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: A wagering system and method may include a processor that presents indicative odds in a parimutuel wagering system to the user such that the user may place a bet of one of the presented bets, besides for a win bet and an exacta bet.

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.
