Elon Musk has lost his trillionaire status, reportedly due to a decline in the value of his companies, including SpaceX. The loss is attributed to a global tech rout and a sell-off that erased billions from his fortune. However, there is some inconsistency in the reports, with some outlets previously suggesting Musk's net worth had reached trillionaire status, while others now confirm its loss, amidst a broader decline in tech stocks.
