Sportsbooks set their odds based on their own models and risk management, while this market allows anyone to express their belief about the outcome. If prediction market odds diverge significantly from sportsbook odds, it could suggest that the market believes the sportsbook is mispricing the probability of a particular outcome. It’s important to remember that both represent probabilities, but are derived through different mechanisms.
