Elon Musk just became the world’s first trillionaire.

With SpaceX opening on the Nasdaq at $150 a share Friday, his stake in the company is worth more than $766 billion. Combined with his Tesla stake, which is worth $280 billion, Musk’s net worth from both companies as of Friday is roughly $1.05 trillion.

The SpaceX IPO added more than $180 billion to Musk’s fortune. He’s now worth more than the next five richest billionaires in the world combined. His personal net worth is larger than the national GDPs of Taiwan, Ireland or Sweden.

Musk’s coronation as the first person in history to be worth $1 trillion is likely to add fuel to the debate over wealth inequality and the rise in power of America’s richest tech founders. Along with creating the world’s first trillionaire, the SpaceX IPO also minted thousands of new millionaires and several new billionaires among the employees and executives who own stock.

Shares of SpaceX were trading about 20% higher shortly after their official debut, at around $164 apiece. That values the company at roughly $2 trillion.

Shares of Tesla were down about 1% midday Friday at roughly $395 apiece.
