Katarina Martinson Net Worth

Katarina Martinson has an estimated net worth of $2.8 billion, according to Forbes Real-Time Billionaires, Katarina Martinson profile (figures as of October 20, 2026). That is up from $1.1 billion in 2019.

Katarina Martinson is a Swedish businesswoman and investor and one of the heirs to the Lundberg family fortune. She was born in 1981, the daughter of Fredrik Lundberg, the longtime head of the family holding company L E Lundbergföretagen. Her sister is Louise Lindh.

She has a master's degree from the Stockholm School of Economics. Martinson is married and lives in Stockholm, where in 2017 she reportedly paid roughly $15 million for a townhouse in the city center, one of the most expensive homes ever sold in Sweden.

Besides her family roles, she is an active private investor and owns stakes in the clothing company NN07 and the online cosmetics retailer Lyko. She chairs the industrial group Indutrade, which made her the youngest chairman of a company on the Stockholm Stock Exchange. Her mix of family duties and personal investments reflects a new generation taking a hands-on role in one of Sweden's oldest business dynasties.

How Katarina Martinson got her money

The family business was founded by her paternal grandfather, Lars Erik Lundberg, in 1944 as a construction company. Her father took over management of the firm in 1981 and turned it into an investment group. Today L E Lundbergföretagen holds property management businesses and a range of other investments, including a pulp and paper company.

Martinson and her sister each own about 15% of the holding company, according to Forbes. Both sisters sit on boards of the group's companies alongside their father, and Martinson is a director of L E Lundbergföretagen itself. Her role as chair of Indutrade, one of the companies the group invests in, makes her one of the most visible younger figures in Swedish business. The holding company's stakes in listed Swedish firms mean the sisters' wealth is tied closely to how those companies perform on the stock market.
