TL;DR
Microsoft shares gained about 4% in after-hours trading while Alphabet shares fell about 10% after both companies reported results on October 28, 2026. Alphabet’s Google Cloud grew faster, but investors also confronted an earnings miss and negative free cash flow after heavy investment; Microsoft reported positive free cash flow and beat key forecasts. The reaction reflects different financial risks, not a settled verdict on which company will lead in AI.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading on October 28, after the companies reported sharply different financial results and cash-flow positions. Alphabet’s Google Cloud grew faster than Microsoft’s Azure, but Alphabet also missed analyst forecasts and reported negative free cash flow amid heavy AI investment, while Microsoft beat key expectations and remained cash-flow positive.
The headline cloud figures favored Alphabet on growth rate: Google Cloud revenue climbed 103% to $30.7 billion, while Azure revenue rose 48% to $33.2 billion. Microsoft disclosed Azure revenue in dollars for the first time in these results. Both companies said demand for AI computing capacity exceeded supply, a constraint that can delay the conversion of customer commitments into recognized revenue.
The cash figures moved the comparison in the other direction. Microsoft reported $18.6 billion in free cash flow after investment, while Alphabet recorded negative $9.1 billion, its second consecutive negative quarter, according to the source analysis of company releases and filings. Alphabet raised $28.7 billion through bonds and $12.4 billion by issuing shares during the quarter, and did not buy back shares. The source presents the cash gap as a key reason for the opposite market reaction; that is an interpretation of investor priorities, not a direct measure of every shareholder’s reasoning.
Results also differed against 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. Azure’s 48% growth exceeded the 45% rate Microsoft had guided in July. Alphabet, by contrast, missed analyst expectations for revenue, earnings per share and search advertising, according to the source, which cites CNBC. Its account says the revenue and profit misses were the first in nearly four years.

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 Trade
The contrast matters because AI infrastructure requires large, ongoing outlays for data centers, chips and related equipment, often before the resulting capacity produces revenue. Cloud growth alone does not show how comfortably a company can finance expansion. Investors may weigh whether current operations can fund the build-out, how much additional borrowing or share issuance may be needed, and when promised capacity can be delivered.
Microsoft’s positive free cash flow gave investors evidence that it could continue investing while retaining cash, although its spending is set to rise. Alphabet’s negative figure and fresh debt and equity funding made the cost of its expansion more visible. That does not establish that Alphabet’s investments will fail or that Microsoft’s will pay off. It does show why the market can reward a slower-growing cloud business when its financial position appears less strained, particularly when the faster-growing company also misses forecasts.
The supply constraint complicates both companies’ growth plans. Customers have committed large sums to cloud services, but contracted business is not the same as cash collected or revenue already earned. The source reports $677 billion in Microsoft commercial remaining performance obligations and $561 billion for Google Cloud. Those commitments point to future demand, but their timing, delivery requirements and costs matter when judging near-term performance.

Two Cloud Businesses, Different Results
The October 28 reports came as both companies were investing heavily to meet AI demand. The comparison in the source uses four measures: planned capital spending, cloud growth relative to investment, free cash flow and available computing capacity. Its central point is that neither company’s fast cloud growth removes the need to account for the cost and timing of infrastructure spending.
Microsoft’s capital spending depends on the measure used. It reported $45.2 billion including finance leases, while cash paid for property and equipment was $39.4 billion, compared with $19.4 billion a year earlier. Spending was below the $50.7 billion analysts expected, with CFO Amy Hood attributing the gap to delayed third-party capacity deliveries. Hood said roughly three-quarters of the investment went to short-lived assets such as GPUs and CPUs, including higher memory and storage costs. She expected capital spending above $50 billion in the following quarter, with acceleration in the first half of 2027.
Microsoft’s fiscal year begins in July, making this its first quarter of fiscal 2027. Its commercial remaining performance obligation rose 73% to $677 billion, but the source says about 30% is expected to become revenue within 12 months and gives an average duration of 2.3 years. Microsoft’s filing also reported $10 billion in quarterly revenue from OpenAI, including revenue-sharing payments. These details show both the scale and the concentration and timing factors behind its growth.
The source says Alphabet’s 2026 capital spending plan was unchanged at $195 billion to $205 billion, with a larger increase indicated for 2027. It also reports that Google Cloud’s growth came alongside a 114% rise in capital spending, calculated from cash-flow statements. Alphabet was renting capacity from third parties as supply remained constrained. Those figures and the market interpretation come from the supplied analysis, which cites company releases, filings and earnings calls dated October 28.
Capacity, Spending and Payoff
It is not yet clear how quickly either company can turn customer commitments into delivered services and recognized revenue. Microsoft’s delayed GPU deliveries are expected to affect capacity plans into the first half of 2027, while Alphabet has begun renting third-party capacity. The supplied material does not quantify how long the constraints will last or the full cost of those arrangements.
The future return on the companies’ AI spending is also unsettled. Large contract backlogs are not equivalent to completed sales, and spending plans can change as delivery schedules, equipment costs and demand develop. The source describes Microsoft’s investment as partly deferred by delivery delays; its expected later spending may put pressure on future cash flow. Alphabet’s negative free cash flow and new borrowing and share issuance are confirmed in the source, but the material does not establish how long those financing patterns will continue.
Nor can the share-price moves establish a single cause for investor decisions. The source argues that investors favored self-funded growth and penalized Alphabet’s funding needs and earnings miss. That is a reasoned reading of the results and market reaction, not a direct survey of traders or proof that investors reached a common judgment about either company’s long-term AI prospects.
Next Quarter Tests Delivery Plans
The next earnings reports will show whether Microsoft’s delayed equipment arrives and whether capital spending rises as Hood forecast. Investors will also be able to compare actual cash spending with the company’s plans for the current quarter and the first half of 2027.
For Alphabet, upcoming results will clarify whether Google Cloud can sustain rapid growth while the company finances its infrastructure build-out, and whether free cash flow improves. Both companies will need to report how supply constraints and rented or newly delivered capacity affect their ability to serve customers. Until then, the after-hours reaction is a snapshot of investor response to one set of results, not a final assessment of the AI investment cycle.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
The source attributes the contrast to Microsoft beating key forecasts and reporting positive free cash flow, while Alphabet missed revenue, earnings and search advertising expectations and reported negative free cash flow. This is an interpretation of the market response, not a confirmed account of every investor’s motivation.
Did Alphabet’s cloud business grow faster than Azure?
Yes. In the reported quarter, Google Cloud revenue grew 103% to $30.7 billion, compared with Azure growth of 48% to $33.2 billion. Faster growth did not prevent Alphabet shares from falling after the earnings report.
What does negative free cash flow mean in this comparison?
Alphabet reported negative $9.1 billion in free cash flow after investment, while Microsoft reported $18.6 billion. The source also says Alphabet raised money through bonds and new shares. These figures describe the quarter; they do not by themselves determine whether the companies’ investments will earn a return.
Are the companies able to meet AI computing demand?
Both companies said demand exceeded supply. The source reports delayed GPU deliveries for Microsoft and third-party capacity rentals by Google. The duration and full effect of the supply constraints remain unclear.
