Apple was the first US corporation to close a trading day above a US$2 trillion market capitalization, doing so on 19 August 2020. Its shares finished at a level that valued all outstanding stock above the landmark figure.
The achievement came only two years after Apple's US$1 trillion milestone. Strong iPhone sales, recurring services revenue and investor expectations for long-term ecosystem growth supported the rapid increase, even as the COVID-19 pandemic disrupted the global economy.
Saudi Aramco had reached a roughly US$2 trillion valuation intraday in 2019, but Apple's closing-market record specifically concerned a US corporation listed in the United States. Microsoft later became the second US company to pass the same threshold.
