Frequently asked questions

Prediction market odds often reflect the wisdom of the crowd, potentially differing from those set by sportsbooks. Sportsbooks establish initial lines based on statistical models and expert analysis, while this market aggregates the beliefs of many individual traders. If a significant number of traders believe a sportsbook’s line is inaccurate, they can influence the odds on Polymarket through their trading activity. This dynamic can lead to prediction market odds providing a different perspective on the likely outcome of the Marlins-Diamondbacks game than traditional betting venues.

On Polymarket, this market is priced through a continuous auction mechanism where traders buy and sell shares representing their belief in the outcome. The price of a share directly corresponds to the probability of that outcome occurring, as perceived by the market participants. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The more traders who buy shares in a particular outcome, the higher its price will climb, indicating increased confidence.
