Microsoft became the first company to exceed a $3 trillion market capitalization during trading in January 2024.
Microsoft passed the milestone on January 24, 2024, during a period when investors strongly rewarded its cloud and artificial-intelligence businesses. Its market value briefly moved above $3 trillion as the share price rose, making it the second company after Apple to reach that level and the first to exceed it during that trading session.
The company’s modern valuation is supported by several large businesses: Azure cloud computing, Windows, Office, gaming, and enterprise software. Microsoft’s multibillion-dollar partnership with OpenAI also intensified attention on its AI strategy.
Market-cap records can change quickly because they depend on share prices and the number of shares outstanding. Microsoft later traded places with Apple at the top of global-company rankings, so reports from different dates may list a different leader.
