TL;DR
Amazon reported 39% AWS revenue growth in the third quarter, its fastest rate since late 2021, alongside record AWS operating income and a $578 billion order book. But the company spent $75.9 billion on capital investments in the quarter, and its trailing 12-month free cash flow fell to minus $42.4 billion; shares dropped more than 6% in after-hours trading.
Amazon reported that AWS revenue rose 39% to $46.0 billion in the third quarter, its fastest growth since late 2021, while the company spent $75.9 billion on capital investments in the same three months. The cash outlay—primarily tied to AWS and artificial intelligence, according to Amazon executives—left trailing 12-month free cash flow at minus $42.4 billion and helped send Amazon shares down more than 6% in after-hours trading on October 29.
AWS operating income climbed 55% to $17.8 billion, according to Amazon’s earnings release. CEO Andy Jassy said the cloud division’s contracted future revenue, known as its order book, reached $578 billion, up from $496 billion three months earlier. That indicates substantial contracted demand, although the revenue is expected to be recognized over time rather than all at once.
Chief Financial Officer Brian Olsavsky said the quarter’s $75.9 billion in cash capital spending primarily related to AWS and AI. Jassy said most of Amazon’s roughly $220 billion spending plan for 2026 is directed to AWS, and the company expects capital spending to be “meaningfully more” in 2027. Amazon had planned about $200 billion for 2026 in February and raised that figure in July, citing higher memory prices.
Amazon generated $168.3 billion in operating cash flow over the 12 months ending in September, up 29% year over year. Capital spending over that period reached $210.7 billion, up 82%. The resulting trailing 12-month free cash flow was minus $42.4 billion, compared with positive $14.8 billion a year earlier. The source’s estimate for the quarter-only free cash flow is about minus $33.5 billion, calculated from company figures rather than presented as an Amazon-reported metric.
The results also included weaker-than-expected measures outside AWS. Earnings per share were $1.89, below the $1.96 analyst estimate, according to the cited market data. Advertising revenue missed expectations, and Amazon’s holiday-quarter revenue forecast came in slightly below forecasts, CNBC reported. Those results offer another reason investors may have reacted negatively, alongside the scale of spending.

The Cost of Building AWS Capacity
The results put a central question for Amazon investors in focus: how quickly new infrastructure can turn into revenue and cash. AWS is growing rapidly and reports a large contracted backlog, but data centers, servers, chips and related equipment require substantial upfront spending. The gap matters because free cash flow reflects what remains after operating needs and investment, not simply whether the cloud division is profitable.
For cloud customers, the investment is tied to the availability of computing capacity, especially for AI workloads. Jassy said blocks of AI capacity are being reserved well in advance, while short-term access to older AI chips is selling at a premium. Those are company statements about demand and capacity conditions; the figures do not establish how much supply will be available to each customer or when.
The spending also carries consequences beyond AWS. Amazon’s retail and advertising businesses contribute to the overall results investors assess, and this quarter’s reported misses in those areas added to concerns about whether the company can sustain its investment pace while meeting expectations across its business. The market response does not, by itself, show that the investment will fail or that AWS demand is weakening.

From Growth Plan to Cash Outflow
AWS growth has accelerated across six consecutive quarters, according to the source material: 17%, 20%, 24%, 28%, 37% and 39%, from the second quarter of 2025 through the third quarter of 2026, excluding currency effects. The latest result marks a sharp increase from the earlier pace and came with higher operating income. The period covered is July through September 2026.
Amazon’s capital spending has risen alongside that growth. The company’s property and equipment increased from $357.0 billion at the end of 2025 to $508.9 billion at the end of September, a rise of about $152 billion across nine months. Depreciation and amortization—the accounting costs that spread asset costs over their useful lives—rose 25% to $20.9 billion in the quarter. That means equipment purchased now can continue affecting reported expenses in later periods.
Amazon is also developing its own Trainium AI chips and Graviton processors. Jassy said chip-business growth was in triple digits and revenue commitments for both chip lines had grown more than 20-fold in a year. Amazon said customers saved more than $2 billion in the quarter by using its chips; that is the company’s own estimate. It plans to sell Trainium chips outside AWS starting in late 2027, according to the source material.
Jassy argued that owning or securing capacity for the long term can be preferable to renting it from specialized cloud providers, which he said would reduce operating margin by about 35 percentage points. That comparison is an executive’s competitive argument, not an independently established or audited measure. Amazon also announced a $1 billion “Built Together” initiative for communities near its U.S. data centers, including energy and water efficiency upgrades.
“The $75.9 billion of cash capital spending in the quarter “primarily relates to AWS and AI.””
— Amazon CFO Brian Olsavsky
How Fast Spending Pays Back
Amazon has not disclosed a detailed breakdown of the $75.9 billion quarterly spending by data centers, chips, power or other equipment. The company has also not provided a precise timeline for when the new capacity will enter service or how much revenue each part of the build-out is expected to produce.
The $578 billion AWS order book is contracted future revenue, not current-quarter sales or a guarantee that every project will convert on the same schedule. Amazon’s results do not specify how much of that backlog is tied to AI, how quickly customers will use reserved capacity, or how the spending will affect AWS margins over time. The full contribution of the build-out to future cash flow therefore remains unclear.
It is also not possible from the reported results alone to assign the share-price decline to one factor. The source material points to spending and free cash flow, as well as earnings per share, advertising and the holiday-quarter forecast. Amazon has not said how investors should weigh those items against AWS growth.
Watch Holiday Sales and 2027 Investment
Amazon’s next near-term test is the holiday quarter, when investors will compare reported revenue and profitability with the company’s guidance and market expectations. Results should also show whether the non-AWS shortfalls in advertising and earnings per share persist or prove specific to this quarter.
For the longer-term investment picture, investors will be watching updates on AWS growth, contracted revenue, capital spending and free cash flow. Amazon has indicated that 2026 spending will total about $220 billion and that it expects a higher amount in 2027, but has not given a precise 2027 figure. Progress in bringing new AI capacity online—and converting customer reservations into recognized revenue and cash—will help clarify the return on that investment.
Amazon also says it plans to sell Trainium chips outside AWS from late 2027. Further detail on that plan, along with the pace of data-center construction and any new spending guidance, could show whether the company’s chip strategy becomes a revenue source beyond its own cloud services.
Key Questions
How fast did AWS grow in the third quarter?
AWS revenue increased 39% to $46.0 billion in the July-to-September quarter, according to Amazon. The source describes this as the division’s fastest growth since late 2021.
Why did Amazon shares fall after the results?
Shares fell more than 6% in after-hours trading. The source points to the scale of capital spending and negative free cash flow, as well as earnings per share and advertising that missed expectations and a holiday-quarter revenue forecast slightly below expectations. The precise contribution of each factor is not known.
What does Amazon’s negative free cash flow mean?
Free cash flow is generally measured as operating cash flow minus capital spending. Amazon reported minus $42.4 billion over the 12 months ending in September, as capital spending exceeded cash generated from operations over that period. This is a cash-flow measure, not the same as an operating loss.
What does AWS’s $578 billion order book represent?
CEO Andy Jassy said AWS had $578 billion in contracted future revenue, up from $496 billion three months earlier. It represents expected revenue under customer commitments over time; it is not revenue already earned in the quarter.
Will Amazon keep increasing its investment?
Amazon expects about $220 billion in capital spending in 2026 and has said spending in 2027 will be “meaningfully more.” The company has not provided an exact 2027 amount.
