The Youngest Billionaires in the World (2025): Who They Are and How They Got Rich

When it comes to the Youngest Billionaires in the World in 2025, you might initially envision teen prodigies in Silicon Valley or high-flying startup founders making headlines at tech conferences. Yet recent data reveals a more traditional reality: a majority of these ultra-young billionaires actually come from families with well-established businesses. That often means inheriting shares of industrial powerhouses, global retail networks, or even gaming conglomerates. This steady flow of intergenerational wealth showcases how dynasties continue to wield significant influence, even in a tech-driven era where we typically celebrate self-made digital entrepreneurs.

In this list, we’ll highlight those under 35 who’ve landed among the Youngest Billionaires in the World, focusing on their ages, countries of origin, and how they ascended to the billionaires’ club. You’ll find a diverse cast of characters—Brazilian heiresses, Italian brothers, Korean gaming inheritors, and Indian-origin siblings with ties to Ireland. Though each story is unique, they share a unifying theme: an inheritance that thrust them into extraordinary financial power well before turning 30. It’s a fascinating look at how wealth, legacy, and sometimes geography can intersect to shape the next generation of global power players.

1. Livia Voigt (Age 20, Brazil)

Often topping discussions about the Youngest Billionaires in the World, Livia Voigt stands as the youngest of them all at age 20. She inherited about 3.1% of WEG, a massive Brazilian electrical motor manufacturer co-founded by her grandfather, placing her net worth in the ballpark of $1.1 to $1.3 billion. At present, she remains a university student focused on coursework rather than executive obligations, which reflects a broader trend among heirs who acquire sizable wealth at a tender age.

Her situation nicely captures a dynamic among the Youngest Billionaires in the World: She wields considerable financial clout by virtue of family shares but hasn’t taken on a leadership role. Many watchers wonder if she’ll one day step into corporate stewardship or if she’ll pursue a different path entirely. Given WEG’s prominence in Latin America, any move she makes—whether joining the board or staying behind the scenes—could shape the company’s evolving trajectory. Until then, she remains an intriguing figure whose path underscores the complexities of inheriting great wealth early in life.

2. Clemente Del Vecchio (Age 20, Italy)

Clemente Del Vecchio is another standout in discussions about the Youngest Billionaires in the World. He inherited a 12.5% stake in Delfin, the holding company behind EssilorLuxottica and other diverse investments, resulting in a net worth of around $5.2 billion. For a 20-year-old, that magnitude of wealth dwarfs many entrepreneurs who’ve spent decades building businesses, underscoring how robustly dynastic influence still permeates global markets.

In the bigger conversation about the Youngest Billionaires in the World, Clemente is notable for expressing interests that lie beyond the family’s eyewear empire—possibly in technology and science. Such aspirations open intriguing possibilities: Will he reimagine Delfin’s investment strategy to incorporate emerging sectors, or adopt a more hands-off approach? Either way, his story speaks to how established family wealth continues to shape modern finance, even as headlines often focus on self-made tech unicorns.

3. Kim Jung-youn (Age 21, South Korea)

Kim Jung-youn joins the Youngest Billionaires in the World club at age 21, courtesy of a major stake in NXC, parent to the globally recognized gaming giant Nexon. Her share, along with her sister’s, amounts to roughly 18% of the holding company, translating to a net worth of $1.3 to $1.4 billion. Despite this monumental valuation, Kim is known for her reserved lifestyle and absence from Nexon’s corporate activities.

Her journey epitomizes a hallmark of the Youngest Billionaires in the World: an up-and-coming tech domain—online gaming—combined with a timely inheritance catapulting her to billionaire status. Observers note that Nexon’s expansion, especially in regions like North America and Europe, plays a direct role in Kim’s sustained wealth. Whether she’ll eventually become more hands-on remains unknown, but her presence at the intersection of gaming and generational wealth adds depth to ongoing conversations about Asia’s shifting power structures.

4. Kevin David Lehmann (Age 22, Germany)

Frequently cited in any discussion of the Youngest Billionaires in the World, Kevin David Lehmann inherited a 50% stake in dm-drogerie markt—Germany’s largest drugstore chain—when he was just 14 years old. That staggering event set him on a path to a $3.3 billion net worth by age 22, a scenario nearly unimaginable for most teens. While his peers worried about school exams or weekend plans, Kevin’s share in dm quietly ballooned alongside the company’s robust performance.

Interestingly, Kevin does not participate in the chain’s operational management, adhering to a pattern seen among several heirs within the Youngest Billionaires in the World circle. Whether he chooses to become actively involved in retail strategy down the line or continues to take a passive seat remains to be seen. For now, his story underscores how family wealth, cemented through decades of business growth, can be passed along, granting extraordinary financial advantages well before adulthood is fully underway.

5. Luca Del Vecchio (Age 23, Italy)

Another prominent name in the Del Vecchio family, Luca strengthens his position among the Youngest Billionaires in the World by inheriting 12.5% of Delfin, mirroring his brother Clemente’s shares. This inheritance, worth around $4.7 billion, ties him closely to the successes (and potential pitfalls) of EssilorLuxottica, along with other significant investments. However, unlike some who opt to stay in the background, Luca plays an active part in shaping the family business.

Serving as chief strategy officer at Delfin, Luca demonstrates a willingness to get hands-on—a rarity among certain heirs who are content merely collecting dividends. This engagement might grant him a powerful role in steering EssilorLuxottica’s next moves, particularly as eyewear markets evolve and new technologies emerge. For those tracking the Youngest Billionaires in the World, he offers an example of how an heir can merge traditional legacy with modern strategic thinking.

6. Kim Jung-min (Age 23, South Korea)

Kim Jung-min, older sister to Kim Jung-youn, adds further intrigue to the Youngest Billionaires in the World roster. She maintains approximately a 9% slice of NXC, anchoring her net worth at around $1.4 billion. Sharing much with her sister, she, too, opts for a private lifestyle and refrains from direct engagement in Nexon’s everyday operations.

Their sibling dynamic highlights a fascinating aspect of the Youngest Billionaires in the World narrative: families can jointly hold significant stakes in thriving tech entities, effectively splitting the immense fortune. While both sisters remain on the periphery for now, any future decisions—like expansions or acquisitions—could see them stepping into more proactive roles. This scenario underscores how generational wealth distribution can profoundly influence major companies without the heirs necessarily being in the limelight.

7. Remi Dassault (Age 23, France)

Among the Youngest Billionaires in the World, Remi Dassault’s fortune originates from the Dassault family empire, which encompasses everything from aerospace to software and even wine production. After his father’s passing, Remi inherited significant stakes in Dassault Aviation and Dassault Systèmes, valued at around $2.5 billion. This substantial wealth keeps him firmly in the public eye, especially given the Dassault name’s long-standing influence in French industry and political circles.

While some scions rush to take on formal leadership, Remi takes a more measured approach, preferring to let established managers handle day-to-day affairs. This approach is echoed by many in the Youngest Billionaires in the World, indicating that owning large shares doesn’t always equate to hands-on corporate involvement. Nonetheless, the Dassault family’s storied history suggests ample opportunities should Remi decide to align himself more closely with the enterprise, be it in aviation, high-tech software solutions, or even ventures like media.

8. Zahan Mistry (Age 26, Ireland/Indian Citizenship)

Zahan Mistry’s story adds a layer of uniqueness to the Youngest Billionaires in the World mix. Inheriting parts of the Tata Sons stake and the Shapoorji Pallonji Group shares after his father Cyrus Mistry’s passing, Zahan’s net worth is around $4.9 billion. This dual connection links him to two of India’s most powerful business spheres: Tata’s broad conglomerate and the Shapoorji Pallonji empire famed for its construction and engineering achievements.

Unlike some heirs who prefer minimal involvement, Zahan is said to be actively engaged in the family’s infrastructural endeavors. That level of participation could shape how his inherited capital is deployed—potentially toward new IPOs, expansions, or modernizing certain aspects of the conglomerates. For those observing the Youngest Billionaires in the World, Zahan stands out as someone bridging Ireland and India’s business worlds, illuminating how global corporate legacies can be both inherited and actively steered into the future.

9. Dora Voigt de Assis (Age 27, Brazil)

Dora Voigt de Assis, older sister of Livia Voigt, also claims a spot among the Youngest Billionaires in the World thanks to inheriting a similar 3.1% stake in WEG. Her net worth parallels her sister’s at roughly $1.1–1.3 billion. Possessing an architecture degree, Dora spends her time focusing on personal pursuits rather than immersing herself in the family’s industrial operation.

Her presence underscores how multiple siblings can each secure a place in the Youngest Billionaires in the World listings when large company shares get split within a family. While some might question whether either sister will eventually take on more active roles, for now they appear content to maintain a lower public profile. It’s an intriguing example of how vast fortunes can remain quietly on the periphery, all while influencing a major Latin American manufacturer that provides essential industrial components worldwide.

10. Firoz Mistry (Age 28, Ireland/Indian Origin)

Rounding out the Youngest Billionaires in the World is Firoz Mistry, Zahan’s brother and another recipient of the Tata Sons and Shapoorji Pallonji Group inheritance. At 28, he sits on an estimated $4.9 billion net worth, aligning him closely with his sibling’s financial standing. While details about his day-to-day involvement remain somewhat sparse, he’s thought to be weighing how best to engage with the sprawling array of companies under the family umbrella.

His inclusion confirms the deep-reaching power the Mistry clan wields in India’s industrial and financial sectors, reinforcing their role in shaping everything from steel production to software solutions. Observers wonder if Firoz might push new innovations or expansions, or if he’ll simply uphold existing frameworks crafted by prior generations. Whatever his path, he and his brother typify the complexities of inheriting a multinational conglomerate, showcasing how the Youngest Billionaires in the World often stand at crossroads between tradition and modernization.

Riches at So Young

All ten of these under-35 heirs exemplify how the Youngest Billionaires in the World in 2025 tend to be beneficiaries of significant family holdings. Whether we’re talking about Brazilian sisters tied to WEG, the Del Vecchio brothers and their eyewear empire, or the Mistry siblings navigating Tata Sons, the pattern is clear: inheritance remains a potent force in global wealth distribution. While the media often glorifies self-made founders, these examples remind us that dynastic fortunes continue to shape industries and create new billionaire headlines year after year.

For anyone curious about how next-generation leaders might transform their inherited empires, these stories offer a revealing lens. Some heirs—like Luca Del Vecchio and Zahan Mistry—show a willingness to roll up their sleeves and drive strategic decisions, indicating possible shifts or expansions that could redefine major companies. Others maintain a more passive stance, satisfied with sizeable ownership stakes and the freedom to explore personal endeavors. Regardless, the Youngest Billionaires in the World have a unique vantage point: they hold immense wealth at a life stage when most are just starting to carve out their professional identities. With that comes both daunting responsibility and unparalleled opportunity, ensuring these names will remain intriguing figures to watch for years—and possibly decades—to come.
