2. Marta Ortega-Perez
Daughter of: Amancio Ortega
Ranking on the Forbes list: No. 5
Father’s net worth: $37.5 billion
You could mistake her for a model, but Marta Ortega-Perez is poised for bigger things. Her father Amancio Ortega is the founder of Inditex, an international fashion firm that owns the popular Zara label. It is expected that Marta will eventually be taking over the reins. The 28-year-old, who is currently married to star equestrian Sergio Alvarez Moya, is currently being groomed for the top job. But unlike other billionaire kids who smoothly step into their parents’ shoes, Marta started right at the bottom. She has stocked shelves, dealt with customers and is slowly earning her way to the top spot.
