Microsoft is a US software and cloud group founded in 1975 and headquartered in Redmond, Washington. By revenue and market value it is one of the largest technology companies in the world, with a broad footprint spanning operating systems, Office software, the Azure cloud platform and gaming (Xbox). According to stockanalysis.com, its market capitalization stood at roughly $2.90 trillion as of July 13, 2026, placing it among the most valuable publicly traded companies globally.
AI strategy
Microsoft positioned itself early as one of the central beneficiaries of generative AI. Through a multi-year, multi-billion-dollar partnership with OpenAI announced in January 2023, AI services on the Azure cloud platform and the Copilot family integrated across its product portfolio, the group brings AI capabilities into productivity software, developer tools and enterprise solutions. The centerpiece is Microsoft 365 Copilot: according to microsoft.com, the assistant runs on an enterprise context layer called "Work IQ" that connects data, context and tools into personalized answers, with building blocks spanning chat, a "Cowork" task-delegation feature, AI-powered enterprise search and Copilot Studio for custom agents. Per Wikipedia, Microsoft has also begun diversifying its model base: a "Copilot Cowork" capability unveiled in March 2026 runs on Anthropic's AI models alongside OpenAI's.
Business model
Recurring revenue from cloud subscriptions (Azure, Microsoft 365, Dynamics) forms the backbone of the business. As an AI-infrastructure provider Microsoft benefits twice: it sells compute capacity to AI providers, and it enriches its own products with AI features for which it can charge premiums. According to Microsoft's fourth-quarter fiscal 2025 results, Azure's annualized revenue surpassed $75 billion for the first time, up 34%; in the fourth quarter alone Azure grew 39%, while total Microsoft Cloud revenue reached $46.7 billion for the quarter, up 27%.
Key figures
For fiscal year 2025 (ended June 30, 2025) Microsoft reported revenue of roughly $281.7 billion, up 15%; operating income rose 17% to $128.5 billion and net income rose 16% to $101.8 billion. According to stockanalysis.com, the company employed about 228,000 people. The chairman and chief executive is Satya Nadella. The shares trade on Nasdaq under the ticker MSFT (ISIN US5949181045).
From software to platform company
Microsoft has evolved from a provider of operating systems and office software into a broadly diversified platform company. The Azure cloud division is today one of the largest providers of compute and storage capacity; it is complemented by productivity services (Microsoft 365), business applications (Dynamics), the developer platform GitHub and the LinkedIn network. This breadth gives the group many entry points to embed AI capabilities into existing products.
AI as a product layer
With the Copilot family, Microsoft introduces AI assistants across its portfolio — from Office through developer tools (GitHub Copilot) to security and business applications, built on both its own models and its collaboration with OpenAI and, more recently, Anthropic. Operating these services requires heavy investment in data centers and AI hardware, raising the business's capital intensity. Like other hyperscalers, Microsoft competes with Amazon (AWS) and Google (Google Cloud) for customers, capacity and talent.
