TL;DR
Amazon said AWS revenue rose 39% to $46 billion in the third quarter, its fastest growth rate since late 2021, while its contracted future revenue reached $578 billion. The company spent $75.9 billion on capital investments during the quarter and reported trailing 12-month free cash flow of minus $42.4 billion; its shares fell more than 6% in after-hours trading.
Amazon said AWS revenue rose 39% to $46.0 billion in the third quarter, its fastest growth since the end of 2021, as the cloud unit’s operating income increased 55% to $17.8 billion. But the company also reported $75.9 billion in cash capital spending for the quarter and trailing 12-month free cash flow of minus $42.4 billion, a widening cash gap that helped send Amazon shares down more than 6% in after-hours trading.
The spending is tied mainly to data centers, AI computing capacity and equipment. Chief Financial Officer Brian Olsavsky said on Amazon’s earnings call that the quarter’s capital spending “primarily relates to AWS and AI.” Chief Executive Andy 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 planned about $200 billion for 2026 earlier in the year and raised its forecast in July, citing higher memory prices.
AWS’s contracted future revenue, which Amazon calls its order book, reached $578 billion, up from $496 billion three months earlier, Jassy said. The $82 billion increase suggests substantial customer commitments, but it is not revenue already collected: contracts are fulfilled over time as capacity is delivered and used. Amazon said demand for AI capacity is strong, with some large blocks booked in advance and short-term access to older AI chips selling at a premium.
The cloud results were not the only numbers investors weighed. 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 the source material’s account of analyst estimates and market data. AWS growth accelerated for a sixth consecutive quarter, from 17% in the second quarter of 2025 to 39% in the latest quarter, excluding currency effects.

The Cost of Building AI Capacity
The results show the tension facing Amazon as it expands the infrastructure behind cloud computing and AI: customer commitments and AWS sales are growing, but the construction and equipment costs arrive before all of that contracted business becomes cash revenue. Amazon’s trailing 12-month operating cash flow was $168.3 billion, up 29%, while capital spending over that period rose 82% to $210.7 billion. That gap left free cash flow at minus $42.4 billion, compared with positive $14.8 billion a year earlier.
The investment could support future AWS sales and give Amazon more control over its computing supply. It also puts pressure on cash generation now, while equipment costs can continue affecting earnings over several years through depreciation. For investors, the question is not simply whether demand exists, but how quickly Amazon can turn its build-out into revenue and returns. The share-price decline followed both the spending figures and weaker-than-expected results or guidance elsewhere in the business; the available information does not establish a single cause for the market move.
For businesses that rent cloud services, available capacity and pricing matter directly to their ability to run AI systems and other workloads. Amazon says demand is high and has pointed to constraints involving components such as memory. The company’s own claims about savings from its chips and the economics of owning infrastructure should be treated as company statements, not independent measurements.

AWS Growth Meets a Larger Build-Out
AWS revenue growth has accelerated in each of the six quarters cited by Amazon, rising from 17% to 39% between the second quarter of 2025 and the third quarter of 2026, excluding currency effects. The latest quarter’s operating income of $17.8 billion shows that AWS remains a substantial source of earnings even as Amazon commits large sums to expand it.
The cash investment is also visible on Amazon’s balance sheet. 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. Long-term debt rose from $65.6 billion to $173.1 billion over the same period. Depreciation and amortization increased 25% to $20.9 billion in the quarter, reflecting the accounting cost of assets being spread across their useful lives.
Amazon is building its own chips as well as data centers. Jassy said revenue commitments for its Trainium AI chip and Graviton processor increased more than 20-fold in a year, and said Trainium is used for most workloads on Bedrock, AWS’s service for running AI models. Amazon also said customers saved more than $2 billion in the quarter by using its chips. Those figures are the company’s claims. Amazon plans to sell Trainium chips outside AWS beginning in late 2027, according to the source material.
““Meaningfully more””
— Andy Jassy, Amazon chief executive
Returns and Capacity Remain Unclear
Amazon has not provided a detailed public breakdown of the $75.9 billion quarterly outlay across data centers, chips, networking equipment, energy and other items. It also has not specified how much of its investment is allocated to power infrastructure. The company cited higher memory costs and supply volatility as risks, but the source material does not quantify their effect on the full spending plan.
The $578 billion order book is a measure of contracted future revenue, not a guarantee that all of it will be recognized on a particular schedule or at a particular margin. Amazon has not said how quickly those commitments will convert into delivered capacity, sales and cash. The timing and returns on the investment remain uncertain, as does how long free cash flow will stay negative.
The reported share-price move followed several results and forecasts, including the earnings-per-share miss, the advertising shortfall and the holiday-quarter outlook. The information available does not isolate how much each factor contributed to the decline. Amazon’s assertions about chip savings and the margins available from owned versus rented capacity have not been independently verified in the supplied material.
Spending Plans and Holiday Results
Investors will watch for updates on whether AWS can keep converting its contracted demand into revenue as new data-center and chip capacity comes online. Amazon’s stated outlook is for about $220 billion of capital spending in 2026 and “meaningfully more” in 2027, with most of the current-year plan directed to AWS, according to Jassy. Future results will show whether cash flow begins to recover as the new capacity is used.
The next near-term test is Amazon’s holiday quarter. Its revenue forecast came in slightly below expectations, according to the source material, while the business enters a period that is important for retail sales and advertising. Amazon has not given a specific timetable for free cash flow to turn positive or for AWS demand to ease. Its plans to sell Trainium outside AWS are set for late 2027, so that expansion is not an immediate source of revenue.
Key Questions
How fast did AWS grow in the third quarter?
AWS revenue increased 39% to $46.0 billion in the July-to-September quarter, Amazon reported. The company described this as its fastest growth since the end of 2021.
Why did Amazon shares fall after the results?
Shares fell more than 6% in after-hours trading. The report included $75.9 billion in quarterly cash capital spending, negative trailing 12-month free cash flow, earnings per share below analyst expectations, an advertising miss and a holiday-quarter revenue forecast slightly below expectations. The available information does not identify one cause for the decline.
What does Amazon’s $578 billion AWS order book mean?
It is the value of AWS’s contracted future revenue, which Jassy said was up from $496 billion three months earlier. It is not cash already received, and the timing of when those commitments will become revenue depends on service delivery and customer use.
How much does Amazon plan to spend on capital investments?
Amazon expects about $220 billion in capital spending during 2026 and said it expects to spend “meaningfully more” in 2027. Jassy said most of the 2026 plan is for AWS.
