Amazon Q2 2026: AWS Posts Fastest Growth in 18 Quarters at 37% as Capex Jumps to $220B
Amazon’s cloud computing unit, Amazon Web Services, posted thirty-seven percent year-over-year revenue growth in the second quarter of 2026, the fastest pace in eighteen quarters, and prompted the company to lift its full-year capital spending forecast to two hundred and twenty billion dollars to keep pace with runaway demand for AI infrastructure. The result, disclosed on Thursday, marks the clearest sign yet that Amazon’s multi-year bet on AI and custom silicon is starting to convert into top-line growth.
The growth rate in the April-June period exceeded the twenty-eight percent clip in the first quarter and is the highest since the cloud unit’s early surge in 2021. The report also arrived with a higher-than-expected earnings beat, which sent shares of Amazon up sharply in after-hours trading. The combination of accelerating cloud growth and an upward revision to capital spending is the strongest signal yet that Amazon’s AI investments are paying off, even as the spending numbers continue to grow faster than most analysts had modeled.
What the Numbers Show
AWS revenue grew thirty-seven percent year over year to one hundred and nine billion dollars for the quarter, with the run rate exceeding the trailing-twelve-month revenue of the entire cloud business a year ago. The growth rate is the fastest since the first quarter of 2022, when the segment was still recovering from post-pandemic normalization. The cloud unit’s operating margin also expanded, reflecting the leverage that comes from fuller datacenter utilization and the higher contribution of AI workloads to the revenue mix.
Amazon’s total capital spending for the year is now expected to reach two hundred and twenty billion dollars. That figure is up from a two hundred billion dollar plan announced in February and well above the one hundred and twenty-eight billion dollars the company spent on capital expenditures in all of 2025. CEO and President Andy Jassy disclosed the new total on the company’s earnings call, noting that the increase reflects the cost of memory chips, semiconductors, robots, and satellites, in addition to the standard cloud datacenter buildout.
The new capex figure is large enough to draw fresh attention to the question of how Amazon will fund the investment. The company has free cash flow that comfortably absorbs the capex, but the magnitude of the ramp will reshape the operating cash flow profile for the next several years. Investors who have been waiting for cloud profitability to translate into shareholder returns will need to weigh the trade-off between reinvesting in capacity and returning capital.
Why AWS Is Reaccelerating
Three factors are converging to push AWS growth back to its fastest pace in years. First, enterprise adoption of generative AI workloads has moved from pilots to production, and many of those workloads are running on AWS because of the company’s early investment in custom Trainium and Inferentia silicon and because of its leading position in the Bedrock managed model service. Second, demand for custom silicon partnerships is increasing, with the AWS Graviton and Trainium processors now anchoring large portions of the cloud’s compute footprint. Third, the company has been signing multi-billion-dollar deals with the leading AI labs, including OpenAI, Anthropic, and Meta, all of which require hyperscale infrastructure for training and inference.
Jassy said on the call that AWS’s AI and chip businesses each eclipsed run rates of more than twenty-five billion dollars. He added that the cloud unit is “booming” and noted that demand for capacity is outpacing Amazon’s ability to bring new datacenters online. The demand profile has extended to 2028, and Jassy told investors that even at the two hundred and twenty billion dollar capex level, Amazon will not have enough capacity to meet all the demand it has for this year.
What the Capex Ramp Means for the Industry
Amazon’s higher capex is the latest signal that the AI infrastructure build-out is far from over. Microsoft, Alphabet, and Meta have all raised their capital spending forecasts for 2026 in the past two quarters, and the four largest US hyperscalers are now expected to spend more than seven hundred billion dollars combined on AI infrastructure this year. That total is up from roughly four hundred billion dollars in 2025 and reflects the scale of compute demand that the major AI labs are placing on the cloud providers.
The spending is also pulling adjacent markets along. Memory chipmakers, including the Korean giants, have cited AI server demand as the primary driver of recent record earnings. Networking equipment vendors, custom silicon design partners, and datacenter construction firms are all seeing order books grow faster than capacity. The supply chain that supports AI infrastructure is now a more visible component of the broader tech sector than it has been in any prior cycle.
For Amazon specifically, the trade-off is straightforward. Higher capex today funds the capacity that drives AWS growth tomorrow, but it also reduces the cash that could otherwise flow back to shareholders. The next several quarters will tell us whether the company can maintain the growth trajectory while still managing the working capital and free cash flow implications of a two hundred and twenty billion dollar annual spend.
What to Watch
Three signals will tell us whether the second-quarter acceleration is a one-time base effect or the start of a structural step-up. First, the AWS growth rate in the third quarter, when the year-ago comparison becomes tougher. Second, the cadence of AWS deal signings with frontier AI labs, which is the most visible leading indicator of capacity demand. Third, the broader hyperscaler capex numbers from Microsoft, Alphabet, and Meta, which will tell us whether Amazon’s higher guidance is consistent with industry-wide demand or a more aggressive share gain.
For now, the second-quarter print is the strongest evidence yet that Amazon’s strategy of investing through the AI infrastructure cycle is bearing fruit. The capex ramp is uncomfortable for investors who want to see more cash returned, but the growth profile on the other side is exactly what the bull case has been promising for three years.
