New York, October 2, 2025 — Elon Musk has officially become the first individual in recorded history to see his personal fortune cross the $500 billion mark, according to Forbes’ Real-Time Billionaires Index. The milestone makes him not only the wealthiest living person, but also the first human to achieve half a trillion dollars in net worth.
Musk’s fortune is tied primarily to his large stakes in Tesla, SpaceX, and his artificial intelligence ventures. The surge in Tesla’s stock price in recent weeks helped propel his net worth past the $500 billion threshold, a level no one else has reached in modern financial records.
Historical Comparisons
While Musk’s achievement is unprecedented in absolute dollar terms, history is filled with figures who commanded immense fortunes in their own time:
• John D. Rockefeller, the American oil magnate of the late 19th and early 20th centuries, is often cited as one of the wealthiest individuals in history. Adjusted for inflation, his fortune is estimated to have reached the equivalent of $400 billion.
• Mansa Musa, the 14th-century emperor of the Mali Empire, is often described as the richest man who ever lived. His empire controlled vast gold reserves, making him extraordinarily powerful. However, historians caution that his true wealth cannot be quantified in today’s monetary terms.
• Andrew Carnegie and other industrial titans of the Gilded Age also amassed fortunes that represented massive shares of the global economy at the time, though none cross into Musk’s territory when converted to present-day values.
A Question of Value
Economists note that Musk’s half-trillion fortune is largely “on paper,” dependent on stock valuations and private company estimates. In contrast, historical figures like Mansa Musa measured wealth in tangible assets such as gold, land, and resources.
Yet the milestone highlights how concentrated wealth has become in the age of technology and global capital markets. As Musk himself continues to expand his ventures into space, AI, and energy, his financial dominance represents both a symbol of modern capitalism and a question mark about wealth inequality.
Bottom Line: In modern financial history, Elon Musk is the first and only person to reach $500 billion in net worth, though history remembers others—like Rockefeller and Mansa Musa—whose fortunes in relative terms may have rivaled or even surpassed his.
