Abstract: Systems and methods provide an on-line sports wagers and intermediary marketplace for exchanging physical tickets related to future sporting events. Registration at a website and maintenance of user information allow the start of on-line transactions utilizing the system. A user interface for selecting and displaying a minimum price and a maximum price for a physical ticket and a communication network for communicating among user terminals, servers, data repositories, and other computers over the Internet control the on-line system to provide a proxy for escrow accounts used in funding the transactions after legitimacy of a ticket has been verified and to complete the on-line transactions when a successful purchase of the ticket has been communicated. In one aspect, a system can deposit a net value, if any, of a ticket to a proper escrow account after outcome of the future sporting event represented by the ticket has been determined.
