Mumbai.The world’s richest man Elon Musk has crossed the $600 billion net worth mark, becoming the first individual globally to reach this level of wealth. His fortune surged sharply after SpaceX’s internal share sale pegged the private space company’s valuation at $800 billion. Within a single day, Musk’s wealth jumped by nearly $168 billion, an amount almost equal to the combined net worth of India’s two richest businessmen, Mukesh Ambani and Gautam Adani. Musk’s total net worth is now estimated at around $638 billion, or roughly Rs 58 lakh crore.
SpaceX valuation triggers massive wealth surge
The sudden spike in Musk’s fortune is directly linked to SpaceX’s revised valuation. According to Reuters, an insider share sale within the company valued SpaceX at $800 billion, making it the world’s most valuable private company. Musk owns around 42 percent of SpaceX. At this valuation, his stake alone carries enormous weight in his overall wealth calculation. Reports of a potential IPO have further boosted investor expectations around Musk’s holdings.
If SpaceX eventually lists in the US markets at this valuation, Musk’s wealth could rise further. Forbes estimates that under favourable market conditions, Musk could even become the world’s first trillionaire, though this would depend on the IPO’s pricing and listing performance.
How SpaceX valuation translates into wealth
Musk’s SpaceX stake has become the single biggest contributor to his net worth. Key points include:
- SpaceX valuation estimated at $800 billion after insider share sale
- Musk holds around 42 percent equity in the company
- Value of Musk’s SpaceX stake exceeds $336 billion at current estimates
- SpaceX is now the world’s most valuable private company
- IPO speculation has amplified Musk’s paper wealth
Tesla and xAI add further momentum
Apart from SpaceX, Musk’s wealth has also been supported by gains in Tesla and growing interest in his AI venture, xAI. Musk owns around 12 percent of Tesla. In 2025 so far, Tesla shares have risen by nearly 13 percent. On Monday alone, the stock jumped around 4 percent after Musk said the company was testing robotaxis without a safety monitor in the front passenger seat.
Key contributors from Musk’s other businesses include:
- Tesla stake valued at around $197 billion
- Tesla shares up 13 percent so far this year
- xAI in talks to raise $15 billion in new equity
- xAI valuation estimated at around $230 billion
Early life and first business steps
Musk’s journey began early. He learned computer programming at the age of 10 and created a video game called Blaster at 12, which he sold to a local magazine for $500. In 1995, he co-founded web software company Zip2, which was acquired by Compaq in 1999 for $307 million. Musk earned $22 million from the deal for his 7 percent stake, marking the real start of his business career.
PayPal exit and creation of tech empires
Musk went on to found X.com, which later became PayPal. In 2002, eBay acquired PayPal for $1.5 billion, earning Musk about $180 million. Soon after, he founded SpaceX with the aim of reducing space launch costs and making humans a multi-planetary species. Over time, he also built Tesla into a global electric vehicle leader and launched Neuralink in 2016 to develop brain-machine interface technology.
Today, Musk’s wealth story reflects the combined impact of SpaceX, Tesla, AI ambitions and a career defined by high-risk, high-reward innovation.
