It’s simply historic. Elon Musk has once again seen his fortune skyrocket. By earning $62.8 billion in just one day, the entrepreneur now sits on assets of $447 billion. He becomes the first individual to cross the dizzying threshold of 400 billion dollars.
SpaceX’s valuation explodes
A colossal increase which is explained, in part, by the valuation of SpaceX, its space company. A recent share buyback has in fact set the value of the startup at $350 billion, compared to $180 billion about a year ago.. It is now the most valuable private company in the world, and even surpasses listed monsters like LVMH, Samsung or Toyota.
This increase is not due to chance. A fervent supporter of Donald Trump, Elon Musk will hold a ministerial role in the president-elect’s administration. With SpaceX’s revenues relying heavily on government contracts awarded by NASA, there is no doubt that the company will benefit in the years to come, especially since it is Jared Isaacman, billionaire and friend of Musk, who will lead the space agency.
Tesla panics the counters on the stock market
At the same time, Tesla’s stock price, which constitutes the largest part of Elon Musk’s fortune, continues to explode. This Wednesday, December 11, it reached the record figure of 424.7 dollars, its highest level since its IPO. The capitalization of the electric car manufacturer exceeds 1,000 billion dollarsand continues to be on the rise since the election of Donald Trump.
But Elon Musk’s fortune is also rising thanks to xAI, his young startup specializing in generative artificial intelligence (AI). It is now worth an estimated $50 billion, while it operates the world’s largest supercomputer.

The first person to reach $1 trillion in personal wealth?
The entrepreneur’s empire does not end there. His stake in X, formerly Twitter, is valued at $11.6 billion. The Boring Company, specializing in tunnels and infrastructure, also contributes to his fortune with a value of $5.7 billion.
Aside from his many businesses, which stand to benefit from a favorable regulatory environment under President Donald Trump, Musk has nearly $6 billion in cash and various investments, according to Forbes.
A recent study showed that the businessman was on track to become the first person to exceed $1,000 billion in personal wealth. It could even reach this incredible milestone as early as 2027.
