Ten years ago, being worth $50 billion was enough to put someone among the richest people on the planet. Today, that figure doesn’t even guarantee a place in the top 10.
A look at the global rich list over the past decade shows just how dramatically wealth has expanded at the very top, largely fueled by the rise of technology companies and booming stock markets. According to the Bloomberg Billionaires Index, the world’s 10 richest people together were worth about $559 billion at the end of 2015. In 2026, that combined wealth has jumped to nearly $2.6 trillion.
The world’s 10 richest people in 2016 and 2026
| Rank | 2016 Richest Person | Net Worth (2016) | 2026 Richest Person | Net Worth (2026) |
|---|---|---|---|---|
| 1 | Bill Gates | $84 billion | Elon Musk | $682 billion |
| 2 | Amancio Ortega | $73 billion | Larry Page | $285 billion |
| 3 | Warren Buffett | $63 billion | Sergey Brin | $264 billion |
| 4 | Jeff Bezos | $59 billion | Jeff Bezos | $260 billion |
| 5 | Carlos Slim | $53 billion | Larry Ellison | $242 billion |
| 6 | Charles Koch | $50 billion | Mark Zuckerberg | $220 billion |
| 7 | David Koch | $50 billion | Bernard Arnault | $200 billion |
| 8 | Mark Zuckerberg | $46 billion | Steve Ballmer | $160 billion |
| 9 | Larry Page | $40 billion | Jensen Huang | $155 billion |
| 10 | Larry Ellison | $40 billion | Warren Buffett | $148 billion |
The biggest change is at the very top. Elon Musk, the CEO of Tesla and SpaceX, is now the world’s richest person, with an estimated net worth of $682 billion — a figure that dwarfs anything seen a decade ago.
Familiar names, very different numbers
Many of the names leading the wealth rankings in 2016 are still familiar today. Back then, the top 10 included Bill Gates, Amancio Ortega, Warren Buffett, Jeff Bezos, Carlos Slim, Charles Koch, David Koch, Mark Zuckerberg, Larry Page and Larry Ellison.
While most of them remain among the world’s wealthiest, their positions — and fortunes — have shifted. Alphabet cofounders Larry Page and Sergey Brin now rank second and third globally, each worth more than $250 billion. Bezos, who founded Amazon, sits in fourth place with a fortune of about $260 billion.
Oracle cofounder Larry Ellison and Meta CEO Mark Zuckerberg follow, with net worths of roughly $242 billion and $220 billion. They are joined in today’s top 10 by LVMH chief Bernard Arnault, former Microsoft CEO Steve Ballmer, Nvidia CEO Jensen Huang and veteran investor Warren Buffett.
All of the billionaires who were in the top 10 in 2016 remain in the top 25 today, with one exception. David Koch, who died in 2019, has been replaced by his widow, Julia Flesher Koch, and her family, who now rank 22nd globally.
Giving away wealth — and falling down the list
Not everyone who slipped down the rankings did so because their businesses struggled. In many cases, the fall reflects slower growth compared with tech fortunes, or a decision to give money away.
Bill Gates, once the richest person in the world, has dropped to 17th place. Much of that is due to his philanthropy. He and his former wife, Melinda French Gates, have donated more than $60 billion to the Gates Foundation. Gates has also pledged to give away nearly all of his remaining wealth over time.
Warren Buffett’s decline follows a similar path. Once ranked third globally, he now sits at 10th after giving away more than half of his Berkshire Hathaway shares.
The investor said last November that “he’d like his three children, now in their 60s and 70s, to disburse virtually all of his wealth in their lifetimes.”
Others have simply been overtaken by faster-growing tech fortunes. Inditex founder Amancio Ortega has slipped from second place to 15th, even though his net worth has nearly doubled. Telecom billionaire Carlos Slim has dropped from fifth to 16th, while industrialist Charles Koch has fallen from sixth to 24th.
A different scale of wealth
What stands out most is not who is rich, but how rich they are. In 2016, the top 10 fortunes ranged from about $40 billion to $84 billion. Today, the smallest fortune in the top 10 is around $148 billion.
Put another way, the world’s richest person today is roughly eight times wealthier on paper than the richest individual was a decade ago.
Musk’s rise explains much of that gap. Tesla’s stock has surged roughly 27-fold over the past decade, even after accounting for stock splits, pushing the company’s valuation to about $1.5 trillion. SpaceX is now valued at around $800 billion, while Musk’s AI venture, xAI, was valued at roughly $230 billion this month.
Together, the numbers show how quickly wealth can grow in the modern tech-driven economy — and how far today’s billionaires are operating on a completely different scale than those who topped the list just 10 years ago.
