Microsoft’s market capitalization passed $2 trillion in 2021, making it the second U.S. company to reach that level.
Microsoft crossed the $2 trillion valuation threshold in June 2021, following Apple’s earlier achievement in 2020. The milestone reflected investor confidence in Microsoft’s cloud-computing growth, especially Azure, as well as the durability of its Windows, Office, enterprise-software, and gaming businesses.
Microsoft’s business had changed significantly from its earlier identity as primarily a personal-computer software company. Subscription software, cloud infrastructure, professional networking, gaming, and enterprise services broadened its revenue base. The company’s transformation under CEO Satya Nadella was central to the market’s reassessment of its growth prospects.
Market-cap milestones depend on share price and the number of shares outstanding, so the exact date can vary between intraday and closing calculations. Microsoft’s 2021 crossing is generally reported as an intraday event, while later records often distinguish closing valuations more carefully.
