Microsoft became the second publicly traded company to exceed a US$3 trillion market capitalization, in January 2024.
Microsoft’s shares reached the threshold on 24 January 2024, briefly valuing the company above $3 trillion during trading. Apple had been the first company to attain that level in 2022, making Microsoft’s achievement a distinct second-place milestone rather than the first of its kind.
Investor enthusiasm reflected Microsoft’s cloud business, recurring software subscriptions and its substantial investment in artificial-intelligence technology. Market capitalization changes continuously with share prices, so reports may distinguish an intraday crossing from a closing valuation. Microsoft was founded in 1975 and became a major software, cloud-computing and enterprise-services provider through products including Windows, Office and Azure.
