What is Athina Onassis’ Net Worth?

Athina Onassis is a French-Greek heiress and equestrian with a net worth of $1 billion. She is the sole surviving heir to the Aristotle Onassis shipping fortune, and her wealth is largely due to her famously wealthy family. Onassis has made a name for herself as a competitive show jumper, starting her career as a teenager under the name Athina Roussel.

Onassis has attempted to reconnect with her Greek heritage by reinstating her Greek last name and learning the Greek language. However, she has faced legal issues regarding her inheritance, which was locked up in a trust fund controlled by a board of directors at the Onassis Company.

Despite some media outlets questioning her net worth, Onassis is still widely considered a billionaire. Her financial future is secure, barring any unforeseen economic collapse.

Athina Onassis was born in Neuilly-sur-Seine, France in 1985. Her mother, Christina, was a Greek heiress, socialite, and businesswoman, and her father, Thierry Roussel, is a French pharmaceutical heir. Christina and Thierry divorced in 1987 after Roussel fathered two children with model Marianne “Gaby” Landhage. Onassis was then raised by her father and Landhage, who he married in 1990.

Athina attended school in Switzerland and Belgium, passing her baccalauréat exam in 2003. She has a half-brother, Erik, and two half-sisters, Sandrine and Johanna. Her grandfather, Greek shipping magnate Aristotle Onassis, was one of the richest men in the world; he was married to Jacqueline Kennedy at the time of his death, and she reportedly received $26 million from his estate.

Athina Onassis’ Equestrian Achievements

Athina Onassis began horse riding in her childhood and was the runner-up at an event in Jerez, Spain in 2001. She participated in the Global Champions Tour as a competitive show jumper and also served as a patroness of the competition. In 2007, she established the Athina Onassis International Horse Show in São Paulo, which later moved to Rio de Janeiro in 2009 and Saint-Tropez in 2014. Despite suffering a spinal injury from falling off her horse in 2012, Onassis competed in the European Show Jumping Championships the following year. She also took part in the 2014 World Championships. Onassis and her former husband, Álvaro de Miranda Neto, co-owned AD Sport Horses, a Belgium-based business dedicated to breeding and training horses.

Athina Onassis’ Marriage and Divorce

Athina Onassis, the granddaughter of Greek shipping magnate Aristotle Onassis, married Brazilian show jumper/Olympic medalist Álvaro de Miranda Neto in 2005. They legally separated in 2016 after allegations arose that Álvaro was involved with another woman. The divorce was finalized in late 2017, with Álvaro reportedly getting “almost nothing” despite asking for 11 million euros and custody of their horses and properties with a total value of $400 million. During the marriage, Athina was stepmother to Álvaro’s children from a previous relationship. Tragically, in 2011, Cibele Dorsa, the mother of Álvaro’s children, committed suicide after her fiancé died.

Athina Onassis’ Inheritance and Attempted Presidency

Athina’s mother inherited 55% of the Onassis fortune, while the remaining 45% was given to the Alexander S. Onassis Foundation. The foundation was controlled by a board of administrators until Athina reached legal age. In 1999, management of her inheritance was transferred to the Switzerland auditing firm KPMG Fides. Athina attempted to become President of the Onassis Foundation after turning 21, but her lack of qualifications was cited as a reason for denial. Her stepmother claimed that Athina had once expressed a desire to burn all the Onassis money.

Athina Onassis’ Real Estate Deals

In 2014, Athina Onassis purchased a horse farm in Wellington, Florida for $12 million. Three years later, she sold the 5.62-acre property for $12.75 million.

In 2013, Athina sold the Greek island of Skorpios to Russian billionaire Ekaterina Rybolovleva for a rumored price of around $150 million. The island was originally purchased by Athina’s grandfather, Aristotle Onassis, for 3.5 million drachmas (which is equivalent to around $12,000 today) in 1963. Aristotle, as well as Athina’s mother Christina and brother Alexander, are buried on the island.
