Apple developed the iPhone and became the first publicly traded company valued at US$3 trillion.
Apple reached the US$3 trillion market-capitalization milestone briefly during intraday trading on January 3, 2022. The valuation was calculated by multiplying the company's share price by its total number of outstanding shares, so it could move above or below the threshold as the stock price changed.
Apple introduced the first iPhone in 2007, combining a mobile phone, widescreen iPod, and internet-communications device. The iPhone became the company's central product and helped build a large ecosystem of services, accessories, and other devices.
Apple's market-cap milestone is distinct from revenue or profit records. It describes investors' valuation of the company at a particular share price, not money Apple earned during a year.
