Biography
Elon Musk cofounded seven companies, including electric car maker Tesla, rocket producer SpaceX and artificial intelligence startup xAI.
He owns about 12% of Tesla, which he first backed in 2004, and which he's led as CEO since 2008. He also owns options to acquire another 8%.
Musk led a group that bought Twitter for $44 billion in 2022. He merged it with xAI in 2025 in deal that valued the combined company at $113 billion (net of debt).
SpaceX, founded in 2002, acquired xAI in February 2026 in a deal that valued the combined company at $1.25 trillion. Musk owns a nearly 40% stake.
Musk also founded tunneling startup The Boring Company and brain implant outfit Neuralink. The two startups have raised around $2 billion from private investors combined.
Perspective on their fortune
Gold
Everyday luxury

A Elon Musk's fortune is equivalent to 5498 of gold, but this may be difficult to value, as we don't usually have a handful of gold bars in our piggy bank.

A standard gold ring typically weighs between 4 and 7 grams. Let's say this one weighs 5 grams. It's usually 18k gold.
Based on today's gold price (not taking into account the jeweler's fee, shipping, or anything else), that gold ring would be worth $556.3
Elon Musk could buy 1,466,131,416 gold rings. That's a lot of fingers and a lot of gifts!!
And if the number of rings is difficult to visualize, all these rings would need 262 trucks to transport them, But we can be almost certain that Elon Musk will have enough left over to pay for the gas for those trucks.
Health
The price of life
Let's compare Elon Musk's fortune with the healthcare spending of a huge country
Elon Musk could fund the entire healthcare system of DR Congo with a population of over 105,800,000 of inhabitants for approximately 367.1 years.
But even if we compare their fortune to that of a rich country
At the other extreme, Elon Musk could cover the health expenditure of Luxembourg, considered the world's most heavily invested health system, for 162.2 years
Education
Buying the future
Lowest education spending
Elon Musk could assume the entire cost of the education system of Nigeria, the most populous country in Africa, with more than 243,000,000 inhabitants for 239.9 years.
Highest education spending
But not only could he assume the cost of a poor country, Luxembourg is considered the country with the highest per capita investment in education in the world, Elon Musk could pay for it in full for 326.2 years.
Research
The monopoly of progress
Lowest research spending
Elon Musk could fully fund the state research budget of Pakistan, the fifth most populous country in the world with more than 260,000,000 of inhabitants, for 1373.1 years.
Highest research spending
But even if we compare the total wealth of Elon Musk with Israel, the country that currently invests the most per capita in research in the world, it could assume the total cost of the system for 30.8 years.
