Tesla became the first electric-car maker to reach a $1 trillion market capitalization in October 2021.
Tesla’s valuation crossed $1 trillion on October 25, 2021, after rental-car company Hertz announced an order for 100,000 electric vehicles. The announcement intensified investor optimism about Tesla’s production growth and its position in the expanding electric-vehicle market.
Tesla’s market value was exceptionally large compared with its vehicle deliveries at the time, which prompted debate about whether its valuation reflected future growth rather than current sales alone. The company had become a major producer of battery-electric vehicles through models such as the Model 3 and Model Y. Tesla’s milestone is distinct from being the world’s largest automaker by unit sales or revenue; market capitalization measures the value investors assign to a company’s shares.
