Apple became the first U.S. company to reach a $1 trillion market capitalization in 2018. Its share price crossed the threshold on August 2, 2018, when the company’s outstanding shares valued it at approximately $1 trillion.
The milestone reflected Apple’s enormous scale in consumer technology, especially through the iPhone, which had become the company’s dominant product and a major global computing platform. Apple had previously become the world’s most valuable publicly traded company by market capitalization in 2011.
Saudi Aramco later became the first company to exceed a $2 trillion valuation, although the exact market-cap ranking of companies changes with share prices. Apple’s $1 trillion milestone is therefore a historical event, not a permanent ranking.
People sometimes confuse Apple’s $1 trillion achievement with its later $2 trillion and $3 trillion milestones. Apple reached approximately $2 trillion in 2020 and briefly passed $3 trillion in 2022.
