Tesla surpassed a $1 trillion market capitalization in October 2021.
Tesla’s shares rose above the threshold on October 25, 2021, after rental-car company Hertz announced an order for 100,000 electric vehicles. The announcement reinforced expectations that electric cars could move into mainstream fleet and consumer markets.
Tesla was unusual among automakers because investors valued it partly as a technology and energy company, not only as a vehicle manufacturer. Its businesses included battery storage, solar products, charging infrastructure, and software features alongside electric cars.
Market capitalization measures the value assigned by shareholders and can be far higher or lower than a company’s annual revenue. Tesla’s trillion-dollar valuation was particularly notable because traditional automakers generally produced far more vehicles at that time, while Tesla’s valuation reflected expectations of future growth.
