Which company became the first publicly traded company valued at $1 trillion in 2018?

The story behind the answer

Apple became the first publicly traded company valued at $1 trillion in 2018.

Apple crossed the landmark valuation in August 2018 after its share price rose following strong financial results and investor confidence in its hardware-and-services ecosystem. The company’s outstanding shares multiplied by the market price produced the trillion-dollar figure.

The achievement was significant because it demonstrated how a consumer electronics company could grow into one of the world’s largest economic entities. Apple’s iPhone remained its best-known product, while the App Store, cloud services, subscriptions, and accessories added recurring revenue.

Amazon, Microsoft, and Alphabet reached the same threshold later. Some accounts distinguish between briefly touching a valuation during trading and closing above it, so wording about the exact moment matters when comparing market-cap records.
