Apple was the first company to reach a $3 trillion market capitalization on a closing stock-market basis.
Apple finished a trading session valued above $3 trillion on June 30, 2023. It had briefly touched that level during trading in January 2022, but a closing record requires the share price to remain high enough at the end of the session.
The distinction matters because financial headlines may describe an intraday record and a closing record separately. Both use market capitalization, but one is based on the highest price reached during trading and the other on the official closing price.
Apple’s valuation reflected the combined importance of its devices, operating systems, services, and global customer base. Market capitalization remains a moving figure rather than a permanent company attribute.
