Microsoft

Microsoft sits at ~$3.1 trillion in market cap, a position anchored by its dominant enterprise cloud platform Azure, its productivity suite Microsoft 365, and its strategic $13 billion investment in OpenAI. The integration of Copilot AI features across Word, Excel, Teams, and GitHub has accelerated enterprise adoption and driven premium pricing power that few software companies have ever achieved. Azure's share of cloud computing revenue continues to grow, narrowing the gap with AWS.
