Amazon Q3 2026: AWS Growth and Record Margin, Yet Shares Fall
Amazon delivered its highest operating margin ever and the fastest AWS growth in nearly five years. Investors still sold the stock, focusing on a slight miss and the soaring cost of building for AI.
Highlights
- Amazon Q3 2026 net sales rose 12% to $201.9 billion, with operating income of $28.1 billion and a record 13.9% operating margin
- AWS sales grew 39% to $46.0 billion — a $184 billion annualised run rate and the fastest growth in nearly five years
- Results slightly missed consensus on revenue, EPS and advertising, and shares fell about 7% in extended trading
- Q3 capex reached $77.3 billion, with full-year 2026 cash capex guidance of about $220 billion, mainly for AI
- Q4 guidance calls for net sales of $240–247 billion and operating income of $28.5–33.5 billion
The headline numbers
Amazon announced its Q3 2026 results, for the quarter ended 30 September 2026, on Thursday 29 October 2026 Amazon. Net sales rose 12% to $201.9 billion ($201.94bn), compared with $180.2bn in Q3 2025, and were up 13% excluding foreign exchange Amazon.
Operating income rose to $28.1 billion versus $17.4 billion a year earlier, giving an operating margin of 13.9% — the highest ever Amazon.
Net income fell to $20.7 billion, or $1.89 in diluted earnings per share, versus $21.2bn and $1.95 a year earlier, mainly because Q3 2025 included $9.5 billion of pre-tax gains from the Anthropic investment Amazon. That comparison matters: operating income rose sharply, so the net income decline reflects a one-off gain in the prior year, not weaker operations.
Why shares fell despite the record margin
Shares fell about 7% in extended trading, with CNBC TV18 putting the fall at 7.3% to $225.99 in its snapshot — early snapshots differed, so about 7% is the fairest description CNBC TV18.
The immediate trigger was a slight consensus miss. Revenue of $201.94bn came in versus $202.31bn expected, EPS of $1.89 versus $1.96 expected, and advertising of $19.64bn versus $20.82bn expected CNBC TV18. None is large, but together they set the tone on a night when, as covered in our report on earnings night: Microsoft and Alphabet results, investors were already judging big tech on whether AI spending pays back. The second factor was spending itself, covered below.
AWS is accelerating again
AWS sales grew 39% to $46.0 billion — a $184 billion annualised run rate and the fastest growth in nearly five years — while AWS operating income rose to $17.8bn versus $11.4bn a year earlier Amazon.
President and CEO Andy Jassy framed that growth as the payoff from earlier investment:
“Our AWS investment in functionality and infrastructure is working, with over 39% year-over-year revenue growth in Q3 ($184 billion revenue run rate) and projected revenue growth rates of over 40% both in 2027 and in 2028,” — Andy Jassy, President and CEO Amazon
Jassy is not presenting 39% as a one-quarter spike, but as a level he expects to build on in 2027 and 2028. He also set out the scale of his ambition:
“There has never been a trillion dollar revenue business, and we may have two of them in the next 5-10 years.” — Andy Jassy, President and CEO Amazon
The brief does not name which two businesses he means, and this article will not guess. The point is that leadership is asking investors to judge today’s spending against very large long-term opportunities, not just next quarter’s cash flow.
The rest of the business
North America sales rose 6% to $112.9bn, with operating income of $8.7bn versus $4.8bn a year earlier, while International sales rose 5% to $43.1bn Amazon.
That pattern explains the whole result: retail growing in single digits and contributing more profit, while the acceleration story belongs to the cloud. It also explains why the advertising miss drew attention — advertising is a high-profile growth line outside AWS, and $19.64bn versus $20.82bn expected softens the broader narrative CNBC TV18.
Cash flow and the cost of AI
Careful reading is essential here. Trailing-12-month operating cash flow rose 29% to $168.3bn, but trailing free cash flow was an outflow of $42.4 billion, versus an inflow of $14.8bn a year earlier, driven by a $94.8bn rise in net property and equipment purchases, mainly for AI Amazon. The -$42.4bn figure is a trailing-12-month figure, not a single quarter.
Q3 capex was $77.3 billion versus around $58.7bn expected, and full-year 2026 cash capex guidance is about $220 billion CNBC TV18. Spending well above expectations, at that full-year scale, is what investors weighed against the record margin.
Guidance for Q4
For the fourth quarter, Amazon guided to net sales of $240–247 billion, up 12% to 16%, and operating income of $28.5–33.5bn, versus $25.0bn in Q4 2025 Amazon. That is not a slowdown warning: the sales range would match or exceed the Q3 growth rate, and both ends of the operating income range sit above the prior-year quarter. The tension is between strong operating guidance and the size of investment needed to sustain the AWS growth Jassy projects.
What this means
Amazon’s report contains two stories that are both true. The operating story is excellent: sales up 12% to $201.9 billion, operating income up to $28.1 billion, a record 13.9% margin, and AWS accelerating to 39% on a $184 billion run rate. The investment story is demanding: $77.3 billion of capex in one quarter, about $220 billion guided for the full year, and trailing free cash flow swinging to a $42.4 billion outflow.
The market, on the night, priced the second story and the slight consensus miss, sending shares down about 7%. Whether that looks right in hindsight depends on Jassy’s central claim — that today’s infrastructure investment produces over 40% projected AWS growth in 2027 and 2028. Amazon has given investors the numbers to test that claim against.
