A "glitzy figure in Singapore and abroad",Ong is married to Christina (née Fu), the daughter of an oil magnate. They have two children, a daughter and a son. Ong was described by Hilary Clarke of The Independent as "media shy" and "notoriously secretive". Despite that, he is known to be well-acquainted with many Hollywood celebrities.

Ong's business approach is to "buy when rents and properties are cheap and sell when they are not." As of July 2012, the Ong family, comprising Ong and his wife, is worth $1.6 billion, based on estimates by Forbes, making the couple Singapore's 10th richest persons.
