Kalshi
This market tracks the outcome of the upcoming Major League Baseball game between the Pittsburgh Pirates and the Chicago White Sox. Currently, the consensus probability favors a Pittsburgh Pirates victory at 99.0%. This aggregate reflects data from Predict and Kalshi, with resolution determined by official final statistics from the event organizers as detailed in the resolution source. Given the conflicting resolution dates across platforms – specifically the game scheduled for September 10th versus September 10, 2026 on Kalshi – focus on the predict market’s resolution based on the September 10 at 7:40PM ET game time.
The market resolves based on the winner of the Pittsburgh vs Chicago WS professional baseball game originally scheduled for September 10, 2026, at 7:40 PM EDT. If the game is postponed or delayed but played within two days of the original date, the market remains open and closes after the rescheduled game concludes. If the game is cancelled or rescheduled to more than two days beyond the original date, the market resolves to a fair price. Kalshi is not affiliated with the Governing League, and all trademarks, logos, and brand names belong to their respective owners.
In the upcoming MLB game between the Pittsburgh Pirates and Chicago White Sox, scheduled for September 10 at 7:40PM ET: This market will resolve to "Pittsburgh Pirates" if the Pittsburgh Pirates win the game. This market will resolve to "Chicago White Sox" if the Chicago White Sox win the game. If the game is postponed, this market will remain open until the game has been completed. If the game is canceled entirely, with no make-up game, or ends in a tie, this market will resolve 50-50. The primary resolution source for this market is the official final statistics of the event as recognized by the governing body or event organizers. However, if the governing body or event organizers have not published final match statistics within 24 hours after the event's conclusion, a consensus of credible reporting may be used instead.
Differences in prices between Kalshi and Predict can arise from several factors. Kalshi and Predict can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Each platform has a different user base with varying levels of expertise and access to information, which can influence their predictions. Trading mechanisms also differ; Kalshi operates with a different order book and fee structure compared to Predict. Furthermore, the volume traded on each platform – currently $3,476,332 in 24-hour volume – impacts price discovery and can create temporary imbalances. These factors contribute to the observed price discrepancies in this market.
