Microsoft was the first company to reach a $3 trillion market capitalization during 2024, crossing the threshold on January 24.
Its shares rose during trading as investors valued the company’s cloud-computing business, enterprise software, and growing involvement in artificial intelligence. Microsoft had previously crossed $2 trillion in 2021, placing it among the small group of companies capable of sustaining exceptionally large valuations.
Market-cap records are momentary measurements rather than permanent rankings. A company can become the most valuable in the world during one session and later be overtaken as share prices move. The exact result also depends on whether a source uses intraday capitalization or closing prices.
Microsoft was founded by Bill Gates and Paul Allen in 1975. Its modern valuation reflects businesses far beyond its original personal-computer software, including Azure, Microsoft 365, gaming, and professional networking.
