This event tracks the combined run total scored by both Boston and Chicago White Sox in their professional baseball game scheduled for July 9, 2026. Bettors predict whether the teams will collectively exceed various run thresholds throughout the game.
Resolution is based on the final combined run total scored by Boston and Chicago White Sox in the game originally scheduled for July 9, 2026 at 2:10 PM EDT. Each outcome corresponds to a specific run threshold; the market resolves Yes if the combined total exceeds that threshold. For example, the Over 3.5 runs outcome resolves Yes if the teams score more than 3.5 runs combined, the Over 4.5 runs outcome resolves Yes if they score more than 4.5 runs combined, and so forth through Over 13.5 runs. The official final score as recorded by Major League Baseball determines resolution.
Prediction market odds and sportsbook odds often diverge because they serve different purposes and audiences. Sportsbooks set lines to balance action and manage risk, while prediction markets like this one aggregate the beliefs of many independent traders competing for profit. This market reflects real-time consensus from participants who have skin in the game, which can sometimes offer a more efficient price than traditional sportsbooks. Comparing the two can reveal where sharp traders see value relative to conventional betting lines.
On Kalshi, this market is priced through an order-book mechanism where traders submit bids and asks for shares representing different run-total outcomes. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each outcome reflects the balance of buy and sell orders at any moment, meaning the implied probability adjusts continuously as new trades execute. Prices converge toward the true likelihood as more information arrives and traders compete to exploit mispricings, creating a dynamic and transparent pricing process.
This market resolves around Jul 9, 2026, once the World Series concludes and the final run total is confirmed. The outcome is determined by the combined runs scored by both teams across all games played in the series. Resolution is verified against credible public sources reporting the official final statistics. Once the series ends and the total is established, the market settles and traders receive payouts based on which outcome they held.
Key injuries to star players on either roster could significantly shift expectations for offensive output. Changes in weather forecasts for game venues may affect scoring conditions. Momentum swings during the series itself—such as dominant pitching performances or offensive explosions—will drive repricing as traders update their run-total estimates. Lineup adjustments, bullpen availability, and head-to-head matchup dynamics all influence how many runs each team is likely to score. Real-time game results will be the strongest catalyst, as each completed game narrows the possible final total and reshapes the odds.
