Description

These markets track how decisively either team wins the first half of an upcoming football game. Each market corresponds to a different point margin threshold, allowing participants to speculate on the relative performance of the teams within the first half alone.

Kalshi

All markets resolve based solely on the point differential in the first half of the specified game. If the San Francisco 49ers win the first half by exceeding the specified margin—for example, more than 20.5, 17.5, 14.5, etc.—the corresponding 'Yes' outcome is triggered. Conversely, if the Arizona Cardinals win the first half by exceeding their respective margins—such as more than 2.5, 3.5, 4.5 points up to 10.5—the associated market resolves to 'Yes'. Only points scored during the first half are considered; any points from the second half are irrelevant for resolution. All markets are independent, meaning each threshold is evaluated separately, and the outcome of one does not affect the others.

This market resolves around Sep 28, 2026, with the outcome confirmed once the event is verifiable from credible public reporting.

Several factors could influence the price of this market before resolution. Any news regarding injuries to key players on either the Cardinals or the 49ers would likely cause significant movement. Changes in weather conditions, particularly if they are expected to affect the passing or running game, could also shift the market. Finally, any late-breaking news related to team strategy or coaching decisions could impact predictions and alter the price of contracts for the Cardinals-49ers first half spread.
