SpaceX Share Decline Pushes Elon Musk’s Wealth Below $700 Billion

On Monday, SpaceX shares slipped 4.8% to roughly $109.50, extending a 50% plunge that began after the stock’s all-time high on June 16. The drop reduced Elon Musk’s holdings—4.8 billion shares and 350 million stock options—by $29.5 billion, bringing his estimated net worth to $695.7 billion, according to Forbes. An earlier aborted Starship launch on July 16 had already shaved more than $45 billion from his fortune, pushing it below $800 billion at the time. Overall, Musk’s wealth has fallen about $750 billion since its peak of $1.45 trillion on June 16, with roughly $116 billion of that decline attributed to Forbes removing Tesla options after new vesting conditions were agreed upon.

Musk’s net worth crossed the $700 billion mark in December 2025, rose past $800 billion in February, and briefly entered trillion-dollar territory after SpaceX’s initial public offering last month. The recent rout marks the first time his fortune has slipped below $700 billion since December 2025.

JPMorgan analysts warned that the latest Starship launch would invite “plenty of analysis,” noting that investors should expect both progress and setbacks through 2027. Morgan Stanley analysts cautioned that a share price under $100 could signal that investors see little to no value in SpaceX’s AI business, while some market watchers argue the firm’s spending on space, connectivity, and uncertain economics could render its valuation “zero or negative.”

Musk acknowledged the decline on X, referring to himself as a “former” trillionaire. The sustained share weakness not only trims his personal wealth but also raises questions about the market’s confidence in SpaceX’s long-term profitability and its expanding AI ambitions.
