Elon Musk’s net worth has passed the trillion-dollar mark after SpaceX’s IPO. His net worth, which was hovering around $800 billion before the IPO, includes the value of his 4.8 billion shares in SpaceX, along with his wealth from his other companies, like Tesla. Shares of SPCX opened at $150 and have remained well above the $138 benchmark that gives Musk a 13-figure net worth.

SpaceX combined Musk’s rocket, AI, and social media platforms earlier this year, and said in its S-1 that its goal is to “build the systems and technologies necessary to make life multiplanetary, to understand the true nature of the universe, and to extend the light of consciousness to the stars.” It also claims this combination is uniquely positioned to deliver on the concept of “orbital AI compute” by putting AI data center servers in space via reusable rockets.

Musk is now worth, on paper, roughly as much as the next four wealthiest people in the world combined. According to Forbes, Larry Page, Sergey Brin, Jeff Bezos, and Larry Ellison, all together, are worth just over $1 trillion. Bezos and Ellison each have less than a fourth of Musk’s net worth. Musk passed the $1 trillion mark 110 years after John D. Rockefeller became the world’s first billionaire in 1916.
