Amazon Q3 2026 Earnings: What AWS's 39% Growth Means

Some earnings reports are about one number. Amazon's third quarter of 2026 was about two: a record operating margin and the fastest cloud growth in nearly five years. Amazon reported results on October 29, 2026, and CEO Andy Jassy used the call to make a big claim about where AWS is headed. Let's break down what actually moved, without the hype.

• Revenue: net sales up 12% to $201.9 billion, or 13% excluding currency effects
• AWS: sales up 39% to $46.0 billion, a $184 billion annualized run rate, with a $578 billion backlog
• Profitability: operating income of $28.1 billion and a 13.9% operating margin, Amazon's highest ever
• Q4 guidance: net sales of $240 billion to $247 billion and operating income of $28.5 billion to $33.5 billion

How Fast Is AWS Growing in Q3 2026?

AWS grew 39.3% year over year, its sixth straight quarter of acceleration and its fastest growth in nearly five years, according to Amazon. Segment operating income jumped to $17.8 billion from $11.4 billion a year earlier. For context, back in Q2, AWS grew 37%, so the trend line keeps pointing up.

Jassy shared a few stats that explain why:

• AI capacity: AWS is installing an AI accelerator roughly every 14 seconds, and customers are using new capacity almost as fast as it comes online, as The Register also reported from the call
• Bedrock: total token volume on Amazon's AI inference service grew nearly 17x year over year, making it the fastest-growing multi-billion-dollar service in AWS history
• Custom chips: revenue commitments for Graviton and Trainium each rose more than 20x year over year
• Core cloud: compute and storage revenue grew at their fastest rates in several years

Jassy also said Amazon projects AWS growth above 40% in both 2027 and 2028, and floated the idea that Amazon could run two trillion-dollar revenue businesses within five to ten years. Those are management projections, not guarantees, but they show how much conviction is behind the spending.

What About Amazon's Retail Business?

The stores side grew more slowly but more profitably. North America sales rose 6% to $112.9 billion, with segment operating income climbing to $8.7 billion from $4.8 billion. International sales rose 5% to $43.1 billion. Amazon notes that Prime Day shifted into Q2 this year, and says third-quarter growth would have been roughly 4 percentage points higher without that timing change.

Net income came in at $20.7 billion, or $1.89 per diluted share, slightly below last year's $21.2 billion. The difference is mostly last year's $9.5 billion investment gain tied to Anthropic, not weaker operations.

Why Free Cash Flow Is the Number to Watch

Here's the part long-term investors should sit with. Trailing twelve-month operating cash flow rose 29% to $168.3 billion, which is excellent. But free cash flow swung to an outflow of $42.4 billion, because spending on property and equipment jumped by $94.8 billion, mostly for AI. Amazon still expects roughly $220 billion of capital expenditure in 2026.

If that term is new to you, our plain-English guide to free cash flow explains why it matters. The short version: Amazon is choosing to reinvest heavily now, betting that faster AWS growth and AI margins that Jassy says are already well ahead of where core cloud was at a similar stage will pay that back.
