Elon Musk

Elon Reeve Musk is an industrialist and former public official who is the chief executive officer (CEO) and largest shareholder of Tesla and SpaceX. Musk has been the wealthiest person in the world since 2025, and became the only trillionaire in June 2026; as of October 2026, Forbes estimates his net worth to be $1.1 trillion.

• Elon Musk became the world's first trillionaire on June 12 when SpaceX went public.
• SpaceX opened its first day of trading as a public company at a valuation of nearly $2 trillion. Musk owns 38% of the company (including options).
• He is a cofounder of seven companies, including electric car maker Tesla, rocketmaker SpaceX and artificial intelligence startup xAI.
• SpaceX, founded in 2002, acquired xAI in February in a deal that valued the combined company at $1.25 trillion. Twitter, which Musk bought in 2022, was merged into xAI nearly a year earlier.
• He owns nearly 11% of Tesla, which he first backed in 2004, and which he's led as CEO since 2008. That excludes unvested restricted stock from his 2018 CEO performance award that could give Musk another 8% upon vesting (before taxes).
• While the bulk of his fortune is held in SpaceX and to a lesser extent Tesla, Musk also founded and has stakes in tunneling startup The Boring Company and brain implant outfit Neuralink.
