Definition
What is a centimillionaire?
A centimillionaire is generally someone with at least US$100 million in wealth. Sources measure that wealth in different ways, so it matters which count you are reading.
People worldwide with US$100M+ in liquid investable assets in 2024, according to Henley & Partners. Private business stakes are left out.1
People worldwide worth US$100M+ on a net worth basis in 2024, according to Knight Frank. Private holdings are included.2
Neither count is wrong. They measure different things. See all the figures.
