Here are twelve of the world's youngest billionaires — and how they got their money

Net worth: $5.1 billion each

Irish citizens Firoz, 27, and Zahan, 25, are the richest entries on this list. Their 4.6% stakes in Indian conglomerate Tata Sons pushed both of their net worths over $5 billion in 2024.

Tata Sons owns over 100 companies and generates about $150 billion. The brothers received their inheritance after their 54-year-old father and 93-year-old grandfather died within months of each other in 2022.

Net worth: $4.8 billion

Del Vecchio is the 29-year-old son of Leonardo Del Vecchio, the Italian founder of eyewear brand EssilorLuxottica and former chair of Ray-Ban until his death in 2022. Upon their father's death, Del Vecchio and his six siblings each inherited a 12.5% stake in the family's holding company. This helped his younger brothers achieve a place on the list, too.

Luca Del Vecchio is the second Del Vecchio brother to make the youngest billionaire list in 2024. Like his older brother, he inherited a 12.5% stake in the family business when their father died in 2022.

At 22 years old, he's one of the richest and youngest on the list.

Clemente Del Vecchio is the youngest of the Italian brothers on the under-30 list at 20 years old. He was only two months shy of being declared the youngest billionaire in the world by Forbes. He also owns a 12.5% stake in his family's eyewear empire.

Net worth: $3.2 billion

Kevin David Lehmann once held the title of the world's youngest billionaire at just 18 years old. Now, at 21, he's still on the list. In 2021, he inherited his money from stakes in a German drugstore chain transferred to him by his father.

Net worth: $2.5 billion

When his father died in 2021, 23-year-old Remi Dassault inherited about 2.5% of the French software company Dassault Systèmes and 4.1% of Dassault Aviation, according to Forbes.

Sisters Kim Jung-min, 22, and Kim Jung-youn, 20, each hold 9% of Nexon, the South Korean-Japanese gaming company their father founded in 1994, Forbes reported. They inherited their stakes when their father died in 2022.

Net worth: $1.5 billion and $1.6 billion

The Andresen family first built its wealth in the tobacco industry. After their father sold the cigarette business in 2005, their attention turned to their multibillion-dollar investment firm Ferd, Forbes reported.

Norwegian sisters Alexandra, 28, and Katharina, 29, both own 42% stakes in Ferd, which has made their reported net worths $1.5 billion and $1.6 billion, respectively. Ferd invests in real estate, oil service business Interwell, and the largest private medical laboratory in Norway, according to Forbes.

Net worth: $1.1 billion each

Livia Voigt is the youngest billionaire in 2024 at 19 years old with a net worth of $1.1 billion. She and her sister, 26-year-old Dora Voigt de Assis, who also has a net worth of $1.1 billion, are the granddaughters of Brazilian billionaire Werner Ricardo Voigt.

Their late grandfather cofounded WEG, an electrical equipment producer; each woman owns 3.1%. Neither of them work at the company.
