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.
