Generally, prediction markets like Polymarket often reflect information and insights different from those priced into traditional sportsbook odds. Sportsbooks set lines to balance action and incorporate a profit margin, while this market aggregates the wisdom of the crowd. If a significant discrepancy exists between the two, it might indicate differing opinions on the likely outcome or that the market has identified information not yet fully reflected in sportsbook lines. It's important to note that prediction market odds can be more dynamic and responsive to new information than sportsbook odds.
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 reflects the probability of that outcome occurring. As more traders buy shares in a particular outcome, its price increases, and the implied probability rises. 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 among traders on Polymarket, and is not influenced by external factors or a central authority setting the price.
