His portfolio encompasses iconic brands such as Louis Vuitton, Tiffany & Co., and Dom Pérignon. A significant portion of his wealth is attributed to his 97.5% ownership in Christian Dior, a flagship entity within the LVMH group. In a notable move reflecting his vision for the company's future, Arnault appointed his daughter, Delphine Arnault, as the CEO and chair of Dior in 2023, further solidifying the family's influence within the luxury sector. This decision underscores Arnault's commitment to legacy and innovation, as all four of his other children play integral roles within LVMH and its array of prestigious brands. Arnault's decision in 2022 to extend the company's mandatory retirement age to 80 underscores his dedication to his empire and provides him additional time to strategize the succession of his luxury conglomerate, ensuring the continued growth and prominence of LVMH in the luxury market.
