Microsoft became the second public company to close above a $3 trillion market capitalization in January 2024.
Microsoft reached the milestone on January 24, 2024, after its shares rose on optimism about cloud computing and artificial-intelligence products. Apple had been the first public company to close above $3 trillion, so Microsoft’s achievement marked a new level for the rivalry between the two technology companies.
Microsoft’s modern valuation reflects businesses far beyond its original Windows software. Azure provides cloud infrastructure, Microsoft 365 supplies productivity software, and the company owns major gaming assets including Xbox and Activision Blizzard. Its partnership with OpenAI also strengthened investor interest in its AI strategy.
A market cap is not a cash balance. It represents the market value of all outstanding shares at a particular share price. Because prices change constantly, a company can cross a round-number threshold during trading and finish below it at the close.
