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 Alphabet reported negative free cash flow and missed analyst expectations; Microsoft beat forecasts and remained free-cash-flow positive. 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 October 28, after the two companies reported quarterly results that gave investors sharply different signals about the cost of their AI expansion. Alphabet’s Google Cloud revenue grew 103%, more than twice Azure’s 48% growth, but Alphabet reported negative $9.1 billion in free cash flow and missed analyst forecasts. Microsoft beat expectations and reported $18.6 billion in free cash flow.
The results showed strong cloud growth at both companies, alongside heavy investment in computing capacity. Microsoft reported Azure revenue of $33.2 billion, up 48% year over year. Google Cloud generated $30.7 billion in revenue, up 103%. Microsoft said its Azure growth exceeded the 45% rate it had guided in July. The cloud figures do not, by themselves, show how profitable the companies’ AI investments will be.
Cash spending helps explain investors’ contrasting reactions. Microsoft spent $39.4 billion in cash on property and equipment during the quarter, twice the $19.4 billion reported a year earlier. Including finance leases, its capital spending was $45.2 billion. Alphabet’s capital spending rose 114% year over year, according to the source’s calculations from company cash-flow statements. Microsoft’s cash flow remained positive after investment; Alphabet’s was negative for a second consecutive quarter.
Alphabet raised $28.7 billion through bond sales and $12.4 billion by issuing new shares during the quarter, and did not buy back shares. Microsoft had not issued new bonds for its spending, though its finance chief said the company could seek other funding if it found that attractive. The companies also reported large contracted-revenue backlogs: $677 billion for Microsoft and $561 billion for Google Cloud. Those commitments represent future revenue, not cash already received.
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 Spending Bet
The results put investors’ attention on whether cloud growth can support the cost of building AI infrastructure. A faster revenue growth rate is not the same as stronger cash generation: Alphabet’s Google Cloud expanded more quickly, while the company’s overall free cash flow was negative. Microsoft’s results offered investors a different combination: slower cloud growth than Google’s, but positive free cash flow and results above analyst expectations.
That distinction matters because data centers, chips and related equipment require substantial spending. If investment continues to outpace cash generated by the business, companies may need to rely more on borrowing or issuing shares. Alphabet did both during the quarter, while Microsoft said it remained free-cash-flow positive. Those facts help explain the market response, but do not establish which company will earn a better return from its AI investments over time.
Capacity is another constraint. Both companies said demand exceeds available supply. Microsoft’s delayed equipment deliveries reduced spending in the quarter, but its finance chief expects spending to rise again. Alphabet has begun renting capacity from third parties. For customers, the shortage may affect when computing resources become available; for investors, it makes planned spending and reported revenue harder to compare quarter by quarter.

Cloud Growth Meets Infrastructure Costs
The figures come from earnings released after the U.S. market closed on October 28. Microsoft’s quarter was the first of its fiscal 2027, which began in July. Its total revenue rose 19% to $92.3 billion, and adjusted earnings per share were $4.89, above the $4.73 analysts polled by LSEG had expected, according to CNBC. Alphabet missed analyst expectations for revenue, earnings per share and search advertising, according to the source, citing CNBC.
Microsoft’s spending needs careful comparison because it reports capital investment on more than one basis. The $45.2 billion figure includes finance leases, while $39.4 billion is cash paid for property and equipment. The company said some expected third-party capacity deliveries were delayed, leaving quarterly spending below the $50.7 billion analysts expected, according to StreetAccount figures cited by CNBC. The delay shifts spending timing; it does not mean the planned equipment will not be needed.
Microsoft’s contracted commercial revenue backlog rose 73% to $677 billion, but the source says only about 30% is expected to be recognized as revenue within 12 months, with an average duration of 2.3 years. Alphabet’s Google Cloud backlog was reported at $561 billion. Both totals point to contracted demand, but their timing and eventual conversion into revenue remain relevant to how investors judge the companies’ spending.
Returns and Delivery Timelines Remain Open
The results do not show whether either company’s AI spending will produce returns large enough to justify the costs. Backlog totals are commitments for future business, not cash on hand, and the timing of revenue recognition differs. The figures also do not establish how much of future cloud growth will come specifically from AI services.
Capacity constraints make the near-term outlook less certain. Microsoft said deliveries had been delayed and pointed to higher spending later; the source reports that Alphabet is renting capacity from third parties. The exact timing and scale of available computing resources are not provided. It is also unclear whether Alphabet’s negative free cash flow will persist, or whether Microsoft will need additional financing as its investment accelerates.
The after-hours share moves reflect investors’ immediate response to the results, not a settled assessment of long-term performance. The supplied source does not give the share prices after regular trading resumed, so the duration of the initial reaction cannot be confirmed here.
Upcoming Quarters Will Test Spending Plans
Investors will watch whether Microsoft’s delayed capacity arrives and whether its spending rises as Hood forecast. She said capital spending would exceed $50 billion in the current quarter and accelerate in the first half of 2027. Microsoft also said some GPU deliveries had slipped into the first half of 2027.
For Alphabet, the next results should show whether Google Cloud’s rapid growth can continue alongside the company’s high infrastructure spending, and whether free cash flow returns to positive territory. Both companies’ ability to supply customers will remain a key measure as they work through the reported capacity shortage. Their next earnings reports can provide updated figures, but the source does not give reporting dates.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
After the companies reported results on October 28, Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading. Microsoft beat analyst expectations and reported $18.6 billion in free cash flow; Alphabet missed forecasts and reported negative $9.1 billion in free cash flow. The figures help explain the different reaction but do not establish the market’s full reasoning.
Which company had faster cloud growth?
Google Cloud grew faster in the reported quarter: revenue rose 103% to $30.7 billion. Microsoft said Azure revenue increased 48% to $33.2 billion.
What does negative free cash flow mean in these results?
It means Alphabet’s cash outflows exceeded the cash generated after investment for the period reported. The source gives Alphabet’s free cash flow as negative $9.1 billion, its second negative quarter in a row. It does not, on its own, show whether the company’s AI investments will pay off over time.
Are the companies’ backlogs money they have already received?
No. Microsoft’s $677 billion commercial backlog and Google Cloud’s $561 billion backlog represent contracted revenue that has not yet been recognized. They are not equivalent to cash already collected, and the timing of future revenue can vary.
What should investors watch next?
Key developments include Microsoft’s expected increase in capital spending, the timing of delayed equipment deliveries, Alphabet’s free cash flow, and whether either company can expand capacity to meet demand. Both companies said demand exceeds available supply.
