TL;DR
After results reported on Oct. 28, Microsoft shares rose about 4% in after-hours trading while Alphabet’s fell about 10%. Alphabet’s Google Cloud grew faster, but it reported negative free cash flow, raised debt and sold stock; Microsoft reported positive free cash flow and beat key forecasts. Both companies said demand for AI computing exceeds available capacity.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading on Oct. 28, after the companies reported results that showed rapid growth in both cloud businesses but sharply different cash positions. Alphabet’s Google Cloud grew faster than Microsoft’s Azure, yet investors appeared to favor Microsoft’s profit and cash generation, while Alphabet reported negative free cash flow and missed several analyst forecasts.
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 revenue rose 48% to $33.2 billion, above Microsoft’s July guidance of 45%. The company said commercial remaining performance obligations, or contracted revenue not yet recognized, increased 73% to $677 billion.
Alphabet reported Google Cloud revenue of $30.7 billion, up 103%, according to its Oct. 28 release. But the source account says Alphabet’s overall revenue, earnings per share and search advertising revenue came in below analyst forecasts. It also reported negative free cash flow of $9.1 billion, its second negative quarter in a row. During the quarter, Alphabet raised $28.7 billion through bond issuance and $12.4 billion by selling new shares, and did not buy back shares.
Microsoft reported $18.6 billion in free cash flow. Its capital spending was $45.2 billion when finance leases are included, and $39.4 billion in cash payments for property and equipment—up from $19.4 billion a year earlier. Chief Financial Officer Amy Hood said some expected third-party capacity deliveries were delayed, contributing to lower spending than analysts had expected. Hood said Microsoft expected capital spending above $50 billion in the current quarter and faster investment in the first half of 2027.
Infographic 01 · The scorecard
Same night, opposite verdicts.

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 Bet
The results show why cloud growth alone did not determine the market reaction. Alphabet’s cloud business expanded faster, but its spending exceeded the cash it generated during the quarter. Microsoft, by contrast, remained cash-flow positive after substantial investment. That difference can affect how much each company must rely on borrowing or issuing shares to keep building data centers and buying computing equipment.
The share-price moves are a snapshot of investor reaction, not proof that one company will ultimately win the AI market. Both firms face substantial costs and have large contracted customer commitments. Microsoft’s $677 billion in remaining performance obligations and Google Cloud’s $561 billion indicate future contracted business, but backlogs are not the same as current cash: revenue is recognized over time, and the contracts must be served using available capacity.
The spending comparison also needs care. Microsoft’s reported capital expenditure depends on whether finance leases are included, and delivery delays pushed some expected purchases into later periods. Alphabet’s cloud growth came alongside a reported 114% increase in capital spending in the source’s comparison. The figures describe different accounting and timing effects, so they do not by themselves settle which company is investing more efficiently.

Growth Meets Capacity Constraints
Both companies described a market in which demand for AI computing exceeds available supply. Microsoft said delayed deliveries of GPUs and other capacity were affecting its investment schedule, with some deliveries expected in the first half of 2027. Alphabet has begun renting capacity from third parties, according to the source account. Those steps show that strong demand does not translate immediately into cloud revenue when computing infrastructure is constrained.
Microsoft’s quarter was the first of its fiscal 2027, which began in July. Its reported Azure growth of 48% compares with Google Cloud’s 103%, but the businesses have different revenue bases and the growth rates do not show profitability on their own. Microsoft also disclosed $10 billion in quarterly revenue from OpenAI, including revenue-sharing payments, according to its quarterly filing; the source estimates that at roughly 11% of Microsoft’s total revenue.
Alphabet’s capital-spending plan for 2026 was listed at $195 billion to $205 billion, unchanged, while Microsoft’s was about $170 billion, down from an earlier estimate of about $175 billion. Both companies indicated that investment could rise further in 2027. The source’s comparisons of spending growth are based on cash-flow statements, with some figures attributed to outside reporting, so the precise measures should not be treated as directly interchangeable.
Delayed Spending and Future Returns
It is not yet clear how much of Microsoft’s delayed spending will land in later quarters, or how quickly the new infrastructure will produce revenue. Hood’s expectation of spending above $50 billion in the current quarter and acceleration in early 2027 is a forecast, not a completed investment. Microsoft also said it would access other funding sources when it considered them attractive, but had not tapped the bond market, according to the source account.
Alphabet’s negative free cash flow and financing activity are confirmed figures in the supplied account, but they do not establish that its AI investments will fail to earn adequate returns. The available material does not provide enough detail to compare the expected returns on each company’s projects or to isolate how much of Alphabet’s spending was tied specifically to AI. It is also unclear how long capacity shortages will persist and how they will affect each company’s ability to recognize contracted revenue.
After-hours share moves reflect trading immediately after the announcements and can change when regular trading resumes. The material identifies missed analyst expectations for Alphabet and Microsoft’s reported beats, but does not establish that those differences alone caused the full share-price gap.
Investors Watch Spending and Delivery
Investors will look to upcoming quarterly reports for evidence that the companies can convert cloud commitments into recognized revenue while meeting the costs of expansion. For Microsoft, the next markers include whether planned spending rises above $50 billion in the current quarter and whether delayed capacity arrives on schedule. For Alphabet, investors will be watching free cash flow, financing needs and whether cloud growth continues alongside its high level of capital investment.
Both companies have signaled further infrastructure spending in 2027, while current supply constraints remain. Their next results should clarify whether additional computing capacity is becoming available and whether the cash generated by their businesses is keeping pace with investment. Until then, the contrast is clear in this quarter’s reported figures, but the longer-term returns on both companies’ AI spending remain unsettled.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
After the results, Microsoft shares rose about 4% in after-hours trading and Alphabet’s fell about 10%. The supplied account points to Microsoft’s positive free cash flow and results above key forecasts, compared with Alphabet’s negative free cash flow and misses on revenue, earnings per share and search advertising. The market reaction does not establish a single cause.
Did Google Cloud grow faster than Azure?
Yes. Alphabet reported Google Cloud revenue up 103% to $30.7 billion, while Microsoft reported Azure revenue up 48% to $33.2 billion. Those growth rates do not by themselves show which business is more profitable.
How did free cash flow differ?
Microsoft reported $18.6 billion in free cash flow for the quarter. Alphabet reported negative free cash flow of $9.1 billion, its second negative quarter in a row, according to the source account.
Are AI computing shortages still affecting the companies?
Both companies said demand exceeds available capacity. Microsoft cited delayed third-party deliveries, with some capacity expected in the first half of 2027; Alphabet has started renting capacity from third parties, according to the supplied material.
Does this quarter show which company will lead the AI market?
No. The results show different growth rates, cash positions and financing choices, but do not establish which company will earn the strongest long-term returns from AI. Capacity constraints and the timing of future spending remain unresolved.
