Amelie Voigt Trejes is worth an estimated $1.1 billion, according to Forbes’ 2026 World’s Billionaires list, published March 10, 2026. A separate Forbes real-time tracker placed her fortune closer to $1 billion as of July 7, 2026, reflecting daily swings in the value of her WEG shares. At just 20 years old when the annual list came out, Amelie Voigt Trejes became the world’s youngest billionaire, a title tied entirely to inherited stock in one of Brazil’s largest industrial companies.
Her story is less about building a business and more about what happens when a family fortune passes down through three generations of a publicly traded company. Here is what is actually confirmed about her wealth, her family, and the company behind it all.

Who Is Amelie Voigt Trejes?
Amelie Voigt Trejes is a young Brazilian heiress whose fortune comes from her family’s stake in WEG, a Jaraguá do Sul-based manufacturer of electric motors, generators, transformers, and industrial automation equipment. She is the granddaughter of Werner Ricardo Voigt, one of WEG’s three founders, and the daughter of Cladis Voigt, one of his three children.
Forbes lists her residence as Florianópolis, Brazil, and describes her as single with no children. No reliable, independently verifiable reporting on her education has surfaced, so any specific claims about where she studied should be treated as unconfirmed until a credible source publishes them.
What makes her case notable isn’t a business she built or a company she runs. It’s the math of generational wealth: a single ownership stake, split repeatedly across children and grandchildren in a company whose share price keeps climbing, can turn quietly into several individual billion-dollar fortunes within one extended family.
Amelie Voigt Trejes Net Worth: How Much Is She Worth?
The confirmed figure is $1.1 billion, as published in Forbes’ 2026 World’s Billionaires list on March 10, 2026, where she ranked #3185 globally. Forbes also maintains a real-time valuation that moves with WEG’s stock price on Brazil’s B3 exchange; that tracker showed her net worth at roughly $1 billion as of July 7, 2026.
Brazilian financial outlets, citing a Forbes update from late August 2026, reported her fortune at approximately R$5.67 billion to R$6.7 billion (also converting to around $1.1 billion), by which point her age was listed as 21. The gap between these figures isn’t a case of conflicting sources getting it wrong. It reflects how Forbes calculates billionaire wealth for people whose fortune sits in publicly traded stock: the number is reassessed on a rolling basis as the underlying share price moves, so the “net worth” reported in March, July, and August of the same year can legitimately differ.
A handful of third-party wealth-tracking sites also list figures in the same $1.0 billion to $1.1 billion range. These sites generally repackage Forbes’ own estimates rather than independently verifying them, so Forbes remains the primary and most reliable source for her net worth.
It’s worth being precise about terminology here, since the numbers attached to Amelie Voigt Trejes get mixed up easily:
- Net worth ($1.1 billion, Forbes) is the estimated value of her personal ownership stake.
- WEG’s revenue (approximately $7 billion annually, as reported by Forbes) is the company’s total sales, not her personal income.
- WEG’s market capitalization (approximately R$210.8 billion as of the B3 close on August 28, 2026, as reported by Brazilian financial media) is the value of the entire company on the stock market, not any single shareholder’s stake.
She has no reported salary, since she holds no executive position, and no disclosed liabilities.
How Amelie Voigt Trejes Makes Her Money: WEG Ownership Explained
Amelie Voigt Trejes’s fortune comes entirely from equity, not earned income. According to Brazilian financial press reporting from August 2026, her ownership breaks down into two layers:
Direct ownership: She holds 5,282,602 common shares of WEG directly, equal to about 0.126% of the company’s total share capital.
Indirect ownership: She holds a 33.33% stake in each of two family holding companies, Cladis Voigt Trejes Administradora Ltda. (split evenly with her twin brothers) and Clica Voigt Administradora Ltda., a separate family patrimonial entity.
Combined, her direct and indirect holdings are reported at roughly 2.54% of WEG, equivalent to about 106.7 million shares in total. That combined stake, not the 0.126% figure alone, is what underlies her billion-dollar valuation.
This structure is fairly typical for family-controlled Brazilian conglomerates: rather than each heir holding a simple personal brokerage account full of stock, ownership flows through layered holding companies that keep the family’s collective control over WEG intact while still allowing each member’s individual share to be tracked and valued separately.
Family: Parents, Siblings and the Voigt Family Tree
The wealth traces back to one person: Werner Ricardo Voigt, born September 8, 1930, who cofounded WEG in 1961 alongside Eggon João da Silva and Geraldo Werninghaus. He died on June 1, 2016, at age 85, of natural causes, in Jaraguá do Sul, according to WEG’s official statement at the time.
Werner Ricardo Voigt had three children, and his stake in the company was divided among them. Amelie’s mother, Cladis Voigt, was one of those three. As reported by Brazilian outlets, each of Werner’s children later passed portions of their inheritance down to their own children, which is how a single founder’s stake fragmented into multiple separate billion-dollar fortunes within one generation of cousins.
Amelie has two brothers, twins Pedro and Felipe Voigt Trejes, who are also WEG shareholders and billionaires in their own right, each reportedly worth about $1.1 billion. Sources differ slightly on the twins’ exact age relative to Amelie’s, so that detail should be treated as unconfirmed pending clearer reporting.
She also has several cousins on the 2026 Forbes list, all grandchildren of Werner Ricardo Voigt through his other two children:
| Family member | Relationship | Reported net worth (2026) |
| Amelie Voigt Trejes | Granddaughter | $1.1 billion |
| Pedro Voigt Trejes | Grandson (Amelie’s twin brother) | $1.1 billion |
| Felipe Voigt Trejes | Grandson (Amelie’s twin brother) | $1.1 billion |
| Lívia Voigt de Assis | Granddaughter | $1.4 billion |
| Dora Voigt de Assis | Granddaughter | $1.4 billion |
| Eduardo Voigt Schwartz | Grandson | $1.7 billion |
| Mariana Voigt Schwartz Gomes | Granddaughter | $1.7 billion |
According to reporting on the 2026 list, seven Voigt-family cousins appeared among Forbes’ billionaires that year, up from four the previous year, with a combined family fortune cited at around $9.5 billion. The variation in individual amounts likely comes down to which branch of the family, and which specific holding vehicle, each cousin’s shares flow through, though the exact reasons for the size differences between branches have not been detailed in available reporting.
Does Amelie Voigt Trejes Work at WEG?
No. According to Forbes, Amelie Voigt Trejes holds no board seat and no executive position at WEG. The same is true of her twin brothers. Her wealth is entirely a function of ownership, not employment or operating involvement in the company her grandfather helped build.
This is an important distinction for anyone assuming her net worth reflects a salary or business earnings. It doesn’t. It reflects the market value of shares she and her family hold, which rises and falls with WEG’s stock price regardless of anything she personally does.
WEG: The Company Behind the Fortune
WEG S.A. was founded on September 16, 1961, in Jaraguá do Sul, in the Brazilian state of Santa Catarina. Its name comes from the initials of its three founders: Werner Ricardo Voigt, Eggon João da Silva, and Geraldo Werninghaus, according to the company’s own corporate history.
What started as a small motor manufacturer has grown into one of the world’s larger producers of electric motors, generators, transformers, and industrial automation systems, with factories in more than ten countries, as described in Forbes’ profile of the company. Forbes reports WEG’s annual revenue at approximately $7 billion, and Brazilian financial media reported the company’s market capitalization at roughly R$210.8 billion based on B3 trading as of August 28, 2026.
WEG remains publicly traded, which is precisely why estimates of Amelie Voigt Trejes’s net worth shift over time. Her wealth is tied to a stock price that moves with the broader market, Brazilian economic conditions, currency fluctuations, and the company’s own quarterly results, not to a fixed inheritance amount that stays constant year to year.
Is Amelie Voigt Trejes the Youngest Billionaire in the World?
As of the 2026 Forbes World’s Billionaires list, yes. Forbes notes that she became the world’s youngest billionaire in 2026, surpassing Johannes von Baumbach, a German heir to the pharmaceutical company Boehringer Ingelheim, by about seven weeks in age, according to Forbes and corroborating coverage from La República.
The title has moved around within her own family recently. Her cousin, Lívia Voigt de Assis, held the “world’s youngest billionaire” distinction in 2024 at age 19, according to reporting on that year’s list. That history is worth knowing because it shows the title isn’t static. It shifts from year to year as new heirs cross the billion-dollar threshold and as previous titleholders age past younger newcomers.
Conclusion
Amelie Voigt Trejes’s story is a clear illustration of how generational wealth compounds inside a family-controlled public company. She didn’t found a business, run a company, or generate the fortune herself. She inherited a piece of WEG through her mother, Cladis Voigt, who was one of founder Werner Ricardo Voigt’s three children. As WEG’s share price has grown over the decades, that inherited stake, split among grandchildren and routed through family holding companies, turned into an estimated $1.1 billion fortune by early 2026, enough to make her, briefly, the youngest billionaire on the planet.
Her net worth will likely keep moving as WEG’s stock price does. What stays fixed is the structure underneath it: a founder’s stake, divided three ways, then divided again, sitting quietly in a company that keeps making electric motors.
