Apple became the first public company to close a trading day above a $1 trillion valuation in 2018.
Apple reached the milestone on August 2, 2018, after its shares rose following a strong quarterly earnings report. The company’s market capitalization exceeded $1 trillion based on its share price and the number of shares outstanding at that time.
The achievement followed the iPhone’s transformation of Apple’s business. Revenue from the iPhone, together with expanding services and a strong ecosystem of devices and software, helped the company grow far beyond its earlier identity as a personal-computer maker.
The wording matters: Apple was the first to finish a trading day above $1 trillion, while intraday market-cap milestones can be reached temporarily and then lost before the closing bell. Other companies, including Microsoft and Amazon, later passed the threshold. The valuation measures equity-market value, not the company’s total enterprise value or yearly sales.
