Which company became the first publicly traded US company to reach a US$700 billion market capitalization?

The story behind the answer

Apple became the first publicly traded US company to reach a US$700 billion market capitalization.

Apple passed the US$700 billion mark in February 2015 as its share price rose after strong results and optimism about the iPhone 6 and iPhone 6 Plus. At the time, the valuation was roughly twice that of the next-largest US company, although rankings changed as share prices moved.

The milestone came during a period when Apple was expanding beyond its traditional computer business. The iPod had introduced many consumers to the brand, the iPhone had become its main growth engine, and the company was building an increasingly important services ecosystem.

Apple’s market capitalization is calculated from its share price and shares outstanding. It should not be confused with the company’s annual revenue or cash holdings. Apple later passed US$1 trillion in 2018, US$2 trillion in 2020, and US$3 trillion first during intraday trading in 2022.
