Amazon Plunges 7% After Hours! Sharing the Same Narrative as Google, Will Amazon Also Suffer an Epic Sell-Off Tomorrow?

After the market closed on October 29, Amazon delivered an earnings report that echoed Google’s at a structural level. AWS revenue reached $45.98 billion, up 39.3% year over year, marking its sixth consecutive quarter of accelerating growth. Operating income rose approximately 55% year over year to $17.773 billion, while its operating margin reached 38.7%, up from 34.6% a year earlier. Group operating income totaled $28.076 billion, with an operating margin of 13.9%, the highest in the company’s history.

The market did not reward these figures. Quarterly purchases of property and equipment reached $77.26 billion, more than double the $35.1 billion recorded a year earlier and over 34% above analysts’ estimate of approximately $58.7 billion. Free cash flow over the past twelve months swung from positive $14.788 billion a year earlier to negative $42.357 billion. At the end of the second quarter, the figure had still been negative $7.6 billion, meaning the shortfall widened by nearly fivefold within a single quarter. Management also indicated that spending would “increase significantly” in 2027.

Google’s version of this script had already played out the previous day: free cash flow of negative $9.07 billion, its second consecutive negative quarter and far worse than the expected negative $2.7 billion. Full-year 2026 free cash flow is projected at negative $12.62 billion, with Goldman Sachs estimating approximately negative $40.57 billion for 2027. The stock closed 13% lower the following day, marking its largest single-day decline since listing.

The same “AI cash burn” narrative, and the same turn to negative free cash flow. But for history to repeat itself, the two companies would need to be sufficiently similar in the composition of their cash flow shortfalls and the assets available to cushion them. Examined layer by layer, the similarities remain at the narrative level; the real differences in pricing lie within the anatomy of the numbers.

Difference One: Different Directions in the “Slope of Deterioration”

At negative $42.4 billion, Amazon’s shortfall is nearly five times Google’s quarterly negative $9.07 billion, making it more alarming in absolute terms. But the market’s pricing of free cash flow depends not only on the size of the shortfall, but also on whether it reflects a one-off surge or a persistent trend.

Amazon’s negative $42.4 billion is measured on a trailing-twelve-month basis. Its deterioration can be traced through two quarter-end snapshots: trailing-twelve-month free cash flow stood at negative $7.6 billion at the end of the second quarter before falling to negative $42.4 billion at the end of the third. The additional $34.8 billion shortfall within one quarter coincided with quarterly capital expenditure jumping from $35.1 billion a year earlier to $77.26 billion, a year-over-year increase of $42.16 billion driven almost entirely by concentrated purchases of AI infrastructure. This represents a concentrated step-up in capital expenditure, rather than an erosion of operating cash flow itself. Trailing-twelve-month operating cash flow reached $168.3 billion, up 29% year over year, indicating that the operating business’s cash-generating capacity is still expanding.

The direction of Google’s cash flow problem is more concerning. Free cash flow has now been negative for two consecutive quarters, with the shortfall widening from $5.855 billion in the second quarter to $9.065 billion in the third. The deterioration is persistent and deepening quarter by quarter. More significantly, operating cash flow fell from $48.4 billion a year earlier to $42.3 billion, a decline of 13%, meaning the operating business’s cash generation is itself contracting while capital expenditure is simultaneously doubling. Amazon’s operating cash flow is growing but has been outpaced by the jump in capital expenditure. Google’s operating cash flow is shrinking, with expanding capital expenditure being layered onto an already thinning cash base.

The implications for pricing differ: Amazon faces the problem of “spending too quickly,” while Google faces “earning less while simultaneously spending more.” The latter’s persistent negative cash flow is harder to reverse in the short term.

Difference Two: Revenue Certainty

The figure in Amazon’s earnings report most obscured by its 7% after-hours decline is AWS’s backlog. CEO Jassy disclosed on the earnings call that AWS’s backlog had reached $578 billion, up further from $496 billion at the end of the second quarter, with triple-digit year-over-year growth. Backlog represents the value of signed contracts that have not yet been recognized as revenue. Its significance lies not in “money already earned,” but in visibility into future revenue. When the market penalizes capital expenditure as “spending without an anchor,” backlog provides that anchor.

Comparing the $578 billion backlog with quarterly capital expenditure of $77.26 billion, the backlog is equivalent to 7.5 quarters of capital expenditure. Jassy also offered a more ambitious outlook: AWS growth would exceed 40% in both 2027 and 2028, with annual revenue potentially surpassing $1 trillion within the next five to ten years. He also disclosed an operational detail: the company installs an AI accelerator every 14 seconds on average, and customers absorb capacity almost as soon as it is installed. AWS capacity through 2028 is “largely sold out.”

Google Cloud’s backlog is also substantial at $561 billion, up 256% year over year. However, it is smaller than AWS’s, while Google Cloud’s absolute operating income of $11.1 billion is well below AWS’s $17.773 billion. More importantly, growth in Google’s core advertising business has slowed for three consecutive quarters, weakening its ability to use internal cash flow to cross-subsidize capital expenditure. Although Amazon’s retail and advertising businesses are also slowing, North American retail operating income reached $8.723 billion, up 82% year over year, with an operating margin of 7.7%. International operating income reached $1.580 billion, up from $1.199 billion a year earlier. The retail business is not contracting; it is generating higher profits at a lower rate of revenue growth.

Difference Three: Amazon Has a Retail “Cushion”

Online store sales reached $68.47 billion, up just 2% year over year, the slowest growth since early 2023. Advertising revenue rose 11% to $19.64 billion, below market expectations of $20.82 billion and the slowest growth since separate disclosure began in 2020. Part of this can be explained by Prime Day shifting from the third quarter to the second. Amazon itself estimates that, excluding this timing effect, third-quarter revenue growth would have been approximately four percentage points higher. Fourth-quarter advertising growth is expected to rebound to nearly 20%.

However, North American retail operating income reached $8.723 billion, up 82% from $4.789 billion a year earlier, with an operating margin of 7.7%. This profit growth far exceeded revenue growth of 6%, indicating improving unit economics in retail. CFO Olszewski disclosed that although transportation costs rose 11% year over year because of higher fuel costs and linehaul rates, the cost to serve each unit is declining through better inventory placement, shorter transportation distances, and package consolidation. It is on track to decline for the fourth consecutive year. Jassy also noted that more than one million robots are now operating across the fulfillment network, already making a meaningful contribution to productivity improvements and lower operating costs.

Google does not have this structure. Search advertising growth slowed from 19% in the first quarter to 17% in the second and 12% in the third, marking three consecutive quarters of slowing growth, with the deceleration becoming more pronounced. Its core advertising business is itself losing momentum, without a retail segment delivering “low revenue growth and high profit growth” to provide an internal cash cushion.

Amazon’s Share Price Outlook for Tomorrow

The two earnings reports’ fourth-quarter outlooks reveal different dimensions of risk. Google did not provide a revenue outlook that worried the market. Its problems center on the sustainability of capital expenditure and cash flow, representing a supply-side risk driven by its own investment decisions. Amazon’s fourth-quarter guidance introduced another variable: revenue of $240 billion to $247 billion, with the midpoint below market expectations of $244.5 billion; and operating income of $28.5 billion to $33.5 billion, with a midpoint of $31 billion, below analysts’ expectations of approximately $33 billion. The market’s interpretation has centered on the possibility that “holiday-season consumption may fall short of expectations.”

This means Amazon faces two overlapping narratives when trading opens tomorrow. One is “AI capital expenditure consuming cash flow,” mirroring Google’s. The other is “marginal weakening in consumer demand,” which Google does not face. However, the direction of the interaction between these narratives is uncertain. If, after the open, the market chooses to believe that the retail slowdown mainly reflects Prime Day’s shift and other timing factors—with fourth-quarter advertising growth guidance of nearly 20% itself providing a counterbalancing signal—the consumer narrative will be partially stripped away, and pricing will converge toward the AI cash flow narrative. If subsequent data confirm that consumer weakness is a sustained trend, the two narratives will compound each other, and the decline could exceed the initial 7% after-hours pricing.

Overall, Amazon will not fully repeat Google’s 13% plunge when the market opens tomorrow. Google’s decline reflected the combined pricing of four factors: “two consecutive quarters of negative free cash flow, shrinking operating cash flow, three consecutive quarters of slowing search advertising growth, and guidance for further capital expenditure expansion.” Amazon exhibits two and a half of these factors: its absolute cash flow shortfall is larger, but operating cash flow is still growing, and a persistent pattern of negative readings across multiple quarters has not yet formed. AWS’s $578 billion backlog and $17.773 billion in quarterly operating income provide a profit anchor of a scale Google Cloud does not have. North American retail profit grew 82% year over year, thickening the cushion even as its coverage narrows because of consumer demand and timing factors. Weak fourth-quarter consumer guidance is an additional variable that Google does not face. It makes Amazon’s pricing more complex, but also more differentiated. The market must assess both “visibility into AI returns” and “short-term noise in consumer demand,” rather than face the straightforward double hit to “cash flow and the core business” seen at Google.

Finally, what this week’s successive reports have truly confirmed is a more fundamental shift in pricing: AI capital expenditure is being repriced from “fuel for growth” to “a burden with uncertain returns,” and this framework is no longer being applied to just one company. But Amazon holds two cards that Google does not: $578 billion in signed orders and $8.7 billion in quarterly retail profit. The 7% after-hours decline suggests that while the market acknowledges the mismatch, it has not yet fully removed those two cards from its valuation. The real test comes in the fourth quarter. If AWS’s backlog begins converting into revenue at a growth rate above 40%, while retail profit margins remain above 7% after the holiday season, the current 7% discount will be reassessed. If the persistent negative free cash flow deepens further in the fourth quarter, while cracks in consumer demand shift from “timing noise” into a trend signal, those two cards will be withdrawn one by one.
