SpaceX Lost an Entire Tesla's Worth of Market Cap in Just One Month

SpaceX, which remains a privately held company, saw its estimated market valuation plunge by an amount roughly equal to the entire market capitalization of Tesla in just over a month — a striking illustration of valuation volatility at the very top of the private tech world. SpaceX had long been regarded as the undisputed leader of the commercial space race, commanding premium valuations that rivaled or exceeded those of major public companies. The sharp markdown raises questions about the sustainability of the lofty multiples applied to elite private tech firms. The drop also carries indirect implications for Tesla shareholders, given the close association between the two companies through their common founder. Investors should keep in mind that private company valuations lack the daily transparency of public markets and can be revised sharply and suddenly.
