Microsoft became the world’s most valuable public company by market capitalization in January 2024.
Microsoft briefly overtook Apple in market value during January 2024 trading. The change followed strong investor interest in Microsoft’s cloud business and its artificial-intelligence strategy, including the integration of AI tools into products and services.
The companies’ positions can change frequently because market capitalization depends on share prices. Apple remained one of the world’s largest companies, but concerns about iPhone demand and sales in China contributed to periods when its shares lagged Microsoft’s.
Being the most valuable public company does not mean having the greatest revenue, profit, assets, or economic importance. It means that investors, at that moment, assigned the highest total value to the company’s publicly traded equity.
