Money at nineteen. Can you even imagine? While most teenagers are busy arguing over who's paying for the pizza or figuring out how to survive a freshman-year psychology lecture, Livia Voigt is technically the youngest richest woman in the world. But here’s the thing—the headlines usually miss the nuance. People see the "billionaire" tag and think of boardrooms and power suits, yet the reality is much more low-key.
Honestly, the world of ultra-high net worth youth is split into two very different camps. You have the heirs, like Livia, who are basically living the most high-stakes version of "trust fund" life imaginable. Then you have the self-made outliers like Lucy Guo, who basically willed her way into the ten-figure club through sheer tech-savvy and a willingness to break things.
If you're looking for the "richest" in terms of pure age-to-dollar ratio, the names on the list might surprise you. It’s not just about who has the most; it’s about how they got it and what they’re actually doing with it in 2026.
The Heir Apparent: Livia Voigt and the WEG Legacy
Livia Voigt is nineteen. She lives in Brazil. According to the latest 2026 data, she’s sitting on a net worth of roughly $1.2 billion.
Where did it come from? It’s all tied up in WEG, which is a massive industrial conglomerate that makes electric motors. Her grandfather, Werner Ricardo Voigt, co-founded the thing. Livia owns about 3.1% of the company.
Now, if you’re picturing her running meetings or deciding on international expansion strategies, you’ve got it wrong. She’s currently a university student. She doesn't have a seat on the board. She doesn't even have an executive role. She is essentially a student with a really, really high-performing stock portfolio.
The Rest of the Heir List
Livia isn't the only one in this boat. The "young and rich" club is dominated by people who inherited the keys to the kingdom:
- Clemente Del Vecchio: He’s often mentioned in the same breath as Livia. He’s the heir to the Luxottica fortune (think Ray-Ban and Oakley). While he’s slightly older than Livia, his net worth is actually much higher—clocking in at over $7 billion.
- Kim Jung-youn: Hailing from South Korea, she’s around twenty-two and inherited a massive stake in Nexon, the gaming giant, after her father passed away. Her net worth hovers around $1.9 billion.
- Dora Voigt de Assis: Livia’s older sister (26) is also a billionaire for the exact same reason.
It’s a weird existence. You’re one of the most powerful people on paper, but in reality, you’re just trying to get through your twenties without the world watching every move you make on Instagram.
The Self-Made Titan: How Lucy Guo Reached the Top
If the heirs are the "quiet" side of wealth, Lucy Guo is the loud, frantic, and fascinating opposite. In 2025, she officially unseated Taylor Swift to become the world’s youngest self-made female billionaire. As of 2026, she is the definitive blueprint for how a young woman can build a ten-figure fortune from scratch in the AI era.
Lucy’s story isn't about inheritance. It’s about being a "Silicon Valley rebel." She was a Thiel Fellow (the program that pays you $100k to drop out of college). She co-founded Scale AI with Alexandr Wang, but eventually left after some co-founder friction.
She kept a 5% stake in Scale AI. When Meta acquired a massive chunk of the company at a $25 billion valuation, Lucy’s paper wealth exploded.
What makes her different?
She’s a "builder." She didn't just sit on her Scale AI shares and retire to a beach. She started Passes, a creator monetization platform that’s currently taking a bite out of the market share of older platforms like OnlyFans, but with a stricter "no nudity" policy.
She also lives this bizarrely contradictory life. She recently bought a $30 million mansion in the Hollywood Hills, but she openly talks about being part of the FIRE (Financial Independence, Retire Early) movement. She’s been known to drive a Honda Civic and shop at Shein.
It’s this "hacker" mindset that resonates. She’s not just the youngest richest woman in the self-made category; she’s an active participant in the tech economy.
The New Guard: Luana Lopes Lara and the Prediction Market
Another name you need to know in 2026 is Luana Lopes Lara. She’s the co-founder of Kalshi, the first federally regulated exchange for "event contracts." Basically, it’s a place where you can bet on—or "hedge against"—real-world events like Fed interest rate hikes or movie box office numbers.
Forbes recently flagged her as a rising titan in the self-made category. While her net worth is still fluctuating based on Kalshi’s private valuation, she represents a shift. We’re moving away from "social media" wealth and toward "deep infrastructure" and "fintech" wealth.
Luana and Lucy represent a trend: young women aren't just becoming rich through "lifestyle" brands. They are building the plumbing of the internet and the financial markets.
Why This Matters for You
You might think, "Cool, some people have billions. How does that help me?"
Looking at the youngest richest women in the world actually reveals some pretty solid "real world" lessons if you look past the zeros.
- Equity is Everything: Lucy Guo became a billionaire because she held onto her 5% stake in Scale AI even after she left. If she had sold early, she’d "only" be a multi-millionaire. The real wealth is in ownership, not salary.
- The Great Wealth Transfer is Real: Livia Voigt is a symbol of what economists call the "Great Generational Wealth Transfer." Trillions are moving from Baby Boomers to Gen Z. If you're in business, you need to realize that the "owners" of the world are getting younger and have very different values.
- The "Frugal Billionaire" Paradox: There is a weird trend among these young billionaires to stay "low-profile" or "frugal." Whether it’s Livia staying in a dorm or Lucy driving a Honda, the new rich seem to value "optionality" over "gaudiness."
Actionable Takeaways for Building Your Own Path
You don't need a billion dollars to use the strategies these women used to get (and keep) their positions.
- Audit Your Ownership: Are you working for a paycheck, or are you building equity? If you’re an early employee at a startup, those stock options are your only real shot at "outlier" wealth.
- Solve "Plumbing" Problems: Notice how these women are in electric motors (WEG), AI data labeling (Scale AI), and event trading (Kalshi). They aren't just making "stuff"—they are building the systems other people use.
- Vary Your Hustle: Lucy Guo started by selling Neopets items as a kid. Small hustles build the "muscle" for big ventures later. Don't be afraid to start small and weird.
The youngest richest woman in the world title will likely change hands again by 2027. But the gap between the heirs and the builders is widening. Whether you're rooting for the quiet student in Brazil or the rebel coder in Hollywood, one thing is clear: the face of global wealth is younger, female, and a lot more tech-obsessed than it used to be.
Next Steps for You: Start by researching "equity-based compensation" if you're in the job market. If you're an entrepreneur, look into the "creator economy infrastructure" space—it's where the next wave of self-made wealth is being generated right now.
