Elon Musk's net worth crossed $1 trillion（約160兆円） after SpaceX's public listing, making him wealthier than the world's next four richest people combined.

What happened: Elon Musk's net worth passed the $1 trillion（約160兆円） mark following SpaceX's initial public offering. His wealth includes 4.8 billion shares in SpaceX, valued after the company's shares opened at $150 and remained well above the $138 benchmark needed to reach a 13-figure net worth, plus his holdings in Tesla and other companies.

Why it matters: Musk now holds roughly as much wealth as Larry Page, Sergey Brin, Jeff Bezos, and Larry Ellison combined—who together are worth just over $1 trillion（約160兆円） according to Forbes. This milestone comes 110 years after John D. Rockefeller became the world's first billionaire in 1916, underscoring the extraordinary concentration of wealth in the modern economy.

What to watch: SpaceX stated in its S-1 filing that the combination of Musk's rocket, AI, and social media platforms positions the company to deliver on "orbital AI compute" by placing AI data center servers in space via reusable rockets—a plan that will be central to the company's growth trajectory.
