Prediction market odds often reflect the wisdom of the crowd, potentially differing from traditional sportsbook odds due to varying information and incentives. Sportsbooks set lines based on their own models and need to account for profit margins, while this market allows anyone to trade on their beliefs. If a significant discrepancy exists, arbitrage opportunities may arise, where traders can profit by betting on both venues. It's common to see prediction markets move faster to incorporate new information than sportsbooks, especially in response to breaking news or shifts in public opinion.
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 corresponds to 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. As more people trade, the price fluctuates, reflecting the collective assessment of the event's likelihood. This dynamic pricing allows for a constantly updated probability assessment of who will win the Shanghai doubles match.
