six.

Microsoft is the fair comparison, because the two pursue similar strategies: neither owns the frontier model, & both sell custom silicon against Nvidia’s margin.

AWS is compounding at 37% from the largest pure-cloud base in the market, & doing it profitably. Operating income grew 64% to $16.6b & margin reached 39.4%, up 650 basis points year over year.21

The forward book tells a less flattering story. AWS closed with $496b of backlog, growing triple digits against $364b three months earlier, & it is the smallest of the triumvirate even though AWS is the biggest business.31

Here Amazon is behind, & the frontier labs are the reason. Microsoft’s $678b is the largest partly because a substantial share traces to OpenAI, whose Azure commitment it locked up early.4 Amazon came later to those deals: Anthropic & OpenAI have since made multi-gigawatt Trainium commitments, but the contracts arrived after Microsoft had already booked its own.1

Like Google, Amazon is funneling every dollar of free cash flow into capital expenditure & borrowing on top of it, diverging from the more cautious Microsoft route. Trailing free cash flow fell from positive $18.2b a year ago to negative $7.6b.5 Alphabet’s turned negative in the same quarter, its first since the 2004 listing; Microsoft’s stayed positive at $19.6b.64 Asked where the capital comes from, Olsavsky noted Amazon has been issuing debt this year.1

Amazon now spends more on infrastructure than the whole company generates in cash.2

Microsoft, facing the same demand, spent $35.8b of cash capex, nearer $41b once finance leases count, & Amy Hood framed the short-lived share as optionality she can throttle. Amazon spent $53.1b & raised its 2026 plan from $200b to $220b, blaming memory prices.41 Microsoft hedges. Amazon does not.

Jassy’s defense of that was unusually specific. Data centers absorb capital two years before earning anything, then last 30 years or more. Servers arrive months before deployment, break even in a little under three years, & carry five-to-six-year lives against AI capacity contracted for at least five years.1

So the trillion rests on one question, & it is not a financing question. Jassy describes AI adoption as barbelled, with the labs consuming “gobs and gobs of compute” at one end & enterprises harvesting cost savings at the other. “In the middle of the barbell,” he said, “is all of the current enterprise production workloads,” most of which do not yet use inference pervasively. That middle “will be the largest absolute segment.”1

Whether it arrives quickly is the wager, & Jassy conceded as much unprompted: “I don’t know if the trajectory of that middle part of the barbell will be the same wildly steep trajectory that we’ve seen with the current barbelled AI Labs piece.”1

If he is right, AWS pushes past the trillion-dollar revenue mark on its own. Amazon trades at about three times sales, so a company pulling AWS along behind it would approach a $10t market capitalization.7

Jassy on the potential for AWS to become “a $1 trillion revenue business” and the upgrade from “a few hundred billion” to “at least double that”; $496b of backlog growing triple digits; revenue growth of 36.7% accelerating for the fifth straight quarter; over $4.6b of sequential revenue added; the $169b run rate ranking 24th on the Fortune 500 as a standalone company; $220b of expected 2026 cash capex raised from $200b on higher memory costs; a two-year data center lead time against 30-plus-year useful lives; less-than-three-year server and networking breakevens against five-to-six-year useful lives; at-least-five-year AI capacity contracts; “if the demand isn’t there, we won’t spend the capital”; insufficient 2026 and 2027 capacity; striking 2028 demand; multi-gigawatt Trainium commitments from Anthropic and OpenAI; the barbell shape of AI adoption with the labs consuming “gobs and gobs of compute,” enterprise production workloads in the middle as “the largest absolute segment,” and his caveat that “I don’t know if the trajectory of that middle part of the barbell will be the same wildly steep trajectory that we’ve seen with the current barbelled AI Labs piece”. Olsavsky, asked by Colin Sebastian about sources of capital for the buildout, on Amazon having issued debt this year and retaining “a lot of options.” Olsavsky on AWS margin up 650 basis points year-over-year, 520 excluding the energy-derivative fair-value gain, and Q2 cash capex of $53.1b. ↩︎ ↩︎ ↩︎ ↩︎ ↩︎ ↩︎ ↩︎ ↩︎ ↩︎

• Microsoft FY26 Q4 earnings release: Microsoft Cloud revenue of $59.3b, up 27%; Azure & other cloud services revenue up 43%; Intelligent Cloud revenue of $39.3b; commercial RPO of $678b; Azure surpassing $100b of annual revenue. Microsoft Q4 cash capex of $35.8b and approximately $41b including finance leases are from the company’s FY26 Q4 materials and call commentary, alongside operating cash flow of $55.4b and free cash flow of $19.6b. Amy Hood disclosed RPO growth of 25% excluding OpenAI against 84% including it; the implied OpenAI share is derived from those two rates rather than separately disclosed. Note that Amazon’s $53.1b is net property & equipment purchases while Microsoft’s figure is cash capex, so the comparison is indicative rather than like-for-like. ↩︎ ↩︎ ↩︎
