Musk tops $500B as world’s 10 richest control combined $2.3T

As of October 1, 2025, Elon Musk has become the first person in history to reach a net worth of $500 billion, driven largely by a 33% surge in Tesla shares, investor enthusiasm around AI and robotics, and his $1 billion stock purchase. Musk’s wealth is also bolstered by his aerospace company SpaceX, now valued at $400 billion, and his AI startup xAI, valued at $80 billion following a $6 billion private funding round. Tesla remains central to his fortune with a market valuation exceeding $1 trillion. Musk has held the title of the world’s richest person multiple times since 2021, most recently reclaiming it in May 2024. Larry Ellison, co-founder and executive chairman of Oracle, ranks second with an estimated net worth of about $350.7 billion. Oracle’s stock jumped 36% in September 2025 after the company projected a 700% revenue increase in its cloud infrastructure business over four years,
