The Numbers Come First
Elon Musk's net worth peaked at approximately $1.33 trillion on June 16, according to the Bloomberg Billionaires Index. It now stands at $684 billion — a decline of more than $600 billion in just over a month. Bloomberg notes that drop exceeds the total net worth of any other individual ever ranked among the world's 500 richest people, save Musk himself.
The primary driver is SpaceX. Shares of Space Exploration Technologies Corp. hit a closing high of $201.80 on June 16 and have since tumbled 46% to a record low of $108.37. Musk's SpaceX position is currently valued at more than $550 billion, per Bloomberg's wealth index.
The Short-Seller Pile-On
The selloff has attracted aggressive short interest. According to S3 Partners, short interest in SpaceX rose to 219.3 million shares as of July 29, up sharply from 23.3 million on June 16 — representing more than one-third of shares available for public trading. The pressure may not ease soon: as many as 911.5 million shares belonging to insiders and early backers are set to unlock next month, a potential additional overhang on price. SpaceX is scheduled to report its first quarterly earnings as a public company next week.
Tesla Compounds the Pain
Tesla has added to Musk's losses. Shares of the Austin-based carmaker have fallen 17% since the company released second-quarter results on July 22. Tesla reported $5.8 billion in capital expenditures for the quarter — what Musk himself called 'a massive capex year' — and recorded its first cash-negative quarter in two years. The company said it expects to spend more than $25 billion on capital expenditures for the full year, funding a pipeline that includes Optimus humanoid robots, autonomous Cybercabs and AI initiatives. Tesla shares are now down 36% from their December high. Musk holds Tesla stock valued at $129 billion, according to Bloomberg.
The cash burn overshadowed better-than-expected car deliveries and higher revenues, a sign that investors are discounting near-term fundamentals in favor of scrutinizing the capital allocation story.
CEO Times View
The market has already voted, and the verdict is a reminder that gravity applies even to trillion-dollar fortunes. The SpaceX IPO unlocked enormous paper wealth in June; the subsequent rout reflects what always happens when price discovery meets a float dominated by locked-up insider shares and a short-seller community that smells an overhang. That is not a policy failure — it is free markets functioning exactly as designed.
What investors are really pricing is execution risk at scale. Tesla's $25 billion capex commitment is a bet on robotics and autonomous vehicles that could reshape American manufacturing or drain the balance sheet into the next cycle. Capital rewards clear rules and visible returns. Until SpaceX's first earnings report lands and Tesla demonstrates a credible path from capex to cash flow, the market will keep discounting the vision — no matter how spectacular the Starship launch looked from Starbase.
