Elon Musk has lost nearly $90 billion of his fortune in less than two months, causing his net worth to fall below $400 billion for the first time in 2025.
According to Bloomberg’s Billionaire Index, Musk reached his peak wealth in December 2024, becoming the first person to achieve a net worth of $400 billion.
This impressive figure continued to grow until December 17, when his wealth peaked at $486.4 billion, driven by SpaceX’s valuation of $350 billion. But what happened to his wealth?
Why did Elon Musk’s net worth drop?
Musk’s net worth has declined due to the drop in Tesla’s stock price, which has fallen by 27% in less than two months. Tesla experienced its first year-over-year sales loss in more than 12 years, selling 20,000 fewer vehicles in 2024 compared to the previous year.
Additionally, he faces competition from Chinese manufacturer BYD, which has improved its autonomous driving technology with artificial intelligence, a feature Tesla has promised but has yet to deliver, partly due to regulatory difficulties.
2025 has not been favorable for Musk’s electric vehicle company, as Tesla registrations dropped by 63% last month in France, the second-largest electric vehicle market in the European Union. Sales also suffered a 60% decline in Germany.

Where does Elon Musk’s fortune come from?
In 2024, Elon Musk’s wealth remained strongly linked to his stake in Tesla, the global leader in electric vehicles. Musk owns about 13% of the company’s shares, though this percentage may vary depending on fluctuations in sales and the stock market. In 2024, Tesla’s market capitalization exceeded $900 billion, solidifying its position as one of the world’s most valuable companies.
Additionally, Musk owns SpaceX, a private space transport company that plays a key role in his wealth. While SpaceX is privately held, its estimated value at the end of 2024 was over $150 billion.
Musk owns approximately 44% of SpaceX, and its technological innovations (such as Mars exploration and reusable rockets) have attracted significant investments. The company generates substantial revenue through contracts with NASA and commercial partnerships with other businesses, including satellite launches and private space missions.

- The Boring Company: Also founded in 2016, this company focuses on building tunnels to improve urban traffic with underground transportation systems. Currently, The Boring Company is valued at around $6 billion.
Moreover, Musk has invested in various startups and emerging tech projects, ranging from artificial intelligence to advanced battery technologies, such as Thud, a media company, and SolarCity, a company that merged with Tesla in 2016.
