Amazon shares (NASDAQ: AMZN) came under heavy pressure after the company reported its third-quarter 2026 financial results on October 29. The sell-off followed a rare double miss, with Amazon reporting revenue and earnings per share below Wall Street expectations. Investors also reacted to the company’s enormous artificial intelligence infrastructure spending and its warning that capital expenditure will remain elevated.
The decline came despite strong performance from Amazon Web Services (AWS), whose revenue grew 39.3% year over year, its fastest growth rate in nearly five years. The bigger concern was whether Amazon can turn its growing AI and cloud business into sufficient cash flow to justify its rapidly increasing investment. While some market reports cited declines exceeding 12% in subsequent trading snapshots, Reuters initially reported a fall of as much as 7% in after-hours trading following the announcement.
Key Takeaways
- Amazon reported third-quarter revenue of $201.9 billion, up 12% year over year but slightly below analyst expectations.
- Earnings per share came in at $1.89, missing the expected $1.96.
- AWS revenue surged 39.3% to $46 billion, its fastest growth in nearly five years.
- Amazon’s trailing 12-month free cash flow fell to a negative $42.4 billion.
- The company expects approximately $220 billion in capital expenditure for 2026.
- CEO Andy Jassy indicated that spending will be meaningfully higher in 2027.
- Fourth-quarter revenue guidance came in below the midpoint of analyst expectations.
Why Did Amazon Stock Fall After Q3 Earnings?
The biggest concern was the combination of disappointing financial results and rising investment requirements.
Amazon’s third-quarter revenue reached $201.9 billion, representing 12% year-over-year growth. However, analysts had expected approximately $202.3 billion.
The company also reported diluted earnings of $1.89 per share, below the analyst estimate of approximately $1.96.
These misses were relatively small in percentage terms, but investors were already concerned about the enormous amount Amazon is spending to expand its AI infrastructure.
The company’s capital expenditure is increasing rapidly as it builds data centers, purchases computing equipment and expands the infrastructure required to support cloud and AI workloads.
Investors want evidence that these investments will generate enough future revenue and profit to justify the costs.
Amazon Q3 2026 Earnings: Key Financial Numbers
Amazon’s financial results showed strong operating performance in several areas, even as net income declined slightly.
| Financial metric | Q3 2026 result | Year-over-year change |
|---|---|---|
| Net sales | $201.9 billion | +12% |
| Operating income | $28.1 billion | +61% |
| Net income | $20.7 billion | -2% |
| Diluted EPS | $1.89 | -3% |
| AWS revenue | $46.0 billion | +39.3% |
| AWS operating income | $17.8 billion | +55% |
| North America revenue | $112.9 billion | +6% |
| International revenue | $43.1 billion | +5% |
Source: Amazon’s official third-quarter 2026 earnings release. Figures are rounded.
One important detail is that Amazon’s operating income increased substantially, reaching a record operating margin of 13.9%.
However, net income declined from $21.2 billion to $20.7 billion. Amazon explained that the comparison was affected by $9.5 billion in pre-tax gains from its investments in Anthropic during the third quarter of 2025.
This means the headline earnings decline does not necessarily indicate that Amazon’s core operations deteriorated by the same amount.
AWS Grows 39% as AI Demand Accelerates
The strongest part of Amazon’s earnings report was AWS.
Amazon Web Services generated $46 billion in revenue during the third quarter, up 39.3% from the previous year. The division reached an annualized revenue run rate of approximately $184 billion.
AWS also generated $17.8 billion in operating income, compared with $11.4 billion in the same quarter last year.
The growth reflects increasing demand for cloud computing, data center capacity and AI-related services.
Companies developing and deploying AI systems require substantial computing infrastructure. AWS provides cloud services that allow businesses to access computing power, storage and AI tools without building all the infrastructure themselves.
Amazon CEO Andy Jassy said the company’s infrastructure investments were working and pointed to projected AWS revenue growth rates of more than 40% in both 2027 and 2028.
This is an important signal for Amazon’s long-term strategy. The company believes demand for AI computing will continue expanding, creating opportunities for AWS to grow.
However, the market’s immediate concern is whether the financial returns will arrive quickly enough to offset the investment.
Amazon’s $220 Billion AI Spending Plan Raises Concerns
Amazon’s capital expenditure is one of the biggest reasons investors are questioning the company’s financial outlook.
The company expects capital expenditure of approximately $220 billion in 2026. CEO Andy Jassy also indicated that spending would be meaningfully higher in 2027.
During the third quarter alone, Amazon spent approximately $77.3 billion on capital expenditure, according to Reuters.
Much of this investment is directed toward AI infrastructure, including data centers, servers, networking equipment and other computing resources.
The strategy is designed to ensure AWS has enough capacity to serve customers as demand for AI computing increases.
But building this infrastructure requires significant upfront spending. The returns may take years to fully materialize.
Investors are therefore trying to determine whether Amazon is investing ahead of a major growth opportunity or taking on too much financial risk before the returns become visible.
Free Cash Flow Turns Deeply Negative
The most striking financial figure in Amazon’s earnings report was its free cash flow.
For the trailing 12 months, Amazon reported a free cash flow outflow of $42.4 billion, compared with a positive inflow of $14.8 billion in the same period a year earlier.
That represents a substantial deterioration.
The company attributed the decline primarily to a $94.8 billion year-over-year increase in purchases of property and equipment, net of sales and incentives. Amazon said these investments primarily reflect spending on artificial intelligence.
It is important to distinguish between free cash flow and profitability.
Amazon is still generating substantial operating cash flow. Its trailing 12-month operating cash flow increased 29% to $168.3 billion.
However, after deducting the cost of purchasing property and equipment, free cash flow turned negative.
| Cash flow metric | Latest figure |
|---|---|
| Operating cash flow, trailing 12 months | $168.3 billion |
| Free cash flow, trailing 12 months | -$42.4 billion |
| Previous-year free cash flow | +$14.8 billion |
| 2026 expected capital expenditure | Approximately $220 billion |
Negative free cash flow does not automatically mean a company is in financial trouble. It can also reflect aggressive investment in future growth.
The important question is whether Amazon’s spending eventually produces enough additional revenue and operating profit to improve cash generation.
Advertising Business Also Disappoints
Amazon’s advertising business provided another reason for investor concern.
Advertising revenue reached approximately $19.6 billion in the third quarter, growing 11% year over year. However, the result was below analyst expectations of approximately $20.8 billion.
This was notable because Amazon’s advertising business has become an important source of higher-margin revenue.
The company said advertising growth was affected by timing factors, including the shift in Prime Day timing between the second and third quarters.
Amazon expects advertising revenue growth to accelerate into the high teens during the fourth quarter.
Investors will watch whether that improvement materializes, particularly during the holiday shopping season.
Amazon’s Q4 Guidance Adds to Investor Concerns
Amazon expects fourth-quarter 2026 net sales between $240 billion and $247 billion.
The midpoint of that range is $243.5 billion, slightly below the analyst consensus of approximately $244.5 billion cited by Reuters.
The company expects operating income between $28.5 billion and $33.5 billion, compared with $25 billion in the fourth quarter of 2025.
Although the operating income range indicates potential year-over-year growth, investors were concerned that revenue guidance did not provide the stronger outlook they wanted.
The fourth quarter is especially important because it includes major holiday shopping events and seasonal consumer spending.
Amazon’s performance during this period will help investors evaluate whether its retail business can maintain growth while the company continues expanding its cloud and AI operations.
The Bigger Picture
Amazon’s latest earnings report reveals a growing divide between its operating performance and its cash generation. AWS is expanding rapidly, operating income has reached a record level, and demand for AI infrastructure remains strong. However, the cost of building that infrastructure is placing significant pressure on free cash flow.
The market is not necessarily questioning whether AI demand exists. Instead, investors are asking how much Amazon must spend to capture that demand and how long it will take for those investments to generate attractive returns. The company’s ability to balance infrastructure expansion with profitability will be central to its valuation.
Looking Ahead
Investors will closely monitor AWS revenue growth, capital expenditure, advertising performance and free cash flow over the coming quarters. Amazon’s forecast for higher spending in 2027 means the market will likely demand clearer evidence that AI investments are producing measurable financial returns. The holiday quarter will also provide an important test of consumer demand and the company’s retail performance.
Amazon remains a major player in cloud computing and AI infrastructure, but strong long-term opportunities do not eliminate short-term financial risks. The key question is whether AWS growth can continue accelerating while Amazon gradually improves cash generation. Until investors see that balance, heavy spending may remain a source of volatility for AMZN shares.
