Elon Musk has officially shattered every financial record in human history. As of late October 2025, the entrepreneur, inventor, and provocateur has become the first individual to cross the once-unimaginable threshold of $500 billion in personal net worth , according to Forbes’ Real-Time Billionaires list. The milestone, reached on October 1 and solidified in the weeks that followed, marks not just a personal triumph for Musk but a symbolic turning point in the concentration of global wealth, the explosive growth of technology sectors, and the volatile intersection of business and politics.
The Numbers Behind the Milestone
Forbes pegged Musk’s fortune at exactly $500 billion on October 28, 2025—the most precise and up-to-date valuation available. The figure reflects real-time fluctuations in the stock prices of his flagship companies, primarily Tesla , SpaceX , and the newly merged xAI Holdings (which absorbed X, the social media platform formerly known as Twitter, in a blockbuster March 2025 deal).
Here’s how the wealth breaks down:
- Tesla: Musk owns approximately 19.7% of the electric vehicle giant. With Tesla’s market capitalization soaring past $1 trillion again in late 2025—fueled by record quarterly deliveries, the long-awaited Robotaxi unveil, and a surprise surge in energy storage revenue—this stake alone accounts for the lion’s share of his fortune.
- SpaceX: Valued at $400 billion following an August 2025 tender offer, the aerospace leader continues to dominate the commercial space industry. Musk’s 42% ownership translates into a personal holding worth roughly $168 billion a figure that would make SpaceX alone one of the most valuable private companies ever.
- xAI Holdings: After merging X (the social platform) with his artificial intelligence startup xAI in March 2025, the combined entity was valued at $113 billion. Musk retains a 53% stake, contributing another $60 billion to his balance sheet.
Smaller holdings in Neuralink, The Boring Company, and various venture investments round out the portfolio, but the “big three”—Tesla, SpaceX, and xAI—remain the gravitational centers of his wealth.
From $400 Billion Peak to $126 Billion Crash—and Back Again
Musk’s journey to half a trillion wasn’t linear. In December 2024, he briefly touched $400 billion, riding the twin waves of Tesla’s post-election stock rally and SpaceX’s successful Starship orbital flights. But 2025 began with turbulence.
A $126 billion wipeout in early 2025 followed intense political backlash. Musk’s high-profile role co-chairing the U.S. Department of Government Efficiency (DOGE)—a Trump administration initiative aimed at slashing federal spending—drew fierce criticism from progressive lawmakers, labor unions, and even some Tesla shareholders who feared brand damage. Tesla’s stock dipped below $200 per share in February, dragging Musk’s net worth down with it.
The turning point came in September 2025. Musk announced he would step back from DOGE to refocus on Tesla and xAI, a move framed as both strategic and conciliatory. Investors responded with euphoria. Tesla shares nearly doubled in three weeks, pushing the company’s market cap back above $1 trillion and catapulting Musk past $500 billion for the first time on October 1, 2025.
