Elon Musk, the world's richest person, could become the first trillionaire in history if SpaceX's planned IPO is successful. Musk's net worth is estimated at $273 billion, mainly from his Tesla stock and options. If SpaceX's valuation reaches $1.77 trillion, Musk's stake alone could be worth $841 billion, taking his total fortune to $1.11 trillion.
His wealth would surpass the economies of most countries, including Taiwan, Ireland, and South Africa. It would also exceed the value of all residential and commercial property in Houston, Texas, and the total amount Americans spent buying new vehicles in 2025.
The combined wealth of tech billionaires Larry Page, Sergey Brin, Larry Ellison, and Jeff Bezos would still be below Musk's projected $1.1 trillion fortune. The SpaceX IPO is expected to be listed on the Nasdaq exchange and could become one of the largest stock market listings ever.
