Amazon (AMZN) Filing Discloses $578 Billion AWS Backlog

AWS Backlog Hits $578 Billion

Amazon disclosed a $578 billion backlog at its cloud business in the Q3 2026 earnings release filed with the SEC, and shares fell more than 7% in after-hours trading once results missed estimates. Backlog is the contracted-but-not-yet-recognized revenue line, and it has become the number investors track against delivered capacity. Amazon (AMZN) grew AWS sales 39.3% to $46 billion in the same period, so contracted work is piling up at a rate the recognized revenue line is not matching. The release also showed trailing free cash flow swinging to an outflow of $42.4 billion from an inflow of $14.8 billion a year earlier, a swing large enough to put the spending program under scrutiny. On the earnings call, management put the sequential backlog increase at $82 billion from the second quarter, while quarterly AWS sales added only $3.8 billion; the quarter before, AWS had added $4.6 billion in sequential sales, so the latest step-up in orders was more than double the step-up in revenue. A year earlier the backlog stood at $200 billion, meaning the order book has nearly tripled while sales grew 39.3% over the same span. Jefferies analyst Brent Thill argued cloud providers cannot convert backlog into revenue as quickly as investors want, and identified data center and supply chain bottlenecks as the binding constraint. CEO Andy Jassy, who said last quarter that Amazon lacked capacity to meet 2026 demand and expected the shortfall to persist into 2027, told investors the company installs an AI accelerator roughly every 14 seconds and that customers absorb that capacity almost as fast. The gap between what customers have signed and what Amazon can switch on is now the central question for the stock, and the fourth-quarter report will show whether capacity additions began closing it.

A 40% Growth Projection Against a Larger Capex Bill

AWS growth is projected above 40% in both 2027 and 2028, an outlook that assumes the delivery constraint gets resolved rather than tightens. The unit's growth has accelerated for six consecutive quarters, from 20% in the third quarter of 2025 to the 39.3% just reported, so each successive base is larger and the revenue a delivery delay leaves on the table grows with it. To close that gap, Amazon plans to spend substantially more next year than the roughly $220 billion budgeted for 2026, a 2026 figure the company raised from $200 billion last quarter, citing higher memory costs. Cash capital spending already reached $75.9 billion in the third quarter alone. Profitability moved the other way: AWS operating income rose to $17.8 billion from $11.4 billion a year earlier, so the cloud unit earns more even as the cash bill climbs. Sector context matters. Microsoft and Alphabet reported a day earlier, and all three big tech earnings reports centered on AI infrastructure bills rather than on consumer or advertising lines. That frames Amazon's backlog in a pattern common across three hyperscalers: AI capacity signed faster than data centers can be energized. If delivery keeps lagging orders, investors may start judging these companies on data centers switched on rather than contracts signed. The offsetting case is mechanical: faster capacity additions narrow the backlog-to-revenue gap and ease pressure on the spending plan. Next year's capex was not quantified beyond “substantially more”, and no firm AWS revenue figure for 2027 accompanied the growth projection, so the next filing carries the burden of turning a $578 billion order book into a delivery schedule.

AMZN at $227.67 With the Downtrend Intact

Live COINOTAG data puts AMZN shares at $227.67, down 10.09%, inside a 24-hour range of $214.51–$254.00. The composite scoring rates $219.84 as the strongest support below the market, at 74 out of 100, and puts the nearest resistance at $251.10, scored 80/100. Momentum readings are weak: the daily RSI sits at 28.8 and the MACD signal is bearish, matching the daily downtrend reading. A decisive close under $219.84 would put the lower end of the recent range back in play; reclaiming $251.10 would require the delivery picture to change first.
