Elon Musk's net worth hits $681 billion, more than double Google co-founder Larry Page's $249 billion wealth, as Tesla's stock surge widens the billionaire gap.

Tesla CEO Elon Musk is the first person with a net worth of more than $600 billion. His net worth could top $1 trillion when SpaceX goes public next year.

“Elon Musk is now personally worth 7,400,000 BTC,” Burnett wrote, adding, “The fastest way for Elon to hit $1 trillion would be to begin buying BTC in size. And he can continue using that capital as collateral to build space and AI companies, while the collateral continues to appreciate measured in USD.”

SpaceX's reported pursuit of a $1.5 trillion valuation in an IPO next year would add hundreds of billions of dollars to Elon Musk's wealth.

Tesla CEO Elon Musk became the first person to cross the $700 billion mark in net worth on Friday, after the Delaware Supreme Court reinstated Tesla stock options worth $139 billion that had been voided last year, according to Forbes’ Billionaires Index.
