Newly riches is a term often used to describe individuals who have recently acquired wealth or become financially successful.

Nouveau riche is a French term that literally means new rich and is commonly used to describe individuals who have recently acquired a significant amount of wealth but lack the social status and cultural refinement that is typically associated with old money. Parvenu is another term that is similar in meaning and is used to describe individuals who have risen to a higher social class but lack the pedigree or background of those born into that class. Upstart and arriviste are also used to describe individuals who have suddenly become rich or successful, but often carry negative connotations implying that they are not deserving of their newfound wealth.
