The 2026 Singapore’s 50 Richest list result reports US$2.1 billion in combined net worth for Christina Ong and her husband, Ong Beng Seng, as of September 2, 2026. That is a couple-level estimate, not a disclosed estimate of Christina Ong’s individual wealth.
What is Christina Ong’s net worth?
No substantiated standalone net-worth figure for Christina Ong is established by the available source. The relevant 2026 list result gives a joint estimate of US$2.1 billion for Ong and Ong Beng Seng, dated September 2, 2026. The result is presented as a Forbes list profile, but it is hosted on a non-Forbes domain, so it should be treated as a reported estimate rather than a verified personal balance sheet. See the 2026 Singapore’s 50 Richest result.
The distinction matters: the combined figure cannot be divided between the two people without evidence, and it does not show how much wealth belongs to Christina Ong alone.
What businesses are associated with Christina Ong?
Company and biographical profiles help explain her business context, but they do not provide a current, asset-by-asset valuation of her personal wealth.
#1 Best Overall
COMO Group
COMO Foundation describes COMO Group as a collection of companies created by founder-owner Christina Ong, with interests spanning hospitality, fashion, wellness, organic living and specialty foods. The group says it is headquartered in Singapore and operates across several countries and lifestyle sectors. Those descriptions establish her association with the businesses; they do not disclose her personal ownership stakes or their value. COMO Foundation’s group description and COMO’s careers page.
In a COMO interview, Ong described the idea behind opening The Halkin in London in 1991: “It started with a feeling that luxury had to mean more than a show of wealth, that’s it’s more intimate than that.” The remark gives context to her hospitality work, not a measure of its financial value.

Club21 and Mulberry
Club21’s official history says Ong founded the Singapore-based luxury fashion curator in 1972 and took control of British luxury leather-goods company Mulberry in 2003. These milestones show the breadth and history of her business activity, but they do not establish the value of her holdings today. Club21’s history.
Biographical context
The Singapore Women’s Hall of Fame profile also discusses Ong’s Club21 founding and her hospitality and wellness businesses. It is useful for biography, but it is not a current independent valuation of her assets. Read the profile.

A business’s existence, sector, or history is not enough to calculate an owner’s net worth. A defensible personal estimate would require evidence about ownership shares, liabilities and asset values; the company descriptions cited here do not provide that breakdown. No substantiated standalone figure for Christina Ong is established by the cited list result or business profiles.
