Elon Musk's net worth plunges below pre-IPO level after SpaceX share slump

Despite a successful Starship mission from the Starbase site in South Texas, SpaceX’s share price has fallen from a June high of $201.80 to a record low of $108.37, a 46% drop that has cut Elon Musk’s net worth to roughly $684 billion, below his pre-IPO level. The slide is amplified by a rise in short interest to 219.3 million shares and the impending release of 911.5 million insider and early-investor shares, which could add further pressure.

In parallel, Tesla’s stock slipped 17% after reporting its first cash-negative quarter in two years, despite higher revenues and vehicle deliveries. Bloomberg’s Billionaires Index records the $600 billion reduction as the largest single-person decline on its list, leaving Musk’s SpaceX stake at over $550 billion and his Tesla holdings at $129 billion.
