How Stefan Quandt makes money

Most of Stefan Quandt's fortune comes from BMW. Forbes says he owns 23.6% of the automaker, and he serves as deputy chairman of its supervisory board. The company connection goes back to his family, and his position makes BMW the clear center of his business profile. His sister, Susanne Klatten, also holds a major stake, which keeps the family closely tied to the company at the board level.

His wealth is not limited to auto shares. Forbes says his holdings also include Heel, which makes homeopathic medicine, Entrust, which works in digital identity and data security, and Logwin, a logistics company. He also used Delton AG to manage major holdings from 1989 onward. Earlier in his career, he worked at Boston Consulting and later handled marketing in Hong Kong for Entrust, giving him operating experience before taking larger board roles.

Forbes net worth snapshot

Forbes has tracked big swings in Stefan Quandt's fortune over time. It put his net worth at $17.5 billion in 2019, then $12.3 billion in 2020. The estimate later rose to $21.6 billion in 2021 and $20.7 billion in 2022. Forbes then raised it to $24.6 billion in 2023 and $27.3 billion in 2024. Because BMW is central to his wealth, changes in that stake can have a large effect on the estimate.

The pattern kept moving after that. Forbes estimated $23.8 billion in 2025 and $30.1 billion in 2026 on its World's Billionaires list. As of October 20, 2026, Forbes' real-time billionaires tracker put him at $23.1 billion. Forbes also points to stakes outside BMW, including Heel, Entrust, and Logwin, which help explain why his wealth profile reaches beyond one company even though automotive remains his main industry.
