Abstract: This invention allows users to register interests in pre-determinable possible outcomes for a fixed-time event. The system comprises a plurality of remote networked user devices, which include respective displays and input devices such as keypads or keyboards for receiving user inputs in response to information displayed on the display. These devices are connected through a communications network via peer-to-peer and/or via one or more server-based connections. More specifically, the system allows an offering user to offer an interest in a first pre-determinable possible outcome for the fixed time event at a given interest multiplier. It also allows an acquiring user to request an interest in the first pre-determinable possible outcome at the given multiplier. The system then matches the offer and the request to define a commitment by the acquiring user to acquire the requested interest at the given multiplier.
