Which company became the first public company to reach a $1 trillion market cap during intraday trading?

The story behind the answer

Apple became the first public company to reach a $1 trillion market capitalization during intraday trading.

The milestone occurred on August 2, 2018, when Apple’s shares rose enough for the total value of its outstanding stock to pass $1 trillion. Apple later finished the session above the threshold, making the achievement especially notable in financial-market history.

The calculation used the company’s share price and its number of outstanding shares. It did not mean Apple held one trillion dollars in cash. Market capitalization is an equity valuation, and it can rise or fall without a matching change in the company’s bank balance.

Apple’s achievement followed years of growth in the iPhone business and increasing contributions from services, accessories, and other devices. The company had already become one of the world’s most valuable firms before the round-number record drew broad public attention.
