Abstract: A host system defines an event having a pool. The event is contingent on an outcome. The host system receives event data such as a stake value, a certainty value, and content data from network entities coupled to the network. The host system may identify and exclude network entities from the event and accordingly release their bids. The host system computes an estimated allotment for each active network entity and communicates the estimated allotments to the network entities. The estimated allotment may be based on a multiplier, determined based on certainty values of the event data. The host system determines outcome data and an actual allotment for the active network entities based on the outcome data. The host system generates and communicates results data to be displayed. The host system generates a command to allot respective winnings to the appropriate network entities, by transferring winnings to a beneficiary account.

Abstract: A method and system for improving liquidity of transactions for a plurality of contracts is disclosed. The method and system include defining a complete set including the plurality of contracts. The complete set guarantees at least an initial settlement value at at least one particular time. The complete set also corresponds to a settlement value that is determined based upon the initial settlement value. Preferably, the settlement value is determined based upon the initial settlement value and an interest rate effect.

Abstract: A method and system for improving liquidity of transactions for a plurality of contracts is disclosed. In one aspect, the method and system include providing a special purpose vehicle for buying and/or selling at least a portion of a complete set including the plurality of contracts. The complete set guarantees at least an initial settlement at at least one particular time. The complete set also corresponds to a settlement value. The settlement value is determined based upon the initial settlement value. In another aspect, the method and system include defining a complete set including the plurality of contracts and allowing at least one market participant to lock in a trade for a portion of the plurality of contracts. The portion of the plurality of contracts includes multiple contracts. The complete set guarantees at least an initial settlement at at least one particular time. The complete set corresponds to a settlement value. The settlement value is determined based upon the initial settlement value.

Abstract: A method and system for managing risk for contracts offered for trading in systems is disclosed. A complete set of contracts includes the contracts, each of which matures upon event(s) occurring. The complete set guarantees at least an initial settlement value at at least one particular time. The complete set also corresponds to a settlement value, which is based upon the initial settlement value and an, preferably, interest rate effect, if any. A winning contract pays a notional upon maturing. Rate differential(s) between systems, and hedging costs exist. In one aspect, the method and system include determining whether a matching trade in a second system for a trade in a first system is possible, determining whether conducting the trades is profitable and, if so, performing these trades. In another aspect, the method and system determine whether individually selling the contract(s) is profitable given the rate differential.

Abstract: A method and system for improving liquidity of transactions for a first plurality of contracts for a pari-mutuel (PM) pool or auction is disclosed. In one aspect, the method and system include providing a complete set including a second plurality of contracts. The complete set guarantees at least an initial settlement value at at least one particular time. The complete set also corresponds to a settlement value, which is determined based upon the initial settlement value. In another aspect, the method and system include obtaining a plurality of orders corresponding to a plurality of contracts. In this aspect the method and system include performing a price auction on the plurality of orders and then performing a quantity auction to determine a quantity of the plurality of orders which are qualified.
