Who will win Arizona Diamondbacks vs Los Angeles Dodgers?

Prediction market odds and sportsbook odds often diverge because they reflect different incentive structures. Sportsbooks set lines to balance action and lock in profit margins, while prediction markets are driven purely by trader consensus on true probability. This market's odds represent what thousands of independent traders believe will happen, free from the vig or juice that sportsbooks charge. Over time, prediction markets have proven competitive with or more accurate than traditional oddsmakers, especially when traders have strong information or analytical edge on the matchup.

On Polymarket, traders set prices by buying and selling outcome shares in an automated market maker system. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each share represents a claim on one outcome—either an Arizona victory or a Los Angeles victory—and the price of each reflects the collective belief in that outcome's likelihood. As more traders buy shares for a particular team, that team's price rises and the competing outcome's price falls. The market remains open to new trades until the event concludes, allowing prices to adjust continuously based on fresh information and shifting expectations.

The outcome is determined by which team wins the matchup under official Major League Baseball rules and scoring. No ambiguity typically surrounds the winner in a completed game, making resolution straightforward. Traders holding shares in the winning outcome receive their payout, while those on the losing side forfeit their stake. The exact timing of payout processing depends on Polymarket's confirmation procedures following the final result.
