sextupling

Sextupling means multiplying by six or increasing sixfold.

As a verb form, it describes the process of making something six times as large or numerous: The company's revenue is sextupling this quarter.

As a noun or adjective, it characterizes such an increase: The sextupling of housing prices has made the area unaffordable.

The word follows the pattern of doubling, tripling, and quadrupling but sees far less use outside technical or statistical contexts.
