Sofie Kirk Kristiansen Net Worth

Sofie Kirk Kristiansen has an estimated net worth of $7.9 billion, according to Forbes Real-Time Billionaires, Sofie Kirk Kristiansen profile (figures as of October 20, 2026). That is up from $4.7 billion in 2019.

Sofie Kirk Kristiansen is a Danish fourth-generation owner of the Lego Group. She and her father, sister, and brother split ownership of a 75% stake in the company. Her family connection to Lego goes back to founder Ole Kirk Christiansen. He began making wooden toys in 1932 and moved into plastic in the 1940s. Kristiansen is not involved in the business, while her brother Thomas serves as Lego's deputy chairman.

Her wealth comes from the family's large holding in Lego and another major family investment. The family also owns a 47.5% stake in Merlin Entertainments, the theme park operator that it took private with a consortium. Kristiansen studied ethnography at Aarhus University and is part of one of Denmark's best-known business families. Forbes put her net worth at $7.9 billion on its real-time billionaires tracker as of October 20, 2026.

How Sofie Kirk Kristiansen built her wealth

Kristiansen's fortune is tied to ownership, not an operating role. She is a fourth-generation owner of Lego, and she shares a 75% family stake with her father, sister, and brother. That ownership position is the main source of her wealth. Although she is not involved in running the company, the family's long-held stake connects her wealth to the toy maker's business and brand.

The family's money is not only linked to Lego. Forbes notes that the family also has a 47.5% stake in Merlin Entertainments. The company operates theme parks, and the family took it private with a consortium. That gives Kristiansen exposure to another large consumer business alongside Lego. Her background in the family traces back to Ole Kirk Christiansen, who started with wooden toys in 1932 before moving into plastic in the 1940s.

How Forbes' estimate changed

Forbes' estimates for Kristiansen moved sharply over time. It placed her fortune at $4.7 billion in 2019, then $6.1 billion in 2020 and $8.7 billion in 2021. After that, the estimate was $8.2 billion in 2022, $6.7 billion in 2023, and $6.5 billion in 2024. Those changes reflect how Forbes valued her share of the family's assets across different years.

The estimate then turned higher again. Forbes put her at $7.2 billion in 2025 and $8.3 billion on the 2026 World's Billionaires List. On October 20, 2026, Forbes' real-time tracker showed $7.9 billion. Her wealth remains closely tied to the family's stakes in Lego and Merlin Entertainments, so changes in those holdings' estimated value can affect the total from year to year.
