Microsoft became the second U.S. company to exceed a $2 trillion market capitalization in June 2021.
Microsoft crossed the threshold on June 24, 2021, following Apple’s earlier achievement. Its valuation was supported by strong growth in cloud computing, particularly Azure, along with software subscriptions, enterprise services, and the company’s established Windows and Office businesses.
The market-cap milestone came during a broader period when investors assigned high valuations to large technology companies. Microsoft’s transformation from a primarily personal-computer software company into a diversified cloud and services business was central to its rising market value.
Market capitalization changes continuously with share prices, so a company can move above or below a threshold without any change in its number of employees or physical assets. Microsoft later competed directly with Apple, Saudi Aramco, and Nvidia for the top position among the world’s most valuable listed companies.
