Amazon’s third-quarter results made one number unavoidable. Amazon Q3 AWS 39% Growth marked the cloud unit’s fastest expansion in nearly five years, with revenue climbing to $45.98 billion and beating Wall Street’s $45.29 billion consensus, the company reported on October 29, 2026. CEO Andy Jassy used the earnings call to set a bold bar for the future, saying he expects AWS to grow more than 40% in both 2027 and 2028. Investors were not celebrating: with earnings missing estimates, Amazon shares fell more than 7% in after-hours trading.

What Was Announced?

Amazon Web Services posted revenue of $45.98 billion in Q3 2026, up 39% from a year earlier, according to the company’s earnings release. That is the fastest growth the unit has recorded in nearly five years, and it came with operating income of $17.8 billion at a 38.7% margin, CNBC reported. Jassy told analysts on the call that AWS is now projecting growth “of more than 40% in both 2027 and 2028.”

At the parent-company level the print was more mixed. Amazon reported total revenue of $201.9 billion, up 12% and just under estimates, with earnings of $1.89 per share against the $1.97 analysts expected, as higher interest costs on its growing debt and other losses offset an operating income beat. In fact, operating income rose 61% year over year to $28.1 billion, a 13.9% margin Amazon called its highest ever, GeekWire reported.

The AI Spending Bill Comes Due

Backing that growth is a capital program of historic scale. Amazon expects to spend roughly $220 billion on capital projects in 2026 and “meaningfully more” in 2027, Jassy said on the call. Third-quarter spending on property and equipment alone hit $77.3 billion, nearly $20 billion above what analysts expected.

The bill shows up in the cash flow statement. Trailing twelve-month free cash flow swung to an outflow of $42.4 billion, compared with an inflow of $14.8 billion a year earlier, reflecting heavy AI infrastructure investment. Meanwhile, AWS disclosed a contracted-revenue backlog of $578 billion, more than double a year ago, a pipeline Jassy is betting will justify the spending.

Jassy was characteristically expansive about the destination: “There has never been a trillion dollar revenue business, and we may have two of them in the next 5-10 years,” he said, naming AWS and Amazon’s stores business. AWS now runs at a $184 billion annual revenue pace and came within about $500 million of third-party seller services as the company’s second-largest source of sales.

Amazon also flagged a drag on the fourth quarter: costs for Amazon Leo, its satellite internet service, are weighing on the profit forecast as the service prepares to launch later this year. The company guided Q4 revenue of $240 billion to $247 billion and operating income of $28.5 billion to $33.5 billion.

Why It Matters

Amazon’s report rounds out an AI-infrastructure earnings week, and it tells the same story each time: accelerating cloud demand keeps colliding with capital spending that is now visibly flattening free cash flow, AI Weekly noted. For AWS, 39% growth at a nearly $46 billion quarterly scale is the strongest evidence yet that enterprise AI workloads are pulling cloud spending forward.

The question Jassy is asking investors to answer is whether they will tolerate being, as Amazon’s own lore puts it, misunderstood for long periods of time while the capex bills arrive years before the revenue does. The backlog figure, $578 billion and doubling, is his answer. Wall Street’s reaction, a 7% after-hours slide, suggests the answer is still being negotiated.
