AWS Backlog Reaches $496 Billion After Quarterly Increase of $130 Billion
Key Facts
AWS’s backlog reached $496 billion in the second quarter of 2026, up $130 billion from the previous quarter, according to Seeking Alpha’s analysis of Amazon’s reported figures. That came as the cloud computing unit’s revenue grew 36.7% year over year to $42.2 billion, marking the fifth consecutive quarter of accelerating growth for the segment. CEO Andy Jassy said AWS cloud capacity is “largely booked through 2027,” with significant commitments extending into 2028. The contracted demand puts the cloud business at the center of attention ahead of Amazon’s next results, as investors focus on the company’s ability to convert bookings into realized revenue. The scale of demand also stands alongside major capital investment, making execution and cash flow part of investors’ assessment of AWS’s performance.
The backlog reflects the breadth of AWS’s customer base. Unit CFO John Felton said the balance is approaching $500 billion and includes commitments from large AI labs and major companies, as well as small and midsize businesses. According to Jassy, much of 2028 capacity has already been sold, while Amazon is holding back some capacity for on-demand services such as Bedrock and EC2. That means advance bookings do not necessarily account for all capacity available for service, as the company leaves room to meet demand as it arises. Seeking Alpha described 2027 capacity as largely booked and said demand for 2028 remains strong. These bookings matter because they offer an indication of future demand, while their conversion into revenue still depends on capacity being provided and brought online.
AWS posted an operating margin of about 39.4% in the second quarter of 2026, according to Seeking Alpha, alongside revenue growth that accelerated for the fifth consecutive quarter. The margin provides context for assessing the backlog: the metric reflects not only the volume of business awaiting fulfillment, but also the profitability of the unit that will provide the services. Felton said AWS is generating returns on AI server investments in less than 3 years. That estimate provides a time frame for returns on part of the spending supporting infrastructure expansion. But the backlog figure alone does not show when revenue will be recognized or how expansion will affect cash flow, two factors analysts will be watching in the next results.
Meanwhile, Seeking Alpha said expected cash capital spending for 2026 is $220 billion, and free cash flow for the twelve months ended October 2026 was negative $7.6 billion. That heavy spending puts cloud growth up against the cost of building the data centers and servers needed to meet bookings. As a result, scrutiny of the results goes beyond whether demand is strong; it also includes whether Amazon can execute its expansion and earn returns while managing the investment’s effect on liquidity. Felton’s estimate that AI server costs are recovered in less than 3 years remains a company indicator of the expected return on that investment. The negative cash flow figure shows that ongoing spending is weighing on available cash, according to the analysis, though it does not by itself determine the trajectory of cash flow in subsequent periods.
Amazon’s third-quarter guidance calls for revenue of between $197 billion and $202 billion, according to Seeking Alpha. The analysis described the guidance as appearing weak, but attributed most of the apparent slowdown to Prime Day shifting into the second quarter and to foreign exchange effects. The quarter-on-quarter comparison therefore differs in part because of the timing of the retail event, while currency moves may affect reported revenue. The guidance comes as AWS growth accelerates, putting the cloud unit’s performance alongside total revenue in the assessment of the company’s results. In reading the third quarter, actual figures will indicate how the business is tracking against the guidance range, while the $496 billion backlog remains a measure of pending commitments rather than revenue already realized.
Amazon is scheduled to report third-quarter results on October 29, giving investors a chance to compare actual revenue with the company’s guidance of between $197 billion and $202 billion. Amazon shares closed at $248 on October 23, 2026, according to EL7 data; that closing price alone does not determine the market’s direction or reaction to second-quarter results. Shares had risen more than 9% in after-hours trading on July 30 following the second-quarter results, according to the Associated Press. The agency noted that investors were assessing whether the company’s AI spending had begun to pay off. The October 29 results will put AWS’s accelerating growth, backlog, capital spending and cash flow among the first indicators investors watch for the next period.
