Description

This set of markets focuses on predicting the margin of victory for either Kansas City or Seattle specifically in the second half of their football game, including any overtime periods. Each market corresponds to a different point differential threshold that must be exceeded for the outcome to be considered valid.

Kalshi

These markets resolve based on the point differential by which either Kansas City or Seattle wins during the second half of their Pro Football game scheduled for October 25, 2026, including any overtime periods. Each market specifies a different threshold that must be exceeded for a 'Yes' resolution. For markets where Seattle is the favorite to win by a certain margin, the condition is met if Seattle's second-half points exceed Kansas City's by more than the specified amount. Conversely, for markets where Kansas City is the favorite, the condition is satisfied if Kansas City's second-half points surpass Seattle's by more than the stated margin. Crucially, only points scored during the second half—including any overtime periods—are considered when calculating the winning margin for these markets. All markets operate independently, meaning each threshold must be evaluated separately against the actual game result.

Typically, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks often set initial lines to balance action, incorporating a profit margin, while this market represents the collective prediction of informed traders. If a significant discrepancy exists between this market and sportsbook lines, it may suggest that the crowd believes the sportsbook has mispriced the probability of a particular outcome. It’s important to note that both represent probabilities, but are derived through different mechanisms.

On Kalshi, this market is priced through a continuous order book where traders buy and sell contracts representing their beliefs about the second-half spread. The price of a contract reflects the probability of that spread occurring. As more traders participate, the price converges towards what the market believes is the true probability. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Price movements are driven by new information, analysis, and shifts in sentiment among traders, creating a dynamic and real-time assessment of the game's potential outcome.

This market resolves around Oct 26, 2026, with the outcome confirmed once the official second-half point spread of the Kansas City versus Seattle game is verifiable from credible public reporting. The final spread will be determined by the official game statistics, and the contracts will pay out based on whether the actual spread falls above or below the purchased contract’s value. Traders will be able to view the final result and settlement details on Kalshi following the completion of the game.

Several factors could influence the price of this market before the game concludes. Any news regarding key player injuries to either Kansas City or Seattle would likely cause significant movement. Changes in weather forecasts, particularly if they are expected to impact the passing or running game, could also shift predictions. Furthermore, late-breaking analysis from sports analysts or unexpected betting trends in traditional sportsbooks could influence trader behavior and, consequently, the price of contracts in this market.
