Apple first surpassed a US$3 trillion market capitalization in January 2022.
The milestone occurred during trading on January 3, 2022, when Apple’s share price briefly rose above the level required for the company’s outstanding shares to be worth three trillion dollars. It was the first public company to reach that valuation.
Apple’s market value had expanded through the growth of the iPhone ecosystem and increasing contributions from services such as the App Store, cloud services, payments, music, and video. Investors also closely watched the company’s product announcements and financial results.
The figure was an intraday market value, not a permanent closing valuation. Stock prices fluctuate, so a company can cross a round-number threshold briefly and later fall below it without any change to the definition of market capitalization.
