Elon Musk has become the first person in history to surpass $600 billion in estimated net worth, a milestone driven by gains at SpaceX and Tesla.
Forbes’ estimate, put Musk’s fortune at about $677 billion after private-market moves that pushed up the value of his 42% stake in SpaceX.
Reuters reported the SpaceX valuation could reach roughly $800 billion if the company goes public — a step that could add about $168 billion to Musk’s wealth.
Tesla shares have also helped lift Musk’s wealth.
The company’s stock jumped after Musk confirmed the firm is testing “driverless robotaxi” technology without safety monitors — news that bolstered investor hopes for future growth in cars and robotics.
Not all trackers show the same figure, however.
The Bloomberg Billionaires Index reported a slightly lower total but still placed Musk at the top of the list, reflecting the daily swings in stock prices and differing methods for valuing private companies.
“Net worth estimates vary because they rely on public stock prices and calculated values for private holdings,” Bloomberg notes.
Any formal SpaceX IPO, further gains at Tesla, or large financing deals for Musk’s AI and robotics ventures could push his reported wealth even higher — but such estimates remain volatile and change with markets.
