TL;DR
Microsoft shares rose about 4% in after-hours trading while Alphabet’s fell about 10% after both reported results on October 28, 2026. The companies’ cloud businesses grew quickly, but investors faced different signals on earnings, free cash flow and how each company is financing AI infrastructure spending.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading on October 28, after the companies reported results that offered contrasting signals about the cost and financing of their AI build-outs. Alphabet’s Google Cloud grew faster than Microsoft’s Azure, but Microsoft reported $18.6 billion in free cash flow, while Alphabet reported a $9.1 billion outflow, according to the figures in their releases and filings cited by ThorstenMeyerAI.com.
Both companies reported rapid cloud growth. Azure revenue rose 48% to $33.2 billion, while Google Cloud revenue increased 103% to $30.7 billion. Microsoft also beat analyst expectations for revenue and profit, and Azure growth exceeded the 45% guidance it gave in July. Alphabet missed analyst forecasts for revenue, earnings per share and search advertising, according to the source report, which cited CNBC.
The cash figures reflected different financing positions during a period of heavy investment. Alphabet’s quarter included $28.7 billion raised through bonds and $12.4 billion from new share sales; the source says it did not buy back shares. Microsoft had not issued new bonds during the quarter. The figures are not, on their own, proof that either company’s long-term AI strategy will succeed or fail.
Both businesses also signaled that computing capacity remains tight. Microsoft said some third-party capacity deliveries expected during the quarter were delayed, while Google had begun renting capacity from outside providers, according to the source. Microsoft’s commercial remaining performance obligations rose 73% to $677 billion, while Google Cloud customer commitments were reported at $561 billion. Those commitments represent contracted business, not cash already received: Microsoft said about 30% of its figure was expected to become revenue within 12 months.

Same night, opposite verdicts.

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 Spending Risk
The market reaction suggests investors were weighing more than cloud growth. Revenue growth shows customer demand, but it does not show how much cash is left after building or leasing the computing capacity needed to serve that demand. In the figures reported, Microsoft generated cash after investment while Alphabet’s spending exceeded its available cash flow.
That distinction matters because both companies are committing large sums to infrastructure while demand remains ahead of available capacity. If spending is financed with borrowing or share issuance, the company takes on financing costs or dilutes existing shareholders. These are different risks from a slowdown in customer demand, and investors may value them differently.
The results do not settle which company will earn more from AI over time. Alphabet’s faster cloud growth is a meaningful operating result; Microsoft’s cash generation and earnings beat are separate strengths. The contrast is better read as a snapshot of financial exposure and execution, not a verdict on the eventual winner.

Cloud Growth Meets Capacity Limits
The companies reported results for the quarter on October 28, following a period of steep investment in data centers and computing equipment. Microsoft’s fiscal year begins in July, making the reported period its first quarter of fiscal 2027. The source report says both firms maintained their 2026 capital-spending plans while pointing to higher spending in 2027.
Microsoft reported capital spending of $45.2 billion including finance leases, and cash paid for property and equipment of $39.4 billion, compared with $19.4 billion a year earlier. The distinction matters: lease commitments and cash payments are different measures. Microsoft CFO Amy Hood said delayed third-party deliveries held down spending in the quarter and expected capital spending above $50 billion in the current quarter.
The backlog figures also need care. Microsoft’s $677 billion commercial remaining performance obligation is contracted revenue not yet recognized, with an average duration of 2.3 years, according to the source report. It is not equivalent to revenue already earned or cash on hand. Alphabet’s reported Google Cloud commitments are likewise a measure of future business, not immediate liquidity.
“Some third-party capacity deliveries we expected in Q1 were delayed.”
— Microsoft CFO Amy Hood, as quoted in the earnings-call account cited by ThorstenMeyerAI.com
Backlogs Do Not Guarantee Returns
The results do not show how quickly either company will turn AI infrastructure spending into durable profits. Customer commitments are not recognized revenue, and the timing of capacity delivery can shift both spending and the revenue companies can serve. Microsoft’s delayed deliveries are expected to move into later periods, but the source does not specify the full schedule or eventual cost.
It is also unclear how long Alphabet will need external financing at the reported level, or how its spending and free cash flow will change in coming quarters. The earnings-day market moves show investors’ immediate response, not a settled assessment of future returns. The source report’s comparisons of spending growth are its calculations from company cash-flow statements; the companies use different reporting measures, so the figures should not be treated as perfectly interchangeable.
Watch Spending and Capacity Delivery
The next evidence will come from quarterly results and company updates on capital spending, free cash flow, cloud revenue and infrastructure capacity. Microsoft said it expected capital spending above $50 billion in the current quarter and an acceleration in the first half of 2027. Its delivery delays and the timing of that planned spending will show whether the quarter’s cash-flow result persists.
For Alphabet, investors will be watching whether Google Cloud’s growth continues and whether the company’s cash flow improves as its investment proceeds. The companies’ customer commitments will matter most as they convert into reported revenue and cash. Until then, the latest results establish a contrast in current financing and operating signals, not the final outcome of their AI investments.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
Microsoft beat analyst forecasts for revenue and profit and reported positive free cash flow. Alphabet missed forecasts for revenue, earnings per share and search advertising, and reported negative free cash flow. Those results came alongside strong cloud growth at both companies.
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. Growth rates do not by themselves show which business is more profitable or has the stronger long-term outlook.
What does negative free cash flow mean for Alphabet?
The source report gives Alphabet’s free cash flow as negative $9.1 billion for the quarter, meaning cash flow after investment was negative under the measure cited. The report also says Alphabet raised money through bonds and new shares. One quarter does not establish its future financing needs.
Are the reported cloud commitments cash already received?
No. Commitments and remaining performance obligations refer to contracted business that has not yet been recognized as revenue. Microsoft said about 30% of its $677 billion backlog was expected to become revenue within 12 months.
Do these results show which company will win the AI market?
No. They show current cloud growth, spending, financing and capacity constraints. The results do not establish which company will generate the greatest long-term returns from AI.
