Amazon Free Cash Flow Turns Negative on AI Spending

Amazon free cash flow just fell off a cliff, and Wall Street noticed fast. The company reported on Thursday that it burned forty-two point four billion dollars over the twelve months ended September thirtieth, flipping from a positive fourteen point eight billion a year earlier, according to Axios.

The numbers behind the miss

Third-quarter net sales rose twelve percent to two hundred one point nine billion dollars, per Amazon's own earnings release. Earnings came in at one dollar eighty-nine a share. Analysts had expected about one ninety-six, according to CNBC, so the company missed on both the top and bottom line.

The weirdest part is that the business itself looked strong. Operating income hit twenty-eight point one billion dollars, and the operating margin of thirteen point nine percent was the highest Amazon has ever posted. AWS operating income climbed to seventeen point eight billion, up from eleven point four billion a year ago.

Where all the cash went

Capital spending is the culprit. Amazon spent seventy-seven point three billion dollars on capex in the quarter alone, far above the roughly fifty-eight point seven billion analysts had pencilled in, according to CNBC TV18. A year earlier, the same quarter was thirty-five point one billion.

The company said the swing came mostly from a ninety-four point eight billion dollar jump in purchases of property and equipment tied to AI. For all of this year, Amazon is holding its capex forecast at two hundred twenty billion dollars, largely for AI data centres.

How the market reacted

Shares closed Thursday at two hundred forty-three seventy-nine, down four point three percent, then slid roughly seven percent in extended trading, according to the Associated Press. CNBC reported the stock was down about seven percent premarket on Friday.

The company also gave a cautious outlook. Amazon expects fourth-quarter net sales between two hundred forty and two hundred forty-seven billion dollars, and Yahoo Finance noted its operating income guidance fell short of what investors wanted.

Jassy doubles down

CEO Andy Jassy told investors he still expects to spend two hundred twenty billion dollars this year, and he believes AWS sales will grow forty percent in each of the next two years. He also said the cloud unit could ultimately become a business worth more than a trillion dollars within five to ten years, per the AP.

That is a huge bet, and it is the kind that makes the Amazon free cash flow number so jarring. Cash flow from operations actually rose twenty-nine percent to one hundred sixty-eight point three billion dollars, but spending on servers, chips and buildings swallowed all of it and then some.

A selloff bigger than one company

Amazon was not alone on Thursday. According to Reuters, the drop mirrored a broader tech selloff after Intel warned of weak PC revenue, and Alphabet shares fell twelve percent in the regular session, its worst single-day percentage decline ever.

Put together, the message from investors is blunt. Big tech can keep spending hundreds of billions on AI, but the market now wants to see clearer proof that the money turns into profit. Amazon's record margin helped, yet it was not enough to calm nerves about a cash burn that doubled down from the earlier quarter's seven point six billion dollar outflow.

The next few quarters will show whether AWS growth speeds up enough to justify the build-out. If it does, today's panic may look like a blip. If it does not, expect more pressure on every company racing to build AI data centres.

Why Gen Z should care

If you shop Prime, stream on it, or want a job in tech, this matters. Amazon is basically proving how expensive the AI race is, and investors are starting to ask when the payoff arrives. Negative free cash flow for two quarters in a row means the company is leaning on its balance sheet to keep building.
