Elon Musk has lost approximately $513 billion in net worth over the past 53 days, a decline roughly equal to the combined fortunes of Google co-founder Larry Page and Amazon founder Jeff Bezos, according to market commentary from Bull Theory. The drop has been driven by a sharp reversal in both of Musk's most valuable holdings — SpaceX and Tesla — after a stretch that briefly made him the world's first trillionaire.
According to Fortune, Musk's fortune peaked at roughly $1.33 trillion on June 16, shortly after SpaceX's stock market debut, before sliding to around $684 billion — a level that leaves him poorer than he was before SpaceX's initial public offering priced just weeks earlier.
A Trillion-Dollar Round Trip
SpaceX shares have fallen roughly 41% to 45% over the past month, erasing more than $1 trillion in market capitalization from a company that had been one of the most anticipated listings in years. An aborted Starship launch during the same stretch added fresh pressure, accelerating a slide that had already wiped out much of the post-IPO enthusiasm.
Tesla's Own Rough Patch
Tesla hasn't provided any offsetting stability. The automaker's worst intraday selloff in more than a year cut roughly $18 billion from Musk's net worth in a single session, following an earnings report that fell short of Wall Street's expectations. Combined with the SpaceX slide, the two companies have driven one of the fastest wealth reversals of Musk's career.

Why the Swing Matters Beyond Musk
Net worth swings of this size are a rough proxy for how quickly sentiment can turn on companies riding the current AI and space-infrastructure enthusiasm. Musk going from trillionaire to below his pre-IPO wealth level in under two months is a reminder that the same optimism fueling aggressive price targets on SpaceX can unwind just as fast once execution stumbles — a dynamic worth watching for anyone pricing in continued momentum from here.
