Tesla last week joined the handful of companies valued at more than $1 trillion.
The $6 billion amount would be just a small fraction of Musk’s current net worth of $311 billion — and less than the $9.3 billion his wealth increased on Oct. 29 alone, according to Bloomberg’s wealth index.
Tesla forms the vast majority of Musk’s net worth. He’s very rarely sold stock in the EV maker, whose shares reached a record $1,114 on Friday. The shares opened 3.2 percent higher on Monday morning as well.
Musk’s fortune has also surged thanks to his stake in SpaceX, a private space-exploration company that was valued at about $100 billion last month.
Musk, frequently outspoken on social media, has also been critical of attempts to tax U.S. billionaires.
He said on Twitter that a levy on billionaire wealth would only make a “small dent” toward paying off the national debt, arguing that the focus should be on government spending. Musk also said a billionaire tax would just be the start of taxing the merely wealthy.
