Which company became the first publicly traded business to close a trading day valued at $3 trillion?

The story behind the answer

Apple became the first publicly traded business to close a trading day valued at $3 trillion.

Apple achieved the closing milestone on June 30, 2023, after its share price finished above the level needed for its outstanding shares to total $3 trillion in market value. This was different from Apple’s earlier January 2022 achievement, when it only touched the threshold during intraday trading.

Closing market capitalization is widely used for historical comparisons because it is based on the official end-of-day share price. Intraday valuations can be temporary and may disappear before the market closes.

Apple’s growth has combined hardware sales with recurring income from services, accessories, and digital platforms. Its market value has also been affected by stock splits, which change the quoted price per share without changing the company’s overall valuation at the moment of the split.
