Amazon reached a US$1 trillion market capitalization in September 2018, becoming the second U.S. company to do so after Apple.
Amazon’s shares passed the threshold on September 4, 2018, when the company’s stock price rose above the level needed to value all outstanding shares at more than US$1 trillion. The milestone came as investors continued to reward Amazon’s expansion beyond online retail.
Its businesses included Amazon Web Services, the company’s highly profitable cloud-computing division, along with advertising, logistics, digital media, and subscription services such as Prime. These activities helped broaden Amazon’s financial profile beyond traditional e-commerce.
Amazon’s milestone is distinct from Apple’s earlier 2018 achievement. Alphabet, Microsoft, and other technology companies later joined the trillion-dollar group, but Amazon was the second U.S. company to cross that valuation threshold.
