Often, prediction market odds reflect a different set of information and incentives than those found at traditional sportsbooks.

As a result, you may see discrepancies between the two. It’s common to find that prediction markets are more efficient at incorporating new information quickly, potentially offering a more accurate assessment of the true probability of an event happening.
