Apple became the first publicly traded company to reach a $3 trillion market value during intraday trading in January 2022.
Apple crossed the milestone on January 3, 2022, when its share price briefly reached the level needed to value all outstanding shares at about $3 trillion. The company did not finish that session above the threshold, which is why later reports distinguish Apple’s intraday record from Microsoft’s first close above $3 trillion.
The achievement extended Apple’s earlier market-cap records. It had become the first $1 trillion company in 2018 and the first $2 trillion company in 2020. Investors had continued to value its iPhone business, services revenue, consumer loyalty, and large installed base of devices.
A market cap is not a fixed company asset and can fall below a milestone minutes after reaching it. Share splits also affect the nominal price per share, but they do not by themselves change the company’s total market capitalization.
