Sportsbooks often incorporate a 'vig' or commission into their odds, while prediction markets, like Polymarket, aim to reflect the true probability as assessed by traders. If a significant difference exists between the implied probability on this market and sportsbook odds, it could indicate disagreement about the likely outcome or differing levels of information available to each group. It's important to consider both when forming an opinion.
