About trillionaire
A trillionaire is a person whose net worth is at least one trillion units of a given currency, typically the US dollar due to its status as a world currency. A trillionaire is the highest tier of ultra-high-net-worth individuals. In June 2026, Elon Musk became the only US dollar trillionaire in history upon the initial public offering of his company, SpaceX, but Musk's net worth has been under $1 trillion since early July 2026, after a SpaceX stock collapse wiped hundreds of billions from his net worth.
