Amazon’s AWS Surge: 37% Growth Signals AI Payoff Amid Surging Capital Bets

Amazon delivered numbers that sent shares soaring more than 15% in after-hours trading. Total revenue hit $200.6 billion. That topped forecasts. But the real story sat inside AWS. The cloud unit posted $42.2 billion in sales. Growth reached 37%. It marked the fastest pace in 18 quarters.

AWS Momentum Outpaces Expectations and Rivals

Analysts had penciled in about 31%. Amazon cleared that bar with room to spare. The division now runs at a $169 billion annualized pace. Its backlog swelled to $496 billion. That figure grew in triple digits from the prior quarter. And growth has accelerated for five straight periods.

Andy Jassy didn’t mince words. “AWS is booming, growing 36.7% year-over-year in Q2—our fastest growth in 18 quarters—and our AI and Chips businesses each eclipsed run rates of more than $25 billion,” the Amazon CEO said in the company’s earnings release. The quote captured the dual engine at work. Core cloud services kept expanding. AI workloads added fresh fuel.

Operating income for AWS climbed to $16.6 billion. The margin expanded to 39.4%. That’s up 650 basis points from a year earlier. Efficiencies helped. So did capacity optimization. Yet the bigger picture involves heavy spending. Amazon raised its 2026 capital expenditure forecast to $220 billion. The $20 billion bump reflects higher memory costs and insatiable demand for infrastructure.

Free cash flow turned negative on a trailing basis. The outflow reached $7.6 billion. Purchases of property and equipment jumped $66.1 billion year over year. Investors shrugged it off. They saw the revenue acceleration as proof that bets on AI infrastructure are starting to pay. The Wall Street Journal noted shares jumped as cloud sales and spending both accelerated. Customers keep signing longer commitments. Many stretch five years or more.

Jassy painted a picture of uneven but powerful adoption during the earnings call. AI labs sit at one end of a barbell. They consume “gobs and gobs of compute.” Enterprises chasing cost savings occupy the other. In between sit current production workloads. Those represent the largest absolute segment. “I don’t know if the trajectory of that middle part of the barbell will be the same wildly steep trajectory that we’ve seen with the current barbelled AI Labs piece,” he cautioned, per analysis in Tom Tunguz’s breakdown.

Still, the linkage looks clear. As customers pour money into AI, their core consumption on AWS rises too. That dynamic should strengthen once more workloads reach production scale. The company added over $4.6 billion in sequential AWS revenue. That was 80% larger than any prior increase. Impressive when the base now exceeds $30 billion per quarter.

Chips tell part of the tale. Amazon’s homegrown silicon passed the $25 billion run-rate mark with triple-digit growth. Trainium drew multi-gigawatt, multi-year commitments from Anthropic and OpenAI. Startups jumped on board too. Names like NEURA Robotics, TwelveLabs, and Poolside signed on. Graviton5 launched with 30% to 40% better price-performance.

Bedrock, Amazon’s model-hosting service, added more than 10 foundation models. Offerings now include the latest from OpenAI, Anthropic, Google DeepMind, and others. Hundreds of thousands of customers use it. Spending there rose in the quarter. Agentic tools gained traction. Kiro, a coding agent, tripled usage sequentially and delivers up to 50% better cost efficiency.

But the spending pace raises questions. Data centers take two years to come online. Servers and networking break even in less than three years against five-to-six-year lives. AI capacity contracts run at least five years. Jassy sounded unconcerned about returns. “If the demand isn’t there, we won’t spend the capital,” he said on the call. Capacity will remain tight through 2026 and 2027. Demand for 2028 already looks striking.

Comparisons to rivals sharpen the picture. AWS narrowed Microsoft’s Azure lead from 16 percentage points to six. Google Cloud shows faster recent acceleration in some metrics. Yet AWS still holds the largest base. Its $496 billion backlog remains the smallest of the three hyperscalers despite leading revenue. That suggests plenty of room to convert commitments into recognized sales over time.

Companywide results reinforced the positive tone. Operating income rose 43% to $27.5 billion. Net income jumped to $62.6 billion, or $5.75 per share. A $53.4 billion non-operating gain from investments, largely tied to Anthropic, inflated that figure. Advertising revenue grew 26% to nearly $20 billion. Stores saw record delivery speeds. Prime members received over 40% more items same-day or overnight.

The retail side doesn’t get the same headlines anymore. AWS carries the growth story. It also drives the capital plan. Tom Tunguz projects that sustained 20% growth could push AWS alone to $1 trillion in annual revenue within about a decade. Faster rates shorten the timeline. At current multiples, that scenario implies a much larger Amazon valuation. Jassy has upgraded his long-term view on the cloud unit from “a few hundred billion” to “at least double that” and potentially the trillion-dollar mark.

Recent coverage echoes the optimism. CNBC highlighted how AWS trounced estimates and noted Jassy’s comment that capacity shortages will persist. The Quarterly pointed out total revenue crossing $200 billion for the first time in a quarter. Yahoo Finance recapped the backlog surge and margin gains.

Challenges remain. Memory prices climbed. Supply volatility could worsen with tariffs or geopolitics. Free cash flow may stay under pressure while build-out continues. Yet the market reaction spoke volumes. Bulls wanted evidence that massive AI outlays would translate into revenue. They got it. AWS added revenue at a record clip while expanding margins. The backlog signals visibility for years ahead.

Amazon isn’t alone in chasing AI infrastructure. Every major cloud provider reports strong demand. The difference lies in execution and differentiation. Custom chips, agentic tooling, and a massive installed base give AWS advantages. Whether the middle of that adoption barbell ignites as strongly as the labs end will determine how quickly the trillion-dollar vision materializes. For now, the numbers point higher. Much higher.

So the fastest growth in 18 quarters may indeed not be the best part. The combination of accelerating sales, expanding profitability, and visible demand well into the future paints a picture of sustained outperformance. Even with capital spending at record levels. Especially with it.
