Sportsbook Odds Optimization and Correlated Proposition Bet Analysis A Platform for Building and Pricing Player-Prop Parlays

This patent describes a sportsbook back-end that calculates the correlation between proposition bets and sets accurate combined odds for parlays that conventional sportsbooks cannot price reliably, including same-game player-prop parlays.

The Problem

A parlay (or accumulator) combines multiple wagers into a single ticket that pays out only if every leg wins. Pricing a parlay correctly is straightforward when each leg is statistically independent: the combined probability is just the product of the component probabilities. The trouble starts when the legs are correlated. A bet on Quarterback A throwing for over 300 yards is not independent of a bet on Receiver B catching at least one touchdown pass. Old-school sportsbook stacks were not designed to compute these correlations on the fly, so most operators historically refused to accept parlays involving correlated player props, or accepted only a hand-curated list of pre-approved combinations. That conservatism leaves bettors frustrated and leaves the house’s revenue capped at the bets it dares to offer.

What This Invention Does

The platform takes a candidate parlay specified by the bettor, identifies which legs are correlated and to what degree, and recalculates the combined odds with the correlations baked in. Rather than rejecting correlated parlays outright, the system can accept them at odds that reflect the true joint probability and an appropriate house margin. Inputs include historical performance data, real-time game state, and configurable correlation models. Outputs are odds that can be shown to the bettor and submitted into the wager flow within the latency budget of a live sportsbook.

The disclosed method also addresses the operational side: it fits into existing sportsbook infrastructure as an analysis layer that augments, rather than replaces, the bet-acceptance pipeline.

Key Features

• On-the-fly correlation analysis. Computes pairwise and higher-order correlation between proposition bets that share players, teams, or games.
• Joint-probability odds engine. Re-prices parlays so the combined odds reflect dependence between legs rather than treating every leg as independent.
• Configurable house-margin policy. Operators can dial in the margin they want over the modelled true probability, on a per-market or per-event basis.
• Expanded acceptable-bet space. Allows sportsbooks to take bets they would previously have refused, including same-game player-prop parlays, without exposing the book to mispriced risk.
• Designed for live integration. Built to plug into a sportsbook’s existing odds and bet-acceptance infrastructure as a real-time analysis service.

Who Is Behind It?

The applicant is SidePrize LLC, a US sports-betting technology company. The named inventors are David Adam Wexler, Jay Deuskar and Dylan Cooper. The Australian application is a divisional of AU 2019454265, and the family entered the national phase from PCT/US2019/039228 (published as WO 2020/263242). The Australian patent agent is Adams Pluck in Hornsby.

Why It Matters

Same-game parlays and player-prop parlays have become some of the fastest-growing product categories in regulated US sports betting since 2018, and they are similarly important in Australia. The operational difficulty of pricing them accurately has been a persistent constraint on what books can offer their customers and how aggressively they can market new bet types. A platform that brings rigorous correlation modelling into the live odds pipeline expands the menu of acceptable bets and lets operators capture wagering volume that conventional architectures have to leave on the table. The Australian filing positions SidePrize’s IP in a growing legal-betting market.
