Amazon shares fell in after-hours trading after the company paired strong third-quarter growth with a holiday-quarter sales outlook that disappointed parts of Wall Street and a sharp increase in cash spending. The company reported third-quarter net sales of $201.9 billion, up 12% from a year earlier, while Amazon Web Services grew 39.3% to a $184 billion annualized revenue run rate. Operating income reached $28.1 billion and the operating margin rose to a company record 13.9%.
AWS was the strongest part of the quarter
Cloud revenue accelerated to its fastest growth rate in nearly five years. That matters because investors increasingly view AWS as the engine that can justify Amazon’s enormous spending on data centers, chips and artificial intelligence infrastructure.
The cloud unit’s 39.3% growth rate exceeded the pace seen through much of the previous two years and suggested that enterprise demand for AI-related computing capacity remains strong.
The holiday forecast was less convincing
Amazon said fourth-quarter net sales are expected to be between $240 billion and $247 billion. The midpoint is close to analysts’ expectations, but the lower end of the range raised concerns about consumer demand during the critical holiday season.
The company also warned that foreign-exchange movements, energy prices, tariffs, inflation and broader economic conditions could affect results.
Capital spending is the central investor concern
Amazon continues to expect roughly $220 billion of capital expenditure in 2026. Spending has been directed heavily toward data centers, AI hardware, logistics and network expansion.
Reuters reported that trailing 12-month cash burn reached $42.4 billion in the September quarter, highlighting the scale of investment. Investors are asking whether future AI revenue will arrive quickly enough to support those outlays.
Operating margins still improved
Despite the spending pressure, Amazon’s operating margin reached a record 13.9%. That shows the company is generating more profit from its core operations even while investing at an unusually high level.
Cost discipline in retail, higher-margin advertising and AWS growth have helped lift profitability.
Prime Day timing distorted comparisons
Amazon said the timing of Prime Day shifted between years, making the headline sales comparison less straightforward. The company estimated that without the timing shift, third-quarter year-over-year growth would have been roughly four percentage points higher.
This matters because promotional events can move billions of dollars of revenue between quarters.
Advertising remains an important profit driver
Amazon’s advertising business has become one of its most attractive high-margin segments. The company expects advertising growth to accelerate into the high teens in the fourth quarter.
Its ability to monetize shopping data gives Amazon an advantage over many traditional digital advertising platforms.
Consumer spending remains resilient but uneven
The broader U.S. economy grew at a 3.4% annual rate in the third quarter, helped by consumer spending. But high fuel prices and elevated borrowing costs are still affecting household budgets.
Amazon’s cautious guidance suggests management is not assuming that strong macroeconomic growth will translate automatically into an exceptional holiday shopping season.
AI investment is becoming an accounting issue too
Amazon and other technology giants are facing increasing scrutiny over how quickly AI servers and chips may become obsolete. If equipment has to be depreciated over shorter periods, reported profits could come under pressure even if revenue remains strong.
The debate reinforces why free cash flow and return on invested capital are becoming as important as revenue growth.
Rural delivery expansion continues
Amazon is also spending to improve delivery speed and reach in smaller communities. Faster logistics can increase customer loyalty, but it requires warehouses, transportation capacity and technology investment.
The company is balancing that retail expansion with its much larger AI infrastructure program.
The next quarter will test the investment thesis
Amazon’s third quarter showed that AWS demand remains powerful and operating profitability is improving. The unresolved question is whether the company’s extraordinary capital spending will generate returns fast enough to satisfy investors.
The fourth quarter will provide the next major test, particularly if holiday demand comes in near the lower end of guidance while AI infrastructure spending remains elevated.

Cash flow will determine how patient investors remain
Amazon can continue financing extraordinary infrastructure spending because its operating businesses generate enormous cash flow, but the balance is becoming more important. Investors are increasingly separating accounting profit from cash generation and asking how quickly new data centers begin producing returns. A strong AWS growth rate helps the argument, but capital intensity means revenue growth alone is no longer enough.
The company also faces a timing problem: infrastructure must often be built before customers commit to long-term usage. That creates periods in which spending rises faster than revenue. If AI demand remains strong, the strategy could create a powerful capacity advantage. If demand slows, underused assets would become a drag on returns.
