TL;DR
Microsoft shares rose about 4% in after-hours trading after its October 28 results, while Alphabet shares fell about 10%. Alphabet’s Google Cloud grew faster, but investors also faced weaker-than-expected results and negative free cash flow amid heavy investment; Microsoft reported positive free cash flow and beat key forecasts. Both companies said demand for computing capacity exceeds supply.
Both companies reported strong cloud growth, but at sharply different rates. Microsoft said Azure revenue increased 48% to $33.2 billion, its first quarterly disclosure of Azure revenue in dollars. Alphabet reported Google Cloud revenue rose 103% to $30.7 billion. Those figures alone did not determine the market reaction: Alphabet also missed analyst expectations for revenue, earnings per share and search advertising, while Microsoft beat expectations on revenue and profit and Azure growth exceeded its prior forecast.
The cash figures sharpened the contrast. Microsoft reported $18.6 billion in free cash flow after investment; Alphabet reported negative $9.1 billion, its second consecutive negative quarter, according to the source material. Alphabet raised $28.7 billion through bonds and $12.4 billion by issuing shares during the quarter, and did not buy back shares. Microsoft did not issue new bonds in the quarter, though its finance chief said the company could use additional funding sources if attractive.
Spending remains substantial at both companies. Microsoft reported $39.4 billion in cash spending on property and equipment, twice the year-earlier amount, and $45.2 billion including finance leases. Alphabet’s 2026 capital spending plan remains $195 billion to $205 billion. Microsoft’s 2026 plan was about $170 billion, down from an earlier estimate of about $175 billion, while executives pointed to faster investment growth in 2027. These are company plans and reported costs, not guarantees of future returns.
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 AI Investment Risk
The market reaction suggests investors are weighing whether AI expansion can be funded from ongoing operations, as well as whether cloud sales are growing. Cloud growth is not the same as cash generation: data centers, chips and related infrastructure require large upfront outlays, while contracted customer revenue may be recognized over time. The source’s analysis argues that self-funded growth appeared less risky to investors than growth paired with negative free cash flow and weaker results in an established business.
That interpretation is not proof that Microsoft’s AI investments will earn more, or that Alphabet’s spending will fail. Both companies say demand for computing capacity exceeds supply, and both have large customer commitments. But those commitments are not cash already received. Investors will be watching whether the infrastructure spending converts into revenue and cash flow, and how much outside funding each business needs as projects proceed.

Cloud Growth Meets Capacity Limits
The results were reported on the same evening, making the comparison unusually direct. Microsoft’s quarter was its first of fiscal 2027; the company said revenue rose 19% to $92.3 billion and adjusted earnings per share were $4.89, above the $4.73 expected by analysts polled by LSEG, according to CNBC. Azure growth of 48% was higher than the 45% Microsoft had forecast in July.
Microsoft’s reported capital spending depends on the measure used: the $45.2 billion figure includes finance leases, while $39.4 billion is cash paid for property and equipment. Chief Financial Officer Amy Hood said some expected third-party capacity deliveries were delayed. She expected capital spending above $50 billion in the current quarter and faster investment in the first half of 2027. The company’s commercial remaining performance obligation, or contracted revenue not yet recognized, rose 73% to $677 billion; about 30% is expected to become revenue within 12 months, according to the source material.
Alphabet’s cloud backlog was reported at $561 billion. The source also says Alphabet’s capital spending rose 114% year over year, based on its cash-flow statements, while Google Cloud revenue rose 103%. That comparison is relevant to the spending question but does not establish how quickly the investments will produce future revenue. Both firms said supply constraints are affecting their ability to meet demand: Microsoft cited delayed GPU deliveries, while Google has begun renting capacity from third parties.
Returns and Funding Still Unsettled
The results and after-hours share moves do not settle which company will gain more from AI. Future returns on the infrastructure spending remain unknown, as do the pace at which current customer commitments will become recognized revenue and cash receipts. Backlogs are contractual obligations, but their value depends on delivery and timing.
Capacity constraints also complicate comparisons. Microsoft said deliveries expected in the quarter were delayed, and its spending may rise as those deliveries arrive. Alphabet has turned to third-party capacity, but the source material does not state how long that arrangement will last or its full cost. It is also not clear whether Alphabet’s negative free cash flow will persist in coming quarters or how much additional funding it may need.
The supplied account attributes Alphabet’s share decline to the combination of missed expectations and spending-related cash concerns, but a single after-hours move cannot establish investors’ full reasoning. The precise contribution of each earnings item to the share reaction is not quantified.
Upcoming Spending and Delivery Updates
Investors will look to Microsoft’s next quarterly report for evidence that delayed capacity deliveries are arriving and for the actual level of capital spending against Hood’s forecast of more than $50 billion in the current quarter. The company has also pointed to faster investment growth in the first half of 2027, making delivery timing and cash generation key items to track.
For Alphabet, forthcoming results will show whether Google Cloud can sustain its rapid growth while the company carries a large investment program, and whether free cash flow moves back into positive territory. Updates on third-party computing capacity, financing and the conversion of cloud backlogs into revenue could clarify how the two AI investment plans are developing. Until then, the reported figures show current performance and spending, not the eventual returns on either company’s AI buildout.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
Microsoft beat revenue and profit expectations and reported $18.6 billion in free cash flow. Alphabet missed analyst expectations for revenue, earnings per share and search advertising and reported negative free cash flow of $9.1 billion. These differences coincided with opposite after-hours share moves, though the exact contribution of each factor is not known.
Did Alphabet’s cloud business grow faster than Azure?
Yes. Alphabet reported Google Cloud revenue growth of 103% to $30.7 billion, compared with Microsoft’s reported Azure growth of 48% to $33.2 billion. The reported growth rates do not by themselves measure profitability or cash generation.
What does negative free cash flow mean in this report?
Alphabet’s reported negative $9.1 billion means its free cash flow was below zero for the quarter under the measure cited by the source. The source says the company raised money through bonds and new shares during the period; the figure does not establish what its cash flow will be in future quarters.
Are the cloud backlogs the same as cash already earned?
No. The reported $677 billion Microsoft and $561 billion Google Cloud figures are customer commitments or backlog, not cash already received. Some contracted revenue is expected to be recognized over time, and the timing and realization of those commitments remain relevant.
