Abstract: A wagering system and method may include a processor that filters bet types available for placement of a bet by a user according to user-input betting criteria, and that presents the filtered bet types that satisfy the criteria in a user interface via which the user may place a bet of one of the presented bet types. The user may input particular criteria to customize the available results of the bet filter as desired. The system may output an identification of a surest bet. The system may provide a slider control for input of a desired payout amount or odds, or range thereof, as criteria according to which the system filters bet types.

Abstract: Methods and systems for replicating derivatives strategies and for trading derivatives strategies in a demand-based trading market are described. In one embodiment, a set of contingent claims are created to replicate a derivatives strategy. One or more parameters of a contingent claim in the replication set may be determined as a function of one or more parameters of a derivatives strategy and an outcome of the event. An investment amount for a contingent claim in the replication set may be determined as a function of one or more parameters of the contingent claim and a total amount invested in a demand-based auction. In other embodiments, derivatives strategies and/or financial products are enabled to be traded in a demand-based auction and are offered to customers and/or traded in the auction.

Abstract: A system and method for event outcome prediction may include a processor configured to receive via a user interface a user-selection of a subset of a plurality of listed statistical categories, and rank participants of the event based selectively on analysis of the statistical information concerning the selected subset of categories. The system may output the ranked list as a predicted outcome, and may further output a user interface via which to place a bet on the predicted outcome.

Abstract: An enhanced parimutuel platform allows for the combination of multiple and single event wagers within a single pool, while maintaining payouts for the single event wagers that are independent of the multiple events. The enhanced parimutuel platform also allows for uniform payouts for wagers having a different number of outcomes for a single event, such as moneyline and point spread wagers.

Abstract: Methods and systems for engaging in enhanced parimutuel wagering and gaming. In one embodiment, different types of bets can be offered and processed in the same betting pool on an underlying event, such as a horse or dog race, a sporting event or a lottery, and the premiums and payouts of these different types of bets can be determined in the same betting pool, by configuring an equivalent combination of fundamental bets for each type of bet, and performing a demand-based valuation of each of the fundamental bets in the equivalent combination. In another embodiment, bettors can place bets in the betting pool with limit odds on the selected outcome of the underlying event. The bets with limit odds are not filled in whole or in part, unless the final odds on the selected outcome of the underlying event are equal to or greater than the limit odds.

Abstract: Methods and systems for trading and replicating contingent claims, such as derivatives strategies, in a demand-based auction are described. In one embodiment, a set of demand-based claims, each of which can be a vanilla option or a digital option, approximate or replicate the contingent claim into a vanilla replicating basis or a digital replicating basis, and the order for the contingent claim is then evaluated or processed in the demand-based auction. In another embodiment, a plurality of strikes and a plurality of replicating claims are established for a demand-based auction on an event, one or more replicating claims striking at each of the strikes in the auction. A contingent claim, such as a derivatives strategy, is replicated with a replication set that includes one or more of the replicating claims in the auction. The equilibrium price and/or the payout for the derivatives strategy is determined as a function of the demand-based valuation of each of the replicating claims in the replication set.

Abstract: Methods and systems for conducting demand-based trading are described. In one embodiment, states are established, each state corresponding to at least one possible outcome of an event of economic significance. An investment amount may be determined as a function of a selected outcome, a desired payout, and a total amount invested in the states. In another embodiment, an investment amount may be determined as a function of parameters of a financial product. In another embodiment, a payout may be determined as a function of an investment amount, a selected outcome, a total amount invested in the states, and an identification of a state corresponding to an observed outcome of the event.

Abstract: Systems, methods, apparatus, and means for improving liquidity in a securities auction include selecting a cover to use to provide general liquidity to the auction, the cover having a plurality of options, calculating a fair value price for each option in the cover, creating an order associated with each of the options, and submitting the orders during the auction.

Abstract: This invention provides methods and systems for trading and investing in groups of demand-based adjustable return (“DBAR”) contingent claims, including digital options, and for establishing markets and exchanges for such claims. The advantages of the present invention, as applied to the establishment and operation of a DBAR digital options exchange, include the ability to offer investments whose profit and loss scenarios are comparable to those for digital options or other derivatives in traditional securities markets, without the need for options or derivatives sellers or order-matching of conventional markets. A DBAR digital options exchange of the present invention can also offer conditional investments, or limit orders, in which an investment in a state of a DBAR contingent claim (such as the price of an underlying asset or index) can be executed or withdrawn in response to the implied probability of the occurrence of that state.
