- Elon Musk's slice of SpaceX is worth $43 billion more than his Tesla stake, per Bloomberg.
- Tesla stock has been tumbling since December, reducing the CEO's net worth.
- SpaceX was most recently valued at $350 billion.
The value gap between Elon Musk's stakes in Tesla and SpaceX has widened to $43 billion following the slide in the EV maker's stock.
Musk has a stake of about 42% in SpaceX, according to Bloomberg. The rocket and satellite company was most recently valued at $350 billion, with his stake worth $136 billion taking into account a 5% private company discount.
Musk's 13% stake in Tesla is worth $92.6 billion per Bloomberg's calculations — a difference of $43.4 billion.
His holding in xAI is third, at $22.6 billion, with stakes in X Corp, The Boring Company and Neuralink also contributing to his wealth.
Musk is still firmly atop the Bloomberg Billionaires Index at $303 billion as of Tuesday's close. His net worth has cratered by $130 billion, or 30%, this year largely due to the fall in Tesla stock.
It's down more than 50% from mid-December, wiping some $800 billion from its market cap to just above $700 billion at Tuesday's close. Tesla closed 5% lower on Tuesday.
Musk became the first person to be worth more than $400 billion in December.
Tesla stock surged after Donald Trump won the presidential election in November. Musk had aggressively campaigned for Trump, spending more than $200 million.
However, sliding Tesla sales have unnerved investors, along with criticism of Musk's political interventions with DOGE.
The average price of a used Tesla is now $10,000 less than that of a non-Tesla electric vehicle, Business Insider previously reported based on data from the dealership website CarGurus.
