Per data from Arkham, the latest decline leaves him just $3 billion short of reclaiming the milestone, stirring curiosity about the reason behind the drop this time.
Last month, Elon Musk became the world's first trillionaire after SpaceX's record-breaking IPO sent his net worth above $1 trillion. The trend continued, with his fortune soaring to nearly $1.45 trillion as SpaceX shares surged to record highs.
With SpaceX valued at $715 billion, the company makes up the largest share of Musk's wealth. Thus, the trillion-dollar milestone being short-lived has been largely attributed to SpaceX's performance.
SpaceX sees major decline
It is important to note that the latest drop in Musk's net worth has coincided with a recent decline in the stock price of SpaceX.
The stock has fallen below its $135 IPO price after reaching more than $200 in the weeks following its record-breaking launch on Nasdaq.
While SpaceX accounts for about $715 billion of Musk's currently estimated $997 billion net worth, it is expected that even small declines in the company's share price can add or remove billions of dollars from his net worth.
