Singapore, one of the most expensive cities in the world, is home to an estimated 44 billionaires.

These ultra-wealthy individuals range from real-estate magnates and private investors to hot pot billionaires and even the cofounder of Facebook.

The richest person in Singapore is Li Xiting, the founder and CEO of a company that supplies medical devices. Li didn’t even break into the top 15 richest people in Singapore in January – now, he’s worth $18.1 billion, according to Forbes’ Real-Time Billionaires list. The executive’s wealth has skyrocketed during the coronavirus pandemic as countries around the world buy his company’s medical products, which include ventilators, imaging devices, and patient monitors, per the South China Morning Post.

In March 2019, Li was worth $5.5 billion, per Forbes. By April 2020, his fortune had swelled to $11.6 billion.

Earlier this year, Singapore's richest person was Zhang Yong, a 50-year-old restaurateur who chairs the popular Sichuan hot pot chain Haidilao, which has locations in China, the US, Japan, South Korea, and Singapore. Now, Zhang has been knocked down to the second spot by Li. Zhang's wife, Shu Ping, the director of the company, is also on Singapore's billionaires list, with a net worth of $3.4 billion.

Here are Singapore's richest people, who are worth a combined $111.7 billion.
