Apple was the first public company to reach a $2 trillion market capitalization in 2020, after Saudi Aramco’s 2019 debut.
Apple crossed $2 trillion on August 19, 2020. The milestone followed its earlier achievement as the first U.S.-listed company to reach $1 trillion in 2018. Apple’s rising value was supported by the iPhone business, recurring services revenue, and investor confidence in its hardware-and-software ecosystem.
The wording matters because Saudi Aramco had already received a valuation near $2 trillion when it listed shares in December 2019. That was an initial-public-offering valuation, while Apple reached the level through the subsequent rise in the market value of an already publicly traded company.
