Overview

• Elon Musk became the first person to top $500 billion in estimated wealth on Forbes’ real‑time tracker on Oct. 1 before slipping to $499.1 billion shortly after.
• Bloomberg put Musk’s wealth at roughly $470 billion the same day, underscoring divergent methodologies and uncertainty around private holdings.
• A roughly 4% rise in Tesla’s share price drove an estimated $9 billion one‑day increase in Musk’s net worth.
• Forbes attributes about $191 billion to Musk’s roughly 12% Tesla stake and values his 42% SpaceX holding near $168 billion, with additional value from xAI/X and other ventures.
• Tesla’s board has proposed a multi‑tranche equity award that could be worth up to about $1 trillion if stringent market‑cap and operational targets are achieved, with shareholders voting in November.
