TL;DR
Microsoft shares rose about 4% in after-hours trading after its October 28 results, while Alphabet shares fell about 10%. Both reported rapid cloud growth and tight AI capacity, but Microsoft generated $18.6 billion in free cash flow while Alphabet reported negative $9.1 billion and missed analyst expectations for revenue, earnings and search advertising.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading on October 28, after the companies reported sharply different quarterly results. Alphabet’s Google Cloud grew faster than Microsoft’s Azure, but Microsoft beat analyst expectations and generated $18.6 billion in free cash flow, while Alphabet reported a $9.1 billion cash outflow after heavy investment.
Both companies reported strong cloud growth. Microsoft said Azure revenue rose 48% to $33.2 billion; Alphabet reported Google Cloud revenue up 103% to $30.7 billion. The growth figures do not by themselves show how efficiently each company is funding its expansion: the source analysis says Alphabet’s capital spending rose 114% from a year earlier, while Microsoft’s cash spending on property and equipment doubled to $39.4 billion.
Microsoft reported quarterly revenue of $92.3 billion, up 19%, and adjusted earnings per share of $4.89, above the $4.73 expected by analysts polled by LSEG, according to CNBC. Azure growth also topped Microsoft’s July guidance of 45%. Alphabet, by contrast, missed analyst forecasts for revenue, earnings per share and search advertising, according to the source report’s account of CNBC’s coverage.
Cash flow and financing stood out in the comparison. Alphabet’s negative $9.1 billion in free cash flow was its second negative quarter in a row, according to the source material. It also said Alphabet raised $28.7 billion in bonds and $12.4 billion by selling shares during the quarter, and did not buy back shares. Microsoft reported positive free cash flow and had not issued new bonds, although its finance chief said the company could seek other funding if it considered the terms attractive.

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 Sets the Market Apart
The share-price split suggests investors were weighing not just how quickly AI-related cloud sales are growing, but also how much cash those sales require. Alphabet’s faster cloud growth did not offset its earnings misses and negative free cash flow in the market’s immediate response. Microsoft’s results offered investors stronger reported earnings and cash generation, though that advantage should be read alongside the cost of infrastructure still to come.
Neither company’s current cash figure settles whether its AI spending will earn an adequate return over time. Both are committing large sums to data centers and computing equipment, and both say customer demand exceeds available capacity. The near-term distinction is the funding risk: when investment outpaces cash coming in, a company may rely more on borrowing or issuing shares. That can affect financial flexibility even if demand remains strong.
There is also a timing complication. Microsoft’s cash investment was lower than some analysts had expected partly because equipment deliveries were delayed. The spending has not necessarily disappeared; Microsoft expects a later increase. The quarter therefore captures both cash generation and the timing of construction and deliveries, rather than a settled measure of the long-run economics of AI infrastructure.

Cloud Growth Meets Capacity Limits
The results were reported after the U.S. market closed on October 28. Microsoft’s quarter was its first of fiscal 2027, since its fiscal year begins in July. The share moves cited here are after-hours reactions, not a final assessment of how either stock performed in the next regular session.
Microsoft reports capital investment in more than one way. Including finance leases for data-center assets, its capital spending was $45.2 billion; cash paid for property and equipment was $39.4 billion. Chief Financial Officer Amy Hood said some third-party capacity deliveries expected during the quarter were delayed. She said about three quarters of capital spending went to short-lived assets such as GPUs and CPUs, including higher memory and storage costs. Microsoft expected capital spending above $50 billion in the following quarter and an acceleration in the first half of 2027.
The companies also have large contracted workloads ahead. Microsoft’s commercial remaining performance obligation, a measure of contracted revenue not yet recognized, rose 73% to $677 billion; the source says about 30% is expected to become revenue within 12 months. Google Cloud’s customer commitments were reported at $561 billion. Such backlogs indicate contracted demand, but they are not cash already received, and they can take time to convert into recognized revenue.
Spending and Demand Still Moving
The reported figures do not establish which company will earn higher returns from AI investment over time. The size and timing of future infrastructure spending, the pace at which contracted commitments become revenue, and the eventual cost of supplying computing capacity remain uncertain. Backlogs are commitments rather than cash on hand, and their conversion depends on delivery and customer use.
Microsoft’s delayed equipment deliveries complicate comparisons of quarterly cash spending: some planned investment may be recorded later. Alphabet’s negative free cash flow and financing activity are confirmed in the supplied account, but the material does not establish that these conditions will persist or how they will affect future results. The after-hours share moves also show only the initial market reaction, not a lasting verdict.
Investors Watch the Next Spending Wave
Investors will look to the next reporting periods for evidence that cloud growth can translate into cash generation as both companies add capacity. For Microsoft, the next quarter’s spending and its expected acceleration in the first half of 2027 will help show how delayed deliveries affect the investment schedule. Alphabet’s subsequent results will show whether free cash flow recovers and whether its cloud growth continues alongside the added financing needs described in the source material.
Both companies will also need to show how quickly they can meet demand. Microsoft said some capacity deliveries had slipped, while Alphabet was renting capacity from third parties. The timing of new infrastructure, the costs attached to it and the revenue it supports remain central questions; the supplied information does not provide a later results date or a confirmed schedule for resolving the capacity constraints.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
In after-hours trading on October 28, Microsoft gained about 4% and Alphabet fell about 10%. The source account points to Microsoft’s analyst-beating results and $18.6 billion in free cash flow, compared with Alphabet’s misses on revenue, earnings and search advertising and its negative $9.1 billion in free cash flow. These factors help explain the immediate reaction but do not prove what drove every investor’s decision.
Which company’s cloud business grew faster?
Google Cloud grew faster in the reported quarter: revenue rose 103% to $30.7 billion. Microsoft’s Azure revenue rose 48% to $33.2 billion. The growth rates refer to different cloud businesses and do not alone measure profitability or investment efficiency.
What does negative free cash flow mean for Alphabet?
It means Alphabet’s cash outflows exceeded cash generated after investment under the measure cited in the source. Alphabet reported negative $9.1 billion, its second consecutive negative quarter, and raised money through bonds and share sales during the quarter. The figure does not by itself show whether that pattern will continue.
Are Microsoft and Alphabet able to meet AI computing demand?
Both described constrained capacity. Microsoft said some third-party deliveries were delayed, including GPU deliveries, while Alphabet had started renting capacity from outside providers. The source material does not give a date when either company expects supply to catch up with demand.
Do the companies’ cloud backlogs mean they already received the money?
No. Microsoft’s $677 billion commercial remaining performance obligation and Google Cloud’s reported $561 billion in customer commitments represent contracted business, not cash already collected. The commitments can take time to become recognized revenue and are not equivalent to completed sales.
