Prediction market odds often reflect the collective wisdom of a diverse group of traders, and can sometimes differ from those offered by traditional sportsbooks. Sportsbooks set their odds based on their own models and risk assessments, while this market is driven by the willingness of individuals to buy or sell shares. If a significant number of traders believe a player has a higher chance of winning than sportsbooks suggest, the odds on Polymarket will likely shift accordingly. It's common to see discrepancies, especially before a lot of money has been traded on this market.
On Polymarket, this market is priced through a continuous auction mechanism where traders buy and sell shares representing their belief in the probability of each player winning. The price of a share directly corresponds to the implied probability of that outcome. As more traders participate, the price adjusts to reflect the collective assessment of the event's likelihood. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now.
