Which cloud-computing and e-commerce company became the fifth U.S. company to reach a $2 trillion market capitalization?

The story behind the answer

Amazon became the fifth U.S. company to reach a $2 trillion market capitalization.

Amazon crossed $2 trillion in July 2024 as investors valued growth in online retail, advertising, and Amazon Web Services. AWS is Amazon’s cloud-computing division and supplies computing, storage, and database services to businesses, governments, and developers.

Jeff Bezos founded Amazon in 1994, and the company began as an online bookseller. It expanded into many product categories before building a large logistics network and cloud business. The combination of retail scale and higher-margin services helped change how investors assessed the company.

Amazon’s $2 trillion valuation came after Apple, Microsoft, Alphabet, and Nvidia had already reached that level. Market capitalization is not a measure of the value of goods held in warehouses or the company’s annual sales; it is the stock-market value of its outstanding equity.
