What Alphabet actually reported
Microsoft's own June-quarter release is the Azure side of the comparison. First, the Google side.
Alphabet's release for the quarter ended June 30, 2026, says Google Cloud revenue increased 82% to $24.8 billion. Alphabet attributed the growth to enterprise AI solutions, enterprise AI infrastructure and core GCP services. Consolidated revenue rose 24% to $119.8 billion.
Reuters reported that analysts on average had expected a 64% increase for Google Cloud, according to LSEG data. That makes 82% a big beat, not just a strong number.
Alphabet's filing also puts Google Cloud's remaining performance obligations (RPO) at $513.9 billion. RPO is contracted revenue that hasn't been recognized yet. It is not near-term revenue, and it is not a forecast.
The Azure side: a period mismatch to watch
Microsoft's fiscal year ends in June, so Alphabet's calendar Q2 is Microsoft's fiscal Q4. That matters because Microsoft's "FY26 Q2" investor metrics page covers the December 2025 quarter. On that page Azure grew 39%, or 38% in constant currency. It is not the quarter TIKR is comparing, and it shouldn't be used to check TIKR's June-quarter figures.
For the June 2026 quarter, other reporting says:
- Microsoft's Azure and other cloud services grew 43% (unchanged in constant currency) in the fiscal fourth quarter.
- Microsoft later reshuffled its reporting. According to the Motley Fool, GitHub's cloud services and a couple of other businesses moved out of Azure, which cut the June quarter's growth rate to 42%.
- The same piece says the June quarter's restated Azure revenue was $29.4 billion. It adds that the Oct. 28 report will be the first to give Azure's quarterly revenue in dollars.
So TIKR's 42% and $29.4 billion are consistent with the restated basis. They are not the figures from Microsoft's original July release, which showed 43%. Neither is a perfect match for Google Cloud's segment, which includes Workspace and TPU system sales.
On annual scale, Azure is still well ahead. Microsoft said Azure surpassed $100 billion, up 41% for the fiscal year. CNBC noted that at that size the business trails Amazon Web Services while remaining larger than Alphabet's Google Cloud.
The "lapping" math, and why to be careful with it
TIKR's logic is simple compounding. It applies each business's latest year-over-year growth rate for four more quarters:
- Google Cloud: $24.8 billion × 1.82 ≈ $45 billion.
- Azure: $29.4 billion × 1.42 ≈ $42 billion.
This is a thought experiment, not a forecast. Sustaining 82% growth on a base this large is unusual. Microsoft has guided differently from TIKR's framing, too. Amy Hood projected 45% Azure growth at constant currency for the fiscal first quarter. The 44% to 45% range TIKR mentions matches reporting from other outlets.
The comparison is also sensitive to a few things:
- Year-over-year growth versus sequential growth. Growth rates compound against a base, and the Azure base was restated.
- Capacity. Alphabet's own reported cloud growth came while compute went to internal AI work. Both companies say demand exceeds capacity. Azure's growth mainly depends on how fast Microsoft can add more capacity.
- Segment definitions. Google Cloud includes Workspace and, per Alphabet, product revenue from sales of TPU systems. Reuters noted that Google began recognizing revenue from direct sales of its TPU chips for the first time in the quarter. That may make the 82% less comparable with Azure's growth.
The cost side: capex and cash flow
The part of TIKR's story that holds up best is the cost. Reuters reported that Alphabet now expects $195 billion to $205 billion in capital expenditures this year, up from $180 billion to $190 billion. It also said Alphabet reported negative free cash flow for the first time in its history, burning $5.9 billion. That matches TIKR's figures.
Microsoft is spending heavily too. Reporting on its fiscal Q4 says capital expenditures were about $41 billion in the quarter, and that Microsoft Cloud gross margin fell to 65% in the fourth quarter, down from 68% in the prior quarter. CNBC-sourced coverage says Microsoft's calendar-2026 capex guidance came down to about $175 billion from roughly $190 billion. This is not a "Google spends, Microsoft saves" story. Both are spending enormous sums to add capacity, and investors are judging the two on whether that spending turns into cloud margins.
Some TIKR claims I couldn't independently confirm. These are the buyback halt, the doubling of long-term debt in six months, and the 7% share drop after the report. Reuters reported shares down about 3% in extended trading that evening. Alphabet's release also describes a June 2026 equity raise with net proceeds of $49.6 billion, which is relevant to how it is funding the build-out. TIKR's valuation points are its own analysis: roughly 24x forward earnings, a 23x five-year average, and analyst consensus. Treat those as opinion and third-party data, not company disclosures.
What to watch on October 28
Alphabet and Microsoft are scheduled to report on October 28, 2026, so this is still a forward-looking story. Based on the evidence above, these are the things to watch:
- Azure in dollars. Microsoft's first reported Azure revenue figure will show whether the $29.4 billion restatement holds and how big the gap really is.
- Azure growth against guidance. Microsoft guided 44% to 45% in constant currency.
- Google Cloud margin and growth. TIKR flags margin as the key number, since it expects rented outside capacity to weigh on it. The prior-quarter margin was 35.6%, up from 20.7% a year earlier.
- Capex and free cash flow at both companies. Spending is the price of the capacity that both say they lack.
- Capacity comments. Both say demand exceeds supply, so growth depends on how quickly new capacity comes online.
Why Windows and Microsoft admins should care
This is a financial story, but it has practical consequences. Azure growth and capacity affect pricing, regional availability and the pace of new AI services in Azure, Copilot, Fabric and the rest of the Microsoft stack. If a rival is gaining share in AI infrastructure, expect more aggressive commit discounts and more multicloud pitches. Capacity limits could also keep delaying GPU-heavy workloads for customers on either platform.
Overall, Google Cloud's 82% growth and $513.9 billion backlog make it a serious competitor. But "Google Cloud passes Azure within a year" rests on one quarter's growth rate and a restated Azure base, and Azure is still larger on annual revenue. This isn't a prediction of the final outcome, and Oct. 28 will be the first real test of it.
