Bernard Arnault's net worth is estimated at around $140-150 billion, according to Forbes' July 2026 Real-Time Billionaires List, ranking him roughly ninth in the world -- down substantially from a peak of about $240.7 billion in April 2023, when he briefly overtook Elon Musk as the world's richest person. His fortune is built almost entirely on LVMH, the luxury conglomerate he has led since 1989.
Arnault has held the title of world's richest person multiple times, including briefly in December 2019, again in August 2021, and at his April 2023 peak. He has increasingly handed control of individual LVMH brands to his five children, positioning the company's next generation of leadership.

Early Life
Bernard Arnault was born on March 5, 1949, in Roubaix, France, the son of a civil engineering company owner. He studied at the Ecole Polytechnique before joining his father's company in 1971, later converting it into a real estate business, Ferinel, which he led as president from 1979.
Building LVMH
In 1984, Arnault acquired the luxury holding company Financiere Agache and took control of the struggling textile group Boussac Saint-Freres, which included Christian Dior, selling off most of its other assets. He became a major shareholder of the newly merged Louis Vuitton Moet Hennessy (LVMH) in the late 1980s, building his stake through a series of investments before becoming chairman of its executive board in 1989. Under his leadership, LVMH grew through acquisitions including Celine, Fendi, Sephora, Marc Jacobs, Loewe, and Tiffany & Co., becoming the world's largest luxury goods company.
World's Richest Person
Arnault has held the title of world's richest person on several occasions, briefly surpassing Jeff Bezos in December 2019 and January 2020, then Elon Musk in August 2021 with a net worth of about $198.4 billion. He reached his personal peak of roughly $240.7 billion in April 2023, again ahead of Musk, before LVMH's stock declined amid slowing luxury demand, pulling his fortune down to its current level.
Family Succession at LVMH
All five of Arnault's children now hold senior positions within LVMH. Daughter Delphine Arnault, from his first marriage, became CEO of Christian Dior in February 2023. Among his children with second wife Helene Mercier: Alexandre serves as executive vice president of Tiffany & Co., Frederic is CEO of LVMH Watches, and Jean holds a marketing and development role in watchmaking at Louis Vuitton. Son Antoine also holds a senior role within the group.
Other Ventures
In November 2024, the Arnault family acquired majority ownership of French football club Paris FC, which was subsequently promoted to Ligue 1 for the first time in 46 years. In February 2026, the family increased its LVMH ownership stake to just over 50%, controlling nearly two-thirds of the company's voting rights.
Personal Life
Arnault was married to Anne Dewavrin from 1978 to 1990, with whom he has two children, Delphine and Antoine. He has been married to pianist Helene Mercier since 1991, with whom he has three sons: Alexandre, Frederic, and Jean.
