Bernard Arnault Joins X Amid LVMH Family Succession Scrutiny

LVMH chairman Bernard Arnault made his first-ever social media post on Monday, using X to share a three-page letter responding to a recent Le Monde investigation that examined his business empire and reported tensions surrounding succession plans within his family. The move marked a rare public statement from France’s richest person, who has traditionally kept a low profile in the media.

Le Monde published a six-part series over six consecutive days exploring Arnault’s luxury goods empire, his business strategy, political influence, media ownership, philanthropy in the arts, tax issues and, in its final installment released Friday, an alleged succession rivalry involving his five children. On Sunday, LVMH published Arnault’s response letter, in which he challenged many of the newspaper’s conclusions while adopting a sarcastic tone.

In the letter, Arnault mocked Le Monde’s description of his family as “the last royal family of France” and joked about the newspaper dedicating six months of reporting and six double-page spreads to covering him. He disputed claims regarding his political influence, business operations and family relationships, arguing that practices criticized in the report are common among major French companies. Arnault also accused the newspaper of presenting other wealthy French families, including the Wertheimers, owners of Chanel, in a more favorable light. He rejected the suggestion that a battle over his succession was “the poison at the heart of LVMH.”

Le Monde has not publicly responded to Arnault’s letter and has left the investigative series online without edits or corrections. Arnault concluded his response by writing, “As for me, rest assured: I will continue doing Le Monde’s crossword puzzles, which are excellent,” according to a Google translation from the original French.

Attention is now turning to whether Arnault will continue using social media. His only post on X so far came Monday, when he reshared LVMH’s publication of his letter and said he was “deeply touched” by the public response.

The family connections surrounding the story extend beyond LVMH. Billionaire Xavier Niel, the principal shareholder of Le Monde, has been in a relationship with Arnault’s daughter, Delphine Arnault, since 2010. Although the couple is not married, they have remained together for more than a decade.

Arnault, 77, oversees LVMH, whose portfolio includes Louis Vuitton, Dior, Moët & Chandon, Dom Pérignon, Sephora, Tiffany & Co. and dozens of other luxury brands. With an estimated fortune of $142.4 billion, he remains France’s wealthiest individual. His five children—Delphine, Antoine, Alexandre, Frédéric and Jean Arnault—all hold senior leadership roles within the company. Xavier Niel, founder of telecom company Iliad, is worth an estimated $15.8 billion and ranks as France’s seventh-richest person.

According to Le Monde’s report, Arnault has spent years preparing all five children to eventually lead the company, while allegedly fostering competition among them rather than promoting unity. The newspaper claimed that children from different marriages had formed alliances as part of a broader succession rivalry and suggested some LVMH shareholders have become concerned about the absence of a clearly defined succession plan. Arnault rejected those assertions in his response.

LVMH is also navigating a challenging business environment following the end of the post-pandemic luxury spending boom. The company reported full-year 2025 revenue of €80.8 billion, approximately $91.8 billion, representing a 5% reported decline and a 1% organic decrease from the previous year. Its fashion and leather goods division has been particularly affected, with weaker demand in China, historically one of the company’s strongest markets. LVMH noted that competitors such as Richemont and Burberry experienced stronger momentum in the region. The company has also cited softer tourism spending and the impact of the Iran conflict on luxury shopping destinations such as Dubai, saying those factors reduced first-quarter 2026 organic growth by about 1%. First-quarter revenue totaled €19.1 billion, or roughly $21.7 billion, down 6% from the same period in 2025, while LVMH shares have fallen around 30% this year.
