TL;DR
Amazon reported third-quarter AWS revenue growth of 39% and a record $578 billion order book, but its cash capital spending reached $75.9 billion for the quarter. Shares fell more than 6% in after-hours trading as investors weighed the AI infrastructure build-out against negative free cash flow and results that missed some expectations.
Amazon reported 39% third-quarter revenue growth at AWS on October 29, its fastest rate since late 2021, while spending $75.9 billion in cash capital expenditure during the quarter. The combination—rapid cloud growth and a costly AI infrastructure build-out—was followed by a more than 6% drop in Amazon shares in after-hours trading, as investors considered how quickly today’s investment can generate cash.
AWS revenue reached $46.0 billion for the July-to-September quarter, and operating income rose 55% to $17.8 billion, according to Amazon’s results. CEO Andy Jassy said AWS had $578 billion in contracted future revenue, up from $496 billion three months earlier. That order book represents contracted business to be delivered over time; it is not revenue already received.
Chief Financial Officer Brian Olsavsky said the quarter’s cash capital expenditure primarily related to AWS and AI. Jassy said most of Amazon’s roughly $220 billion 2026 spending plan is directed to AWS, and the company expects spending to be “meaningfully more” in 2027. Amazon had raised its 2026 plan from about $200 billion in July, citing higher memory prices, according to CNBC’s reporting.
The cash-flow picture was sharply weaker than the revenue growth. Amazon reported 12-month free cash flow of minus $42.4 billion, compared with positive $14.8 billion a year earlier. Over the same 12-month period, operating cash flow was $168.3 billion and capital spending was $210.7 billion. Those figures reflect spending on assets such as data centers and equipment, which are paid for before their capacity can produce revenue.

The Cost of Building AI Capacity
The results illustrate the tension facing large cloud providers: demand for AI computing is rising, but meeting it requires substantial upfront investment in data centers, chips and related infrastructure. Amazon’s order book and AWS growth point to strong customer commitments, while its negative free cash flow shows that those commitments do not remove the near-term cost of building capacity.
For cloud customers, the spending may mean more available computing capacity over time, but the timing and price of access remain relevant. The source report says large blocks of AI capacity are being reserved in advance and that short-term capacity on older AI chips is selling at a premium. Those details were not presented as a general price schedule, and Amazon has not disclosed how much of its capital spending goes specifically to power or other infrastructure components.
Amazon’s investment choices also affect investors beyond AWS. The company’s retail and advertising businesses help fund the wider operation, and the report says earnings per share, advertising revenue and holiday-quarter revenue guidance fell short of analyst expectations. That combination gives investors two issues to track: whether cloud growth continues and whether spending translates into returns without weighing too heavily on cash generation.

How Growth Turned Into a Cash Gap
AWS’s reported growth has accelerated over six consecutive quarters, from 17% to 39% since the second quarter of 2025, excluding currency effects, according to the source material. The latest figure is a substantial change in the pace of Amazon’s cloud business, which supplies computing and related services to companies and other customers.
Amazon is investing in both facilities and its own chips. The source report says property and equipment rose from $357.0 billion at the end of 2025 to $508.9 billion at the end of September. Jassy said Amazon was installing an AI accelerator about every 14 seconds. He also said commitments for its Trainium AI chips and Graviton processors had risen more than 20-fold in a year. These are company statements; the report does not provide independent verification of the chip-commitment figure.
Amazon says customers saved more than $2 billion in the quarter by using its own chips. That is a company-reported estimate, not an independently established measure in the supplied material. Amazon has also said it plans to sell Trainium chips outside AWS from late 2027, which could extend the business beyond cloud services. Meanwhile, depreciation and amortization rose 25% to $20.9 billion in the quarter, reflecting the way the cost of equipment is recorded over time.
When Spending Produces Returns
Amazon has not specified when its current investment wave will translate into stronger free cash flow, or how quickly the contracted AWS demand will become recognized revenue and cash receipts. The $578 billion order book is a measure of contracted future revenue, but the source material does not give a schedule for when that business will be delivered or the margins it will earn.
The breakdown of spending is also incomplete. Company executives said most planned 2026 expenditure is for AWS and that the quarter’s spending primarily related to AWS and AI, but Amazon did not disclose a precise allocation among data centers, chips, energy and other equipment. It is also unclear how persistent higher memory costs and power constraints will be, or what effect they will have on construction timelines and operating costs.
The source material estimates quarterly free cash flow at roughly minus $33.5 billion by arithmetic, rather than identifying that as a directly reported quarterly figure. That estimate should be distinguished from Amazon’s reported 12-month free cash flow of minus $42.4 billion. The reasons for the share decline also cannot be reduced to one factor: the report points to heavy spending as well as weaker-than-expected earnings, advertising and holiday-quarter revenue guidance.
Spending Plans and Holiday Demand
Investors will be watching Amazon’s next earnings update for changes to its capital-spending outlook, the pace of AWS growth and evidence that new capacity is being used and generating revenue. The immediate spending guide is about $220 billion for 2026, with Amazon expecting meaningfully higher spending in 2027, according to Jassy’s comments in the source material.
The holiday quarter will also test the company’s retail outlook. Amazon’s revenue forecast for that period was slightly below analyst expectations, while earnings per share and advertising also missed estimates, according to the source report’s references to CNBC, LSEG and StreetAccount data. The supplied material does not give the exact forecast or estimates, so those comparisons cannot be quantified here.
Further developments to track include Amazon’s planned external Trainium sales from late 2027 and whether AI capacity remains booked well ahead of deployment. Until the company provides more detail on investment returns, spending allocation and capacity utilization, the central question remains how quickly its contracted cloud demand can support the cash required to build out the infrastructure.
Key Questions
How fast did AWS grow in the third quarter?
AWS revenue rose 39% year over year to $46.0 billion for July through September, according to Amazon’s report. The company described this as its fastest growth rate since late 2021.
Why did Amazon shares fall after the results?
Shares fell more than 6% in after-hours trading. The source report points to the scale of Amazon’s investment spending and negative free cash flow, alongside earnings per share, advertising and holiday-quarter revenue guidance that were below analyst expectations. The material does not establish a single cause for the share move.
What does AWS’s $578 billion order book mean?
It is the value of contracted future revenue cited by CEO Andy Jassy, up from $496 billion three months earlier. It does not mean Amazon has already collected that amount, and the source does not specify when the contracts will be delivered or recognized as revenue.
How much is Amazon planning to spend on capital investment?
Amazon’s 2026 capital-spending plan is about $220 billion, with most of it expected to go to AWS, according to Jassy. He said spending in 2027 would be “meaningfully more,” but the source material does not provide a specific 2027 total.
What remains uncertain about the AI build-out?
The timing of returns, the detailed allocation of spending and the pace at which new capacity will produce cash remain unclear. Amazon has reported strong AWS demand, but the order book alone does not show when that demand will translate into recognized revenue or positive free cash flow.
