Apple became the first public company valued at US$3 trillion.
Apple briefly reached a US$3 trillion market capitalization during intraday trading on January 3, 2022. The valuation was calculated from the company's share price and roughly 16 billion outstanding shares. Its market value later crossed that level again on a closing basis in 2023.
The milestone followed years of expansion beyond the iPhone. Apple's services business, wearables such as the Apple Watch and AirPods, and a large installed base of devices helped investors view the company as more than a single-product manufacturer.
Market-cap records are different from annual revenue records or the value of a private company. They also depend on whether a report uses an intraday price or the official closing price. That distinction explains why different dates may be cited for Apple's first passage through the three-trillion-dollar threshold.
