Microsoft
The cloud and AI colossus — $281.7B in annual revenue, Azure growing 34% YoY, and deep integration across every enterprise on the planet with Office 365, Windows, and Copilot AI.
Business Overview
What does Microsoft do, and why is it everywhere?
Microsoft is the operating system of global business. From the Windows PC on your desk, to the Office 365 suite you use for email and documents, to the Azure cloud that runs enterprise applications, to the Copilot AI assistant now embedded across every product — Microsoft touches virtually every knowledge worker on Earth. No other company has this level of omnipresence across the enterprise technology stack.
Founded in 1975 by Bill Gates and Paul Allen, Microsoft spent its first three decades dominating personal computing. But the real transformation came under CEO Satya Nadella (since 2014), who pivoted the company from a Windows-centric model to a cloud-first, AI-first platform. That pivot turned Microsoft from a mature, slow-growth giant into one of the fastest-growing mega-cap companies in the world.
Microsoft's business model is built on recurring subscription revenue. Office 365 Commercial ($87.8B), Azure cloud services ($75B+), and LinkedIn all generate predictable, high-margin recurring revenue. The company has also become the largest investor in OpenAI, integrating GPT technology across its entire product stack as Copilot — an AI assistant for Office, Windows, Azure, GitHub, and more.
With a record $37.5B in capital expenditure in a single quarter (invested in AI data centres), Microsoft is aggressively building out the infrastructure to capture the enterprise AI opportunity. The company has $343.5B in shareholders' equity and generated over $100B in net income — a financial fortress that can fund decades of growth.
Intelligent Cloud
Azure cloud platform, SQL Server, Windows Server, GitHub, and enterprise services. The fastest-growing segment, driven by AI workloads and cloud migration.
Productivity & Business
Office 365 Commercial & Consumer, LinkedIn, and Dynamics 365. The backbone of enterprise productivity with 98%+ renewal rates and expanding Copilot AI integration.
More Personal Computing
Windows OEM, Surface, Xbox & Gaming (including Activision Blizzard), and Search & advertising. The consumer-facing segment that funds the enterprise engine.

Moat Analysis
Five dimensions that determine competitive durability
Brand Loyalty & Pricing Power
9/10The #3 most valuable global brand ($502B brand value). Microsoft successfully priced Copilot at $30/user/month — a premium that enterprises willingly pay. Office 365 and Azure command premium pricing with near-zero churn. Enterprise bundling concentrates wallet share.
High Barriers to Entry
8/10Record $37.5B quarterly capex on AI data centres creates insurmountable infrastructure barriers. Enterprise licensing locks customers into the Microsoft ecosystem. Deep integration between Azure, Office 365, SQL Server, and Active Directory makes competing on a full-stack basis nearly impossible.
High Switching Costs
9/10This is Microsoft's strongest moat. Enterprise customers depend on Office 365, Active Directory, Azure, SQL Server, and Windows Server — all deeply intertwined. Switching means migrating documents, retraining employees, rebuilding custom applications, and re-architecting authentication systems. The cost is measured in billions and years.
Network Effect
7/10Microsoft Teams grows more valuable as more users join. Office document formats (Word, Excel, PowerPoint) create file-sharing network effects — everyone uses them because everyone else does. Active Directory and Entra ID create identity network effects across organisations. However, these are moderate compared to pure consumer platforms.
Economies of Scale
9/10Microsoft's cloud delivers computing at up to 80% lower cost than small providers. $281.7B in revenue enables R&D spending that no competitor can match. Azure's massive data centre footprint (60+ regions globally) amortises infrastructure costs across millions of customers. Software development costs are spread across 1.5+ billion users.

Growth Drivers
Where the next wave of revenue comes from
Azure & Cloud Migration
With only 30% of enterprise workloads in the cloud, the migration opportunity is massive. Azure's 34% growth rate, AI-enhanced services, and hybrid cloud capabilities position Microsoft to capture the majority of remaining enterprise cloud spend over the next decade.
Copilot AI Monetisation
Copilot is embedded across Office 365, Windows, Azure, GitHub, Dynamics, and Security. At $30/user/month, if even 20% of Office 365's 400M+ paid seats adopt Copilot, that is a $28B+ annual revenue stream. Early enterprise adoption is accelerating.
Security & Compliance
Microsoft Security is now a $20B+ annual business, growing faster than the company average. With increasing cyber threats and regulatory compliance demands, Microsoft's integrated security suite (Defender, Entra, Purview, Sentinel) is becoming mission-critical for enterprises.
Gaming & Activision
The $69B Activision Blizzard acquisition makes Microsoft the #3 gaming company globally. Xbox Game Pass, cloud gaming, and IP licensing from franchises like Call of Duty, World of Warcraft, and Candy Crush create a high-margin, recurring revenue stream in the entertainment space.
Investment Risks
Every investment has risks — here is what could go wrong
AI Capex Returns Lag
Microsoft is investing $150B+ annually in AI data centres. If enterprise AI adoption is slower than projected, or if Copilot usage plateaus below expectations, the massive capex could weigh on margins and free cash flow for years. The market expects ROI — any sign of overspending will punish the stock.
High SeverityAntitrust & Regulatory Action
EU and UK regulators are scrutinising Microsoft's cloud licensing practices. If forced to allow fair competition on rival clouds, Azure could lose a key competitive advantage. Additional antitrust action related to the Activision acquisition, Teams bundling, or OpenAI partnership could also materialise.
Medium SeverityOpenAI Partnership Risk
Microsoft's AI strategy is heavily dependent on OpenAI. Governance disputes, competitive disruption from open-source AI models, or OpenAI choosing to build its own infrastructure could undermine Microsoft's AI differentiation. The $13B+ investment concentration in a single partner is a strategic risk.
Medium SeverityLaw of Large Numbers
At $281.7B in revenue, sustaining 15% growth means adding $42B in new revenue annually — the equivalent of adding an entire Adobe every year. As the base grows, maintaining double-digit growth becomes increasingly difficult, and any deceleration could cause multiple compression.
Medium SeverityValuation & Intrinsic Value
What is this business actually worth?
As of 16 February 2026, Microsoft (MSFT) is trading at approximately 30% below its estimated intrinsic value based on our discounted cash flow model. With $281.7B in revenue, $101.8B net income, Azure growing at 34%, Copilot AI monetising across 400M+ Office seats, and one of the widest moats in technology, the market is undervaluing Microsoft's compounding power and AI-driven growth runway.
