TL;DR
Microsoft shares gained about 4% in after-hours trading on Oct. 28, while Alphabet shares fell about 10%, after the companies reported quarterly results. Alphabet’s Google Cloud grew faster than Azure, but Alphabet reported negative free cash flow, missed analyst forecasts for revenue and earnings, and financed investment with new bonds and stock. The contrast points to investor concern about how quickly AI spending can be supported by cash from operations.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading on Oct. 28, after the two companies reported quarterly results and detailed heavy investment in AI computing. Alphabet’s Google Cloud grew faster than Microsoft’s Azure, but investors appeared to weigh that growth against Alphabet’s negative free cash flow and missed forecasts for revenue and earnings.
Microsoft reported revenue of $92.3 billion, up 19% from a year earlier, and adjusted earnings per share of $4.89. That topped the $4.73 analysts polled by LSEG had expected, according to CNBC. Azure revenue increased 48% to $33.2 billion, above Microsoft’s July forecast of 45%. The company disclosed Azure’s quarterly revenue in dollars for the first time in this report.
Alphabet reported Google Cloud revenue of $30.7 billion, up 103% year over year. Yet the company missed analyst expectations for revenue, earnings per share and search advertising, according to the source material’s account of CNBC’s reporting. It was Alphabet’s first miss on both revenue and profit in nearly four years, CNBC reported. The results show that fast cloud growth did not, by itself, determine the market reaction.
The cash figures diverged. Microsoft had $18.6 billion in free cash flow after investment, while Alphabet reported negative $9.1 billion for a second consecutive quarter. Alphabet raised $28.7 billion through bonds and $12.4 billion by issuing shares during the quarter, and did not buy back shares. Those figures describe financing and cash generation; they do not establish whether either company’s AI investments will earn a return.
Both companies described constraints on computing capacity as demand exceeds available supply. Microsoft said some expected third-party capacity deliveries were delayed, pushing spending into later periods. Alphabet has begun renting capacity from third parties, according to the source material. The companies also reported large contracted-revenue backlogs: $677 billion at Microsoft and $561 billion at Google Cloud. Those commitments are not cash already received; Microsoft said about 30% of its commercial remaining performance obligation is expected to become revenue within 12 months.

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 Spending Debate
The results put a practical measure of AI expansion in focus: not only how quickly cloud revenue is growing, but how the infrastructure is being funded. Data centers, chips and related equipment require substantial spending before all the capacity can generate revenue. Microsoft’s positive free cash flow offered investors evidence that it could fund investment while retaining cash in the reported quarter. Alphabet’s negative figure and new borrowing and share issuance underscored a greater near-term reliance on outside financing.
That contrast is a market reaction, not proof that one company’s AI strategy will succeed and the other’s will fail. Alphabet’s cloud growth was substantially faster, while Microsoft’s Azure revenue was larger in dollars in these reported figures. Backlogs indicate contracted demand, but they do not show when all revenue will arrive, how much profit it will produce, or whether capacity will be delivered on schedule. The financial question for both companies is whether investment and demand can translate into durable cash generation.
The reaction also highlights that cloud growth sits alongside established businesses. Alphabet’s search advertising and overall results missed forecasts, while Microsoft’s reported weakness included a 27% decline in Windows revenue from PC makers, attributed in the source material to weaker PC demand and a tough comparison. Investors may be judging AI spending alongside the health of the businesses that help pay for it.

The companies reported after the U.S. market closed on Oct. 28, making the share moves a same-evening comparison of their earnings and spending plans. Microsoft’s quarter was the first of its fiscal 2027, which began in July. Its Azure growth exceeded the forecast it had given in July, while Alphabet’s cloud division posted the faster growth rate.
Capital spending figures require care because the companies report investment in different ways. Microsoft reported $45.2 billion including finance leases, which account for long-term leased data-center capacity, and $39.4 billion in cash paid for property and equipment. The latter was twice the $19.4 billion from a year earlier. Microsoft’s cash spending was below analysts’ $50.7 billion estimate cited by CNBC, but the source material ties that gap partly to delayed deliveries—not necessarily to a decision to reduce planned investment.
The supplied scorecard puts Microsoft’s 2026 capital spending plan at about $170 billion, compared with about $175 billion indicated in July. Alphabet’s 2026 plan was listed at $195 billion to $205 billion, unchanged, with both companies pointing to higher investment in 2027. The source material says Alphabet’s capital spending rose 114% year over year and Microsoft’s cash capital spending rose 30%; the latter figure was attributed to CNBC. These measures have different scopes and should not be treated as directly interchangeable.
Microsoft Chief Financial Officer Amy Hood said delayed deliveries were one reason spending came in below expectations. Microsoft’s commercial remaining performance obligation rose 73% to $677 billion, but the company said only about 30% is expected to convert to revenue in the next 12 months. Its filing also reported $10.0 billion in quarterly revenue from OpenAI, including revenue-sharing payments; the source author calculated that as roughly 11% of total revenue. That customer concentration figure is the author’s calculation, not a company-stated share.
Delivery Timing and Returns Remain Open
When delayed capacity will arrive is not fully clear. Hood said some deliveries expected in Microsoft’s first fiscal quarter were delayed, and the company expects capital spending above $50 billion in its current quarter, with an acceleration in the first half of 2027. Those are management expectations; the source material does not give a final delivery schedule for each delayed project.
It is also too early to infer from these quarterly results whether the companies’ AI investments will generate returns proportionate to their costs. Backlogs are contracted commitments, but the timing of conversion, customer usage and eventual margins can vary. The supplied material does not provide a direct, comparable measure of the profitability of AI workloads at either company.
Alphabet’s reported negative free cash flow and financing activity are confirmed in the source material, but their future scale is unknown. The source does not detail the terms of the bond issuance or share sale, or how much additional financing Alphabet may seek. Nor does the after-hours share movement establish how investors will value the results once regular trading resumes.
Next Quarter Tests Spending Plans
Investors will look to the companies’ next earnings reports for evidence that planned infrastructure spending is turning into usable capacity and revenue. For Microsoft, near-term markers include whether the delayed deliveries arrive, whether capital spending exceeds $50 billion in the current quarter as Hood expects, and whether the company remains free-cash-flow positive through the fiscal year.
For Alphabet, the next reports can show whether Google Cloud’s rapid growth continues and whether cash generation improves as investment proceeds. Investors will also be able to track whether the company continues to use borrowing or share issuance to fund spending, and whether search advertising returns to growth consistent with expectations.
Across both companies, the reported backlog figures and ongoing supply constraints will remain important, but neither alone resolves the central question: how much of the committed demand becomes revenue and cash, and on what timeline. The next results will provide updated figures; the longer-term financial returns from AI infrastructure remain unconfirmed.
Key Questions
The source material reports that Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading. Microsoft beat analyst forecasts for revenue and earnings and reported positive free cash flow; Alphabet missed forecasts for revenue, earnings and search advertising and reported negative free cash flow. Those factors offer a possible explanation for the contrast, but the share moves do not prove a single cause.
Did Google Cloud grow faster than Azure?
Yes, by the reported year-over-year growth rates. Google Cloud revenue rose 103% to $30.7 billion, while Azure revenue rose 48% to $33.2 billion. The figures show faster percentage growth at Google Cloud, while Azure reported higher quarterly revenue in dollars.
What does negative free cash flow mean in Alphabet’s report?
Alphabet reported that cash flow after investment was negative $9.1 billion for the quarter, its second consecutive negative quarter according to the source. The figure indicates that spending exceeded cash generated under the reported measure during that period; it does not, on its own, determine the long-term results of the company’s investments.
Are Microsoft’s and Google Cloud’s backlogs cash already received?
No. The reported $677 billion Microsoft backlog and $561 billion Google Cloud backlog represent contracted or committed revenue, not cash already collected. Microsoft said about 30% of its commercial remaining performance obligation is expected to become revenue within 12 months.
What should readers watch in the next reports?
Key indicators include whether delayed data-center capacity is delivered, how capital spending compares with company expectations, whether cloud growth continues and whether free cash flow improves. The reports may clarify these near-term measures, but they will not by themselves establish the eventual returns on AI investment.
