Trillionaire
Person who has at least one trillion units of a currency
From Wikipedia, the free encyclopedia
A trillionaire is a person whose net worth is at least one trillion (one thousand billion) units of a given currency, typically US dollars. It is a subcategory of the concept of ultra-high-net-worth individuals. Elon Musk is the first and only person to have a verified net worth exceeding US$1 trillion with the initial public offering of his company SpaceX on 12 June 2026.[1][2][3][4]

There have been trillionaires in other currencies, generally due to hyperinflation, such as the Hungarian pengő in 1946 and the Zimbabwean dollar in 2008.[5][6] The word "trillionaire" first appeared in The New York Times in 1927, in reference to hyperinflation in the Weimar Republic.[7]
