Kjeld Kirk Kristiansen has an estimated net worth of $7 billion, according to Forbes Real-Time Billionaires, Kjeld Kirk Kristiansen profile (figures as of October 20, 2026). That is up from $4.7 billion in 2019.
Kjeld Kirk Kristiansen is a Danish businessman best known as a third-generation owner of Lego. He led the toy company from 1979 to 2004 as president and chief executive officer. During his time running the business, Lego expanded with themes, minifigures, LEGO.com, Lego Mindstorms, and licensed properties. After leaving the top executive job, he remained tied to the company through family ownership and leadership roles connected to the wider Lego group.
His wealth is tied to Lego, the toy maker built around interlocking plastic bricks. The business started in 1932, when his grandfather Ole began making wooden toys in a workshop, then moved into plastic in the 1940s. Kristiansen and his children evenly split ownership of a 75% stake in the company. The family also owns about half of Merlin Entertainments, the theme park operator that was taken private with a consortium in 2019.
How his Lego fortune works
Most of Kristiansen's fortune comes from the family's large ownership stake in Lego. He ran the company from 1979 to 2004, a period when Lego added major product ideas and digital steps such as LEGO.com. Forbes places him in Manufacturing, and the company is a big business with $7.2 billion in sales. Because he and his children evenly split a 75% stake, his wealth is closely linked to Lego's value and performance.
His money is not tied only to toy sales. The family also owns about half of Merlin Entertainments, which runs theme parks and was taken private in 2019 with a consortium. Lego's brand also extends into attractions. The original Legoland in Billund, built in 1968, is made up of over 20 million Lego bricks. Kristiansen stepped down from Lego's board in 2019, but the family's ownership remained the core of his fortune.
What Forbes says about his wealth
Forbes estimated Kristiansen's net worth at $7 billion on its real-time billionaires tracker as of October 20, 2026. That figure is tied mainly to the family's Lego stake and also to other holdings such as Merlin Entertainments. Since his fortune comes from ownership rather than a salary role, the estimate depends on what those assets are worth at a given time. His later career has been shaped more by ownership than day-to-day management.
The family connection behind that wealth goes back many decades. His grandfather Ole started the business in 1932 by making wooden toys before moving into plastic in the 1940s. Kristiansen later led Lego from 1979 to 2004, helping guide key additions such as themes, minifigures, LEGO.com, Lego Mindstorms, and licensed properties. He left Lego's board in 2019, while the family's holding company leadership was set to pass to his son Thomas in 2023.
