Microsoft became the first company to reach a $3 trillion market capitalization on a closing basis in January 2024.
Microsoft ended trading above a $3 trillion valuation on January 24, 2024. The company had briefly become the world’s most valuable listed company earlier that month as investors focused on cloud computing and artificial-intelligence opportunities.
Microsoft’s businesses span Windows, Office, Azure, gaming, enterprise software, and professional networking through LinkedIn. Its investment in OpenAI also increased attention on its position in generative AI.
A frequent source of confusion is the difference between an intraday market-cap milestone and a closing milestone. A company can cross a threshold while markets are open but finish below it; this question refers specifically to the closing value.
