Typically, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks often set initial lines to balance betting action and incorporate a profit margin, while this market allows traders to directly express their beliefs about the outcome. If a significant difference exists, arbitrage opportunities may emerge, where traders can profit by betting on both platforms. However, it’s important to remember that prediction markets and sportsbooks have different user bases and information sources, leading to varying perspectives.
On Polymarket, this market is priced through a continuous auction mechanism, where traders buy and sell shares representing their belief in the probability of a particular outcome. The price of these shares fluctuates based on supply and demand. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders buy shares indicating a belief that Thea Frodin will win, the price of those shares increases, and vice versa.
