Leong On Kei has an estimated net worth of $2 billion, according to Forbes Real-Time Billionaires, Leong On Kei profile (figures as of October 20, 2026). That is down from a peak of $4.1 billion.
Leong On Kei is a Hong Kong businesswoman and Macau legislator with major interests in casinos and property. She is co-chairman and the largest individual shareholder of SJM Holdings, the casino company tied to Stanley Ho’s business group. SJM runs casino resorts in Macau, including L'Arc and the Grand Lisboa Palace Resort. She also served as a directly elected legislator after entering politics in 2005, building a public role alongside her business career.
Her wealth came from 2 main areas named in public reporting: casino holdings and a large Hong Kong property portfolio. Forbes says most of her fortune comes from real estate, and notes that she started investing in her early 20s. Before that, she trained and worked as a dance teacher. In 1986, she met Stanley Ho through his brother, who attended her dance class. Over time, she moved deeper into casino management and broader investment work.
Where her wealth comes from
A big part of Leong On Kei’s profile comes from SJM Holdings. She is its co-chairman and biggest individual shareholder. The company is listed in Hong Kong and operates casino resorts in Macau, including L'Arc and the Grand Lisboa Palace Resort. She is also a director of Sociedade de Jogos de Macau from its founding and became managing director in December 2010, giving her a long operating role in the casino business.
Forbes also points to property as the bigger engine behind her fortune. It says she holds a large portfolio of Hong Kong properties and that this accounts for the vast majority of her wealth. That fits with her long investment track record, which began in her early 20s. In September 2017, she also bought Aldwych House in London for about £250 million, showing that her real estate reach extends beyond Hong Kong and Macau.
How Forbes' estimate moved
Forbes has shown a lower estimate for Leong On Kei over time. It put her fortune at $4.1 billion on the 2019 World's Billionaires List. By 2024, that figure was $2.4 billion. The latest reading is $2 billion on Forbes' real-time billionaires tracker as of October 20, 2026. Public notes connect her money mainly to casinos and, even more, to her Hong Kong property holdings, so changes in those assets can affect the estimate.
Her money story is not only about one company. SJM Holdings gives her a visible casino stake, but Forbes says most of her wealth is tied to property. That matters because her public image often centers on Macau gaming, while the bigger financial base sits in real estate. She also has a political role in Macau and founded the Macau Sanshui Communal Association, adding civic influence to a career built around investment, casino management, and property ownership.
