TL;DR
Microsoft shares rose about 4% in after-hours trading on Oct. 28, 2026, while Alphabet shares fell about 10%, despite faster reported growth at Google Cloud. The source attributes the split partly to Microsoft’s $18.6 billion in free cash flow, Alphabet’s $9.1 billion cash outflow, and Alphabet’s misses on revenue, earnings per share and search advertising.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading on Oct. 28, after the two companies reported results that put their AI spending and cash generation in focus. Alphabet’s Google Cloud grew faster than Microsoft’s Azure, but Alphabet reported negative free cash flow and missed analyst forecasts on revenue, earnings per share and search advertising, according to the source material.
Microsoft reported quarterly revenue of $92.3 billion, up 19%, and adjusted earnings per share of $4.89. Analysts polled by LSEG had expected $4.73, CNBC reported. Azure revenue rose 48% to $33.2 billion, above the 45% growth rate Microsoft had guided to in July. The company disclosed Azure revenue in dollars for the first time in this report.
Alphabet reported Google Cloud revenue of $30.7 billion, up 103%. The faster growth did not prevent the stock’s decline. The source says Alphabet’s revenue, earnings per share and search advertising results fell short of analyst forecasts; CNBC described it as the company’s first revenue and profit miss in nearly four years. The materials do not provide the actual forecast and reported figures for each of those measures.
The companies’ cash figures differed sharply. Microsoft reported $18.6 billion in free cash flow, while Alphabet recorded negative $9.1 billion, its second consecutive negative quarter, according to the source. Alphabet raised $28.7 billion through bond sales and $12.4 billion by issuing shares during the quarter, and did not buy back shares. Those financing details are reported in the source material; they do not by themselves establish how investors assessed the company’s long-term investment plans.
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 Shaped the Stock Split
The after-hours divergence shows that investors were weighing more than the headline growth rate in cloud computing. Alphabet Cloud’s 103% growth outpaced Azure’s 48%, but the source’s comparison points to cash generation, spending and results against expectations as key parts of the market reaction. Growth that requires heavy investment can be viewed differently from growth accompanied by substantial free cash flow.
That distinction matters because both companies are spending heavily to build AI computing capacity. Microsoft’s positive cash flow gives it a different near-term funding position from Alphabet’s reported cash outflow. Alphabet’s bond and share issuance provided financing during the quarter, while Microsoft had not tapped the bond market, according to the source. These are conditions at one point in time, not proof of which company’s investment will produce better returns.
Capacity is also constrained. The source reports that both companies said demand exceeded available supply, with Microsoft facing delayed GPU deliveries and Google renting capacity from third parties. Customers’ contracted commitments—$677 billion for Microsoft and $561 billion for Google Cloud—are not equivalent to cash already received. They represent future contracted revenue, much of which is not expected to be recognized quickly.

Cloud Growth Meets Rising Investment
The results were published after U.S. markets closed on Oct. 28, 2026. The source compares four factors: planned capital spending, cloud growth relative to investment, free cash flow and the availability of computing capacity. It characterizes the market response as a preference for self-funded growth, but that is the author’s interpretation of the share moves rather than a direct statement from investors as a group.
Both companies plan substantial investment. Microsoft’s 2026 capital spending plan was about $170 billion, down from an estimate of about $175 billion in July, while Alphabet’s plan was $195 billion to $205 billion, unchanged, according to the source. Both also indicated higher spending in 2027. The figures and plans do not mean that every planned dollar was spent in the reported quarter.
Microsoft reported $45.2 billion in capital spending when finance leases were included, and $39.4 billion in cash paid for property and equipment, compared with $19.4 billion a year earlier. The source says spending was below analysts’ $50.7 billion estimate cited by StreetAccount via CNBC because some expected third-party capacity deliveries were delayed. Microsoft CFO Amy Hood said on the earnings call that those delays affected the quarter. The company expects capital spending above $50 billion in the current quarter, according to the source.
Spending, Capacity and Returns Remain Unclear
The reported quarter does not settle whether either company’s AI investment will earn returns sufficient to cover its cost. The source says customer commitments are large, but only about 30% of Microsoft’s $677 billion commercial remaining performance obligation is expected to become revenue within 12 months; the average contract duration is 2.3 years. Commitments are not the same as recognized revenue or cash collected.
Microsoft’s delayed capacity deliveries may shift spending into later quarters, so its positive free cash flow in this period does not necessarily show the full cash burden of its planned build-out. Hood expected capital spending above $50 billion in the next quarter and acceleration in the first half of 2027, according to the source. The timing and eventual cost of those projects remain subject to delivery and build-out schedules.
For Alphabet, the source identifies negative free cash flow and external financing but does not give enough detail to determine how much of the cash outflow reflects temporary timing versus sustained spending pressure. Nor does it provide the exact analyst estimates and reported values for each missed measure. The after-hours share moves can change when regular trading resumes and do not establish investors’ longer-term view.
Investors Watch the Next Spending Quarter
The next near-term test is whether the companies can convert constrained AI capacity and contracted demand into recognized revenue while managing the cash required to expand. Microsoft’s stated expectation of more than $50 billion in capital spending in the current quarter and faster investment in the first half of 2027 gives investors a specific spending milestone to monitor.
Investors will also look for updates on delayed GPU deliveries, Google’s use of third-party capacity, cloud growth and free cash flow. The source does not provide a comparable next-quarter spending forecast for Alphabet beyond its 2026 plan and indication of higher investment in 2027. The companies’ subsequent earnings reports and calls should clarify whether capacity constraints are easing and how much of the spending is being funded from operations or outside financing.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
The source reports that Microsoft beat analyst expectations on revenue, profit and its Azure growth outlook, while Alphabet missed forecasts on revenue, earnings per share and search advertising. It also highlights Microsoft’s $18.6 billion in free cash flow versus Alphabet’s negative $9.1 billion. These factors may help explain the contrasting after-hours moves, but they do not prove a single cause for investors’ reaction.
Did Google Cloud grow faster than Azure?
Yes. In the reported quarter, Google Cloud revenue rose 103% to $30.7 billion, while Azure revenue rose 48% to $33.2 billion, according to the source material. The growth rates refer to revenue growth, not profit or free cash flow.
How much free cash flow did each company report?
The source reports $18.6 billion of free cash flow for Microsoft and negative $9.1 billion for Alphabet. It describes Alphabet’s result as its second negative free-cash-flow quarter in a row.
Are the cloud backlogs cash already received?
No. The source gives commercial customer commitments of $677 billion for Microsoft and $561 billion for Google Cloud, but these are future contracted amounts, not cash already collected. It says about 30% of Microsoft’s remaining performance obligation is expected to become revenue within 12 months.
