(New York) — Microsoft is entering a new phase of growth as artificial intelligence increasingly becomes a major engine behind the company’s expanding revenue base. In fiscal 2026, which ended June 30, 2026, Microsoft reported revenue of $331.8 billion, up 18% from the previous year. The growth came as demand accelerated for Azure, Microsoft 365 Copilot and the computing infrastructure required to support AI applications across corporate customers.
The scale of Microsoft’s cloud business shows how significant the transformation has become. Microsoft Cloud generated $214.4 billion in fiscal 2026, up 27% from $168.9 billion a year earlier, representing roughly 65% of Microsoft’s total revenue. The figure, however, should not be treated as Microsoft’s AI revenue because Microsoft Cloud also includes Microsoft 365 Commercial cloud, Azure and other cloud services, the commercial portion of LinkedIn and Dynamics 365.
Azure provides one of the clearest indicators of the impact of AI on Microsoft’s growth engine. Revenue from Azure and other cloud services increased 41% during fiscal 2026, while fourth-quarter growth reached 43% year over year. Microsoft also reported that annual Azure revenue surpassed $100 billion for the first time, marking a major milestone as cloud computing becomes increasingly central to the economics of AI.
The growth is occurring as demand for AI computing capacity continues to outpace available supply. During the fourth quarter, Microsoft added 31 data centers across five continents, bringing the total number of new data centers added during fiscal 2026 to 88. The company also said it had reduced the time required to bring new GPUs into service in its largest regions by nearly 50% over the fiscal year.
The infrastructure buildout is also changing Microsoft’s cost structure. Microsoft Cloud’s gross margin fell to 65% in the fourth quarter, reflecting a shift in business mix toward Azure as well as continued investment in AI infrastructure and higher product usage. At the same time, Microsoft’s operating income reached $155.2 billion for fiscal 2026, up 21%, while net income rose 31% to $133.7 billion.
The next layer of growth is Microsoft 365 Copilot, which is turning AI from an infrastructure business into a product sold directly to corporate customers. By the end of fiscal 2026, Microsoft 365 Copilot had surpassed 30 million paid seats, up from more than 20 million in the third quarter, while net paid seat additions more than doubled sequentially.
Copilot is strategically important because it allows Microsoft to increase the economic value of its enormous installed customer base. Microsoft 365 Commercial cloud revenue increased 14% on a reported basis in the fourth quarter, while the overall number of paid Microsoft 365 Commercial seats grew 6% year over year. Microsoft said premium offerings including Copilot, E5 and early E7 adoption contributed to average revenue per user growth during the quarter.
AI is also supporting growth across Microsoft’s Intelligent Cloud business. The segment generated $39.3 billion in fourth-quarter revenue, an increase of 32% year over year, while Azure and other cloud services increased 43%. The gap between Microsoft’s overall revenue growth of 18% and Azure’s 43% growth highlights how rapidly cloud and AI-related businesses are expanding relative to some of the company’s more mature operations.
Microsoft is simultaneously building a broader AI platform that extends beyond cloud infrastructure and Copilot. Its Foundry platform has reached 100,000 customers, with revenue more than doubling year over year, while the company said the number of Foundry customers operating at a one-trillion-token annualized run rate increased fourfold. This gives Microsoft another potential source of monetization as companies build their own AI applications and autonomous agents on the Azure platform.
The scale of future contracted business also points to continued demand for Microsoft’s cloud and AI infrastructure. Commercial remaining performance obligations reached $678 billion at the end of fiscal 2026, an 84% increase from a year earlier, with approximately 30% expected to be recognized as revenue over the following 12 months. Microsoft said sequential growth in commercial RPO was driven by customers outside frontier AI companies, suggesting that demand is spreading beyond the handful of firms developing the largest AI models.
Microsoft has not disclosed a single figure showing how much of its total revenue comes directly from AI. Azure revenue includes both AI and non-AI cloud consumption, while Microsoft 365 Commercial cloud revenue includes numerous products and services alongside Copilot. The more accurate interpretation is that AI has become a growth layer across several Microsoft businesses, accelerating Azure, Copilot, cloud consumption and enterprise software rather than appearing as one standalone revenue line.
For Microsoft, the AI race is therefore becoming much larger than selling an AI assistant or licensing a software product. The company is building a value chain spanning data centers, GPUs and computing capacity, Azure, AI models, developer platforms, Copilot and enterprise applications. With annual revenue of $331.8 billion, Azure above $100 billion, Microsoft Cloud at $214.4 billion and more than 30 million paid Microsoft 365 Copilot seats, fiscal 2026 shows that AI has moved from a technology initiative into one of the central foundations of Microsoft’s growth strategy.
