Livia Voigt of Brazil is the youngest billionaire in the world. She is still in college at the age of 19, but her estimated net worth is $1.1 billion since she owns a minority ownership in WEG, a company that produces electrical equipment and was co-founded by her late grandpa. She and her 26-year-old sister, Dora Voigt de Assis, are two of the 18 heirs and seven new faces among the 25 youngest billionaires.

Ireland’s Mistry brothers, who are 25 and 27 years old, are the richest of the heirs. They are valued at an estimated $4.9 billion each, due to the Mumbai-based Tata Sons group, which operates in the fields of energy, engineering, and information technology and communications. Following the passing of their father, Cyrus, in 2022, they were granted their minority ownership in Tata.

the Italian-French manufacturer of Ray-Bans. Along with three older siblings, he also inherited fortunes through his brothers Leonardo Maria, 28, and Luca, 22. Next is Sophie Luise Fielmann, a 29-year-old German heiress to the eyewear fortune of Fielmann AG, which was given to her by her father, Günther Fielmann, who passed away in January at the age of 84.

From oldest to youngest, these are the 25 youngest people on the World’s Billionaires list, all of whom are 33 years of age or younger.

Another explanation for the high number of heirs among extremely young billionaires: Many of the quintessential self-made young tycoons, like Mark Zuckerberg (39, United States) of Meta and Bobby Murphy (35), of Snap, have matured. No one is going to replace them. The only self-made newcomer among the 25 youngest this year is Shunsaku Sagami, a 33-year-old merger and acquisitions dealmaker from Japan whose business, M&A Research Institute Holdings, matches clients using artificial intelligence.

Since going public in June 2022, its stock has increased by more than 800%, propelling him into the billionaire ranks. Additionally, entrepreneurs that make riches early are not certain to keep them. Breslow, Ryan  was
