Snapshot observed 2026-10-19T03:00:06.086Z. This analysis describes that snapshot and is not a live news update.

What the contract measures

The supplied Kalshi event asks whether specific players will reach a set RBI threshold in a Cleveland vs Tampa Bay game "originally scheduled for Oct 19, 2026 at 8:08 PM EDT" [1]. Each contract is a separate yes or no question. The 1+ RBI contracts resolve Yes if the player records at least one RBI, and the 2+ contracts require at least two.

The rules add conditions that matter for comparison. If a player is scratched, is not in the starting lineup, or starts without a plate appearance, the market "will resolve to the fair market price" [1]. Pinch hit at bats do not count [1]. The source also says the market "will close and expire after the event occurs" [1]. That is different from the listed end time in the market data, which is 2026-10-22T00:08:00Z for every contract. The source does not state an event end time, so the listed timestamp should not be read as a confirmed event or settlement date.

Reading the snapshot

The prices were observed at 2026-10-19T03:00:06Z and retrieved at 2026-10-19T03:34:54Z [1]. They describe that moment only and may not match current prices. They are not executable quotes or verified probabilities.

All 12 saved markets come from one Kalshi event and are marked as a complete sample [1]. Within the 1+ RBI set, Junior Caminero's Yes price is 0.32, Jo Adell's is 0.285, Yandy Díaz's and José Ramírez's are each 0.245, Jonathan Aranda's is 0.23, and Brayan Rocchio's is 0.185. Within the 2+ set, Caminero is at 0.135, Adell at 0.11, Aranda and Ramírez at 0.09 each, Díaz at 0.085, and Rocchio at 0.055.

Because the 1+ and 2+ contracts ask different questions, a player's 1+ price and 2+ price should not be treated as competing estimates. The volume field is not supplied, so these snapshots say nothing about liquidity or how many traders participated.

What remains uncertain

The evidence does not explain why any price is where it is, and it contains no news, lineup information, or trader counts. The sample warning states that the saved markets do not establish that every possible outcome is listed [1]. Only one platform is included, so no cross-platform comparison is possible. A price difference between contracts with different wording, thresholds, or close times is not, by itself, an arbitrage opportunity.
