Elon Musk, the billionaire entrepreneur behind Tesla, SpaceX, and X Corp., has made history as the first individual to achieve a net worth of $500 billion, according to Forbes’ Real-Time Billionaires tracker.
Musk’s wealth has surged past this unprecedented milestone, placing him $150 billion ahead of runner-up Larry Ellison, and positioning him as a likely candidate to become the world’s first trillionaire in the coming years.
The South Africa-born innovator owes much of his fortune to his holdings in Tesla, where he owned more than 12.4% of the company as of September 15. Tesla’s stock has seen a remarkable 14% increase this year, with Wednesday’s trading alone adding over $6 billion to Musk’s net worth.
But Tesla is not the only driver of Musk’s historic wealth. His ventures in artificial intelligence and space exploration, including xAI and SpaceX, have also contributed significantly. xAI was valued at $75 billion as of July 2025, while SpaceX’s valuation reportedly reached $400 billion during recent fundraising discussions.
Musk’s focus on advancing AI and robotics within Tesla has further boosted investor confidence. Recently, he purchased about $1 billion worth of Tesla shares, signaling strong faith in the company’s future. In addition, Tesla’s board proposed a $1 trillion compensation plan for Musk, contingent upon achieving strategic company goals.
After a challenging start to the year, Tesla shares have rebounded steadily, driven in part by Musk resuming a more active role in operations. Robyn Denholm, Tesla’s board chair, noted that Musk was now “front and centre” at the company following his brief advisory tenure at the White House.
Musk’s milestone highlights the extraordinary growth of tech billionaires in the 21st century and underscores the massive impact of AI, electric vehicles, and space ventures on personal wealth accumulation.
As the world watches, Elon Musk continues to push technological frontiers while setting unprecedented records in wealth creation, cementing his status as one of the most influential figures of the modern era.
