Kalshi
These markets focus on predicting whether specific Cleveland and Detroit baseball players will achieve certain run batted in (RBI) thresholds during their upcoming game. The outcomes depend entirely on the players' performance in terms of driving in runs during scheduled plate appearances.
The official rules establish that each market resolves to 'Yes' only if the specified player records the exact number of RBIs or more in the designated game. All markets share consistent secondary participation criteria: if a player is scratched, not in the starting lineup, or enters the game as a pinch hitter without recording a plate appearance, the market resolves to the fair market price. Crucially, only RBIs from starting lineup appearances and subsequent plate appearances count—pinch-hit at-bats are explicitly excluded. All markets emphasize that Kalshi bears no official affiliation with the governing league, and all trademarks remain property of their respective owners. Settlement hinges strictly on whether the player, when actively participating via starting lineup or mid-game entry with plate appearances, meets or exceeds the RBI threshold defined for each market.
