According to the Forbes 2013 list of billionaires, 3 percent are eligible bachelors. Here are the top five, all under 50.
1. Alejandro Santo Domingo Davila
Net worth: $11.7 billion
Santo Domingo Davila has amassed one of the world’s largest beer fortunes from Bavaria Brewery, and he owns the private Caribbean island of Baru. The competition for his affections, though, is steep: He’s been sighted with heiress Amanda Hearst and Sports Illustrated model Julie Henderson in recent years.
2. Xavier Niel
Net Worth: $6.6 billion
Niel once went to jail on pimping charges, but those were later cleared. He’s now the largest individual stakeholder of Iliad, a French telecommunications company, and he owns Frank Sinatra’s hit "My Way."
3. Scott Duncan
Net Worth: $5.1 billion
Duncan inherited $2 billion, when his father died in 2010, from a stake in the Houston-based pipeline company, Enterprise Products Partners. He’s apparently not married, but stays under the radar.
4. Tor Peterson
Net Worth: $2.3 billion
Peterson runs Glencore International’s coal and coke department from Switzerland and hails from California. He graduated from Duke University in 1986.
5. Eduardo Saverin
Net Worth: $2.2 billion
Saverin made his fortune from a 5 percent stake in Facebook, half of which he has already sold. He renounced his American citizenship in 2011 for tax purposes. He now lives in Singapore and frequents Filter, reportedly Singapore’s most exclusive nightclub.
