TL;DR
AWS revenue rose 39% to $46 billion in the third quarter, while Amazon spent $75.9 billion on capital investments, primarily for AWS and AI. Trailing 12-month free cash flow fell to negative $42.4 billion as the company expanded capacity ahead of contracted demand. Amazon shares dropped more than 6% in after-hours trading after results also missed some analyst expectations.
Amazon reported that AWS revenue rose 39% to $46.0 billion in the third quarter, its fastest growth since late 2021, while the company spent $75.9 billion on capital investments, primarily for cloud and artificial-intelligence infrastructure. Trailing 12-month free cash flow was negative $42.4 billion, and Amazon shares fell more than 6% in after-hours trading Thursday as investors weighed the cost of building capacity against the timing of future returns.
AWS operating income climbed 55% to $17.8 billion, according to Amazon’s October 29 results. Revenue growth has accelerated for six consecutive quarters, from 17% to 39% since the second quarter of 2025, excluding currency effects. The company also reported a $578 billion AWS order book, up from $496 billion three months earlier. Chief Executive Andy Jassy said the increase reflected contracted future revenue; it does not mean all of that revenue will be received immediately.
Amazon’s cash capital spending of $75.9 billion in the quarter was nearly twice the cash generated by its business over the same three-month period, according to the source report’s calculation. The company’s trailing 12-month operating cash flow was $168.3 billion, while capital spending was $210.7 billion. That left free cash flow at negative $42.4 billion, compared with positive $14.8 billion a year earlier. The source estimates quarterly free cash flow at about negative $33.5 billion; that figure is its calculation, not a separately stated Amazon metric.
Amazon still expects about $220 billion in capital spending in 2026 and said spending in 2027 would be “meaningfully more.” Chief Financial Officer Brian Olsavsky said the quarter’s capital spending “primarily relates to AWS and AI.” Jassy said most of the planned 2026 spending was for AWS. 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 over nine months.

The Cost of Building AI Capacity
The results show a growing gap between cloud demand and cash timing. Amazon is paying for data centers, servers, chips and related equipment before all the resulting capacity can generate revenue. AWS’s order book indicates customers have contracted for substantial future services, but those commitments are delivered and paid for over time. The near-term investment burden is therefore landing on Amazon’s cash flow now, while the earnings from new capacity are expected across later periods.
The spending also matters to customers and investors for different reasons. For businesses that rent cloud computing, adding capacity can support access to AI services and computing resources; however, the source material does not establish what this investment will mean for customer prices or availability. For investors, the key question is how quickly new infrastructure can be used profitably. Amazon’s shares fell after the results despite AWS’s strong growth, amid the cash-flow decline and other results that fell short of analyst expectations.
Those other results included earnings per share of $1.89, below the $1.96 analysts expected, and advertising revenue that missed expectations, according to the source’s reporting of analyst data. Amazon’s holiday-quarter revenue forecast also came in slightly below expectations. That means the market reaction cannot be attributed to capital spending alone; the source describes both the investment burden and weaker-than-hoped retail and advertising indicators as factors.

How the Investment Is Being Funded
Amazon says the build-out includes data centers and computing equipment, along with its own chips. The company designs Trainium AI accelerators and Graviton processors. Jassy said commitments for both chip lines rose more than 20-fold in a year, and that the chip business was growing at triple-digit rates. Amazon also said customers saved more than $2 billion in the quarter by using its chips; that is the company’s estimate, not an independently verified figure in the supplied material.
Jassy said Amazon is installing an AI accelerator about every 14 seconds. Depreciation and amortization, which spreads the cost of equipment and other assets over their useful lives, rose 25% to $20.9 billion in the quarter. That expense reflects a longer-term cost of the build-out: equipment bought now affects results over time, even after the cash has already been spent.
Amazon has raised its 2026 capital-spending plan from about $200 billion to roughly $220 billion, citing higher memory prices when it increased the outlook in July, according to CNBC as cited by the source. Jassy also pointed to elevated component costs, including memory. Amazon’s guidance lists energy prices and supply volatility, including for memory chips, as risks. The company has announced a separate $1 billion “Built Together” commitment for communities near its U.S. data centers, including energy and water-efficiency upgrades; the source does not say how much of the overall capital budget is allocated to power.
When Spending Becomes Revenue
The results do not specify when the new capacity will be fully deployed or how quickly it will generate cash and earnings. The $578 billion order book represents contracted future revenue, but the source does not provide a schedule for when those contracts will be fulfilled, how much capacity each requires, or the margins they will produce.
It is also unclear how the scale of spending will change after 2027 or what portion of future investment will go to data centers, chips, energy and other equipment. Amazon has cited higher memory costs and supply volatility, but the supplied material does not quantify their effect on project costs. Jassy’s comparison of the margins from owned or long-term leased capacity with those of cloud providers that rent from specialist suppliers is a competitive argument made by the CEO, not an audited figure.
The source reports a $65.6 billion-to-$173.1 billion rise in long-term debt over nine months, but does not establish that the increase directly financed the quarter’s capital spending. It also does not give a breakdown of how the investment was funded across operating cash, debt and other sources. The precise quarterly free-cash-flow estimate is the source writer’s calculation; Amazon’s reported comparison is for the trailing 12 months.
Watch Spending and Capacity Delivery
The next indicators are Amazon’s capital-spending updates, AWS revenue and operating income, and changes in free cash flow. Those figures will help show whether the company’s new data-center and chip capacity is entering service quickly enough to support the demand reflected in the order book. Amazon has indicated it expects about $220 billion of capital spending in 2026 and meaningfully more in 2027, so investors will be watching for any revision to that outlook and for evidence of the associated returns.
Capacity availability is another near-term issue for cloud customers. The source says large blocks of AI capacity are being reserved well in advance and that short-term access to older AI chips is selling at a premium, but it does not provide detailed market-wide pricing or availability data. Amazon has also said it plans to sell Trainium chips outside AWS beginning in late 2027. That is a future plan, not a current product launch.
Amazon’s next earnings updates should clarify spending, demand and deployment, though the supplied material does not give a date for the next report. Until then, the confirmed results show strong AWS growth alongside a large infrastructure bill; how quickly the investment converts into sustainable cash generation remains open.
Key Questions
Why is Amazon spending so much while AWS is growing?
Amazon says the $75.9 billion in quarterly cash capital spending primarily related to AWS and AI. The investment pays for infrastructure such as data centers, servers and chips that support cloud and AI services. Amazon is spending before all the new capacity has been deployed and paid for by customers.
What does AWS’s $578 billion order book mean?
It is the value of contracted future AWS revenue reported by Andy Jassy, up from $496 billion three months earlier. It does not mean Amazon receives that money immediately; revenue is expected to come as contracted services are delivered over time.
How much did Amazon’s free cash flow change?
Amazon’s trailing 12-month free cash flow was negative $42.4 billion, compared with positive $14.8 billion a year earlier. The source separately estimates the quarter’s free cash flow at about negative $33.5 billion, based on its own calculation.
No. AWS grew 39%, but Amazon shares fell more than 6% in after-hours trading Thursday. The source links the reaction to heavy investment and negative free cash flow, as well as earnings per share, advertising results and a holiday-quarter revenue forecast that missed or fell slightly below analyst expectations.
What will show whether the spending is paying off?
Future AWS revenue and operating income, free cash flow, and updates on capital spending will show how the build-out is progressing. The source does not specify when the new infrastructure will be fully deployed or when its cash returns will match the investment.
