Apple was the first public company in the United States to reach a $1 trillion market capitalization.
Apple crossed the milestone on August 2, 2018, when trading lifted its share price high enough for the company’s total equity value to exceed $1 trillion. The calculation includes all outstanding shares, not merely the shares traded on that particular day.
The company’s rise was powered by the iPhone, which launched in 2007 and became the center of a broader ecosystem of apps, services, computers, tablets, and accessories. Strong customer loyalty and high-margin services helped make Apple one of the most valuable companies in global markets.
The wording “in the United States” can cause confusion because companies in other countries also reached trillion-dollar valuations. Apple’s record is usually described as the first public-company trillion-dollar milestone overall.
