Amazon was the first company to reach a $1 trillion market capitalization while its pre-split stock price exceeded $1,000 per share.
Amazon crossed the $1 trillion market-capitalization level on September 4, 2018, about a month after Apple achieved the broader first. At that time, Amazon’s shares traded above $2,000, so the company’s huge valuation came from both a high share price and a very large number of shares outstanding.
Amazon began in 1994 as an online bookstore founded by Jeff Bezos. It expanded into a broad e-commerce marketplace, logistics network, digital media business, and cloud-computing provider through Amazon Web Services. AWS became a particularly important source of operating profit.
The question uses the pre-split price because Amazon later completed a 20-for-1 stock split in 2022. A split lowers the quoted share price but does not by itself change market capitalization, since the number of shares rises proportionally.
