What happens in the first inning?

Generally, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks set lines based on their own models and aim to balance action on both sides, while this market allows traders to express their own beliefs about the probability of a first inning run. Discrepancies can arise due to differing information, biases, or simply the dynamic nature of each market. It’s common to see prediction markets move more quickly to incorporate new information than sportsbooks, potentially offering a more accurate assessment of the event’s probability.
