No, there are no trillionaires currently, but experts predict the world's first individual trillionaire could emerge within the next decade, with figures like Elon Musk often cited as potential candidates due to rapid wealth growth, though no one has reached that unprecedented level of net worth yet. While companies have hit the $1 trillion mark, no single person has achieved $1 trillion in personal wealth.
Musk and other extremely wealthy individuals—including Meta CEO Mark Zuckerberg and Oracle co-founder Larry Ellison, whose net worth briefly overtook Musk's earlier this year—have already frequently ranked among TIME's most influential people for their roles in shaping our world.
Elon Musk has become the first person in history with a net worth of 500 billion US dollars. The Tesla and SpaceX CEO's fortune has crossed the half-trillion mark. At his current pace, Musk could become the world's first trillionaire by 2033, when Tesla's proposed 1 trillion dollar compensation package begins vesting.
No single group holds exactly 90% of the world's wealth, but extreme concentration exists, with the top 10% of the world's population owning the vast majority, around 75-85% of global wealth, leaving the bottom 90% with a small fraction, while the richest 1% owns a huge chunk of that, sometimes as much as the bottom 90% or more combined, according to reports from the World Inequality Database and Oxfam.
As of late 2024 and into 2025, Elon Musk was the first person to reach a net worth exceeding $400 billion, primarily from his stakes in Tesla, SpaceX, and xAI, with Larry Ellison briefly surpassing him in September 2025 due to Oracle's stock surge, though Musk generally remains the wealthiest individual.
Youngest is 19-year-old Johannes von Baumbach, an heir to the Boehringer Ingelheim fortune, a company best known as the largest private pharmaceutical company. The oldest, at 103, is George Joseph, the founder of in 1962 of Mercury General, an insurance provider with $5.5 billion in annual revenues.
The title of the world's youngest billionaire (age 19) has recently been held by Livia Voigt, a Brazilian student and heiress to the WEG electrical equipment company, and in other reports, Johannes von Baumbach, heir to the German pharmaceutical giant Boehringer Ingelheim, though sources vary slightly on who holds the top spot at any given time, both are heirs inheriting fortunes from family businesses. While Livia Voigt's wealth comes from a minority stake in WEG, and von Baumbach's from his family's stake in Boehringer Ingelheim, both inherited their billions rather than earning them self-made.
Kylie Jenner has publicly shared diagnoses and struggles including Postpartum Depression (PPD), chronic back pain after her second pregnancy treated with stem cell therapy, and a past diagnosis of Recurrent Corneal Erosion Syndrome, a painful eye condition, as noted in various news reports from 2020 to 2025.
At the pinnacle of our saga stands the House of Saud, rulers of the Kingdom of Saudi Arabia since 1744. King Salman, presiding since 2015, oversees a dynasty that boasts a staggering net worth of $1.4 trillion (£1.1tn). Their opulence eclipses entire economies, and their influence reverberates across nations.
There's no official, verified IQ score for Mark Zuckerberg, but estimates widely place it around 152, suggesting genius-level intellect, though some sources give a broader range like 135-160, inferred from his immense success and problem-solving, not a documented test.
Add in the cash Jenner has already pulled from the profitable business, and the 21-year-old is now a billionaire, with an estimated fortune of $1 billion. She's the youngest-ever self-made billionaire, reaching a ten-figure fortune at a younger age than even Mark Zuckerberg (who was 23 when he hit that mark).
