Amazon’s operating margin reached 13.9% in the third quarter, its highest ever, as AWS revenue growth accelerated to 39% year-over-year, the fastest pace in nearly five years. Operating income nearly doubled to $28.1 billion from $17.4 billion in the same quarter last year, driven by margin expansion across all three business segments and a sharp deceleration in retail growth that masks underlying operational improvement.
Total net sales rose 12% to $201.9 billion, or 13% excluding a $0.9 billion foreign exchange headwind. The company noted that Prime Day timing shifted to Q2 this year from Q3 last year, which suppressed the reported quarter by approximately 400 basis points of growth. North America segment sales increased 6% to $112.9 billion, while International rose 5% to $43.1 billion (8% excluding currency effects). AWS segment sales reached $46.0 billion, putting the business on a $184 billion annualized revenue run rate.
Operating income gains were steeper than revenue gains. North America operating income jumped to $8.7 billion from $4.8 billion year-over-year, while AWS operating income rose to $17.8 billion from $11.4 billion. International operating income increased to $1.6 billion from $1.2 billion. Net income fell to $20.7 billion, or $1.89 per diluted share, from $21.2 billion or $1.95 per share, primarily because the prior-year quarter included $9.5 billion in pre-tax gains from Anthropic investments.
The company provided forward guidance in CEO Andy Jassy’s statement, projecting AWS revenue growth rates exceeding 40% in both 2027 and 2028. This represents a modest deceleration from the 39% growth achieved in Q3, suggesting the company expects the current pace to persist rather than accelerate further.
What it means
The margin expansion is real and operational. AWS operating income grew 56% while its revenue grew 39%, indicating the segment is converting incremental sales to profit at a faster rate than top-line growth, a sign of operating leverage as infrastructure investments mature and customer deployments scale. North America operating income nearly doubled while sales grew only 6%, pointing to margin recovery in retail after years of investment in logistics and fulfillment. The company is capturing more of each dollar sold as it optimizes cost structure.
The retail growth deceleration is partly optical. Stripping out the Prime Day timing shift, underlying Q3 retail growth would have been roughly 10%, closer to the company’s historical trajectory. AWS is the true growth engine now, and its 39% expansion, the fastest in nearly five years, suggests the AI infrastructure cycle is accelerating. The company’s emphasis on Bedrock, AgentCore, and custom chips like Trainium indicates AWS is moving beyond compute commoditization into higher-margin managed services and purpose-built hardware.
Capital intensity remains the open question. Free cash flow swung to a $42.4 billion outflow for the trailing twelve months, from a $14.8 billion inflow a year prior, driven by a $94.8 billion year-over-year increase in property and equipment purchases tied to AI infrastructure. The company has not quantified how much of this spending is AWS-specific versus retail fulfillment, nor when it expects returns on this capital to stabilize margins further. If AWS growth sustains above 40% while capital intensity peaks, margin expansion could accelerate; if capital spending persists at current levels without corresponding AWS growth acceleration, margins could compress.
What to watch
AWS guidance for 2027 and 2028 will be tested in the Q4 2026 earnings report (expected early 2027), where the company will report full-year results and provide updated forward guidance. The key metric is whether AWS growth remains in the 39-40% range or accelerates further, and whether the company signals a peak in AI infrastructure spending or commits to sustained elevated capex.
