Tesla became the first automaker valued at more than $1 trillion in 2021.
Tesla’s market capitalization surpassed the $1 trillion threshold in October 2021 after its share price rose sharply. Market capitalization is calculated by multiplying a company’s share price by its outstanding shares, so the milestone reflected investors’ valuation of Tesla rather than the company’s cash holdings or annual sales.
The rise followed strong investor enthusiasm for electric vehicles, Tesla’s expanding production, and a major vehicle order from Hertz announced in October 2021. Tesla was already the world’s most valuable automaker by market capitalization before crossing the trillion-dollar mark.
This milestone is often mixed up with company revenue, profit, or physical production. It measured stock-market value, which can change daily, rather than a permanent accounting category. Tesla later moved above and below the threshold as its share price fluctuated.
