Intro

This market on Kalshi tracks whether all hitters combined will record at least 6 inside-the-park home runs throughout the 2026 Pro Baseball season, including both regular season and playoff games. An inside-the-park home run occurs when a batter circles all bases on a single hit without the ball leaving the field—an exceptionally rare occurrence in professional baseball. The leading outcome currently stands at 98.0% probability on Kalshi. Resolution is determined by official statistics from the 2026 Pro Baseball season. Watch for the completion of the 2026 playoff season by December 1, 2026, when the final count of inside-the-park home runs will be tallied for resolution.

Kalshi

Inside-the-park home runs recorded by all hitters combined across all games during the 2026 Pro Baseball season (regular season and playoffs) will determine resolution. Markets resolve to Yes based on whether the total reaches or exceeds specific thresholds: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11 inside-the-park home runs.

Frequently asked questions

Comparing prediction market odds to sportsbook odds reveals how the wisdom of the crowd differs from traditional oddsmaking. Sportsbooks often set initial lines based on statistical models and expert analysis, while this market allows anyone to trade on their beliefs. If a significant discrepancy exists, it may indicate that traders believe the sportsbook is mispricing the probability of this event occurring. It's common to see prediction markets, like this one, incorporate information and perspectives not fully captured by conventional betting lines, potentially leading to more accurate predictions over time.

On Kalshi, this market is priced using a continuous double auction, meaning traders buy and sell contracts representing different outcomes. The price of a contract reflects the market’s collective probability of that outcome occurring. As more traders participate, the prices adjust to reflect the latest information and sentiment. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market price essentially represents the expected cost to own a contract that pays out if the event occurs, and traders aim to profit by buying low and selling high, or vice versa. This dynamic pricing mechanism ensures the market efficiently incorporates new information.

This market resolves around Dec 1, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the final count of inside-the-park home runs hit during the 2025 Major League Baseball regular season will be used to determine whether the total exceeds 15. Official MLB statistics will serve as the basis for this verification. Traders will be able to see the final result and any payouts associated with their contracts following the conclusion of the baseball season and the official release of the statistics.

Several factors could influence the trading activity in this market. Early-season trends in stolen bases and aggressive base running by teams could signal a higher likelihood of inside-the-park home runs. Injuries to key outfielders known for their range could also shift expectations. Major rule changes affecting gameplay, such as alterations to base sizes or outfield dimensions, would be significant catalysts. Any news regarding player strategies or coaching philosophies related to aggressive base running could also move this market, as traders adjust their assessments of the probability of 15+ inside-the-park home runs.
