Abstract: Methods and systems for determining optimal ticket pricing using an estimated future interest in a live event. The methods and systems may include processors configured to determine relationships that are indicative of interest in a live event using one or more types of data, including live event data that indicates characteristics of individual live events, ticket data that indicates information regarding ticket sales to past live events, user data that indicates characteristics, past purchases, and/or affinities of individual users. The processors may also generate and maintain a live event interest model that is configured to use one or more determined relationships to estimate interest in an upcoming live event. The processors may use one or more types of data, the determined relationships, or the live event interest model to estimate future interest in an upcoming live event.
