At just 20 years old, Amelie Voigt Trejes has captured worldwide attention after emerging as the youngest billionaire in the world in 2026. Her estimated fortune comes from an inherited stake in WEG, a major Brazilian industrial company founded by her grandfather, Werner Ricardo Voigt. Unlike many young billionaires, Amelie didn’t build a startup or chase fame. Her story centers on family ownership, long-term business growth, and generational wealth.
The latest figures put Amelie Voigt Trejes net worth at around $1 billion to $1.1 billion, depending on the valuation date. Her fortune makes her a fascinating example of inherited wealth, while her quiet public profile adds another layer to her story. Here’s a closer look at her Amelie Voigt Trejes wealth, family background, WEG connection, and remarkable rise to billionaire status.
Amelie Voigt Trejes Net Worth and Wealth in 2026
The latest Forbes profile places Amelie at about $1 billion in real-time wealth as of July 27, 2026. Forbes’ March 2026 annual list valued her at $1.1 billion. That difference matters because a billionaire net worth estimate can move with a company’s share price.
Her Amelie Voigt Trejes wealth is tied mainly to WEG shares. Forbes says she owns about 2% of WEG. The company remains a publicly traded industrial leader, meaning the market continually changes the value attached to her ownership stake.

Who Is Amelie Voigt Trejes?
At the center of every Amelie Voigt Trejes biography is a simple fact: she became extraordinarily wealthy through her family’s industrial holdings. Forbes identifies her as a Brazilian citizen and lists her residence as Florianópolis, Brazil. Her public profile remains unusually quiet for someone with a billion-dollar fortune.
The Amelie Voigt Trejes family has deep roots in Brazil’s manufacturing economy. Her grandfather helped establish WEG in 1961. Her mother, Cladis Voigt Trejes, later passed WEG-related ownership to Amelie and her brothers. That family transfer explains why this Brazilian billionaire entered the global wealth rankings so young.
Why Amelie Voigt Trejes Became Famous
The Amelie Voigt Trejes Forbes story gained attention because age made her ranking unusual. Forbes’ 2026 list included 35 billionaires under 30. Amelie became the youngest of them at 20, while most young fortunes still came through inheritance.
How Amelie Voigt Trejes Became a Billionaire
Amelie’s fortune traces back to Amelie Voigt Trejes inheritance, rather than a company she personally founded. Forbes reports that her grandfather, Werner Ricardo Voigt, co-founded WEG in 1961. Her mother later transferred part of her WEG holdings to Amelie and her two brothers.
This is a classic example of billionaire inheritance creating a new generation of wealth. The underlying asset isn’t simply cash. It is an ownership interest in a major company. When that company grows, the value of the inherited shares can grow too.
From Family Shares to a Billion-Dollar Fortune
Amelie is therefore better described as an inherited billionaire than a self-made entrepreneur. Her fortune demonstrates how family business wealth can compound over decades. WEG started with three founders. Its modern value now supports fortunes across several branches of their families.
The Story of WEG and Its Role in Her Fortune
WEG, formally WEG S.A., began in Jaraguá do Sul in Santa Catarina on September 16, 1961. The original company combined the skills of an electrician, an administrator, and a mechanic. It initially focused on electric motors before expanding into broader electrical and industrial products.
Today, the WEG company operates across global industrial markets. Its portfolio includes generators, transformers, drives, gearboxes, electrification products, automation systems, and digital solutions. WEG reported 2025 net operating revenue of BRL 40.8 billion.
How WEG Built the Family Fortune
The modern WEG ownership structure shows why the founder families remain important. As of April 23, 2026, WPA Participações held 50.09% of WEG. Founder-family members also directly held another 14.27%. That structure demonstrates the continuing importance of family ownership.
Amelie Voigt Trejes’ Early Life and Education
Reliable information about Amelie’s private childhood remains limited. That restraint is important. Public records and major financial profiles provide fewer personal details than you might expect from a young billionaire. Forbes confirms her age, citizenship, wealth source, and residence.
Her Amelie Voigt Trejes age was 20 when Forbes named her the youngest billionaire 2026. Claims about lecture halls, university routines, or private habits should therefore be treated carefully unless independently verified. Wealth does not automatically make every personal detail public.
A Young Life Beside an Extraordinary Fortune
Being a university student billionaire creates a striking contrast. Most people at 20 are still building credentials and exploring career options. Amelie already owns an interest in a major manufacturing company, yet Forbes says she has no executive or board role at WEG.
Amelie Voigt Trejes’ Family, Parents, and Siblings
Her family story explains more about her fortune than any personal career achievement. Forbes and Brazilian financial coverage identify her mother as Cladis Voigt, who transferred WEG-related shares to Amelie and her brothers. This family structure illustrates how inherited fortune can divide between several descendants.
Her brothers Pedro Voigt Trejes and Felipe Voigt Trejes also appear on Forbes’ 2026 young-billionaire list. Each was valued at roughly $1.1 billion in that ranking. They are major WEG shareholders, although Forbes says they don’t hold executive roles at the company.
A Family of Billionaire Shareholders
These billionaire siblings show how one industrial asset can create several fortunes. The wider billionaire family also includes other relatives tied to WEG. Forbes’ profiles connect several billionaire cousins and family members to the same financial asset.
Werner Ricardo Voigt and the Family’s WEG Legacy
Werner Ricardo Voigt was one of the three original WEG founders. He built the company’s technical foundation alongside Eggon João da Silva and Geraldo Werninghaus. WEG’s own history describes how their combined skills created the original Eletromotores Jaraguá in 1961.
Werner died in 2016 at age 85. His legacy, however, continued through company ownership and later generations. The WEG founding families still hold substantial influence through the corporate structure. That connection gives Amelie’s fortune a distinctly multigenerational character.
From Founder to Future Generations
The Voigt family fortune didn’t appear overnight. It grew from industrial production, international expansion, and long-term corporate ownership. Amelie’s story shows how a successful founder can create financial security that reaches grandchildren decades later.
Is Amelie Voigt Trejes a Self-Made or Inherited Billionaire?
Amelie is best classified as an inherited billionaire. Her wealth came through WEG-related holdings passed through her family rather than through founding a company herself. Forbes’ 2026 coverage makes that distinction clear when it describes her as an heir to WEG.
The distinction matters because billionaire rankings increasingly separate entrepreneurial fortunes from inherited fortunes. Forbes reported that 67% of global billionaires in its 2026 list were self-made. Among the 35 under-30 billionaires, however, most inherited their wealth.
Amelie Versus a Self-Made Billionaire
A passive billionaire can still own an extremely valuable asset without managing the underlying business. Amelie fits that pattern. She is a billionaire shareholder, while WEG’s professional leadership runs day-to-day operations.
Amelie Voigt Trejes Compared With Other Young Billionaires
The 2026 Forbes ranking places Amelie at the top of the youngest-billionaire group. She was three weeks younger than Johannes von Baumbach, according to Forbes’ published comparison. That small age gap decided who received the world’s youngest billionaire title.
The broader group reveals an interesting divide. Some youngest billionaires inherited huge family stakes. Others built fast-growing companies in technology or artificial intelligence. Forbes counted 35 billionaires under 30 with combined wealth of $92.4 billion.
Young Billionaires Under 30
The group of young billionaires under 30 includes heirs from pharmaceuticals, gaming, eyewear, and industrial machinery. It also includes newer founders whose fortunes came from AI and prediction markets. Amelie’s path therefore represents one important route to wealth, not the only one.
Amelie Voigt Trejes’ Lifestyle, Career, and Public Life
Despite her fortune, Amelie remains a private billionaire. Forbes says she doesn’t hold a board seat or executive position at WEG. That fact separates her from many wealthy heirs who actively participate in family companies. Her public profile is mainly financial rather than celebrity-driven.
Her lifestyle should not be exaggerated. Public wealth estimates don’t reveal someone’s spending habits. A large billion-dollar fortune can exist mainly through shares, holdings, and long-term assets. In Amelie’s case, the available evidence points toward ownership rather than a highly visible public career.
A Quiet Public Profile
Unlike many young wealthy personalities, Amelie hasn’t built a public brand around her fortune. That makes her different from celebrity entrepreneurs. She became famous through a billionaire ranking, not social media, entertainment, or a high-profile startup.
Amelie Voigt Trejes’ Future Wealth and Business Outlook
Amelie’s future financial position will depend heavily on WEG and the value of related family holdings. WEG’s 2025 results show substantial revenue and strong returns on invested capital. Its continued international expansion could support future value creation, although stock prices can move sharply in either direction.
That makes the future of Amelie Voigt Trejes net worth less predictable than a salary calculation. Her wealth can rise when WEG appreciates. It can also fall when markets weaken. Currency movements, corporate results, dividends, and changes in ownership can all influence her estimated fortune.
What Her Story Says About Generational Wealth
Amelie’s case is a clear example of wealth transfer across generations. A company created in 1961 can still shape the financial lives of descendants today. That is the power of generational fortune. The asset survives because ownership survives, while the business continues creating new value.
WEG’s official ownership data confirms that founder families remain major shareholders. Its controlling structure includes WPA Participações, while direct founder-family ownership remains significant. This gives the family wealth a durable corporate foundation rather than relying solely on inherited cash.
Conclusion
The story behind Amelie is ultimately bigger than a number. She represents a new generation of heirs whose fortunes rest on businesses built long before they were born. Her family inheritance, WEG stake, and age explain why she became such a remarkable entry on the global wealth map.
As of the March 2026 Forbes list, Amelie Voigt Trejes net worth stood at an estimated $1.1 billion. Forbes’ later real-time profile showed about $1 billion in July. Those figures can change, but the central story remains: a 20-year-old Brazilian heir became the youngest billionaire through one of her country’s most successful industrial companies.
