Top 10 Youngest Female Billionaires of 2025

The world of wealth is always changing, and the list of the youngest female billionaires in 2025 has some new names. Changes in different industries show how the world of wealth keeps shifting. 

At just 20 years old, Livia Voigt is now the youngest female billionaire, holding a $1.2 billion stake in WEG, which is the biggest maker of electrical motors in Latin America.

In South Korea, the sisters Kim Jung-youn and Kim Jung-min each have $1.3 billion from their shares in the gaming company Nexon. In Norway, the Andresen sisters, Alexandra and Katharina, each have $1.5 billion from their family’s investment firm, Ferd.

The 2025 list no longer includes well-known names like Rihanna, Melanie Perkins, and Ginia Rinehart. This has made space for these new and continuing young women who are involved in everything from gaming and entertainment to manufacturing. 

These women have built their wealth through inherited money and their business ventures.
