Typically, prediction market odds reflect the wisdom of the crowd, often differing from initial sportsbook offerings. Sportsbooks set lines to balance action and incorporate a profit margin, while this market allows traders to express their own probabilities. If a significant number of traders believe a sportsbook has mispriced an outcome, the odds on Polymarket will adjust accordingly. Discrepancies can arise due to differing information, analytical approaches, or simply varying levels of confidence in a particular player's chances. It's common to see prediction markets move closer to the 'true' probability as more information becomes available.
On Polymarket, this market is priced through a continuous auction mechanism, where traders buy and sell shares representing their belief in each outcome.

On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market’s price is determined solely by supply and demand within Polymarket, and is not influenced by external factors or other prediction venues.
