Microsoft became the second technology company to exceed a $2 trillion market capitalization.
Microsoft passed the $2 trillion level in June 2021, following Apple’s earlier achievement. Investor enthusiasm centered on Microsoft’s cloud-computing business, enterprise software, subscriptions, and recurring revenue model.
Microsoft’s business changed substantially from its earlier identity as a personal-computer software company. Windows and Office remained important, while Azure cloud services, Microsoft 365, LinkedIn, gaming, and enterprise products broadened its sources of revenue.
Market-cap rankings can vary depending on the exact date and whether a source uses an intraday value or a closing value. This question refers to Microsoft’s crossing of the $2 trillion threshold, not to becoming the first company ever to reach it.
