Apple was the first company to exceed a $1 trillion market capitalization on a U.S. stock exchange.
Apple crossed the threshold on August 2, 2018, when its share price rose after the company reported strong quarterly results. The milestone was based on the number of shares outstanding and the market price, rather than on a single cash payment or a government valuation.
Apple’s path to the milestone was powered first by the iPod and then by the iPhone, which became the company’s main growth engine after its 2007 launch. Revenue from services, wearables, and accessories later broadened Apple’s business beyond hardware.
The wording matters because several companies reached $1 trillion around the same period. Amazon followed later in September 2018, while Microsoft had previously approached the level during the dot-com era but did not become the first company to cross it under the modern milestone commonly cited for U.S. public companies.
