What happens in the first inning?

Generally, prediction market odds often reflect the wisdom of the crowd, potentially offering a different perspective than traditional sportsbook odds.

Discrepancies can arise due to differing information, biases, or simply the dynamics of each market. It’s common to see prediction markets move more efficiently as new information becomes available, potentially leading to odds that diverge from initial sportsbook offerings.
