4. Gustav Magnar Witzoe
Age: 26
Net Worth: $3 Billion
The fourth youngest billionaire in the world is Gustav Magnar Witzoe.
At just 26 years old, he’s worth $3 billion, thanks to the 50% stake in Salmar ASA given to him by his father and company founder, Gustav Witzoe.
Salmar pioneered the industrialization of fish farming in Norway, enabling the company to make much higher margins and therefore, more profits.
Gustav Magnar Witzoe is the fourth-youngest billionaire in the world and lives in Keverva, Norway.
