TL;DR
Amazon said AWS revenue increased 39% in the third quarter, its fastest growth since late 2021, while operating income rose 55%. The company spent $75.9 billion in cash capital expenditures during the quarter and reported trailing 12-month free cash flow of negative $42.4 billion, as it expands capacity for cloud and AI demand.
Amazon reported 39% AWS revenue growth for the July-to-September quarter, its fastest pace since the end of 2021, while spending $75.9 billion in cash capital expenditures on data centers, chips and equipment. The company’s trailing 12-month free cash flow fell to negative $42.4 billion, a sharp reversal from a positive $14.8 billion a year earlier, as it builds capacity to meet cloud and AI demand.
AWS revenue reached $46.0 billion, and operating income increased 55% to $17.8 billion, according to Amazon’s October 29 earnings release. The company’s growth rate has accelerated for six consecutive quarters, from 17% to 20%, 24%, 28%, 37% and then 39% since the second quarter of 2025, excluding currency effects, according to the source material. The latest quarter’s figures show that the spending push is accompanying a business that is growing quickly and producing more operating profit.
Amazon’s chief executive, Andy Jassy, said AWS had $578 billion in contracted future revenue, up from $496 billion three months earlier. That order book points to significant customer commitments, but it does not mean all the revenue is collected immediately: the contracts are fulfilled over time, while the infrastructure required to serve them must be financed and built ahead of use.
Chief financial officer Brian Olsavsky said the quarter’s cash capital spending primarily related to AWS and artificial intelligence. Jassy said most of the approximately $220 billion Amazon expects to spend in 2026 is for AWS, and the company expects to spend “meaningfully more” in 2027. The 2026 forecast was raised from about $200 billion in February; Amazon cited higher memory prices when it increased the plan in July, according to the source material.
The spending is weighing on cash generation. Over the 12 months through September, Amazon generated $168.3 billion in operating cash, up 29%, while capital spending reached $210.7 billion, up 82%. Free cash flow—the cash remaining after operating needs and investment—was negative $42.4 billion over that period. The source’s estimate of roughly negative $33.5 billion for the quarter alone is an arithmetic calculation, not a figure identified as Amazon’s reported quarterly measure.
Investors also reacted to results and expectations outside AWS. Amazon reported earnings per share of $1.89, below the $1.96 analysts expected, while advertising revenue missed estimates and the company’s holiday-quarter revenue forecast came in slightly below expectations, according to the source material citing CNBC, LSEG and StreetAccount. Amazon shares fell more than 6% in after-hours trading after the results.

The Cost of Building AWS Capacity
The central tension is a timing gap: Amazon is paying for data centers, computing equipment and chips now, while customers’ contracted use produces revenue over time. The $578 billion order book offers evidence of demand, but contracts do not erase the near-term cash required to build enough capacity to serve customers. If that investment is used and paid for as expected, it can support future cloud sales; the pace and return on that investment remain uncertain.
For AWS customers, capacity availability is a practical consequence of the build-out. Jassy said large blocks of AI computing capacity are reserved well in advance and that short-term capacity on older AI chips is selling at a premium. That suggests some customers may need to plan earlier or pay more for immediate access. Amazon’s expansion is also a competitive choice: it is building and owning or leasing capacity rather than relying heavily on outside infrastructure providers.
For investors, fast AWS growth and rising operating income sit alongside negative free cash flow and a much larger investment bill. That combination makes the scale, duration and eventual returns of the infrastructure program central to judging Amazon’s financial performance. The weaker-than-expected earnings per share, advertising result and holiday-quarter forecast added other sources of concern, so the share-price decline cannot be attributed to the cash-flow figures alone.

From AWS Acceleration to Cash Outflow
The source material describes an extended acceleration in AWS growth, with year-over-year rates rising over six consecutive quarters from 17% to 39%. In the third quarter, the business combined that revenue growth with $17.8 billion in operating income. The current investment cycle is intended to expand the computing and data-center capacity behind cloud services, including infrastructure used for AI workloads.
Amazon says its build-out includes data-center facilities and equipment as well as its own Trainium AI chips and Graviton processors. Jassy said Amazon is installing an AI accelerator about every 14 seconds and described triple-digit growth in its chip business. He also said revenue commitments for Trainium and Graviton had risen more than 20-fold in a year. These are statements from the company’s earnings call, not independent measures of customer savings or future profitability.
Amazon’s property and equipment rose from $357.0 billion at the end of 2025 to $508.9 billion at the end of September, according to figures in the source material. Depreciation and amortization, which spreads the cost of assets across their useful lives, rose 25% to $20.9 billion in the quarter. The source also reports that long-term debt increased from $65.6 billion to $173.1 billion over nine months. Together, these figures show the scale of the infrastructure build and its financial footprint, although they do not by themselves establish the returns Amazon will earn on the assets.
Amazon’s outlook is also shaped by the costs and availability of components. Jassy cited higher memory costs, and the company listed energy prices and supply volatility, including for memory chips, among its risks. Amazon announced a separate $1 billion “Built Together” commitment for communities near its U.S. data centers, including energy- and water-efficiency upgrades. The company did not state what share of its capital spending is devoted to power.
“Amazon expects to spend “meaningfully more” in 2027.”
— Andy Jassy, Amazon chief executive
Returns and Capacity Still Unclear
The results do not establish when the new infrastructure will generate enough cash to offset its cost, or what return Amazon will earn on the investment. The $578 billion order book is a measure of contracted future revenue, but the source material does not provide a schedule for when those contracts will be fulfilled or how much profit they will produce. Amazon has also said it expects 2027 spending to be meaningfully higher, without giving a figure.
Some claims about the economics of the build-out come from Amazon itself. Jassy said customers saved more than $2 billion in the quarter by using Amazon’s chips and argued that renting capacity from specialized providers can reduce a cloud provider’s operating margin by about 35 percentage points. Those figures and comparisons are company claims; the source material does not provide independent verification or details allowing readers to assess them. Amazon has not specified how much of its capital program goes to energy infrastructure, either.
The source identifies several reasons for the after-hours share decline, including the cash spending and free-cash-flow outlook, an earnings-per-share miss, weaker-than-expected advertising and a slightly softer holiday-quarter revenue forecast. It does not establish how much each factor contributed to the market reaction. The availability and pricing of AI capacity may also change as new facilities and chips come online.
Watch Spending and Cloud Demand
The next signals will come from Amazon’s quarterly results and any updates to its capital-spending plans. Investors and customers will be looking for evidence about whether AWS growth remains strong, how quickly new capacity is put into service, and whether operating income and cash generation begin to catch up with investment. Amazon’s stated plan is about $220 billion in capital spending for 2026, with “meaningfully more” expected in 2027.
Customers seeking AI capacity will also have to track availability and pricing as AWS adds infrastructure. Amazon said it plans to sell its Trainium chips outside AWS starting in late 2027, according to the source material; that remains a future plan, not a current product offering. For now, the key unresolved question is whether contracted demand converts into sustained revenue and cash returns at a pace that justifies the continuing build-out.
