TL;DR
Amazon said AWS revenue rose 39% in the third quarter, its fastest growth since late 2021, while the cloud unit’s operating income climbed 55%. The company also reported $75.9 billion in quarterly cash capital spending and trailing 12-month free cash flow of minus $42.4 billion, as it builds capacity for expected cloud and AI demand.
Amazon reported 39% third-quarter revenue growth at Amazon Web Services, its fastest rate since the end of 2021, while spending $75.9 billion in cash capital expenditures during the quarter. The results, reported October 29, put the scale of the company’s AI and cloud build-out alongside a sharp cash-flow reversal: trailing 12-month free cash flow was minus $42.4 billion, compared with positive $14.8 billion a year earlier.
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. The supplied report says AWS growth has accelerated for six consecutive quarters, from 17% to 39% since the second quarter of 2025, excluding currency effects. Amazon chief executive Andy Jassy said the AWS order book—contracted future revenue—grew to $578 billion from $496 billion three months earlier.
The spending is being directed primarily toward AWS and artificial intelligence, according to chief financial officer Brian Olsavsky. Jassy said most of Amazon’s roughly $220 billion 2026 capital-spending plan is intended for AWS, and that the company expects to spend “meaningfully more” in 2027. Amazon had planned about $200 billion for 2026 in February and raised that estimate in July, citing higher memory prices, according to the supplied source.
Amazon generated $168.3 billion in operating cash over the 12 months through the third quarter, up 29%, while capital spending over the same period reached $210.7 billion, up 82%. The resulting trailing free cash flow was negative. The source estimates quarterly free cash flow at about minus $33.5 billion, based on its own arithmetic; that figure should be treated as an estimate rather than a directly stated company result. Amazon’s property and equipment rose from $357.0 billion at the end of 2025 to $508.9 billion at the end of September.
The report also identifies weaker-than-expected results outside AWS as part of the market reaction: earnings per share of $1.89 missed analysts’ $1.96 estimate, advertising revenue missed expectations, and Amazon’s holiday-quarter revenue forecast was slightly below forecasts, based on CNBC, LSEG and StreetAccount figures cited in the source. Amazon shares fell more than 6% in after-hours trading, according to the report.

The Cost of Building AI Capacity
The figures show a widening timing gap between the cost of constructing cloud infrastructure and the revenue it may generate over time. Amazon is paying for data centers, chips, equipment and other capacity now; contracted customers generally use that capacity and pay for services over a longer period. The $578 billion order book is a measure of contracted future revenue, not cash already received, and does not by itself establish when that revenue will be recognized or how profitable it will be.
For investors, the key issue is whether AWS growth and future earnings can justify the scale of investment. Amazon’s cloud unit is expanding quickly and reporting higher operating income, but company-wide free cash flow has turned negative as investment rises. The supplied report says long-term debt increased from $65.6 billion to $173.1 billion over nine months; it does not provide a full breakdown of how much of that change financed the build-out. Investors must weigh the expected returns against financing needs, higher equipment costs and the possibility that demand or delivery schedules change.
For cloud customers, the build-out could affect the availability and price of computing capacity. Jassy said large blocks of AI capacity are being reserved well in advance and that short-term capacity on older AI chips is selling at a premium. Those are executive statements, not independent market measurements in the material provided. Amazon’s investment matters beyond its retail business because AWS supplies computing services to organizations that rely on cloud infrastructure for software, data and AI workloads.

AWS Demand Meets Long Build Times
Amazon’s results follow a period of accelerating AWS growth. The supplied source lists six consecutive quarterly growth rates—17%, 20%, 24%, 28%, 37% and 39%—starting in the second quarter of 2025 and excluding currency effects. The latest quarter’s result therefore extends an existing rise rather than representing a single isolated jump. The company’s $82 billion increase in its order book over the quarter is another indicator of contracted demand, although the source does not give a schedule for when those contracts will convert into sales or cash.
Amazon is investing in both facilities and its own computing hardware. Jassy said the company installs an AI accelerator about every 14 seconds and that revenue commitments for its Trainium AI chips and Graviton processors had grown more than 20-fold in a year. Amazon also said customers saved more than $2 billion in the quarter by using its own chips; that is a company claim, not an independently verified saving in the supplied material. Jassy said most of AWS’s capacity is owned or leased on a long-term basis. His comparison that renting from specialist cloud providers would reduce operating margin by about 35 percentage points is also an executive claim, not an audited industry-wide measure.
The spending carries costs beyond the initial construction and equipment purchases. Amazon reported depreciation and amortization of $20.9 billion in the quarter, up 25%, reflecting the accounting cost of assets spread over their useful lives. The company has also pointed to higher memory costs and supply volatility as risks. It announced a $1 billion “Built Together” initiative for communities near its U.S. data centers, including energy and water-efficiency upgrades; the supplied source does not say how much of its overall capital budget is allocated to power or utilities.
“Amazon expects to spend “meaningfully more” in 2027.”
— Andy Jassy, Amazon chief executive
Returns and Cash Timing Remain Open
Amazon’s results establish the pace of spending and AWS growth, but they do not show exactly when the new capacity will produce revenue and cash, or what returns each investment will earn. The $578 billion order book represents contracted future revenue, but the supplied material does not specify its duration, cancellation terms, customer concentration or expected margins. It also does not establish how much of the current build-out is already matched to customer commitments.
The company’s figures and executive comments do not settle how much of the spending is driven by AI workloads compared with broader cloud expansion, or how memory, electricity and construction costs may change. The source gives no detailed allocation for power infrastructure. Amazon’s stated customer savings from Trainium and its margin comparison with rented capacity are company claims; independent verification is not included in the material.
The earnings miss and below-expectation holiday-quarter revenue forecast are cited in the source, but it provides no detailed figures for the advertising shortfall or the forecast range. It is also not clear how much the after-hours share decline reflected the cash-flow outlook versus the earnings and revenue misses. The supplied article gives a debt increase but not a full account of its causes, funding mix or repayment schedule.
Watch Spending and Holiday Sales
The next near-term test is Amazon’s holiday-quarter performance against its revenue forecast and investor expectations. Results from retail and advertising will help show whether weakness outside AWS persists, while AWS growth and operating income will indicate whether cloud demand continues to support the investment program.
Investors will also be watching for updates to Amazon’s 2026 capital-spending outlook, its expectation of meaningfully higher spending in 2027, and the trajectory of free cash flow. Further disclosures about AWS capacity, customer commitments, memory and power costs, and the timing of infrastructure coming online would help clarify when the current cash outlays may begin producing returns. Amazon has said it plans to sell Trainium chips outside AWS from late 2027, according to the supplied source; that remains a future plan, not a current source of revenue.
Key Questions
How fast did AWS grow in the third quarter?
AWS revenue rose 39% to $46.0 billion in the July-to-September quarter, according to Amazon’s results. The supplied report describes this as the fastest growth since the end of 2021.
Why did Amazon’s free cash flow turn negative?
Amazon’s cash capital spending rose sharply as it invested in data centers, chips and equipment. Over the 12 months through the third quarter, the company generated $168.3 billion in operating cash and spent $210.7 billion on capital expenditures, leaving trailing free cash flow at minus $42.4 billion.
Does the $578 billion AWS order book mean Amazon has received that money?
No. The figure is contracted future revenue, according to CEO Andy Jassy. It is not cash already collected, and the supplied source does not provide a timetable for when the contracts will turn into recognized revenue or cash.
What did Amazon say it plans to spend on capital investment?
Amazon expects about $220 billion in capital spending in 2026 and said it anticipates “meaningfully more” in 2027. Jassy said most of the 2026 amount is intended for AWS.
What remains unknown about the AI spending?
The supplied material does not detail when each new facility will enter service, the returns expected from individual projects, or how the $578 billion order book is distributed across customers and time. It also does not give a complete breakdown of spending on power, memory and other infrastructure.
