TL;DR
Microsoft shares gained about 4% in after-hours trading after its October 28 results, while Alphabet shares fell about 10%. Alphabet’s Google Cloud grew faster than Azure, but investors also confronted negative free cash flow, an earnings miss and heavy AI-related spending.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading on October 28, after the companies reported results that put their competing AI investments in focus. Alphabet’s Google Cloud grew faster than Microsoft’s Azure, but Alphabet also reported negative free cash flow and missed analyst expectations for revenue, earnings per share and search advertising, according to the supplied report.
Microsoft reported revenue of $92.3 billion, up 19%, and adjusted earnings per share of $4.89, above the $4.73 forecast from analysts polled by LSEG, CNBC reported. Azure revenue rose 48% to $33.2 billion, exceeding Microsoft’s July forecast of 45%. The company also beat on revenue and profit overall, according to the source material.
Alphabet’s Google Cloud revenue climbed 103% to $30.7 billion, compared with Azure’s 48% growth. But Alphabet’s free cash flow was negative $9.1 billion, its second consecutive negative quarter, while Microsoft reported $18.6 billion in positive free cash flow after investments. Alphabet raised $28.7 billion through bonds and $12.4 billion by issuing shares during the quarter, and bought back no shares, according to the source.
The companies reported different spending and capacity pressures. Microsoft’s cash spending on property and equipment was $39.4 billion, twice its year-earlier level, while total capital spending including finance leases was $45.2 billion. The source says spending was below analyst expectations partly because some third-party capacity deliveries were delayed. Alphabet’s capital expenditure rose 114% year over year, according to the source’s calculations from cash-flow statements.
Infographic 01 · The scorecard
Same night, opposite verdicts.
The four numbers from my 28 October preview, scored with both companies’ own reports for July to September 2026.
The four numbers I said to watch, scored
Status chips: ok = healthy, hold = watch, urgent = warning sign. My assessment.
| Metric | Microsoft | Alphabet |
|---|---|---|
| 1 · Capex guidance | Microsoft hold About $170B for calendar 2026 (July: about $175B), lower only because deliveries slipped. More than $50B next quarter. | Alphabet hold $195–205B for 2026, unchanged. 2027 to “increase significantly”; no number yet. |
| 2 · Cloud growth vs. capex | Microsoft hold Azure +48%. Capex incl. finance leases +30%; cash capex about 2×. | Alphabet hold Google Cloud +103%. Capex +114% to $51.4B. |
| 3 · Free cash flow + funding | Microsoft ok +$18.6B (−27%). No new bonds. $10.2B returned to shareholders. | Alphabet urgent −$9.1B. $28.7B bonds and $12.4B new shares in the quarter. No buybacks. |
| 4 · Capacity | Microsoft hold “Demand continues to exceed available supply.” Delayed GPU capacity moves to the first half of 2027. | Alphabet hold “Supply constrained.” Renting third-party capacity; margin pressure ahead. |

Cash Flow Shapes the AI Trade
The contrasting share moves show that investors are weighing how AI expansion is funded, not just how quickly cloud revenue is growing. Alphabet’s cloud growth outpaced Azure’s, but its negative free cash flow and need for outside financing added a near-term funding concern. Microsoft, by contrast, remained free-cash-flow positive after investment in the reported quarter.
That distinction does not establish which company will earn more from AI over time. It does affect how investors may assess the companies’ ability to keep building data centers, buying chips and meeting customer commitments. Spending plans are not the same as cash already spent, and customer backlogs are contracts or commitments rather than immediate revenue. Microsoft reported commercial remaining performance obligations of $677 billion; only about 30% is expected to become revenue within 12 months, the source says.
The figures also point to execution risk on both sides. Microsoft’s delayed equipment deliveries pushed some expected spending into later periods, while Alphabet reportedly rented capacity from third parties. Both companies said demand exceeded available supply. If constraints persist, customers may wait longer for computing capacity even as the firms’ investment bills continue to grow.

Cloud Growth and Spending Plans
The results were released after the U.S. market closed on October 28. Microsoft’s quarter was the first of its fiscal 2027, which began in July. The source reports that Alphabet missed analyst forecasts for revenue, earnings per share and search advertising, describing it as the company’s first miss on both revenue and profit in nearly four years, citing CNBC. Microsoft, in contrast, beat on revenue and profit as well as its Azure growth forecast.
Both companies are planning substantial investment. Microsoft’s stated 2026 capital spending plan was about $170 billion, down from an earlier estimate of about $175 billion in July; Alphabet’s 2026 plan was $195 billion to $205 billion, unchanged, according to the supplied scorecard. Both indicated spending would rise further in 2027. These are plans, not completed expenditures, and the source does not provide a like-for-like accounting definition for every figure.
Microsoft’s chief financial officer, Amy Hood, said on the earnings call that some expected third-party capacity deliveries had been delayed. The source also reports that roughly three-quarters of Microsoft’s capital spending went to short-lived assets, including GPUs and CPUs. Alphabet’s results and call, as summarized in the source, described constrained supply and the use of rented capacity.
Timing of Spending and Returns
The results do not settle whether either company’s AI investment will generate returns sufficient to cover its costs. Cloud growth and customer commitments are not proof of future profit, and the source provides no forecast of when the companies’ current investments will pay back. The timing of delayed Microsoft equipment deliveries and the pace of Alphabet’s capacity rentals also remain unclear.
The after-hours share moves are an initial market reaction, not a complete measure of investor views. The supplied material does not specify the exact trading period used for each percentage or provide subsequent regular-session performance. It also does not include a full breakdown of Alphabet’s operating cash flows or detail how its new bond and share proceeds will be allocated.
Some figures in the source are described as calculations from company filings rather than company-reported comparisons. Its capex growth rates should be read with that caveat, particularly where companies use different definitions of capital spending. The underlying results are confirmed in the source as company releases, filings and earnings calls dated October 28; interpretations about why investors favored one stock remain analysis rather than a stated company explanation.
Investors Watch Capacity Delivery
Investors will look for evidence that planned spending converts into usable computing capacity and revenue. Microsoft said it expected capital spending to exceed $50 billion in the current quarter and accelerate in the first half of 2027, according to the source. It also said demand continued to exceed supply, with some GPU deliveries delayed into the first half of 2027.
For Alphabet, the next points to watch include whether Google Cloud can sustain its reported growth, how its investment affects cash generation, and whether rented capacity eases supply constraints. The source says Alphabet’s 2026 spending outlook was unchanged and that the company signaled a substantial increase in 2027, but gives no later update on the timing or financing of those expenditures.
Further quarterly filings and earnings calls should clarify actual capital spending, free cash flow and the pace at which contracted cloud commitments become recognized revenue. Until then, the market’s contrasting response reflects the quarter’s different cash-flow and forecast signals, not a settled verdict on which company will lead the AI business.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
The source reports that Microsoft rose about 4% after hours while Alphabet fell about 10%. Microsoft beat analyst expectations on revenue and profit and reported positive free cash flow. Alphabet’s Google Cloud grew faster, but the company reported negative free cash flow and missed expectations for revenue, earnings per share and search advertising. The source’s explanation of the market reaction is analysis, not a stated explanation from every investor.
Did Google Cloud grow faster than Azure?
Yes. The source reports Google Cloud revenue growth of 103% to $30.7 billion and Azure growth of 48% to $33.2 billion. The figures cover the companies’ reported quarters and are presented in the source as year-over-year growth.
How did the companies’ free cash flow compare?
Microsoft reported $18.6 billion in positive free cash flow after investments, while Alphabet reported negative $9.1 billion, its second negative quarter in a row, according to the source material.
What remains uncertain about the AI spending?
The timing of delayed equipment deliveries, the duration of supply constraints and the returns on the companies’ investment remain unclear. Customer commitments and backlogs do not by themselves show when revenue will be recognized or whether it will cover the cost of expansion.
