According to Forbes, Musk’s net worth climbed to around $677 billion on Monday, December 16. The sharp increase was driven primarily by a new valuation of SpaceX through a recent tender offer.
The tender offer reportedly values SpaceX at approximately $800 billion, nearly double its valuation from August this year. Musk owns about 42% of the company, resulting in a one-day increase of roughly $168 billion to his personal wealth.

No other individual has previously crossed even the $500 billion threshold, making Musk’s achievement unprecedented. The scale of the increase highlights the growing investor confidence in SpaceX’s long-term prospects.
Reports suggest SpaceX is targeting an initial public offering in 2026, with expectations that the company could be valued at up to $1.5 trillion. Such a move would potentially make Musk the world’s first trillionaire.
SpaceX has now become Musk’s most valuable asset, with Forbes estimating his stake at $336 billion. This surpasses his holdings in Tesla, where his 12% stake is valued at around $197 billion.
Musk also owns a significant share in artificial intelligence firm xAI Holdings, which is reportedly in talks to raise funds at a valuation of $230 billion. Together, these assets have accelerated his rapid wealth accumulation.
