Net Worth $3 billion
Athina Onassis, sole surviving heir to Aristotle Onassis’ shipping fortune, has a net worth of $3 billion. Her net worth is largely as a result of her famously wealthy family, but Onassis has made a name for herself as a competitive show jumper. Her career in the world of equestrian sport began as a teenager, when she was still known as Athina Roussel. Since then, she’s attempted to explicitly reconnect with her Greek heritage by reinstating her Greek last name and learning the Greek language. Onassis has also had a notable personal life, having already been married and divorced even though she’s only 26 years old.
