TL;DR
Amazon reported 39% third-quarter AWS growth and a $578 billion contracted-revenue backlog, while spending $75.9 billion on capital investments during the quarter. Its trailing 12-month free cash flow fell to minus $42.4 billion, and shares dropped more than 6% after hours as investors weighed the AI build-out against weaker-than-expected results and the cash cost of expansion.
Amazon reported 39% growth at Amazon Web Services in the third quarter, its fastest pace since late 2021, while spending $75.9 billion on capital investment during the same three months. The results show the scale of the company’s AI and cloud expansion: AWS operating income rose 55% to $17.8 billion, but trailing 12-month free cash flow fell to minus $42.4 billion, and Amazon shares declined more than 6% in after-hours trading on October 29.
AWS revenue reached $46.0 billion for July through September. Amazon CEO Andy Jassy said the cloud unit’s contracted future revenue, or order book, grew from $496 billion three months earlier to $578 billion. That $82 billion increase points to substantial customer commitments, though the contracts will generate revenue over time rather than immediately.
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 spending plan for 2026 is directed to AWS, and that the company expects capital spending to be meaningfully higher in 2027. Amazon had planned about $200 billion for 2026 in February and raised that estimate in July, citing higher memory prices.
The cash-flow figures show the pressure of paying for infrastructure before it produces its full return. Amazon generated $168.3 billion in operating cash over the trailing 12 months, up 29%, while capital spending reached $210.7 billion, up 82%. The company’s reported trailing 12-month free cash flow was minus $42.4 billion, compared with positive $14.8 billion a year earlier. Long-term debt rose from $65.6 billion to $173.1 billion over the first nine months of 2026.

AI Demand Meets a Cash Cost
Amazon’s results capture a central tension in the cloud industry’s AI expansion: customer demand is accelerating, but serving it requires costly data centers, power, chips and networking equipment well before all that capacity is earning revenue. The $578 billion AWS order book gives the company a large pool of contracted future business, but it does not by itself establish when that revenue will arrive or what margins it will generate.
For investors, the immediate issue is the gap between spending now and cash returns later. AWS’s higher sales and operating income show that the core cloud business is growing profitably, but the overall cash-flow decline makes Amazon’s investment pace and financing needs more prominent. The share-price drop also followed results that missed some expectations: earnings per share were $1.89 against analysts’ $1.96 estimate, advertising revenue missed, and the holiday-quarter revenue forecast came in slightly below expectations, according to the source’s cited analyst data.
For cloud customers, the build-out could mean more available AI computing capacity, but capacity is not necessarily available on demand or at a uniform price. The source reports that 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. Amazon has not provided a full breakdown of how much new capacity is allocated to specific customers or what customers will pay across different services.

How Amazon Is Building Capacity
Amazon’s property and equipment rose from $357.0 billion at the end of 2025 to $508.9 billion at the end of September, an increase of about $152 billion in nine months. Jassy said Amazon is installing an AI accelerator about every 14 seconds. Depreciation and amortization, which records the cost of equipment and other assets over their useful lives, increased 25% to $20.9 billion in the quarter. That means some of today’s infrastructure costs will continue to affect reported expenses in future periods.
The investment includes Amazon-designed chips as well as buildings and equipment. Jassy said the Trainium and Graviton chip businesses are growing at triple-digit rates and that revenue commitments for both rose more than 20-fold in a year. Amazon also said customers saved more than $2 billion in the quarter by using its chips; that figure is the company’s own estimate. AWS’s Bedrock service, which lets customers use AI models from providers including Anthropic, OpenAI and Moonshot, runs mostly on Trainium, according to the source material.
Amazon argues that owning or securing capacity for the long term can be more profitable than renting computing from specialist providers. Jassy said renting from so-called neocloud providers can mean about 35 percentage points less operating margin for a cloud provider. That is Amazon’s competitive argument, not an independently verified margin comparison. The company has also announced $1 billion for communities near its U.S. data centers, including energy and water-efficiency upgrades, but has not disclosed how much of its capital spending is directed to power infrastructure.
“Primarily relates to AWS and AI.”
— Amazon CFO Brian Olsavsky, as quoted in the earnings-call material
Returns and Capacity Remain Unclear
The order book does not reveal exactly when customers will use the contracted capacity, how quickly AWS will recognize that revenue, or what profit margins those contracts will produce. Amazon also has not given a detailed public breakdown of its investment by data-center construction, chips, power and other equipment, leaving the precise allocation of the spending unclear.
Amazon expects 2026 capital spending of about $220 billion and said 2027 spending will be meaningfully higher, but it has not published a specific 2027 figure. The extent to which memory prices, power availability and supply constraints could change those plans is also uncertain. The source reports that Amazon expects to sell Trainium chips outside AWS from late 2027; the scale and commercial terms of those sales have not been provided.
It is also too early to determine from this quarter alone how much of the negative free cash flow reflects a temporary investment surge and how much may persist. The company’s cash-flow measures cover different periods, and the quarterly free-cash-flow estimate cited in the source was calculated by its author rather than stated as a reported company figure. The reported trailing 12-month figure was minus $42.4 billion.
Watch Spending and AWS Returns
Investors and cloud customers will be watching Amazon’s next earnings updates for changes in its capital-spending outlook, AWS growth and free cash flow. The next key evidence will be whether the expanded infrastructure begins producing revenue and operating income fast enough to narrow the cash gap, alongside any updates on customer demand and capacity constraints.
Amazon has indicated that spending will remain elevated, with roughly $220 billion planned for 2026 and higher spending expected in 2027. Further detail on how much of that investment goes to AI infrastructure, and on the timing of additional capacity, would help clarify the financial returns. The company has not set out a specific timetable for free cash flow to return to positive territory.
Key Questions
Why did Amazon shares fall after AWS reported 39% growth?
The source attributes the decline to investor concern about the cash cost of expansion and results that fell short of some expectations. Amazon spent $75.9 billion on capital investment in the quarter, while earnings per share, advertising revenue and its holiday-quarter revenue forecast missed or came in below cited analyst expectations.
How much is Amazon planning to spend on capital investment?
Amazon expects to spend about $220 billion in 2026, with most of that amount directed to AWS, according to CEO Andy Jassy. He said spending in 2027 would be meaningfully higher, but Amazon has not provided a specific figure.
What does AWS’s $578 billion order book mean?
It is the value of contracted future revenue reported by Jassy, up from $496 billion three months earlier. It signals customer commitments, but does not mean Amazon will receive the full amount in the current quarter or that it will all become profit.
Why is Amazon’s free cash flow negative?
Amazon’s investment in infrastructure exceeded the cash generated by its operations over the trailing 12 months. Operating cash was $168.3 billion and capital spending was $210.7 billion; the company reported free cash flow of minus $42.4 billion for that period.
