The valuation gap is smaller than the business gap
Amazon closed Friday at $251.52 and Alphabet's non-voting Class C stock, GOOG, at $340.35. Their share prices tell us little about relative value. The more useful comparison is what each price asks the business to deliver.
At those prices, Amazon trades at 30.3 times estimated FY2026 adjusted earnings, versus 28.8 times for Alphabet. On FY2027 estimates, the figures become 24.0 and 22.6 times. Neither forecast is a promise. The estimates come from the same provider, with Amazon updated September 30 and Alphabet October 1; both fiscal years end in December. These are fiscal-year multiples, not next-twelve-month multiples. Amazon estimates · Alphabet estimates
The revenue bars separate reported years from forecasts. The P/E panel holds today's price fixed and changes the earnings year. It does not reconstruct historical forward P/E using estimates that investors did not have at the time.
The social-media claim that Amazon could double and remain undervalued needs more than rising revenue beside a falling multiple. Doubling its price with the FY2027 estimate unchanged would make the multiple 48 times, rather than 24. That could only be justified by a view about future growth, cash returns and risk; the chart alone cannot establish it. This is an arithmetic check, not a price target.
Amazon's case: the bigger cloud engine
AWS produced $42.2 billion of quarterly revenue, against $24.8 billion at Google Cloud. AWS's reported operating margin was 39.4%, versus 35.6% for Google Cloud. Google Cloud grew much faster from its smaller base: 81.8%, compared with 36.8% calculated from AWS's reported revenue. Both expanded their segment margins. Amazon Q2 results · Alphabet Q2 results
This is a comparison of reported segments. Google Cloud includes Workspace, and Alphabet leaves some shared AI research costs outside its segments. The margin spread is not a clean measure of which company delivers identical computing services more efficiently.
Amazon's investment case is that a large, profitable cloud operation can grow into the infrastructure being built, while retail and advertising contribute additional operating leverage. Alphabet's case is that faster cloud expansion can broaden an already substantial search-and-advertising business. Those are different ways to earn a return on AI spending. Neither is proved by capacity additions alone.
The earnings headline needs a second look
Amazon's quarter included $53.4 billion of non-operating pre-tax other income, primarily linked to Anthropic investments. Alphabet recorded $99.0 billion of gains on equity securities. Those marks can lift reported profits without representing cash earned from customers. Amazon 10-Q · Alphabet investment-gain reconciliation
The underlying operations still improved: quarterly operating income rose 43% at Amazon and 30% at Alphabet. But extrapolating the jump in bottom-line profit would mix operating progress with investment revaluations. This is why the valuation chart labels its denominator estimated adjusted earnings. Analyst adjustments also differ; adjusted P/E is a reference point, not a substitute for reviewing the accounts.
The cash bill changes the comparison
Over the twelve months to June 30, Amazon generated $161.4 billion of operating cash flow and spent $169.0 billion on property and equipment, net of sales and incentives. Its reported free cash flow was negative $7.6 billion. Alphabet generated $185.7 billion, spent $132.4 billion on property and equipment, and retained $53.3 billion by its reported FCF measure.

That gives Alphabet a stronger trailing cash position on these measures. It does not mean its AI buildout is painless. Its latest quarter alone produced negative $5.9 billion of free cash flow. It also raised $49.6 billion net through common and mandatory convertible preferred stock in June, and made no common-share repurchases in the first half. The financing belongs in the dilution discussion; it is not operating cash generation. Alphabet 10-Q: capital resources and share repurchases
Neither FCF definition captures every acquisition, financing or lease obligation. The important distinction is between cash generated by the business and cash supplied by investors. A positive trailing total can coexist with a deteriorating recent quarter.
The charts show the same broad setup
Both stocks finished below their 50-day and 100-day averages, but above their 200-day averages. Reading them as opposite trends would reverse the actual relationships.
Amazon's 50-day stood at 256.54, its 100-day at 253.22, and its 200-day at 241.36. September 21 was its last close above the 50-day; each of the following nine sessions remained above the contemporaneous 200-day. Friday's close was about 2.0% below the 50-day and 4.2% above the 200-day.
Alphabet's corresponding levels were 341.77, 352.71 and 337.39. Its 50-day and 200-day were 4.39 points apart using unrounded calculations, approximately 1.3%. Price sat between them, only about 0.9% above the 200-day.
The supplied volume profiles place both closes inside their heavily traded bands: 246–252 for Amazon and 336–344 for Alphabet. That describes trading concentration within the displayed window, not guaranteed support or a breakout. In both charts, the blue horizontal line is the current 50-day level, not its historical path. The gold line traces the 200-day history. Price, volume and volume profile occupy separate panels.

What would change the comparison?
For Amazon, watch whether operating cash generation catches up with capital spending while AWS sustains its growth and margin. For Alphabet, watch whether rapid cloud growth converts into renewed quarterly free cash flow, and how financing changes the earnings claim belonging to each share. For both, separate customer-driven profits from investment marks.
Alphabet currently combines the lower forecast multiple with faster cloud growth and stronger trailing FCF. Amazon offers the larger cloud business and the possibility that today's spending precedes a better cash harvest. The modest valuation gap does not settle which path will work. It makes the next cash-flow results more important than a slogan about either stock being cheap.
