Dan Olsson Net Worth

Dan Olsson has an estimated net worth of $3.8 billion, according to Forbes Real-Time Billionaires, Dan Olsson profile (figures as of October 20, 2026). That is down from a peak of $4.2 billion.

Dan Olsson is a Swedish businessman who runs Stena Sphere, a privately held conglomerate based in Gothenburg. Born in February 1947, he is the son of Sten Allan Olsson, who started the business in 1939 as a trading company. The family story has a fun twist. In 1946 his father bought his first ship, a three-masted schooner named Dan, and when his first son arrived a year later, he gave him the same name.

Olsson studied at the Gothenburg School of Business, Economics and Law before joining the family enterprise. He took over the company in 1983 and has served as its chief executive ever since. Under his leadership, Stena grew far beyond its roots in trading into a group with interests at sea and on land. He is married and still lives in Gothenburg, where the company is based.

How Dan Olsson makes money

Olsson's wealth comes from his controlling stake in Stena Sphere. He owns 51% of the company, which gives him majority control. The group works across cruising, shipping, offshore drilling, property and metal recycling. That mix means Stena earns money from very different markets, from ferry and cruise travel to energy services, real estate and the recycling of scrap metal.

The rest of the company stays in the family. His brother Stefan Sten Olsson owns 24.5%, and his sister Madeleine Olsson Eriksson owns 12.5%. Madeleine's children, Gustav and Marie, each hold 6% and sit on different boards within the group. Keeping the business private and family-owned means Forbes values Olsson's stake based on the overall worth of Stena's many operations.

How Forbes has valued Dan Olsson

Forbes estimated Olsson at $4 billion in 2019. His figure fell to $2.9 billion in 2020 before rebounding to $3.9 billion in 2021. It then dropped to $2.7 billion in 2022 and held at $2.7 billion in 2023. Shipping and offshore drilling can be cyclical businesses, so changes in those markets help explain why his estimate has moved up and down.

In recent years the trend has turned upward. Forbes put him at $2.8 billion in 2024 and $3.1 billion in 2025. On its 2026 World's Billionaires List, his estimate reached $4.2 billion, the highest in this period. As of October 20, 2026, the Forbes real-time billionaires tracker showed him at $3.8 billion, still well above his low point earlier in the decade.
