Tesla exceeded a US$1 trillion market capitalization for the first time on October 25, 2021. Its shares jumped after rental-car company Hertz announced an order for 100,000 Tesla vehicles, although the valuation reflected broad investor expectations as well as that single deal.
Tesla was the first automaker to join the trillion-dollar market-cap group. Investors valued its electric-vehicle growth, battery technology, software features, charging network, and potential expansion into energy products and autonomous driving.
The company’s valuation was far above the market values of most traditional automakers, which produced vehicles in much larger historical volumes. Tesla’s supporters emphasized future growth, while critics argued that the stock price assumed very ambitious outcomes.
Market capitalization is not the same as enterprise value or annual sales. Tesla’s share price later moved sharply in both directions, showing that the trillion-dollar mark was a changing market assessment.
