TL;DR
Amazon reported that AWS revenue grew 39% in the third quarter, its fastest pace since late 2021, while the cloud unit’s operating income rose 55%. At the same time, Amazon spent $75.9 billion on capital investments in the quarter and reported negative trailing-12-month free cash flow of $42.4 billion; its shares fell more than 6% in after-hours trading.
Amazon reported 39% AWS revenue growth in the third quarter, the cloud unit’s fastest pace since late 2021, even as the company spent $75.9 billion on cash capital investments and its trailing-12-month free cash flow fell to negative $42.4 billion. Amazon shares dropped more than 6% in after-hours trading following the October 29 results, as investors weighed the accelerating cloud business against the cost of its AI and data-center build-out and weaker-than-expected results in other areas.
AWS revenue reached $46.0 billion for July through September, up 39% year over year. It was the sixth consecutive quarter in which AWS growth accelerated, according to the results, with reported rates rising from 17% in the second quarter of 2025 to 20%, 24%, 28%, 37% and 39%. AWS operating income increased 55% to $17.8 billion.
Amazon Chief Executive Andy Jassy said AWS had $578 billion in contracted future revenue, up from $496 billion three months earlier. That order book points to substantial customer commitments, but the contracted revenue is expected to be recognized over time; it does not remove the near-term cost of building and equipping capacity.
Chief Financial Officer Brian Olsavsky said the quarter’s $75.9 billion in cash capital spending primarily related to AWS and artificial intelligence. Amazon expects to spend about $220 billion in 2026 and said spending would be “meaningfully more” in 2027. Jassy said most of the 2026 investment is intended for AWS.
Amazon’s trailing-12-month free cash flow was negative $42.4 billion, compared with positive $14.8 billion a year earlier. The company generated $168.3 billion in operating cash over that period, while capital spending was $210.7 billion. Amazon’s quarterly earnings per share of $1.89 fell short of the $1.96 analysts expected, and the source material reports that advertising revenue and the company’s holiday-quarter revenue outlook also disappointed expectations.

The Cost of Building AWS Capacity
The results show the tension at the center of Amazon’s AI strategy: customer demand and AWS sales are rising, but the infrastructure needed to meet that demand requires very large investments before all related revenue is collected. Data centers, servers, chips, power and other equipment are paid for upfront or over contracts, while customers use capacity and pay over time.
For investors, the question is not simply whether AWS is growing. It is whether the new capacity will generate enough revenue and profit to justify its cost, and how long Amazon can sustain investment at this level. The company reported stronger AWS operating income, but its overall cash flow figures show that capital spending is currently outpacing the cash Amazon generates from operations.
For cloud customers, the build-out may determine how quickly providers can supply AI computing capacity and what that capacity costs. The source report says large blocks are being reserved well in advance and short-term access to older AI chips is selling at a premium. Those details point to potential supply constraints, though Amazon’s results do not establish how every customer or service will be affected.

From Data Centers to Trainium Chips
Amazon’s investment is not limited to buildings. The company designs Trainium AI accelerators and Graviton processors, and Jassy said commitments for the two chip lines had increased more than 20-fold in a year. Amazon said customers saved more than $2 billion during the quarter by using its own chips; that figure is the company’s estimate, not an independently verified measure.
Amazon’s property and equipment increased 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. Depreciation and amortization, which spreads the cost of assets over their useful lives, rose 25% to $20.9 billion in the quarter. That expense can continue after the equipment has been purchased and put into service.
The investment plan has risen during the year: Amazon had indicated about $200 billion in planned 2026 spending in February, then raised that figure in July, citing higher memory prices. Jassy also said the majority of current AWS capacity is owned or secured through long-term leases. 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.
How Quickly Spending Pays Back
Amazon has not provided a precise timetable for when its current data-center and chip investments will produce returns sufficient to reverse the free-cash-flow decline. The $578 billion AWS order book represents contracted future revenue, but the source material does not specify how much will be recognized in each period, what margins it will carry, or how much additional investment will be required to deliver it.
It is also unclear how much of Amazon’s capital spending is attributable to individual cost categories such as electricity, memory, buildings and servers. Jassy cited higher component costs, including memory, while Amazon’s guidance identified energy prices and supply volatility as risks. The reported fall in shares followed the earnings release, but the source material does not establish a single cause for the market reaction; it also points to earnings per share, advertising and holiday-quarter guidance falling short of expectations.
Watching Spending and AWS Demand
Investors and cloud customers will look to Amazon’s next earnings update for changes in AWS growth, operating income, capital spending guidance and free cash flow. The near-term test is whether Amazon can keep adding capacity while converting its reported customer commitments into delivered services and recognized revenue.
Amazon’s stated plans point to continued heavy investment: about $220 billion in capital spending for 2026 and meaningfully more in 2027. The company has also said it plans to sell its Trainium chips outside AWS from late 2027. The timing, scale and commercial impact of that wider availability remain ahead, while the results released this quarter establish the current picture: strong AWS growth alongside unusually high spending and negative free cash flow.
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 described it as the unit’s fastest growth since late 2021.
Why did Amazon shares fall after the results?
Amazon shares fell more than 6% in after-hours trading. The source report points to the scale of capital spending and negative free cash flow, as well as earnings per share, advertising results and the holiday-quarter revenue outlook missing expectations. The release does not identify one definitive cause for the share move.
What does Amazon’s $578 billion AWS order book mean?
Jassy said AWS had $578 billion in contracted future revenue, up from $496 billion three months earlier. It indicates customer commitments for future services, but does not mean all of that revenue will arrive immediately or reveal the timing and profitability of each contract.
How much is Amazon planning to spend?
Amazon expects about $220 billion in capital spending in 2026 and said spending in 2027 would be meaningfully higher. The company said most of the 2026 plan is for AWS, with the quarter’s spending primarily related to AWS and AI.
What remains uncertain about the AI investment?
The results do not establish when the spending will generate returns sufficient to lift free cash flow, how much future investment will be needed, or how quickly AWS can turn its contracted commitments into delivered capacity and recognized revenue.
