Technologies are described herein for providing a marketplace for the remaining term of reserved instances. A selling customer identifies a reserved instance of a computing resource for which the customer wishes to sell a remainder of their term and specifies an asking price. A reserved instance listing associated with the identified reserved instance and asking price is created. A buying customer provides a specification of reserved instances that they wish to purchase, including a term. The specification may also include size, platform, tenancy, availability zone, and other parameters of the reserved instances. The reserved instance listings are searched to find associated reserved instances matching the specification and having a remaining term equal to or greater than the term in the specification. The reserved instances associated with the reserved instance listings having the lowest asking price may then be transferred from the selling customer to the buying customer.
