Tesla reached a $1 trillion market capitalization in October 2021.
Tesla crossed the milestone on October 25, 2021, after the car-rental company Hertz announced an order for 100,000 electric vehicles. The announcement increased investor enthusiasm about electric-car adoption and Tesla’s position in the expanding market.
Tesla was founded in 2003 by Martin Eberhard and Marc Tarpenning, with Elon Musk joining as an early major investor and later becoming its chief executive. The company’s Model S, Model 3, Model X, and Model Y helped move electric vehicles from a niche product toward mainstream competition with gasoline-powered cars.
Tesla’s market capitalization reflected expectations about future vehicle sales, battery technology, charging infrastructure, software, and autonomous-driving services. It was not equal to the combined value of all cars Tesla had sold. The stock price remained volatile, so the $1 trillion valuation was a market milestone rather than a permanent classification.
