Amazon reported 39% year-over-year growth in AWS sales for the third quarter of 2026, but its free cash flow for the trailing twelve months turned negative. The tension is central to the investment question: customers are buying more cloud services while Amazon is spending heavily to build the capacity that supports them.
In its October 29 results, Amazon reported $201.9 billion in quarterly net sales and $46.0 billion in AWS sales. All amounts are U.S. dollars. The company reported free cash outflow of $42.4 billion over the trailing twelve months, not the third quarter alone.
Revenue, profit and cash answer different questions
Revenue measures sales recognized during a period. Operating income subtracts expenses under accounting rules, including depreciation, but does not simply equal the cash spent on new equipment in that same period. Free cash flow starts from cash generated by operations and deducts specified investment spending.
Amazon reported quarterly operating income of $28.1 billion, compared with $17.4 billion a year earlier. Meanwhile, it attributed the deterioration in twelve-month free cash flow primarily to higher purchases of property and equipment, largely reflecting AI investment. A profitable quarter and a negative twelve-month free-cash-flow figure are therefore not contradictory.
Time periods matter. Comparing a quarterly operating-income number directly with a twelve-month cash-flow number without labeling them would exaggerate what the comparison can tell us. Investors can review the company’s cash-flow statement and definitions to understand the calculation.
Why does AWS growth require spending?
Cloud customers rent computing services rather than necessarily building all infrastructure themselves. Meeting rising demand requires data centers, networking, power and chips. A provider may invest before the related revenue arrives, and the assets may produce income over years.
The economic outcome depends on utilization, pricing, financing and the useful life of the equipment. If demand remains strong and capacity earns an attractive return, the spending may support future cash generation. If demand grows more slowly or equipment becomes obsolete sooner than expected, returns could disappoint. Neither scenario is established by a single quarter.
Retail sales have a timing wrinkle
Amazon said the timing of Prime Day shifted into the second quarter for most large countries in 2026, whereas it occurred entirely in the third quarter of 2025. The company estimated that third-quarter year-over-year growth would have been approximately four percentage points higher without that shift. That is a company estimate, not a separate audited sales figure.
Reported net income declined to $20.7 billion from $21.2 billion. Amazon said the comparison was affected primarily by a prior-year gain associated with its Anthropic investment. That makes it useful to compare operating results as well as the bottom line.
What should investors watch?
Management forecast fourth-quarter sales of $240 billion to $247 billion. Guidance reflects assumptions and can change. AP reported an after-hours share decline as investors evaluated the outlook and spending; such trading is distinct from the regular-session close and can change.
For a broader comparison, our Alphabet analysis looks at a similar capacity question. Similar headlines do not imply identical businesses or valuations. The relevant test is whether future cash returns justify today’s investment.
