A method, system, and computer program product for pricing data according to provenance-based use in a query are provided in the illustrative embodiments. A set of data cubes is identified. A data cube in the set comprises a quantum of data configured for trading in exchange for a payment, the set being identified to participate in answering the query. A first portion of a price for performing the query is computed, which includes a price of a first data cube computed using a first set of provenance attributes and a first provenance-based pricing adjustment from a first pricing definition, the first data cube being included in the set. A confidence level of a result set of the query is computed. The set of data cubes, the first set of provenance attributes, the first portion of the price, and the confidence level are presented in a pricing preview of the query.
