After reaching a net worth of more than $486 billion in December, Elon Musk’s wealth has sunk below $400 billion for the first time in 2025. Tesla—where Musk derives about 60% of his wealth—has had an abysmal year. Waning demand and Musk’s continued controversial foray into politics have helped drive the stock down 27%.

Experts say he could easily snuff out federal investigations or safety initiatives that have stymied Tesla or his other companies.
