These markets track the performance of quarterbacks Sam Darnold and Brock Purdy in a specific football game between San Francisco and Seattle. The outcomes depend on how many passing interceptions each quarterback throws during the match. Markets resolve based on the actual number of interceptions recorded by each player.
The markets evaluate whether designated quarterbacks, Sam Darnold or Brock Purdy, record a specified minimum number of passing interceptions (1+, 2+, or 3+) in the San Francisco vs Seattle Pro Football game scheduled for Oct 11, 2026. If a quarterback is active for the game but does not take a snap, the market settles at the fair market price determined before the game starts. Once a quarterback takes at least one snap—regardless of whether the play is nullified by a penalty—the market resolves based on the actual number of passing interceptions recorded during the game. All markets are independent and resolve separately according to the specific interception thresholds defined for each quarterback. Kalshi explicitly disclaims any affiliation with the governing league, and all trademarks remain the property of their respective owners.
Typically, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks set lines based on their own analysis and aim to balance action on both sides, while this market allows anyone to express their belief about the likelihood of an event. It’s common to see prediction markets move faster to incorporate new information and potentially offer more accurate probabilities than sportsbook lines, though discrepancies can exist due to differing market participants and risk assessments. The current market indicates a different level of confidence than typical polls suggest.
On Kalshi, this market is priced using a continuous double auction, meaning traders buy and sell contracts representing different outcomes. The price of a contract reflects the market's assessment of the probability of that outcome occurring. As more traders participate and new information becomes available, the prices adjust dynamically. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market depth shows the available buy and sell orders at various price points, providing insight into the potential for price movement and the level of conviction among traders.
This market resolves around Oct 11, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the resolution will be based on whether a passing interception occurred during the San Francisco versus Seattle game. The official game statistics will be used to determine the final result. Traders will be able to see the resolution details on Kalshi once the information is officially available and verified, allowing for the final settlement of all outstanding contracts.
Several factors could influence this market before resolution. Any news regarding the quarterbacks’ health or playing status for either San Francisco or Seattle would likely cause significant movement. Changes in weather conditions, particularly if they are expected to be adverse for passing, could also shift the odds. Unexpected reports about defensive strategies or key player matchups could also impact trading activity. Finally, any major shifts in public perception or expert analysis regarding the teams’ offensive capabilities could influence the price of contracts in this market.
