Amelie Voigt Trejes Net Worth 2026: The World’s Youngest Billionaire Explained
Amelie Voigt Trejes is a 20-year-old Brazilian university student and the granddaughter of WEG co-founder Werner Ricardo Voigt, named by Forbes as the world’s youngest billionaire in 2026.
Amelie Voigt Trejes net worth estimated is approximately $1.1 billion, built on a roughly 2 percent inherited stake in WEG, Latin America’s largest electric motor manufacturer, passed down through her mother, Cladis Voigt. She is reported to be about seven weeks younger than the previous titleholder, German pharma heir Johannes von Baumbach. This is inherited, estimated equity, not confirmed cash.
Key Takeaways
- Amelie Voigt Trejes’s 2026 net worth is estimated at approximately $1.1 billion, according to Forbes’ official billionaire tracker, based on a roughly 2 percent stake in WEG.
- Her wealth is inherited through her mother, Cladis Voigt, one of WEG co-founder Werner Ricardo Voigt’s three children, not through her own business activity.
- Forbes’ March 2026 rankings name her the world’s youngest billionaire at 20, narrowly younger than Johannes von Baumbach by about seven weeks.
- She has twin brothers, Pedro and Felipe Voigt Trejes, each also worth an estimated $1.1 billion through the same inheritance.
- She holds no board seat or executive role at WEG, is reportedly a university student, and keeps an unusually low public profile with no confirmed interviews on record.
Who Is Amelie Voigt Trejes
Amelie Voigt Trejes is a 20-year-old Brazilian woman who became, according to Forbes’ 2026 World’s Billionaires list, the youngest billionaire currently alive. She is a granddaughter of Werner Ricardo Voigt, one of the three founders of WEG, the industrial electric motor manufacturer headquartered in Jaraguá do Sul, Santa Catarina.
Her Basic Profile
Before going further into the financial detail, a few core facts about who she is and where her wealth comes from are worth stating plainly, since much of the coverage of her assumes readers already know this background.
- She is a Brazilian national, associated with Santa Catarina, the same state where WEG was founded and remains headquartered.
- She is reported to be a university student who does not run any part of WEG’s daily operations, according to Vanguard News’ profile of the world’s youngest billionaires.
- Her fortune is inherited, not self-made, tracing back to her grandfather’s founding role at WEG in 1961.
- She has two twin brothers, Pedro and Felipe Voigt Trejes, who inherited comparable stakes and are each also billionaires.
Where Amelie Voigt Trejes’s Fortune Actually Comes From
Amelie Voigt Trejes has never run a company, launched a product, or negotiated a business deal. Her fortune exists because of decisions made by her grandfather more than sixty years before she was born, filtered down through two generations of inheritance rather than one.
The WEG Connection
WEG was founded in 1961 in Jaraguá do Sul by three partners, Werner Ricardo Voigt, Eggon João da Silva and Geraldo Werninghaus, whose first names form the company’s acronym, according to Rio Times’ reporting on the wider Voigt family. The company started by making electric motors for Brazil’s industrializing economy and went public on Brazil’s stock exchange under the ticker WEGE3 in 1971, according to BrandClickX’s detailed account of the company’s history.
More than six decades later, WEG has grown into Latin America’s largest manufacturer of electrical motors, generators, transformers and industrial automation systems, generating roughly $7 billion in annual revenue and carrying a market capitalization reported at approximately R$195 billion, or about $34 billion, according to Rio Times’ coverage of the family.
Amelie’s path to that fortune runs through her mother rather than directly from her grandfather. When Werner Ricardo Voigt died in 2016, his WEG stake was divided among his three children through the family’s WPA Participações holding structure. Cladis Voigt, Amelie’s mother, received her share, and later passed portions of that inheritance down to her own three children, according to BrandClickX’s profile of Amelie.
That two-step inheritance is why Amelie is described as a granddaughter of WEG’s founder rather than a direct heir to his original stake, and it is also the mechanism behind why so many Voigt cousins have become billionaires at roughly the same time: every time a stake passes down a generation inside the family structure, it splits into smaller pieces distributed among more people.
Forbes and several outlets covering the 2026 rankings put Amelie’s individual ownership at approximately 2 percent of WEG, a figure repeated across multiple reports citing Forbes’ own data. That specific percentage is smaller than some of her cousins’ stakes, which is part of why her estimated net worth sits at the lower end of the seven-cousin group despite all of them descending from the same original founder.
How Inheritance Created Her Wealth
Amelie’s situation illustrates something particular about how family industrial fortunes multiply across generations. A single founder’s stake does not simply pass to one successor; it can fragment repeatedly as it moves from grandparent to parent to grandchild, producing several billionaires from what was originally one large ownership position.
That is precisely what happened inside the Voigt family: Werner Ricardo Voigt’s original stake, split three ways among his children, has now produced seven billionaire grandchildren across three separate family branches.
She does not hold a board seat or any executive position at WEG, according to multiple profiles including Forbes’ official page on her, and her wealth is best understood as an estimated market value tied to a public company’s share price rather than money she can freely access. Because WEG trades publicly, her stake’s value moves with the stock daily, the same way any large shareholder’s paper wealth would.
WEG’s History From a Small Workshop to a Global Manufacturer
Understanding Amelie’s fortune requires understanding just how far WEG has come from its original three-person workshop, since the company’s growth is the entire reason a 2 percent stake is worth anything close to a billion dollars today.
From Jaraguá do Sul to Forty Countries
WEG’s founders had no way of knowing what they were building when they started making electric motors in 1961, but Brazil’s rapid industrialization gave the young company a steady stream of demand from factories, farms and power plants that needed motors to run, according to BrandClickX’s account of the company’s early years. Its 1971 listing on Brazil’s stock exchange gave it access to capital for expansion, and the decades that followed saw the company grow first across Brazil, then across Latin America, then into a genuinely global manufacturer.
A few figures capture the scale WEG has reached since then.
- The company now operates in more than ten countries with manufacturing facilities and a presence in more than 40 countries overall, according to Rio Times’ reporting.
- Annual revenue is reported at approximately $7 billion.
- WEG’s market capitalization has been reported at roughly R$195 billion, or about $34 billion, making it one of Brazil’s largest listed industrial companies.
- The company today makes far more than its original electric motors, including generators, transformers and industrial automation systems.
That growth trajectory, sustained over more than sixty years, is the entire reason a minority stake inherited two generations removed from the founder can still be worth close to a billion dollars.
How Amelie Became the World’s Youngest Billionaire
The title of world’s youngest billionaire has changed hands repeatedly in recent years, and Amelie’s own claim to it came down to a genuinely narrow margin.
A Seven Week Age Gap
In early 2026, as Forbes finalized its annual World’s Billionaires list, two candidates were tied for the youngest spot: both 20 years old, both having just crossed the billion-dollar threshold. One was Amelie Voigt Trejes; the other was Johannes von Baumbach, a German heir to the Boehringer Ingelheim pharmaceutical fortune worth an estimated $6.6 billion, according to BrandClickX’s account of the ranking.
Amelie won the title by age alone, having been born roughly seven weeks after Johannes, despite his fortune being worth several times more than hers. Forbes’ own profile of Johannes confirms that Amelie Voigt Trejes deposed him for the youngest-billionaire title in 2026, a detail also covered in StarWealthInsider’s own profile of Johannes von Baumbach’s net worth.
This is at least the fourth time the title has changed hands since 2022, moving from Italian heir Clemente Del Vecchio’s net worth to Livia Voigt in 2024, then to Johannes von Baumbach in 2025, and finally to Amelie in 2026, a pattern that underscores how fragile and age-dependent this specific record really is. It is also worth noting that Amelie shares this record narrowly with her twin brothers Pedro and Felipe Voigt Trejes, who are the same age and worth the same estimated amount, though Forbes’ methodology apparently credits Amelie individually as the named record holder.
Her Age and Background
Amelie is reported to be 20 years old as of the 2026 Forbes rankings, with limited additional biographical detail available in the sources reviewed for this article. She has never given a public interview about her wealth, according to BrandClickX’s profile, which is consistent with the broader Voigt family’s low public profile; her cousin, Livia Voigt’s net worth, has been covered more extensively in press largely because Livia held the same youngest-billionaire title two years earlier, in 2024.
Amelie Voigt Trejes’s Net Worth in 2026
Because WEG is publicly traded, Amelie’s net worth is grounded in a real, checkable share price, which sets her apart from heirs to fully private companies like Johannes von Baumbach.
The 2026 Estimates
The table below lays out what different outlets have reported, rather than treating one figure as automatically correct.
| Source | Estimated Figure | Date | What It Measures | Reliability |
|---|---|---|---|---|
| Forbes official profile | Approximately $1.1 billion, ranked #3185 on Forbes’ 2026 list | March 2026 | Estimated personal wealth from her roughly 2% WEG stake | High, official Forbes tracker |
| Iconic Billionaires | Approximately $1.1 billion, global rank #3288 | Mid-2026 | Estimated inheritance-linked fortune | Secondary, lower confidence than Forbes |
| VnExpress, citing Forbes | Approximately $1.1 billion | March 2026 | Reported alongside the world’s five youngest billionaires | Secondary, citing Forbes directly |
| forbesrichest tracker | Approximately $1.0 billion | Checked mid-2026 | Real-time wealth tracker | Secondary, unofficial name similar to Forbes but not affiliated |
Unlike some of the wider Voigt family’s other net worth estimates, which range more broadly, most trackers covering Amelie specifically cluster tightly around $1.1 billion, which suggests unusually strong agreement for a young heir’s estimated fortune.
Amelie Voigt Trejes Net Worth in 2025 Compared With 2026
Unlike her cousin Livia, who first appeared on Forbes’ billionaire rankings back in 2024, Amelie, Pedro and Felipe Voigt Trejes joined the list as newcomers only in 2026, according to Rio Times’ reporting on the family. That means there is no earlier Forbes-sourced net worth figure to compare against; she was not tracked as a billionaire prior to this year.
| Period | Status | Source | Notes |
|---|---|---|---|
| 2025 | Not yet listed as a billionaire by Forbes | Rio Times | She, Pedro and Felipe are described as “newcomers” to the 2026 list, implying no prior listed figure |
| March 2026 | Approximately $1.1 billion | Forbes | Debut appearance on Forbes’ World’s Billionaires and World’s Youngest Billionaires lists |
| Mid-2026 | Approximately $1.0 billion to $1.1 billion | Iconic Billionaires, forbesrichest | Secondary trackers, broadly consistent with the Forbes figure |
No reputable source reviewed for this article provides a 2025 dollar figure for Amelie specifically, so this article does not invent one to fill the gap.
Why the Figures Barely Differ
The consistency in the 2026 estimates comes down to two things working in her favor compared with other young billionaires. First, WEG is publicly traded, so there is a real daily share price to work from rather than a private-company valuation guess. Second, her stake size appears to be consistently reported across sources at approximately 2 percent, unlike cases where different trackers assume different ownership percentages.
That said, even a publicly traded stake is not the same as spendable cash. Her shares are still subject to the stock’s daily price movements, and any figure quoted here reflects a snapshot rather than a fixed number. None of the estimates account for Brazilian taxes, potential family agreements restricting when shares can be sold, or the practical difficulty of converting a large shareholding into cash without affecting the stock price.
Amelie Voigt Trejes’s Family and the Wider Voigt Fortune
Amelie’s fortune is one piece of a much larger family wealth story, and it is easy to conflate her individual net worth with the family’s combined total.
Her Immediate Family
Amelie’s mother, Cladis Voigt, is one of Werner Ricardo Voigt’s three children and the source of Amelie’s inherited stake. No source reviewed for this article documents her father’s identity, so this article does not name one.
Amelie has twin brothers, Pedro and Felipe Voigt Trejes, who inherited comparable stakes from the same source and are each independently worth an estimated $1.1 billion, according to Rio Times’ coverage of the family. All three siblings joined Forbes’ billionaire rankings as newcomers in the same 2026 list.
The Seven Voigt Cousins
Amelie is one of seven grandchildren of Werner Ricardo Voigt who now appear on Forbes’ billionaire rankings, a group whose combined fortune has been reported at roughly $9.5 billion.
That group includes her cousins Eduardo and Mariana Voigt Schwartz, each worth an estimated $1.7 billion, and cousins Livia and Dora Voigt de Assis, each worth an estimated $1.3 billion to $1.4 billion depending on the date, whose own fortune is covered in more detail in StarWealthInsider’s profile of Livia Voigt’s net worth.
None of these individual figures should be merged with Amelie’s own $1.1 billion estimate, since each cousin holds a separately valued stake inherited through a different branch of the family.
The Wider Founding Family
Beyond Werner Ricardo Voigt’s own descendants, WEG’s other two founding families have also produced billionaire heirs. Forbes identifies Anne Marie Werninghaus, a descendant of co-founder Geraldo Werninghaus, as the largest individual shareholder among the company’s founding families, with an estimated fortune of R$9.1 billion, or roughly $1.7 billion, according to CPG Click Oil and Gas’ coverage of her business ventures.
That detail is a useful reminder that Amelie’s branch of the family is only one of three founding lineages whose descendants now hold significant WEG wealth, and that the company’s total founder-linked fortune extends well beyond the Voigt name alone.
Is Amelie Voigt Trejes Married?
Public curiosity about young billionaires often extends into their personal lives, and Amelie’s is essentially undocumented in reliable reporting.
Her Personal Life
No reliable public source reviewed for this article confirms Amelie Voigt Trejes’s marital status, romantic relationships, or place of residence beyond her general association with Brazil. She has given no public interviews about her wealth, according to BrandClickX’s profile, and this article does not speculate about her personal life beyond what has been directly and reliably reported.
Why Amelie Voigt Trejes’s Story Matters
Amelie’s story is a clear illustration of how a single industrial fortune can multiply across a family over time, producing several billionaires from what began as one founder’s ownership stake.
One Fortune, Seven Billionaires
Every time Werner Ricardo Voigt’s original WEG stake passed down a generation, it split into smaller, independently owned pieces, and each of those pieces has since grown large enough on its own to clear the billion-dollar threshold.
That pattern is unusual even among family-controlled fortunes, and it explains why headlines about “the world’s youngest billionaire” have cycled so quickly through related heirs in recent years rather than settling on one name for long.
It is also worth noting how differently this kind of wealth compares with fortunes built through direct entrepreneurship. Where Amelie’s fortune traces back entirely to a stake her grandfather built more than sixty years ago, StarWealthInsider’s profile of Elon Musk’s net worth reflects wealth built through operating roles at multiple companies the person founded or led directly, a fundamentally different and far less common path to extreme wealth than the inheritance route that produced Amelie’s fortune.
