Elon Musk loses $650 billion in 5 weeks as Tesla and SpaceX plunge

Elon Musk's paper fortune has been cut nearly in half as his two largest holdings — Tesla and SpaceX — suffered simultaneous declines that erased more than $650 billion of wealth in just over a month.

SpaceX's market capitalization fell 41% from its post-IPO peak and Tesla dropped 15% in a single day after a second-quarter earnings miss, vaporizing roughly $650 billion of Elon Musk's paper wealth between June 16 and July 23.

"This is two idiosyncratic repricings landing on one balance sheet at the same time," said a portfolio manager who tracks concentrated wealth positions. "The macro backdrop is calm — the VIX closed at 16.64 on July 22 — which makes the scale of the drawdown even more striking."

SpaceX shares closed at $118.24 on July 23, down 41.41% from their June 16 peak of $201.80, cutting the rocket-and-satellite company's market cap from $2.64 trillion to $895 billion. Tesla fell 14.52% to $319.69 after reporting Q2 non-GAAP EPS of $0.33 against a $0.5367 consensus — a 38.51% miss — while operating income collapsed 56.88% year-over-year to $398 million and free cash flow swung to negative $1.09 billion.

Musk's peak wealth of $1.45 trillion on June 16 has shrunk to roughly $738 billion, according to the Bloomberg Billionaires Index. The next catalyst is SpaceX's looming lockup expiration — larger than the entire IPO float — which could flood the market with shares and extend losses further.

SpaceX's $1.7 Trillion Round Trip

SpaceX's June 12 IPO was the largest in history, and shares surged to $201.80 within days, pushing the company past a $2.6 trillion valuation. The reversal was swift. A delayed Starship launch on July 16 hit the stock in extended trading. Post-IPO enthusiasm faded. A broader reappraisal of AI-linked valuations rolled through the tape. By July 21, SPCX had briefly traded below $120, dipping under its IPO price after seven consecutive down sessions. Short sellers have booked an estimated $15.5 billion in profit on the slide, according to retail trading forum data.

Tesla's Margin Squeeze

Tesla's Q2 revenue of $28.24 billion beat estimates by 7.10%, and deliveries hit a record 480,126. The problem sat below the top line. Operating margin compressed to 1.4% from roughly 5% a year earlier as operating expenses surged 47% year-over-year to $4.35 billion, driven by spending on AI, robotaxi development, the Optimus humanoid robot, and stock-based compensation tied to Musk's 2025 CEO Performance Award. Capital expenditures jumped 141.81% to $5.79 billion, pushing free cash flow to negative $1.09 billion. Shares are now down 28.91% year to date.

Musk's headline number is a mark-to-market figure, not a realized loss — neither his TSLA nor SPCX stakes have been sold. The signals to watch over the next quarter are specific. On Tesla: whether Q3 operating margin recovers off the 1.4% floor and whether capex guidance holds near the $25 billion analyst figure. On SpaceX: the lockup calendar and the next Starship attempt. If those go badly, the $650 billion number gets larger. If they go well, it shrinks fast.
