Pierre Casiraghi Net Worth

What is Pierre Casiraghi's Net Worth?

Pierre Casiraghi is a Monegasque businessman, sailor, and member of Monaco's princely family who has a net worth of $100 million. The youngest son of Princess Caroline of Monaco and the grandson of Grace Kelly and Prince Rainier III, Pierre combines inherited family wealth with active business interests and a successful career in international sailing.

Pierre is directly involved in businesses once associated with his late father, Stefano Casiraghi, including Monaco construction company Engeco and helicopter operator Monacair. He is also vice president of the Yacht Club de Monaco and co-founded Team Malizia, the offshore racing organization he established with German sailor Boris Herrmann in 2016.

Through Team Malizia, Casiraghi has competed in major international sailing events while using the sport to promote ocean conservation and climate research. He is married to Italian journalist, filmmaker, and aristocrat Beatrice Borromeo.

Early Life and Family Background

Pierre Rainier Stefano Casiraghi was born on September 5, 1987, in Monaco. He is the youngest child of Princess Caroline and Italian businessman and offshore powerboat racer Stefano Casiraghi.

His older siblings are Andrea Casiraghi and Charlotte Casiraghi. He also has a younger half-sister, Princess Alexandra of Hanover, from his mother's marriage to Prince Ernst August of Hanover.

Through Andrea's marriage, Pierre's sister-in-law is billionaire beer heiress Tatiana Casiraghi, a member of Colombia's enormously wealthy Santo Domingo family.

Pierre was only three years old when his father was killed in a powerboat racing accident off Monaco in October 1990. Seeking privacy for her children after Stefano's death, Princess Caroline moved the family away from Monaco for much of their childhood, first to Saint-Rémy-de-Provence and later to Fontainebleau.

Education and Business Career

Casiraghi studied international economics and management at Bocconi University in Milan after completing his earlier education in France.

His business career has significant connections to his father's legacy. Stefano Casiraghi founded Engeco, a Monaco-based construction company, in the 1980s and held a majority interest in the business. Pierre later became its majority shareholder, while his uncle Marco Casiraghi continued serving in a leadership role.

Pierre also became a major shareholder in Monacair, the Monaco helicopter company that provides passenger transportation and charter services throughout the region.

These holdings make Pierre somewhat unusual among the younger members of Monaco's princely family. While his family connections are obviously significant, a meaningful portion of his wealth is tied to privately held operating businesses rather than simply a royal allowance or ceremonial position.

Family Wealth and Inheritance

Pierre Casiraghi was born into substantial wealth on both sides of his family.

His maternal grandparents were Prince Rainier III, who transformed Monaco into one of the world's wealthiest and most glamorous principalities, and Academy Award-winning actress Grace Kelly. His mother, Princess Caroline, has a net worth of $100 million.

Pierre's father, Stefano Casiraghi, also came from an affluent northern Italian business family. Stefano worked in his family's real estate and commercial businesses and became a successful businessman in his own right. Among his interests were Engeco and the French construction company Cogefar France.

Stefano died at just 30 years old, leaving behind Princess Caroline and their three young children. The exact value and distribution of his estate have never been publicly disclosed. Over the years, some publications and online accounts have assigned enormous values to Stefano's fortune, but there is no reliable public evidence establishing that his personal estate was worth multiple billions of dollars.

What is clear is that Pierre inherited more than simply a famous surname. His eventual control of important Casiraghi family business interests, including Engeco and Monacair, provides a tangible connection between the wealth created by his father's family and Pierre's present-day fortune.

Combined with inherited investments and other private family assets, Pierre's business holdings support a net worth of $100 million.

Sailing and Team Malizia

Pierre inherited his father's passion for high-speed competition on the water, although he chose sailing rather than offshore powerboat racing.

He has competed in events including the Palermo-Monte Carlo regatta and the Giraglia Rolex Cup. In 2016, Pierre and Boris Herrmann founded Team Malizia, an offshore sailing team based around the Yacht Club de Monaco.

Team Malizia evolved into an internationally prominent racing and environmental organization. In addition to competing in major ocean races, its boats have carried scientific equipment that collects data about carbon dioxide and ocean conditions.

One of Pierre's most publicized sailing projects came in 2019, when Team Malizia transported climate activist Greta Thunberg across the Atlantic aboard the racing yacht Malizia II. Herrmann skippered the voyage, while Pierre played a central role in organizing the project.

Team Malizia celebrated its tenth anniversary in 2026.

Personal Life

While studying in Milan, Pierre met Beatrice Borromeo, a journalist, documentary filmmaker, and member of the aristocratic Borromeo family. Her family has held extensive property in northern Italy for centuries, including islands in Lake Maggiore.

Pierre and Beatrice married in a civil ceremony at Monaco's Prince's Palace in July 2015, followed by a religious wedding on the Borromean Islands.

They welcomed their first son, Stefano, in 2017 and their second son, Francesco, in 2018. Their third child and first daughter, Bianca Caroline Marta Casiraghi, was born in October 2025.

Pierre remains active in Monaco's public life and serves as vice president of the Yacht Club de Monaco. Although he does not hold a royal title, he remains in the line of succession to the Monegasque throne.
