Typically, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks often set initial lines based on statistical models and expert analysis, while this market allows anyone to trade on their beliefs, potentially leading to a more accurate assessment of probabilities. Discrepancies can arise due to differing levels of information, biases, or simply variations in how each source interprets the available data. It's common to see prediction markets react more quickly to new information than sportsbooks.
On Polymarket, this market is priced through a continuous auction mechanism, where traders buy and sell shares representing their belief in the outcome.
