TL;DR
Amazon said AWS revenue increased 39% in the third quarter to $46 billion, its fastest growth rate since late 2021, while its contracted order book reached $578 billion. The company spent $75.9 billion on cash capital expenditures during the quarter; trailing 12-month free cash flow fell to minus $42.4 billion, and Amazon shares dropped more than 6% in after-hours trading.
Amazon said AWS revenue rose 39% to $46.0 billion in the third quarter, its fastest growth since late 2021, as the cloud unit’s contracted future revenue climbed to $578 billion. The results came with a sharp increase in investment: Amazon spent $75.9 billion in cash capital expenditures during the quarter, and its shares fell more than 6% in after-hours trading on Thursday, October 29.
AWS operating income increased 55% to $17.8 billion, according to Amazon’s October 29 earnings release. The company said AWS had accelerated revenue growth for six consecutive quarters, from 17% in the second quarter of 2025 to 39% in the latest quarter, excluding currency effects. Chief Executive Andy Jassy said the AWS order book reached $578 billion, up from $496 billion three months earlier. That figure represents contracted future revenue, not cash already received.
Chief Financial Officer Brian Olsavsky said the quarter’s cash capital spending was primarily related to AWS and artificial intelligence. Amazon’s cash spending on capital expenditures was $75.9 billion for the three months, according to the supplied report. The company expects capital spending of about $220 billion in 2026 and said it anticipates spending meaningfully more in 2027. Jassy said most of the planned 2026 amount is for AWS.
The spending has outpaced cash remaining after investment. Amazon’s trailing 12-month free cash flow was negative $42.4 billion, compared with positive $14.8 billion a year earlier. Over the same 12-month period, the company generated $168.3 billion in operating cash flow and spent $210.7 billion on capital expenditures. The source estimates quarterly free cash flow at about negative $33.5 billion using its own arithmetic; Amazon’s reported trailing-period figure is the clearer company-level measure.
Other results and guidance also weighed on investor reaction, according to the source material. Earnings per share of $1.89 fell short of the cited analyst estimate of $1.96; advertising revenue missed expectations, and Amazon’s holiday-quarter revenue forecast was slightly below expectations. The supplied account says shares declined more than 6% in after-hours trading, but does not establish how much of the move was driven by each factor.

AI Capacity Comes With a Cash Cost
The results show the trade-off facing Amazon as it expands infrastructure for cloud and AI customers: AWS demand is growing quickly, but building the capacity requires large outlays before all of that capacity produces revenue. The $578 billion order book points to substantial contracted demand ahead, while the negative free-cash-flow figure shows the near-term financial burden of meeting it.
For AWS customers, the scale and timing of construction can affect whether computing capacity is available when needed and what it costs. The source says large blocks of AI capacity are being reserved well in advance and that short-term capacity using older AI chips can command a premium. These are statements in the supplied report, not quantified company-wide pricing data. Amazon’s investments also matter to shareholders because equipment, facilities, energy and financing costs can affect cash generation for years, even as new capacity supports future sales.
Investors’ response reflected more than AWS growth alone. The earnings-per-share shortfall and weaker-than-expected advertising and holiday-quarter revenue guidance provided additional concerns, according to the source material. The share-price decline does not by itself establish how investors weighed those factors against the cloud results.

A Faster Cloud Growth Streak
AWS’s 39% growth marks a sharp acceleration from the 17% rate reported in the second quarter of 2025. The sequence cited in the source is 17%, 20%, 24%, 28%, 37% and 39% across six successive quarters, excluding currency effects. The latest result places cloud growth at its fastest pace since the end of 2021, according to the supplied report.
Amazon has increased its investment forecast as the build-out has grown. The company planned about $200 billion in 2026 in February, then raised that figure in July, citing higher memory prices, the source says. Its property and equipment rose from $357.0 billion at the end of 2025 to $508.9 billion at the end of September. Those balances describe the value of assets on the books, rather than cash spending in a single quarter.
Amazon is investing in data centers and equipment as well as its own processors, including Trainium AI chips and Graviton processors. Jassy said revenue commitments for the chips had grown more than 20-fold in a year and described the chip business as growing at triple-digit rates. These are company statements; the source does not provide independent verification or a detailed breakdown of the commitments. Amazon also said customers saved more than $2 billion in the quarter by using its chips, a company estimate.
Open Questions on Returns and Capacity
Amazon has not provided a precise timeline in the supplied material for when the expanded capacity will generate cash returns or how much of the spending will be allocated to individual data centers, chips, power and other equipment. The company has not said how much of its investment goes specifically to energy. Its $578 billion order book is a measure of contracted future revenue, but the source does not detail delivery schedules, customer concentration, cancellations or the margin expected from those contracts.
The negative quarterly free-cash-flow estimate in the source is an author’s calculation, not a separately stated Amazon figure. The reported figure is negative $42.4 billion over the trailing 12 months. It is also unclear from the supplied material how the holiday quarter will affect cash generation or whether the 2027 spending outlook will change. Amazon’s statements about customer savings from its chips and the margin impact of renting capacity from other providers are company claims rather than independently established comparisons.
Watch Spending and Holiday Results
The next indicators are Amazon’s holiday-quarter results and any updated guidance on capital spending, AWS capacity and cash flow. The source says Amazon expects about $220 billion of capital spending in 2026 and meaningfully more in 2027, so future updates will show whether that plan holds and how quickly new facilities and equipment are put to work.
Investors and cloud customers will also be watching for more detail on how quickly AWS converts its order book into recognized revenue, whether AI capacity remains constrained, and whether the investment begins to narrow the gap between operating cash generation and capital expenditures. The supplied material does not give dates for additional company guidance or a later earnings release.
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, Amazon reported. The supplied report describes this as the unit’s fastest growth since late 2021.
How much did Amazon spend on capital expenditures?
Amazon spent $75.9 billion in cash capital expenditures in the third quarter, according to the source material. Its stated 2026 plan is about $220 billion, with meaningfully higher spending expected in 2027.
What does AWS’s $578 billion order book mean?
Amazon CEO Andy Jassy said AWS had $578 billion in contracted future revenue, up from $496 billion three months earlier. It is a measure of contracted revenue expected in the future, not money already collected; the supplied material does not give a schedule for when it will be recognized.
Why did Amazon shares fall after the results?
The supplied report says Amazon shares fell more than 6% in after-hours trading. It points to negative free cash flow and the scale of investment, as well as earnings per share below the cited analyst estimate, an advertising shortfall and holiday-quarter revenue guidance slightly below expectations. The source does not quantify the contribution of each factor to the share-price move.
Was Amazon’s free cash flow negative for the whole year?
Amazon’s trailing 12-month free cash flow was negative $42.4 billion, compared with positive $14.8 billion a year earlier, according to the supplied figures. That is a rolling 12-month measure, not a forecast of full-year results. The report’s estimate for the quarter alone is its own calculation.
