Billionaire businessman Elon Musk has become the first person in history to reach a net worth of nearly $500 billion, according to Forbes’ Billionaires Index. His fortune, valued at $500.1 billion, is driven primarily by the rebound in Tesla’s stock, which has surged over 14% this year.
Musk owns a 12.4% stake in Tesla, worth billions of dollars. The company’s market capitalization has climbed back to within 10% of its record high from last December. SpaceX, valued at around $400 billion, significantly contributes to Musk’s wealth. Musk owns an estimated 42% stake in the company, worth approximately $168 billion. Musk’s AI startup, xAI, was valued at $75 billion in July. His 53% ownership stake gives him an additional $60 billion in personal wealth.
Musk’s wealth growth has been rapid, crossing significant milestones:
• $100 billion: Musk entered the $100 billion club in August 2020
• $200 billion: He crossed $200 billion in September 2021
• $300 billion: Musk reached $300 billion in November 2021
• $400 billion: He became the first person to hit $400 billion in December 2024
• $500 billion: Musk’s net worth reached $500.1 billion on October 1, 2025
With his current trajectory, experts project Musk could become the world’s first trillionaire by March 2033, aligning with the first vesting date of his $1 trillion Tesla pay package.
