Apple was the first publicly traded company to reach a US$2 trillion market capitalization, doing so in August 2020.
Apple achieved the milestone when its share price rose above the level required to value all outstanding shares at US$2 trillion. Strong iPhone sales, growth in services such as the App Store and Apple Music, and investor confidence in the company’s ecosystem supported the rally.
The achievement came only about two years after Apple became the first US$1 trillion public company. Apple later became the first company to close a trading session above US$3 trillion in January 2022, illustrating how quickly mega-cap valuations can change.
The milestone applies to market capitalization, not annual sales. It also differs from enterprise value, which adjusts market capitalization for debt and cash. News reports may use intraday or closing figures, so the exact date can vary by definition.
