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 constrained AI capacity, but Microsoft generated $18.6 billion in free cash flow while Alphabet recorded a $9.1 billion outflow and missed analyst forecasts.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading on October 28, after both companies reported results showing fast cloud growth but different financial pressures from their AI investments. Alphabet’s Google Cloud grew faster than Microsoft’s Azure, but Alphabet also reported negative free cash flow and missed analyst forecasts for revenue, earnings per share and search advertising, while Microsoft beat forecasts and generated positive free cash flow.
Microsoft reported revenue of $92.3 billion, up 19% from a year earlier, and adjusted earnings per share of $4.89. Analysts polled by LSEG had expected $4.73 per share, according to CNBC. Azure revenue increased 48% to $33.2 billion, beating the 45% growth rate Microsoft had forecast in July. The company disclosed Azure’s quarterly revenue in dollars for the first time.
Alphabet reported Google Cloud revenue of $30.7 billion, up 103% year over year. But its overall results disappointed analyst expectations for revenue, earnings per share and search advertising, according to CNBC. The source report described this as Alphabet’s first miss on both revenue and profit in nearly four years. It also reported free cash flow of minus $9.1 billion, the company’s second consecutive negative quarter.
The investment figures show why the results prompted different reactions. Microsoft reported $18.6 billion in free cash flow after investment, while Alphabet’s cash outflow coincided with raising $28.7 billion in bonds and $12.4 billion through new shares during the quarter. The source report said Alphabet bought back no shares. Those figures do not establish that investors rejected Alphabet’s AI strategy; they show that its spending and financing needs were a concern alongside its earnings miss.
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 Divides the AI Bets
The results put a sharper focus on how AI expansion is financed, not just how quickly cloud revenue grows. Microsoft’s Azure grew more slowly than Google Cloud, but Microsoft’s reported cash generation gave investors evidence that it could fund large investments while remaining cash-flow positive. Alphabet’s faster cloud growth came with a negative free-cash-flow result and new borrowing and share issuance, increasing attention to the cost of scaling its infrastructure.
That distinction matters to shareholders because major AI data-center investments require substantial cash before the resulting services produce recognized revenue. A large backlog can indicate customer commitments, but it is not the same as cash already received. The source report puts Microsoft’s commercial remaining performance obligations at $677 billion and Google Cloud’s customer commitments at $561 billion; it also notes that a portion of Microsoft’s backlog is expected to convert to revenue only over time.
The market reaction is a short-term reading of risk, not a verdict on which company will ultimately lead AI. Both companies say demand exceeds available computing capacity. Their ability to turn that demand into delivered services, revenue and sustainable cash flow remains central to the investment case.

Cloud Growth Meets Capacity Limits
The results were released after the U.S. market closed on October 28. The source analysis compares the companies across investment plans, cloud growth relative to capital spending, free cash flow and computing capacity. It reports that neither company raised its 2026 capital-spending plan in these results, while both pointed to higher spending in 2027.
Microsoft’s reported capital spending depends on the measure used. Including finance leases, it was $45.2 billion; cash paid for property and equipment was $39.4 billion, compared with $19.4 billion a year earlier. Microsoft’s chief financial officer, Amy Hood, said some third-party capacity deliveries expected in the quarter were delayed. She said the company expected capital spending above $50 billion in the current quarter, with an acceleration in the first half of 2027. The source report lists Microsoft’s 2026 capital-spending plan at about $170 billion, compared with about $175 billion in July.
The source report lists Alphabet’s 2026 capital-spending plan at $195 billion to $205 billion, unchanged, with a large increase expected in 2027. It says Microsoft’s contracted commercial backlog rose 73% to $677 billion, while Alphabet’s Google Cloud commitments were $561 billion. Those commitments indicate future demand, but not the timing or cash value of every contract. The report also says Microsoft generated $10 billion in quarterly revenue from OpenAI, including revenue-sharing payments, based on its quarterly filing.
Costs and Delivery Timing Remain Open
The results do not establish whether either company can convert its investment and customer commitments into returns at the pace markets expect. Delivery constraints remain a live issue: the source report says Microsoft’s delayed GPU deliveries could slip into the first half of 2027 and that Alphabet has begun renting capacity from third parties. The scale, duration and cost of those constraints are not fully specified in the supplied material.
It is also unclear how much of the reported backlog will become revenue, and when. Microsoft disclosed that only about 30% of its $677 billion commercial remaining performance obligation was expected to turn into revenue within 12 months; the source report gives no equivalent conversion schedule for Google Cloud’s $561 billion in commitments. The after-hours share moves may change as investors receive more information, and they do not by themselves show how the companies’ longer-term AI strategies will perform.
Watch Spending and Capacity Updates
The next indicators will be capital spending, free cash flow and infrastructure delivery in upcoming quarterly reports. Microsoft said it expected capital spending above $50 billion in the current quarter and faster investment in the first half of 2027. Investors will be able to compare those plans with actual spending and whether delayed capacity arrives on schedule.
For Alphabet, upcoming results will show whether cloud growth can continue alongside the elevated investment program and whether free cash flow returns to positive territory. Both companies’ ability to expand usable computing capacity—and convert commitments into delivered services and recognized revenue—will help clarify whether strong demand can support the cost of their AI build-outs.
Key Questions
The source report points to different earnings and cash-flow results. Microsoft beat analyst expectations and reported $18.6 billion in free cash flow. Alphabet missed expectations and reported negative free cash flow of $9.1 billion. These factors accompanied after-hours gains for Microsoft and a decline for Alphabet; the share moves do not prove a single cause.
Did Google Cloud grow faster than Azure?
Yes. Alphabet reported Google Cloud growth of 103% to $30.7 billion, while Microsoft reported Azure growth of 48% to $33.2 billion. The companies’ cloud businesses differ in size and scope, so the growth rates alone do not compare their full financial performance.
What does negative free cash flow mean for Alphabet?
It means Alphabet’s cash outflow exceeded its cash inflow under the free-cash-flow measure for the quarter, according to the source report. Alphabet also raised $28.7 billion in bonds and $12.4 billion by issuing shares. The supplied material does not establish how its cash position or free cash flow will develop in later quarters.
Are AI computing capacity limits affecting both companies?
Both companies said demand exceeded available capacity, according to the source report. Microsoft cited delayed third-party capacity deliveries, while Alphabet had started renting capacity from third parties. The scale and duration of the supply constraints remain unclear.
