Rental car company Hertz’s order of 100,000 Teslas pushed the electric car maker into an elite group of public companies worth more than $1 trillion.

Five other U.S. companies have reached $1 trillion valuations — Amazon, Apple, Facebook, Google and Microsoft.

Apple became the first U.S. public company with a trillion-dollar market value on August 2, 2018, following a strong earnings report.

A public company’s value is measured by its market capitalization.
