TL;DR
Amazon reported that AWS revenue grew 39% year over year in the third quarter, its fastest pace since late 2021, while operating income rose 55%. The company also reported $75.9 billion in quarterly cash capital spending and negative trailing 12-month free cash flow; shares fell more than 6% in after-hours trading as investors weighed the investment bill and results that missed some expectations.
Amazon said AWS revenue grew 39% year over year to $46.0 billion in the third quarter, its fastest growth pace since late 2021, even as the company spent $75.9 billion on capital investments in the quarter. Amazon shares fell more than 6% in after-hours trading on October 29, as investors weighed the scale of its data-center and AI build-out against negative free cash flow and results that missed some expectations.
AWS operating income rose 55% to $17.8 billion, according to Amazon’s October 29 results. Chief Executive Andy Jassy said the AWS contracted order book reached $578 billion, up from $496 billion three months earlier. That figure represents future contracted revenue, not cash already collected, and the timing of customer payments depends on delivery and usage.
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 had raised its 2026 plan from about $200 billion in July, citing higher memory prices, according to the source report.
Amazon’s free cash flow over the 12 months ending in the third quarter was negative $42.4 billion, compared with positive $14.8 billion a year earlier. Over the same 12-month period, operating cash flow was $168.3 billion and capital spending was $210.7 billion. Those figures show how investment outlays exceeded cash generated by operations, although free cash flow is a company-defined measure. The report also cited quarterly earnings per share of $1.89, below analysts’ $1.96 estimate, and a holiday-quarter revenue forecast slightly below expectations.

The Cost of AWS Capacity
The results put the tension in Amazon’s AI strategy in clear view: demand for AWS capacity is rising, but building the infrastructure to serve it requires large amounts of cash before all the contracted revenue arrives. The $82 billion increase in AWS’s order book during the quarter points to customer commitments, while the negative free-cash-flow figure shows the near-term financing burden of expanding capacity.
For cloud customers, the spending could mean more access to computing resources as new data centers and chips come online. But Amazon has said some AI capacity is reserved well in advance, and short-term access to older AI chips is being sold at a premium. The results do not specify how quickly new capacity will become available or how pricing will change.
For investors, AWS growth and profitability are strong, but the broader quarter also included missed earnings and advertising expectations and a softer-than-expected holiday revenue outlook. The after-hours decline indicates that market reaction reflected more than cloud growth alone; the scale and timing of investment, alongside other business results, were also in focus.

AWS Growth and Investment Plans
Amazon’s reported AWS growth accelerated for six consecutive quarters, from 17% to 39% between the second quarter of 2025 and the third quarter of 2026, excluding currency effects, according to the source material. The current quarter’s growth is therefore part of a sustained acceleration rather than a single-quarter change.
Amazon says its infrastructure spending buys data-center buildings and equipment as well as its own chips, including the Trainium AI accelerator and Graviton processor. Jassy said Amazon was installing an AI accelerator about every 14 seconds. The company also said customer use of its chips saved more than $2 billion in the quarter; that is an Amazon estimate, not an independently verified figure. Amazon plans to sell Trainium chips outside AWS starting in late 2027, according to the source material.
Capital investment is recorded as assets and generally recognized as expenses over time through depreciation and amortization. Amazon reported that this expense rose 25% to $20.9 billion in the quarter. As new equipment is put into service, depreciation can add to operating costs over multiple years. Amazon has also flagged energy prices and memory-chip supply volatility as risks, but it did not disclose how much of the quarter’s spending went specifically to power.
“The capital spending primarily relates to AWS and AI.”
— Amazon CFO Brian Olsavsky
Cash Returns and Capacity Timing
Amazon has not provided a precise timeline for when its new infrastructure investment will translate into improved free cash flow. The $578 billion AWS order book is a measure of contracted future revenue, but the source material does not give a schedule for when that revenue will be recognized or collected, nor how much investment is needed to fulfill each contract.
It is also unclear how much of the spending increase reflects higher equipment costs, including memory, versus additional capacity, and how power constraints may affect data-center schedules. Amazon has identified supply volatility and energy prices as risks but did not give a spending breakdown for those items. The source report’s estimate of about $33.5 billion in quarterly negative free cash flow is its own arithmetic; the company’s reported figure cited here is the trailing 12-month measure.
The precise causes of the share decline cannot be established from the price move alone. The source material reports that AWS growth was strong while earnings, advertising and the holiday revenue forecast disappointed expectations; it does not quantify how much each factor contributed to the after-hours reaction.
2026 Spending and Holiday Results
Investors will watch whether Amazon delivers on its roughly $220 billion 2026 capital-spending plan and how quickly new AWS capacity begins contributing revenue and cash. The company has also said it expects meaningfully higher spending in 2027, but has not provided a dollar estimate in the source material.
The next near-term test is the holiday quarter. Amazon’s guidance was slightly below analyst expectations, according to the source report, so the coming results will show whether retail and advertising performance catches up with expectations while AWS continues to expand. Updates on capacity availability, chip supply, infrastructure costs and the pace of customer revenue would help clarify how the investment is affecting cash generation.
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 reported. The company described it as the fastest pace since the end of 2021.
Why did Amazon shares fall after AWS growth accelerated?
Shares fell more than 6% in after-hours trading after Amazon reported results. The source material points to the scale of capital spending, negative free cash flow, earnings per share below analysts’ estimate, advertising results that missed expectations and a holiday revenue forecast slightly below expectations. The relative effect of each factor is not known.
What does AWS’s $578 billion order book mean?
It is the value of AWS contracted future revenue, according to CEO Andy Jassy, up from $496 billion three months earlier. It is not the same as cash already received, and the source material does not provide a schedule for when the contracted revenue will be recognized.
How much is Amazon spending on capital investments?
Amazon reported $75.9 billion in cash capital spending in the third quarter. It still expects to spend about $220 billion in 2026 and said spending in 2027 will be meaningfully higher.
What remains uncertain about Amazon’s AI investment?
The timing and amount of cash returns remain unclear. Amazon has not detailed when new capacity will be ready, how much of its spending is specifically for power or memory, or when free cash flow may improve.
