Amazon Posts $42.4 Billion Free Cash Flow Outflow in Q3 as AWS Sales Rise 39%
Amazon posted negative free cash flow of $42.4 billion in the third quarter of 2026, according to CNBC, which reported the results on October 29. Free cash flow is the cash a company generates from operations after capital spending. A negative figure means the company spent more on servers, buildings and other equipment than its operations brought in as cash.
The same quarter produced a strong operating line. Amazon's third-quarter release reported operating income of $28.1 billion and an operating margin of 13.9%, which the company described as its highest operating margin ever. Operating margin is operating income divided by net sales. It measures how much of each sales dollar remains after the cost of running the business, before interest and taxes.
Amazon Web Services carried much of the top-line growth. The release reported AWS net sales up 39.3%. Reuters put AWS revenue at $46 billion for the quarter ended September, a 39% increase. Earnings per share came in at $1.89, against an estimate of $1.96, according to CNBC.
The cash line is where the quarter diverges from the income statement. Looking at the four most recent quarterly releases in sequence, free cash flow fell to $11.2 billion in the fourth-quarter results released February 5, then to $1.2 billion in the first quarter reported April 29. In the second quarter, reported July 30, it turned into an outflow of $7.6 billion. The third-quarter outflow of $42.4 billion is a sharp step beyond that trend.
Capital spending explains much of the gap. Purchases of property and equipment were $50.7 billion in the fourth-quarter results, $59.3 billion in the first quarter and $66.1 billion in the second quarter. Each of those three quarters moved higher than the last. What CNBC did report is that Amazon held its 2026 capital expenditure forecast unchanged.
In my view, that unchanged forecast matters more than any single quarter's cash figure. A company that absorbs a $42.4 billion outflow and leaves its full-year spending plan intact is signaling that the build-out is not being slowed to protect quarterly cash. Whether that is the right call depends on what the spending returns. The operating margin is the best evidence in the release that the existing business is paying its way, but operating income is an accounting measure. It does not show how quickly the capital already committed will convert into cash.
Andy Jassy's long-range ambitions sit on top of that trade-off. On October 30, GeekWire reported that Jassy said AWS and Amazon's stores business could each reach $1 trillion in annual revenue within the next five to 10 years. A decade-long revenue target is an aspiration, not a forecast of cash flow or margin, and it says little about the timing of the payback on capital spent this year. For an expert reader, the more useful comparison is between the growth rate in AWS sales and the cash the segment's spending requires.
The next readings that matter are the ones that test whether operating income keeps pace with capital intensity. Amazon's third-quarter figures show the company with strong profit at the operating level, a negative free cash position, and a spending plan that has not been cut. Those three facts sit together uneasily, and the coming quarters will show which of them moves first.
