Apple became the first U.S. corporation to exceed $1 trillion in market value during intraday trading in 2018.
Apple passed the threshold during trading on August 2, 2018. The milestone was calculated by multiplying the company’s share price by its outstanding shares, so it could be crossed or lost as the stock moved during the day. Apple’s closing valuation and intraday peak were not necessarily identical.
The achievement followed strong demand for the iPhone and growing contributions from services such as the App Store, Apple Music, and cloud-connected subscriptions. Apple’s hardware, software, and retail ecosystem also encouraged customers to remain within its product family.
This record is often described as the first trillion-dollar company, but wording matters. It refers to a publicly traded company’s market capitalization, not the first business ever estimated to be worth that amount under a private valuation or historical comparison. Later, other technology companies crossed the same threshold.
