This market focuses on determining which team will score the most points in the second half of an upcoming football game between the Detroit Lions and the Arizona Cardinals. It specifically evaluates performance from the start of the third quarter through the end of regulation time, including any overtime periods.
If Arizona wins the 2nd Half (including overtime) of the DET Lions vs ARI Cardinals Pro Football game originally scheduled for Oct 11, 2026, then the market resolves to Yes. If Detroit wins the 2nd Half (including overtime) of the DET Lions vs ARI Cardinals Pro Football game originally scheduled for Oct 11, 2026, then the market resolves to Yes. If neither team wins the 2nd Half (including overtime) of the DET Lions vs ARI Cardinals Pro Football game originally scheduled for Oct 11, 2026, then the market resolves to Yes.
Prediction market odds often reflect the wisdom of the crowd, potentially differing from those initially set by sportsbooks. Sportsbooks establish lines based on their own models and aim to balance action on both sides, while this market allows anyone to express their belief about the outcome. If a significant number of bettors believe a sportsbook’s line is inaccurate, the price on Kalshi will move accordingly. This can result in prediction market odds being more accurate, especially as the event approaches and more information becomes available. It’s a fascinating comparison of different forecasting methods.
On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing each possible outcome – in this case, the Lions winning the second half, the Cardinals winning the second half, or neither team winning. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The price of each contract reflects the market’s collective probability assessment of that outcome. As more traders participate and new information emerges, the prices adjust, providing a dynamic representation of expectations. The goal is to converge on a price that accurately reflects the true likelihood of each scenario.
This market resolves around Oct 11, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The winning team of the second half, or a determination that neither team won, will be the basis for settlement. The official result will be determined by the game’s final score and verified against reliable sports news sources. Traders holding contracts for the correct outcome will receive a payout, while those holding contracts for incorrect outcomes will not.
Several factors could influence the price of this market. Any news regarding injuries to key players on either the Lions or the Cardinals would likely cause significant movement. Changes in weather conditions, particularly if they favor one team’s playing style, could also impact trading activity. Furthermore, in-game performance during the first half, such as a dominant showing by one team, could lead traders to adjust their expectations and shift prices on Kalshi. Unexpected coaching decisions or strategic adjustments could also play a role.
