Alphabet is the parent company behind Google; Microsoft is a separate technology company. Both compete in cloud computing, AI and productivity software, but they earn money from different mixes of businesses and report results on different fiscal calendars. Alphabet’s 2025 calendar-year revenue was $403 billion, up 15%; Microsoft reported $281.724 billion for the fiscal year ended June 30, 2025. Those figures are not same-period results and should not be read as a direct growth or size comparison.
How Alphabet and Microsoft are organized
Alphabet’s largest business is Google. Its reporting groups are Google Services, Google Cloud and Other Bets. Microsoft reports three segments: Productivity and Business Processes, Intelligent Cloud, and More Personal Computing. The labels describe each company’s own reporting structure; they are not equivalent categories.
Alphabet: Google Services, Google Cloud and Other Bets
Google Services includes Search, YouTube, Android, Chrome, Maps, Play and Pixel devices. Its revenue comes primarily from advertising, subscriptions, apps and in-app purchases, and devices, according to Alphabet’s company FAQ. Google Cloud covers infrastructure, platforms, applications and enterprise services, earning primarily through consumption-based fees and subscriptions for Google Cloud Platform, Workspace and other enterprise services. Other Bets is a collection of smaller operating businesses, including Waymo, Verily, GFiber and GV.
Microsoft: three reportable segments
Microsoft’s 2025 annual report places Microsoft 365 and LinkedIn in Productivity and Business Processes; Azure and other cloud services and server products in Intelligent Cloud; and Windows, gaming and search advertising in More Personal Computing. Microsoft 365 cloud products therefore sit outside the segment where much of its infrastructure cloud revenue is reported.

What the reported financial figures show—and do not show
| Company and period | Reported figure | What it covers |
|---|---|---|
| Alphabet, calendar year 2025 | $403 billion consolidated revenue, up 15% | Alphabet as a whole; the reported year is the calendar year. |
| Alphabet, fourth quarter of 2025 | $95.5 billion Google Services revenue; $17.7 billion Google Cloud revenue | Two separate Alphabet segments for the quarter. |
| Microsoft, fiscal year 2025 | $281.724 billion revenue | Microsoft’s fiscal year ended June 30, 2025. |
Alphabet’s figures come from its 2025 results; Microsoft’s fiscal-year figure is from its annual report. The periods differ, so the totals do not establish which company grew faster over a common 12-month period. Nor do these figures alone establish relative profitability, market share or product quality. Alphabet CEO Sundar Pichai said in the February 4, 2026 earnings call that “Alphabet annual revenues exceeded $400 billion for the first time.”
How Google Cloud and Microsoft Azure compare
The useful comparison is between products and customer needs, not the companies’ segment names. Google Cloud is a broad portfolio spanning infrastructure, platforms, applications and enterprise services. Microsoft describes Azure as a set of cloud services for building, deploying and managing applications across platforms and devices. Microsoft reports Azure and other cloud services chiefly in Intelligent Cloud, while Microsoft 365 cloud products are in Productivity and Business Processes.

| Dimension | Google Cloud | Microsoft cloud offerings |
|---|---|---|
| Scope in company reporting | A distinct Alphabet segment covering infrastructure, platforms, applications and enterprise services. | Azure and other cloud services are principally in Intelligent Cloud; Microsoft 365 cloud products are in Productivity and Business Processes. |
| Revenue model described by the company | Primarily consumption-based fees and subscriptions for Google Cloud Platform, Workspace and other enterprise services. | The cited annual report describes Azure and other cloud services; a directly comparable revenue-model breakdown is not stated there. |
| Customer use | Cloud platform and enterprise services, including Workspace. | Azure supports application development, deployment and management; Microsoft 365 serves productivity needs. |
For a business evaluating providers, compare the particular workloads, applications, productivity tools and services it needs; the reporting categories do not provide a like-for-like product or performance test.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Where the companies overlap—and where comparison is limited
Their clearest overlap is cloud and AI services, alongside productivity and collaboration software. Alphabet combines a large advertising and consumer-services business with cloud and smaller ventures. Microsoft combines productivity software, cloud and server services, Windows, gaming and search advertising. That different mix means consolidated revenue says little by itself about which provider is the better fit for a particular customer.
Microsoft says Azure competes with cloud providers and open-source offerings, and that its AI products face competition from hyperscalers, emerging competitors and open-source offerings. The cited company materials describe businesses and report company results; they do not independently assess product quality or market share. Alphabet’s FAQ states that its information is as of September 30, 2025, so product and business details may change.

Which comparison should you use?
- For business structure: Compare Alphabet’s Google-centered portfolio and Other Bets with Microsoft’s three reportable segments, keeping their scopes distinct.
- For financial performance: Align reporting periods and compare segment-level measures with matching definitions before drawing conclusions from revenue totals.
- For cloud or productivity choices: Compare the actual services and workloads you need rather than assuming that similarly named reporting segments represent equivalent products.
