What Is Athina Hélène Onassis’ Net Worth?

Athina Hélène Onassis, a prominent figure in both the equestrian world and as the sole surviving heir to the vast Aristotle Onassis shipping fortune, boasts a significant net worth. Currently, Athina Onassis’ net worth is estimated to be around $1 billion. This substantial wealth is primarily derived from her inheritance as the granddaughter of Aristotle Onassis, the legendary Greek shipping magnate. While her family’s wealth has provided a solid foundation, Athina has also carved out her own identity as a competitive show jumper.

Athina Onassis: Equestrian Career and Ventures

Athina Onassis’ involvement in equestrian sports began during her teenage years, initially known as Athina Roussel. Over time, she reconnected with her Greek heritage, adopting her Greek last name and learning the Greek language. Her dedication to show jumping led her to participate in the prestigious Global Champions Tour, where she showcased her skills as a competitive rider. She has also been a patroness of the competition, supporting the sport and its athletes. In 2007, Athina established the Athina Onassis International Horse Show in São Paulo, which later moved to Rio de Janeiro in 2009 and Saint-Tropez in 2014. This event has become a prominent fixture in the equestrian calendar, attracting top riders and horses from around the world. In 2012, Athina suffered a spinal injury following a fall from her horse, but she recovered and competed in the European Show Jumping Championships the following year. She also participated in the 2014 World Championships, demonstrating her resilience and commitment to the sport. Furthermore, Athina and her former husband, Álvaro de Miranda Neto, co-owned AD Sport Horses, a Belgium-based business focused on breeding and training horses. This venture further solidified her presence in the equestrian industry, contributing to Athina Onassis’ net worth.

The Onassis Estate and Inheritance

Athina Onassis’ inheritance is a complex matter, involving a substantial fortune and a trust fund controlled by a board of directors at the Onassis Company. Her mother, Christina Onassis, inherited 55% of the Onassis fortune, while the remaining 45% (minus the $26 million received by Jacqueline Kennedy Onassis) was bequeathed to the Alexander S. Onassis Foundation, established in honor of Aristotle’s son, who tragically died in a plane crash in 1973. Due to Christina’s reservations about Thierry Roussel, Athina’s father, the family arranged for the Onassis estate to be managed by a board of administrators until Athina reached legal age. Christina appointed Paul Ioannidis, Theodore Gabrielides, Stelio Papadimitriou, and Apostolos Zabelas as trustees, who were responsible for approving any expenditures made by Roussel on Athina’s behalf during her youth. In 1999, a court in Vaduz, Liechtenstein, ruled that the management of Athina’s inheritance be transferred to the Switzerland auditing firm KPMG Fides. Athina gained control of the inheritance on her 18th birthday. After turning 21, her lawyers attempted to have her instated as President of the Onassis Foundation, but their efforts were unsuccessful. Stelio Papadimitriou, the Foundation’s President at the time, expressed concerns about Athina’s lack of connection to Greek culture, religion, language, and shared experiences, as well as her lack of formal education and work experience. Despite these challenges, Athina Onassis’ net worth remains significant, largely due to her inheritance.

Early Life and Family Background

Athina Hélène Onassis was born on January 29, 1985, in Neuilly-sur-Seine, France. Her mother, Christina Onassis, was a Greek heiress, socialite, and businesswoman, while 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. Tragically, Christina passed away from pulmonary edema in 1988, when Athina was only 3 years old. Athina was subsequently raised by her father and Landhage, who he married in 1990. She attended school in Lussy-sur-Morges, Switzerland, and completed a preparatory course in Brussels, Belgium. In 2003, she passed her baccalauréat exam. Athina has a half-brother, Erik, and two half-sisters, Sandrine and Johanna. Her grandfather, Aristotle Onassis, was one of the wealthiest men in the world, and his marriage to Jacqueline Kennedy brought her $26 million from his estate upon his death. The Onassis family’s history and wealth have undoubtedly shaped Athina Onassis’ life and contributed significantly to Athina Onassis’ net worth.

Personal Life and Relationships

Athina Onassis’ personal life has been marked by both joy and sorrow. In 2003, she began a relationship with Brazilian show jumper/Olympic medalist Álvaro de Miranda Neto. She purchased an $8.6 million, 10,600 square foot home in São Paulo. The couple married on December 3, 2005, but their marriage ended in a legal separation in 2016, following allegations that Álvaro had been involved with another woman for eight years of their 11-year marriage. Miranda reportedly sought 11 million euros in the divorce (based on their prenuptial agreement) and “350,000 euros for alimony, payment for their joint ventures, as well as custody of their horses and properties with a total value of 400,000,000 dollars.” The divorce was finalized in late 2017, with Álvaro receiving “almost nothing.” During their marriage, Onassis was stepmother to Viviane, Miranda’s daughter with model/actress Cibele Dorsa, and Fernando, Dorsa’s son from a previous relationship. Cibele had agreed to let her children live with Athina and Álvaro so they could have a “very simple and healthy lifestyle.” After Cibele’s fiancé, Gilberto Scarpa, died in an apparent suicide in early 2011, Dorsa posted on social media, “To live without my two children and without the love of my life has wounded my whole self.” Tragically, in March 2011, Cibele took her own life by jumping from a window of her São Paulo apartment building. These personal experiences have undoubtedly impacted Athina’s life, but they have not diminished her financial standing or Athina Onassis’ net worth.

Real Estate and Investments

Athina Onassis has made strategic investments in real estate, further contributing to her wealth. In 2014, she purchased a horse farm in Wellington, Florida, for $12 million and sold the 5.62-acre property for $12.75 million in 2017, realizing a profit on the sale. In 2013, Athina sold the Greek island of Skorpios to Russian billionaire Ekaterina Rybolovleva. Although the exact sale price remains undisclosed, it is rumored to be around $150 million. Aristotle Onassis acquired Skorpios in 1963 for 3.5 million drachmas (equivalent to approximately $12,000 today). The island holds significant sentimental value as the burial site of Aristotle, Christina, and Alexander Onassis. These real estate transactions demonstrate Athina’s business acumen and contribute to the maintenance and growth of Athina Onassis’ net worth.
