What happens in the first inning?

Typically, prediction market odds offer a distinct perspective compared to traditional sportsbooks. Sportsbooks often incorporate a 'vig' or commission into their odds, representing their profit margin, while this market aims to reflect the collective wisdom of traders. Discrepancies can arise due to differing information, analytical approaches, or simply variations in public perception. If significant differences exist, arbitrage opportunities may emerge, where traders can profit by simultaneously betting on both platforms. However, it’s important to note that this market’s odds are solely determined by supply and demand on Kalshi.

On Kalshi, this market is priced through a continuous order book where traders buy and sell contracts representing their belief about whether a run will be scored in the first inning.

On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders are incentivized to provide accurate predictions, as profitable trades are rewarded. The current market reflects the aggregated sentiment of all participants trading on Kalshi.
