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 heavy AI investment, but Microsoft beat key forecasts and generated $18.6 billion in free cash flow, while Alphabet reported a $9.1 billion outflow and missed analyst expectations on revenue, earnings per share and search advertising.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading on Wednesday, October 28, as investors assessed quarterly results from two major AI spenders. The contrast came despite faster cloud growth at Google Cloud: investors appeared to reward Microsoft’s earnings beat and positive free cash flow, while weighing Alphabet’s forecast misses and negative free cash flow.
Microsoft reported revenue of $92.3 billion, up 19%, and adjusted earnings per share of $4.89. Analysts surveyed by LSEG had expected $4.73 per share, according to CNBC. Azure revenue increased 48% to $33.2 billion, ahead of the 45% growth rate Microsoft had guided in July. It was the first time Microsoft disclosed Azure quarterly revenue in dollars.
Alphabet’s Google Cloud revenue rose 103% to $30.7 billion, more than twice Azure’s growth rate. But the source report says Alphabet fell short of analyst expectations for revenue, earnings per share and search advertising. It described this as the company’s first miss on both revenue and profit in nearly four years, citing CNBC. The reported figures show that faster cloud growth alone did not settle investors’ assessment of the quarter.
The companies’ cash positions diverged. Microsoft recorded $18.6 billion in free cash flow, while Alphabet’s was negative $9.1 billion, its second consecutive negative quarter, according to the source report. Alphabet raised $28.7 billion through bonds and $12.4 billion by issuing shares during the quarter, and did not repurchase shares. Microsoft had not tapped the bond market, though Chief Financial Officer Amy Hood said the company would consider other funding sources if attractive.
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. |

The market response highlights a question investors are asking about the AI buildout: how much growth can companies fund from cash they generate, rather than from borrowing or issuing shares? Rapid revenue growth can support large infrastructure plans, but those plans also carry costs before all contracted customer commitments turn into recognized revenue or cash receipts.
The figures do not establish which company will ultimately earn more from AI or whether either spending plan will pay off. They do show why investors may distinguish between two companies with strong cloud demand. Microsoft reported positive free cash flow alongside its results beat. Alphabet paired faster Google Cloud growth with a cash outflow, new borrowing and share issuance, as well as misses in other reported measures. That combination may lead investors to scrutinize the pace and financing of its investment more closely.
Both businesses also face a capacity constraint. Microsoft said some expected equipment deliveries were delayed, while Alphabet was renting capacity from third parties, according to the source report. If hardware remains scarce, customer demand and large backlogs may not translate into revenue as quickly as investors expect.

Two Cloud Businesses, Different Results
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. The source report says the cash figure was below the $50.7 billion analysts expected, citing StreetAccount via CNBC. Hood attributed the shortfall to delayed third-party capacity deliveries, not a stated decision to abandon planned investment.
Hood said Microsoft expected capital spending above $50 billion in the current quarter and an acceleration in the first half of 2027. The company’s commercial remaining performance obligations, a measure of contracted revenue not yet recognized, rose 73% to $677 billion. About 30% is expected to be recognized as revenue within 12 months, and the average duration is 2.3 years, according to the source report. Those commitments indicate demand, but they are not the same as cash already received.
The report puts Alphabet’s 2026 capital spending outlook at $195 billion to $205 billion, unchanged, with a larger increase expected in 2027. It lists Microsoft’s 2026 plan at about $170 billion, down from roughly $175 billion in July, also with higher spending expected in 2027. The source’s comparison of spending growth draws on cash flow statements and, for Microsoft’s 30% figure, CNBC reporting; the measures should not be treated as identical without accounting for how each company reports investment.
Spending and Capacity Still May Shift
The share moves reflect after-hours trading and do not establish how investors will value either company over a longer period. The source material gives no subsequent regular-session price performance. It also remains unclear how quickly the companies can add computing capacity, how much delayed equipment will affect future spending, and when contracted cloud commitments will convert into recognized revenue and cash.
The reported cash-flow contrast is a snapshot of one quarter, not proof that Alphabet’s investment cannot be funded or that Microsoft’s spending will remain self-financed. Alphabet’s bond and share issuance show that it raised outside capital in the period, but the source does not detail the future cost or timing of all planned investment. Microsoft’s delayed deliveries may also mean that some spending has shifted to later quarters rather than disappeared.
One other risk flagged in the source is customer concentration: Microsoft reported $10 billion of revenue from OpenAI during the quarter, including revenue-sharing payments. That was roughly 11% of Microsoft’s total revenue by the source author’s calculation. The available material does not establish how that relationship or other customers’ commitments may change.
Upcoming Quarters Will Test the Plans
Investors will next look for evidence that both companies can turn heavy AI infrastructure spending into revenue and cash flow. For Microsoft, Hood’s forecast of more than $50 billion in capital spending in the current quarter and higher investment in the first half of 2027 sets a near-term benchmark. The company’s results will also show whether delayed capacity arrives and whether demand continues to exceed supply.
For Alphabet, upcoming results will clarify whether its cash outflow persists as its capital expenditure plan advances, and whether growth in Google Cloud is accompanied by improvement in the company’s other reported businesses. Its use of bonds and share issuance will remain part of the financing picture described in the source report. Neither company’s current backlog alone answers how profitable its AI investments will be.
The next earnings reports and management updates should provide more detail on spending, capacity and the conversion of customer commitments into revenue. Until then, the October results offer a contrast in quarterly performance and funding, not a definitive verdict on which company will win the AI market.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
After the October 28 results, Microsoft rose about 4% in after-hours trading and Alphabet fell about 10%. Microsoft beat analyst expectations for revenue and adjusted earnings per share and reported positive free cash flow. Alphabet missed analyst expectations for revenue, earnings per share and search advertising, while reporting negative free cash flow, according to the source material.
Did Google Cloud grow faster than Azure?
Yes. Google Cloud revenue grew 103% to $30.7 billion, while Azure revenue grew 48% to $33.2 billion. Those figures describe revenue growth, not profit or cash flow.
How did their free cash flow compare?
Microsoft reported $18.6 billion in free cash flow. Alphabet reported negative $9.1 billion, its second negative quarter in a row, according to the source report.
Does the market reaction prove Microsoft’s AI investments will pay off?
No. The after-hours share moves show investors’ immediate response to the reported results; they do not establish the eventual returns on either company’s AI spending. Both companies said demand exceeded available capacity, and future revenue, costs and cash flow remain to be seen.
