Typically, prediction market odds reflect the wisdom of the crowd, and can differ from traditional sportsbook odds. Sportsbooks often set initial lines to balance action, while this market's prices are driven purely by supply and demand among traders. If a significant number of people believe a particular outcome is more likely than sportsbooks suggest, the price will move accordingly. It’s common to see discrepancies, especially before a large amount of information becomes public or as new developments emerge surrounding the match. These differences can present arbitrage opportunities for informed traders.

As more shares are bought for a particular outcome, its price increases, reflecting a higher implied probability. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of a share represents the probability of that outcome occurring, and traders aim to profit by correctly predicting the result. The market dynamically adjusts to new information and changing sentiment, creating a constantly updated forecast.
