Tesla crossed a $1 trillion market capitalization in October 2021 after its shares surged during a major vehicle-order announcement.
Tesla passed the threshold on October 25, 2021. The share-price jump followed news that Hertz had ordered 100,000 electric vehicles, although the details and timing of deliveries were later discussed extensively. Tesla became one of the first automakers to receive a trillion-dollar valuation from public investors.
The company’s market value reflected expectations about electric-vehicle growth, battery technology, charging infrastructure, software, and possible expansion beyond vehicle sales. Tesla’s valuation was far above that of most traditional automakers at the time, which made it a frequent subject of market-cap comparisons.
Tesla’s stock price has also undergone splits, so historical per-share prices must be adjusted when comparing different dates. A split changes the number of shares and the price per share but does not, by itself, change market capitalization.
