Considering the popularity of the Windows operating system, it’s no surprise that Microsoft has consistently ranked as one of the largest companies in the world. About 62% of computers use Windows, according to Statcounter. While it's best known for Windows, Microsoft offers a diverse product line, including the Office Suite, the Azure cloud platform, and Xbox video game consoles.
Microsoft has been making a big push into AI technology. It launched an AI-powered digital assistant, Microsoft Copilot, and it's estimated it will spend $190 billion on capital expenditures in 2026. It has also been partnered with OpenAI since 2019, and after a recapitalization, it holds a roughly 27% stake in that AI company.
