Sportsbooks set lines based on their own models and risk management, while this market aggregates the opinions of many individuals. It’s common to see discrepancies, especially before significant events or when new information emerges. Comparing the two can reveal where public sentiment diverges from professional analysis, potentially highlighting undervalued or overvalued outcomes.

The price of a share directly reflects 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 believe a particular outcome will happen, the higher the price of its corresponding shares will rise, and vice versa.
