TL;DR
Amazon reported that AWS revenue grew 39% to $46 billion in the third quarter, its fastest growth rate since late 2021, while AWS operating income rose 55%. The company is investing heavily in data centers, chips and other infrastructure: quarterly cash capital spending reached $75.9 billion, and trailing 12-month free cash flow was negative $42.4 billion.
Amazon’s cloud business accelerated in the third quarter, with AWS revenue rising 39% to $46 billion, while the company’s cash capital spending reached $75.9 billion for the period. The results, reported Thursday, October 29, put the scale of Amazon’s artificial-intelligence and data-center build-out alongside its strongest AWS growth rate since late 2021; Amazon shares fell more than 6% in after-hours trading, according to the source report.
AWS operating income increased 55% to $17.8 billion, according to Amazon’s earnings release. Chief Executive Andy Jassy said the cloud division’s contracted future revenue, known as its order book, rose to $578 billion from $496 billion three months earlier. That is an $82 billion increase in the contracted amount over the quarter, although the commitments are expected to generate revenue 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 capital-spending plan for 2026 is directed to AWS, and the company expects spending to be “meaningfully more” in 2027. Amazon raised its 2026 spending expectation from about $200 billion in July, citing higher memory prices, according to the source material.
The investment is weighing on cash flow. Amazon reported negative $42.4 billion in free cash flow for the 12 months through the third quarter, compared with positive $14.8 billion a year earlier. Over that period, the company generated $168.3 billion in operating cash flow and spent $210.7 billion on capital investment. The source author separately estimates quarterly free cash flow at about negative $33.5 billion; that figure is an author calculation, not a stated company result.
Amazon’s results also included points that fell short of market expectations. Earnings per share were $1.89, below the $1.96 analysts expected, and advertising revenue missed estimates, according to the source report citing CNBC, LSEG and StreetAccount data. Amazon’s revenue forecast for the holiday quarter was slightly below expectations. Those shortfalls, together with the spending outlook, offer context for the after-hours share decline, but do not establish a single cause for the market reaction.

The Cost of Building AI Capacity
Amazon is committing cash now to infrastructure that it expects to support future cloud demand. The scale matters to investors because capital spending is outpacing operating cash generation: the company’s trailing-year investment exceeded operating cash flow by $42.4 billion, the same amount as its reported negative free cash flow. The gap is a measure of current cash use, not proof that the investments will fail to earn returns.
For AWS customers, capacity availability may be as important as headline growth. The source report says large blocks of AI computing capacity are being reserved well in advance, while some short-term capacity on older AI chips is selling at a premium. If demand continues to outrun the pace at which facilities and chips can be brought online, customers may face constraints or higher costs for particular workloads. The report does not quantify those effects across AWS customers.
Amazon’s spending could also influence how cloud providers compete. The company is developing its own Trainium AI chips and Graviton processors as well as operating data centers. Jassy said chip commitments had risen more than 20-fold in a year and that the chip business was growing at triple-digit rates. These are company statements; they do not, by themselves, establish how much customers will use the chips or what financial returns Amazon will earn.

AWS Growth and Spending Timeline
AWS revenue has accelerated across six consecutive quarters, from 17% growth in the second quarter of 2025 to 20%, 24%, 28%, 37% and then 39% in the latest quarter, excluding currency effects, according to the source material. The latest result marks a sharp change from the slower growth rates that had drawn investor attention in earlier periods. AWS remains a major source of Amazon’s operating income, with $17.8 billion reported for the quarter.
The investment is visible in Amazon’s balance sheet as well as its cash-flow figures. Property and equipment rose from $357 billion at the end of 2025 to $508.9 billion at the end of September, an increase of about $152 billion over nine months. Depreciation and amortization, which records the cost of assets over time, rose 25% to $20.9 billion in the quarter. Amazon also reported long-term debt of $173.1 billion, up from $65.6 billion nine months earlier, according to the source report.
The company’s spending includes data-center buildings and equipment, chips, memory and other infrastructure. Jassy said Amazon was “installing an AI accelerator about every 14 seconds.” Amazon also announced a $1 billion “Built Together” commitment for communities near its U.S. data centers, including energy and water-efficiency upgrades. The company did not specify how much of its overall capital spending is allocated to power.
““Primarily relates to AWS and AI.””
— Amazon CFO Brian Olsavsky
Returns and Capacity Remain Unclear
Amazon has not disclosed when the current build-out will translate into cash returns sufficient to offset its spending. The $578 billion AWS order book represents contracted future revenue, but the source material does not provide a schedule for when those commitments will be recognized or how much profit they will generate. The company’s 2027 capital-spending outlook is also qualitative rather than a specific figure.
It is not clear how much the share-price decline reflected spending concerns, the earnings-per-share and advertising misses, the holiday-quarter forecast, or other market factors. Nor does the report provide a full breakdown of capital spending by data centers, chips, power and other equipment. Amazon’s claims about customer savings from its own chips and the margin comparison with rented capacity are company arguments, not independent assessments.
Watch Spending and AWS Conversion
The next milestones are Amazon’s reports on capital spending, AWS revenue and free cash flow, alongside any more specific guidance for 2027 investment. Investors and cloud customers will also be watching whether the contracted backlog converts into reported revenue and whether new infrastructure eases constraints on AI capacity. Amazon has said it plans to sell its Trainium chips outside AWS from late 2027, but the source material gives no further detail on timing, customers or expected sales.
For now, Amazon’s reported results show both sides of its AI push: faster cloud growth and a larger contracted backlog, paired with unusually heavy investment and negative trailing-year free cash flow. The financial impact will depend on how quickly the company can put that infrastructure to work and generate revenue from it.
Key Questions
How fast did AWS grow in the third quarter?
AWS revenue rose 39% to $46 billion in the July-to-September quarter, according to Amazon. The source report says this was its fastest growth rate since late 2021.
How much did Amazon spend on capital investment?
Amazon reported $75.9 billion in cash capital spending during the quarter, primarily related to AWS and AI, according to CFO Brian Olsavsky. The company expects about $220 billion in capital spending for 2026.
What does AWS’s $578 billion order book mean?
It is the contracted future revenue figure Jassy gave on Amazon’s earnings call, up from $496 billion three months earlier. It is not revenue received during the quarter; the commitments are expected to be recognized over time.
Why did Amazon shares fall after the results?
The source report says shares dropped more than 6% in after-hours trading. Amazon’s heavy investment and negative free cash flow coincided with earnings per share, advertising revenue and holiday-quarter revenue guidance that were below expectations. The available information does not establish one definitive cause for the share decline.
Is Amazon’s free cash flow negative?
Yes. Amazon reported negative $42.4 billion in free cash flow over the 12 months through the third quarter, compared with positive $14.8 billion in the prior-year period. This is a historical result and does not establish what future cash flow will be.
