Amazon's AWS Hits 39% Growth, but a $42.4B Cash Outflow Sinks the Stock — AMZN −4.25% at Close, About −9% After Hours

Takeaway

Amazon delivered its fastest cloud growth in nearly five years and its highest operating margin on record, and the stock was still sold: it fell 4.25% in the regular session on Thursday and was quoted roughly 6% to 9% lower after hours depending on the time of the quote. The market is weighing a diluted earnings per share miss and a trailing free cash flow outflow of $42.4 billion, which Amazon ties to AI investment, against AWS acceleration. For the AI-infrastructure trade, the message is that growth is being judged against the cash it costs.

What happened (source + time ET)

Amazon released third-quarter results after the 4:00 PM ET close on Thursday, October 29, 2026 (company release; the earnings call was scheduled for 5:00 PM ET). Figures from the release, versus a year earlier:

• Net sales rose 12% to $201.9 billion from $180.2 billion (13% excluding a $0.9 billion foreign-exchange headwind).
• AWS sales rose 39% to $46.0 billion from $33.0 billion, which Amazon called its fastest growth in nearly five years. AWS operating income was $17.8 billion versus $11.4 billion.
• Operating income was $28.1 billion versus $17.4 billion, a 13.9% margin that Amazon called its highest ever.
• Net income was $20.7 billion, or $1.89 per diluted share, versus $21.2 billion, or $1.95. Amazon attributed the decline mainly to $9.5 billion of pre-tax gains from Anthropic investments booked in the third quarter of 2025.
• Trailing-twelve-month free cash flow was an outflow of $42.4 billion, versus an inflow of $14.8 billion a year earlier, driven mainly by a $94.8 billion year-over-year increase in property and equipment purchases that Amazon links to AI investment.
• Fourth-quarter guidance: net sales of $240.0 billion to $247.0 billion (12% to 16% growth) and operating income of $28.5 billion to $33.5 billion, versus $25.0 billion a year earlier.
• Amazon said it continues to expect 2026 cash capital expenditures of approximately $220 billion. An aggregator summary of the call also reports management expects to spend "meaningfully more" in 2027; we could not confirm that wording against a transcript, so treat it as reported, not verified.

Share-price context: the regular session closed at $243.79, down $10.81, or 4.25% (Motley Fool, as of 4:00 PM ET). After hours, Benzinga coverage cited in BudFox desk note #224 showed Amazon at $222.12, down 8.89%, at 4:20 PM ET. Other outlets described a drop of about 6% in early after-hours trading and "more than 7%". These are quotes at different moments in a thin, moving after-hours market, not a disagreement about the print. One aggregator cites an earnings per share consensus of $1.97 from FactSet; Amazon's reported $1.89 sits below that.

Mag7 impact (with tape numbers)

Amazon is the direct name. The after-hours reaction puts a number on a question that has run through this earnings week: whether accelerating cloud revenue justifies the capital spending behind it. Alphabet and Microsoft reported earlier this week and were part of that same debate, and Amazon's reaction extends it. A reaction this large to a print where the cloud segment beat suggests the market is currently rewarding cash discipline more than growth alone.

For the suppliers of AI hardware, the read is mixed. A reaffirmed capital spending plan of about $220 billion is a large, continuing source of demand for data-center equipment, and Amazon expects to keep spending. The same print shows the market punishing the cash cost of that demand, which can matter for how long hyperscalers are willing to hold spending at these levels. Nvidia is the most direct beneficiary of the spending but has not reported tape movement tied to this release, and we do not have verified post-print data for it.

Tape / technicals

Amazon (AMZN), BudFox tape as of Thursday, October 29, 6:05 AM EDT (before the open and before the print; not live):

• RSI(14): 50.1. That is mid-range momentum, neither stretched nor oversold.
• Trend vs EMA20: +0.07%, meaning the price was sitting essentially on its 20-day exponential moving average.
• RVOL: 0.96x, about typical volume against the 20-day average.
• IV30 versus realized: 30-day implied volatility of 47.5 against 20-day realized volatility of 32.7, so options were pricing more movement than the stock had been delivering going into the print. That is context, not a trade.

These readings predate Thursday's 4.25% regular-session decline and the after-hours move, so they describe where Amazon stood going into the report, not where it stands now. Last price, session move and relative performance versus the S&P 500 are omitted because the tape's price fields are premarket and no longer reflect the close.

Desk read

Amazon (AMZN): Neutral. Confidence: Medium. Cloud growth of 39% and a record margin are real positives, but a $42.4 billion trailing cash outflow and a reaffirmed $220 billion spending plan give the market a reason to wait for evidence that capital spending converts to cash. The tape going in was mid-range, so the move reads as a reaction to the print rather than an already-stretched stock unwinding.

Nvidia (NVDA): Tailwind. Confidence: Low. Amazon holding its roughly $220 billion capital spending plan keeps a large buyer of AI infrastructure in the market, though the stock reaction shows tolerance for that spending is being tested.

What would change this view: a clearer path for free cash flow to recover, or a capital spending outlook that grows faster than cloud revenue.

What to watch

Amazon's opening price on Friday against the after-hours quotes, and whether the pattern of spending being punished carries to other AI-infrastructure names. Management commentary on 2027 capital spending, AWS capacity constraints, and the timeline for free cash flow to turn. Whether the reported "meaningfully more" language for 2027 is confirmed in the call transcript. The Prime Day timing shift into the second quarter, which Amazon said held back third-quarter net sales growth by about 400 basis points, as the fourth-quarter retail guide comes into focus.
