Sportsbooks set their lines based on their own models and risk management, while this market is driven by individuals freely trading on their beliefs. It’s common to see discrepancies between the two, especially early on, as prediction markets can quickly incorporate new information and adjust probabilities. Examining these differences can be valuable for informed decision-making, but remember that both represent probabilities, not guarantees.
