TL;DR
Microsoft shares rose about 4% in after-hours trading after its October 28 results, while Alphabet shares fell about 10%. Both companies reported rapid cloud growth and heavy AI investment, but investors focused on Microsoft’s positive free cash flow, Alphabet’s negative free cash flow and Alphabet’s revenue and earnings misses.
Microsoft shares rose about 4% and Alphabet shares fell about 10% in after-hours trading Wednesday, after the companies reported quarterly results that showed fast cloud growth but different financial pressures. Alphabet’s Google Cloud grew faster than Microsoft Azure, yet Alphabet reported negative free cash flow and missed analyst forecasts for revenue, earnings per share and search advertising, while Microsoft beat key expectations and remained cash-flow positive.
Microsoft reported $92.3 billion in revenue, up 19% year over year, for its first fiscal quarter of 2027. Adjusted earnings per share were $4.89, above the $4.73 expected by analysts surveyed by LSEG, according to CNBC. Azure revenue rose 48% to $33.2 billion, exceeding Microsoft’s July forecast of 45%. The company disclosed Azure quarterly revenue in dollars for the first time in these results.
Alphabet reported Google Cloud revenue of $30.7 billion, up 103% year over year. But the growth came alongside a 114% increase in capital spending, according to the source’s calculations from company cash-flow statements. Alphabet’s free cash flow was negative $9.1 billion, its second consecutive negative quarter. It raised $28.7 billion through bonds and $12.4 billion by issuing shares during the quarter, and made no share buybacks, the source reported.
Microsoft’s free cash flow was $18.6 billion. It spent $39.4 billion in cash on property and equipment, compared with $19.4 billion a year earlier; spending including finance leases was $45.2 billion. Microsoft’s reported capital spending was below the $50.7 billion analysts expected, with CFO Amy Hood attributing the gap partly to delayed deliveries of third-party capacity. She said spending would exceed $50 billion in the current quarter and accelerate in the first half of 2027.

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 Bet
The contrasting share moves show that investors were weighing more than cloud growth. Rapid revenue gains require substantial infrastructure spending, and the companies’ ability to fund that investment from ongoing operations can affect how much financial risk investors see. Microsoft’s positive free cash flow gave it a different funding position from Alphabet, even though Alphabet’s cloud business grew faster.
The figures do not establish which company will ultimately earn more from AI. They do show that current demand is not translating into equivalent cash outcomes: both firms are investing heavily, but Alphabet’s reported spending exceeded its cash generation this quarter. Its bond and share sales provided additional funding, while Microsoft said it expects to remain free-cash-flow positive this fiscal year and could seek other funding if attractive.
Investors also had company-specific reasons to distinguish the results. Microsoft beat expectations on revenue, profit and Azure growth. Alphabet missed expectations for revenue, earnings per share and search advertising, according to CNBC. That combination made Alphabet’s spending and cash-flow picture more concerning to the market, despite Google Cloud’s strong growth.

Cloud Growth Meets Capacity Limits
The companies’ results arrived amid strong demand for AI computing and constraints on the capacity needed to serve it. Both said demand exceeded supply. Microsoft reported that some expected GPU and other capacity deliveries had slipped, while Alphabet had begun renting capacity from third parties. These constraints can delay both spending and the revenue companies hope to earn from new infrastructure.
Microsoft’s commercial remaining performance obligation, or contracted revenue not yet recognized, rose 73% to $677 billion. The company said about 30% is expected to become revenue within 12 months, with an average contract duration of 2.3 years. Alphabet’s Google Cloud backlog was reported at $561 billion. Those commitments indicate contracted demand, but they are not cash already received, and delivery timelines matter.
The companies’ spending plans also point to further investment. Microsoft’s 2026 capital expenditure plan was about $170 billion, down from its July indication of about $175 billion, while Alphabet maintained a 2026 plan of $195 billion to $205 billion and indicated a large increase in 2027. The figures are not directly interchangeable across companies, and planned spending is distinct from cash spent in a given quarter.
Spending and Delivery Risks Remain
The share-price moves are an immediate market reaction, not proof that either company’s AI investments will generate a particular return. Revenue timing, infrastructure delivery and future cash generation remain uncertain. Backlogs represent contracted commitments, but only part is expected to convert to revenue in the near term, and the companies did not provide a single timetable for fulfilling all orders.
Microsoft’s current-quarter spending is expected to exceed $50 billion, and Hood said investment would accelerate in the first half of 2027. That makes its positive free cash flow this quarter an incomplete measure of the cash demands ahead. For Alphabet, the reported bond and share issuance shows how it financed activity during this quarter, but the source material does not establish how long negative free cash flow will continue or what future financing mix it will use.
Alphabet’s misses also need to be read against the analyst forecasts and business lines cited in the report. The source says this was its first miss on both revenue and profit in nearly four years, citing CNBC; the companies’ future results will determine whether the quarter signals a lasting change or a temporary setback. The after-hours share moves may also change as investors assess the results further.
Watch Spending Through 2027
Investors will watch Microsoft’s next quarterly report for whether spending rises above $50 billion as Hood forecast, and whether delayed capacity arrives on schedule. The company’s guidance points to faster investment during the first half of 2027, while management has said demand continues to exceed supply.
For Alphabet, upcoming results will show whether Google Cloud’s rapid growth can be accompanied by improved cash generation and whether the company’s high investment plans persist. Investors are also likely to track search advertising performance after its reported miss and the extent to which new capacity can be secured through third-party providers.
Across both companies, the key measures are likely to include cloud revenue growth, capital spending, free cash flow and how quickly contracted commitments become recognized revenue. The current results offer a snapshot of growth and funding, but not a final verdict on the returns from their AI infrastructure investments.
Key Questions
Why did Microsoft shares rise while Alphabet shares fell?
Microsoft beat analyst expectations for revenue and adjusted earnings per share, and Azure grew 48%. Alphabet’s Google Cloud grew faster, but Alphabet missed forecasts for revenue, earnings per share and search advertising, and reported negative $9.1 billion in free cash flow.
Did Google Cloud grow faster than Microsoft 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 alone do not show how much cash each business generated or how much it cost to build capacity.
How did the companies’ free cash flow compare?
Microsoft reported $18.6 billion in positive free cash flow. Alphabet reported negative $9.1 billion, its second consecutive negative quarter, according to the source material.
Are AI computing shortages affecting both companies?
Both companies said demand exceeded available supply. Microsoft cited delayed third-party capacity deliveries, while Alphabet had started renting capacity from other providers. The full timing of additional capacity remains unclear.
Do the companies’ backlogs mean the revenue is already secured as cash?
No. Microsoft reported $677 billion in commercial remaining performance obligation and Alphabet reported a $561 billion Google Cloud backlog. These are contracted commitments, not cash already collected; Microsoft said about 30% of its commercial obligation is expected to become revenue within 12 months.
