The Wertheimer Family — $90 Billion (Chanel)

The Wertheimer family has owned Chanel since Pierre Wertheimer partnered with Coco Chanel in 1924. His grandsons Alain and Gérard now control 100% of the fashion house — which generated $19.4 billion in revenue in 2023. Chanel is the largest privately owned luxury brand on Earth. The Wertheimers are the most secretive family in luxury — they have never given an interview, never appeared on a red carpet, and are rarely photographed. Their combined wealth is estimated at $90 billion. They own the most valuable fashion brand in history and nobody can pick them out of a lineup.
