TL;DR
Amazon reported 39% third-quarter growth at AWS, its fastest pace since late 2021, and said contracted future revenue reached $578 billion. At the same time, quarterly cash capital spending was $75.9 billion, trailing 12-month free cash flow was negative $42.4 billion, and Amazon shares fell more than 6% in after-hours trading.
Amazon’s cloud business grew 39% in the third quarter, its fastest rate since the end of 2021, but the company’s spending on data centers, chips and other equipment put cash generation under scrutiny. Amazon reported $75.9 billion in cash capital spending for the quarter and negative $42.4 billion in free cash flow over the 12 months through September; its shares fell more than 6% in after-hours trading Thursday.
Amazon Web Services generated $46.0 billion in revenue from July through September, up 39% from a year earlier. Operating income rose 55% to $17.8 billion, according to Amazon’s October 29 earnings release. The company said AWS growth accelerated for a sixth consecutive quarter, from 17% in the second quarter of 2025 to 39% in the latest quarter, excluding currency effects.
Chief Executive Andy Jassy said AWS’s contracted future revenue, often described as its order book, increased to $578 billion from $496 billion three months earlier. That backlog points to substantial contracted demand, but it represents revenue expected over time, not cash already collected. Chief Financial Officer Brian Olsavsky said the quarter’s capital spending primarily related to AWS and artificial intelligence.
Amazon’s trailing 12-month operating cash flow was $168.3 billion, up 29%, while capital spending over the same period reached $210.7 billion, up 82%, according to the figures in the source material. The resulting free cash flow was negative $42.4 billion, compared with positive $14.8 billion a year earlier. Amazon’s quarterly spending reflects payments for long-lived infrastructure whose costs are also recognized over time: depreciation and amortization rose 25% to $20.9 billion in the quarter.
The earnings report also included results investors had reason to weigh beyond AWS. Earnings per share of $1.89 missed the $1.96 analyst estimate cited in the source material; advertising revenue also missed expectations, and Amazon’s holiday-quarter revenue forecast was slightly below estimates. Those items, alongside the cash investment gap, contributed to the negative share-price reaction, though the exact reasons for individual investors’ trading decisions cannot be established from the price move alone.

The Cost of Building AWS Capacity
The figures put a central question for Amazon investors and cloud customers in focus: how quickly can demand turn into revenue and cash after the company pays to build capacity? AWS’s growth and larger order book indicate that customers are committing to future services. But data centers, accelerators, networking equipment and power infrastructure require major spending before the associated capacity can be installed and used.
For shareholders, the gap between cash generated and cash invested affects near-term free cash flow and raises the importance of future returns on that infrastructure. Amazon said it expects about $220 billion in capital spending in 2026 and “meaningfully more” in 2027. That outlook makes the pace of AWS customer adoption, cost control and infrastructure delivery relevant to assessing the scale and duration of the cash outlay.
For businesses buying cloud services, the investment may mean more available AI computing capacity, but supply is not necessarily immediate or evenly distributed. The source reports that large blocks of AI capacity are reserved well in advance and that some short-term capacity on older AI chips is sold at a premium. The report does not provide prices or quantify how broadly customers face those conditions.

A Six-Quarter AWS Acceleration
AWS’s latest growth rate follows a sustained acceleration: the company reported rates of 17%, 20%, 24%, 28%, 37% and 39% over six quarters beginning in the second quarter of 2025, excluding currency effects. The 39% result marks the business’s fastest growth since late 2021, while the 55% increase in AWS operating income indicates that the division’s profit also rose during the quarter.
Amazon has raised its investment plans as it expands infrastructure for cloud and AI workloads. The source says the company had planned about $200 billion in 2026 capital spending in February, then raised that plan in July, citing higher memory prices. Jassy said most of the roughly $220 billion now planned for 2026 is directed to AWS. Amazon has also said it is developing its Trainium AI chips and Graviton processors; Jassy described growth in that chip business, while savings figures attributed to customers are Amazon’s own claims.
The spending has increased the value of Amazon’s property and equipment. The source reports it rose from $357.0 billion at the end of 2025 to $508.9 billion at the end of September. That build-out is part of a wider industry race to supply computing for AI, but Amazon’s results make the company’s own investment pace and cash position the immediate focus.
““meaningfully more””
— Andy Jassy, Amazon chief executive, on the earnings call
Returns and Capacity Remain Unclear
Amazon has not said when the current spending surge will translate into positive free cash flow again, or how much cash each new tranche of infrastructure is expected to generate. The $578 billion order book signals contracted future revenue, but the source material does not detail its delivery schedule, cancellation terms or the share tied specifically to AI services.
The report also does not give a full breakdown of the $75.9 billion quarterly spending by data centers, chips, power, networking or other equipment. Amazon has cited memory costs and supply volatility as risks, but the size and duration of any effect on project costs are not specified. Nor does the material establish how much the after-hours share decline reflected AWS spending versus the earnings, advertising and forecast misses.
Amazon’s long-term debt rose from $65.6 billion to $173.1 billion in nine months, according to the source. That change adds to questions about financing the build-out, but the figures provided do not explain the full causes of the increase or how much new borrowing directly funded capital investment.
Watch Spending and Cloud Delivery
Investors will be watching Amazon’s next quarterly results for updates on AWS growth, operating income, capital spending and free cash flow. The company’s stated plans—about $220 billion in capital spending for 2026 and “meaningfully more” in 2027—set a high investment baseline, although actual spending and the timing of projects may change.
For cloud customers, the next practical signals are whether Amazon brings new capacity online as planned, how it allocates AI computing among customers and what pricing is available. Amazon said it plans to sell its Trainium chips outside AWS beginning in late 2027, but the source material does not provide details about product availability, pricing or customer access.
The next earnings release should clarify whether the order book continues to expand and whether AWS revenue growth can keep pace with the infrastructure being added. Until then, the confirmed picture is one of rapid cloud growth financed by unusually heavy investment, with the timing and scale of the resulting cash returns still unresolved.
Key Questions
How fast did AWS grow in the third quarter?
AWS revenue rose 39% year over year to $46.0 billion in the July-to-September quarter. Amazon said that was its fastest growth rate since the end of 2021.
Why did Amazon shares fall after the results?
Amazon shares fell more than 6% in after-hours trading. The company reported $75.9 billion in quarterly cash capital spending and negative trailing 12-month free cash flow; earnings per share, advertising revenue and the holiday-quarter revenue forecast also missed or came in below analyst expectations cited in the source material. The share-price move alone does not establish how much each factor contributed.
What does Amazon’s $578 billion AWS order book mean?
It is the amount of contracted future revenue AWS said it had, up from $496 billion three months earlier. It signals customer commitments, but it is not cash already received, and the source does not specify when all of that revenue will be recognized.
How much does Amazon plan to spend on capital projects?
Amazon expects about $220 billion in capital spending in 2026 and said it expects to spend “meaningfully more” in 2027. The company said most of the 2026 amount is directed to AWS.
When will Amazon sell Trainium chips outside AWS?
The source says Amazon plans to sell its Trainium AI chips outside AWS from late 2027. Details on availability, pricing and customers have not been provided in the material.
