Microsoft became the first company to close a trading session above a $3 trillion market capitalization in January 2024.
Microsoft achieved the closing milestone on January 24, 2024, when its shares finished above the price required for a $3 trillion valuation. Apple had briefly touched that level in 2022, but Microsoft was the first to finish an entire trading session above it.
The company’s market value was supported by its cloud-computing business, enterprise software, Windows, gaming, and investor enthusiasm about artificial intelligence. Microsoft’s investment and partnership with OpenAI also made it a central company in the AI market-cap surge.
Market capitalization is not fixed: it changes as the share price moves and as the number of shares changes. Microsoft later competed closely with Apple and Nvidia for the title of the world’s most valuable publicly traded company.
