TL;DR
Amazon reported 39% third-quarter AWS revenue growth and a $578 billion contracted order book, while quarterly cash capital spending reached $75.9 billion. Free cash flow over the past 12 months turned negative, and shares fell more than 6% in after-hours trading as investors weighed the spending pace alongside results that missed some expectations.
Amazon said AWS revenue rose 39% to $46.0 billion in the third quarter, its fastest growth rate since the end of 2021, while the company spent $75.9 billion on cash capital projects in the quarter. Its shares fell more than 6% in after-hours trading Thursday as investors weighed the cloud unit’s momentum against the cost of expanding capacity and weaker-than-expected parts of Amazon’s results.
AWS operating income increased 55% to $17.8 billion, according to Amazon’s October 29 results. The company’s CEO, Andy Jassy, said AWS had $578 billion in contracted future revenue, up from $496 billion three months earlier. That figure indicates customers have made substantial commitments, but the revenue is expected to be recognized over time rather than arrive immediately.
Chief Financial Officer Brian Olsavsky said the quarter’s $75.9 billion in cash capital spending primarily related to AWS and artificial intelligence. Jassy said most of Amazon’s roughly $220 billion spending plan for 2026 is directed to AWS, and the company expects to spend “meaningfully more” in 2027. Amazon had raised its 2026 spending outlook from about $200 billion in July, citing higher memory prices, CNBC reported.
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 period, the company generated $168.3 billion in operating cash flow and spent $210.7 billion on capital investments. The source estimates quarterly free cash flow at about negative $33.5 billion, calculated from the reported figures; Amazon’s own headline figure is for the 12-month period.
Other results also weighed on the market response. Amazon reported earnings per share of $1.89, below the $1.96 analysts expected, while advertising revenue missed expectations and its holiday-quarter revenue forecast came in slightly below forecasts, according to CNBC, citing LSEG and StreetAccount data. These results help explain why strong AWS growth did not prevent the share decline.

AWS Growth Requires Heavy Investment
The results highlight a mismatch in timing: Amazon is spending heavily now to build data centers and acquire equipment, while customers’ contracted commitments produce revenue as capacity is delivered and used. The $578 billion AWS order book offers evidence of demand, but it is not the same as cash already received or revenue recognized in the quarter.
For investors, the issue is whether future AWS earnings will justify the cost and whether Amazon can finance its expansion without putting sustained pressure on cash flow. The company’s reported negative $42.4 billion trailing free cash flow makes that trade-off more visible. For cloud customers, capacity availability and the cost of AI computing may matter as much as AWS’s growth rate: the source says large blocks of AI capacity are being reserved well in advance and short-term capacity on older AI chips is selling at a premium.
Amazon’s spending also has implications beyond the cloud unit. The company operates a large retail and advertising business, and the quarter’s weaker-than-expected results in those areas contributed to the mixed picture. The market reaction suggests that investors are considering both the potential returns from AI infrastructure and the cash required to build it, rather than treating demand commitments alone as proof of a payoff.

The Spending Build-Up Behind AWS
AWS growth has accelerated over 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 supplied source material. The latest rate marks a sharp contrast with the slower growth AWS recorded earlier in that period and shows that demand has strengthened while Amazon expands its infrastructure.
The build-out includes data centers, servers and chips. Amazon’s property and equipment rose from $357.0 billion at the end of 2025 to $508.9 billion at the end of September. Jassy said the company was “installing an AI accelerator about every 14 seconds.” Amazon designs its own Trainium AI chips and Graviton processors; the company says commitments for both product lines increased more than 20-fold in a year. Its claim that customers saved more than $2 billion in the quarter by using its chips is a company estimate, not an independently verified figure.
Jassy has also argued that owning or leasing infrastructure for the long term can be more profitable than renting capacity from specialist providers. He said cloud providers that rent from “neoclouds” earn about 35 percentage points less operating margin. That is his competitive argument, rather than an audited comparison. Amazon has also cited memory costs and supply volatility among risks, while announcing a $1 billion “Built Together” program for communities near its U.S. data centers, including energy and water-efficiency upgrades.
“Amazon is “installing an AI accelerator about every 14 seconds.””
— Amazon CEO Andy Jassy
The Timing of Returns Remains Unclear
Amazon has not provided a specific timetable for when the current investment wave will produce enough additional cash flow to offset its costs. The order book reflects contracted future revenue, but the supplied results do not give a schedule for when the $578 billion will be recognized, how much will come from AI services, or what margins those contracts will carry.
The company also did not disclose how much of its capital spending is going to electricity supply, data-center construction, chips or other equipment. Its figures show the overall scale of investment, but do not let investors calculate a precise return for each category. Nor is it clear how long supply constraints and elevated memory prices will affect costs and how much capacity AWS can bring online in response to demand.
The precise quarterly free-cash-flow figure in the source is an author calculation, not a directly quoted Amazon metric. Amazon’s stated 12-month figure is negative $42.4 billion. The company’s future spending and earnings will determine whether that cash-flow measure improves, but the results do not settle that question.
Watch AWS Capacity and Cash Flow
Investors will look to Amazon’s next quarterly results for updates on AWS revenue growth, operating income and capital spending, as well as whether free cash flow continues to weaken or begins to recover. The company’s guidance points to about $220 billion in capital spending during 2026 and a higher amount in 2027, making execution and the pace at which new capacity becomes available central to the outlook.
Customers will also be watching for changes in access to AI computing and the prices of different capacity options. Amazon said it plans to sell its Trainium chips outside AWS beginning in late 2027. That remains a future plan, not a current product launch. Further details on deployment schedules, customer demand and the costs of operating new data centers may clarify how quickly AWS can turn its contracted commitments into recognized sales and cash.
For now, the confirmed picture is mixed: AWS is growing rapidly and its future-revenue commitments have expanded, while the infrastructure build-out has pushed trailing free cash flow into negative territory. The company’s next disclosures will show whether revenue and profits can keep pace with its investment demands.
