A collaborative prediction system for altering predictive outcomes of dynamic processes may include a processor configured to store initial information about a specific dynamic process having a plurality of potentially differing outcomes, assign to the specific dynamic process a first likelihood of occurrence of at least one of the potentially differing outcomes, and receive, from a first system user, notification data, the notification data being associated with the specific dynamic process. The processor may be configured to transmit, based on the notification data, at least some of the stored initial information about the specific dynamic process to the second system user and the third system user, receive from the second system user, first additional information responsive to the at least some of the stored initial information about the specific dynamic process and impacting the specific dynamic process, and generate, based on the first additional information and the initial information, a second likelihood different from the first likelihood. The processor may further be configured to transmit to the first system user, the second system user, and the third user an indication of the second likelihood, receive from the third system user, second additional information impacting the specific dynamic process, generate, based at least in part on the second additional information, a third likelihood different from the first likelihood and the second likelihood, and transmit to the first system user, the second system user, and the third system user an indication of the third likelihood.
