Kalshi
These markets track the performance of quarterbacks Sam Darnold and Brock Purdy in an upcoming football game between San Francisco and Seattle. The outcomes depend on whether each player achieves specific passing completion thresholds during the match. Settlements consider pre-game player availability and in-game participation.
All markets resolve based on the number of passing completions achieved by either Sam Darnold or Brock Purdy in the specified San Francisco vs Seattle Professional Football game. For any market, if the referenced 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 — even if that play is nullified by a penalty — the market resolves according to the actual passing completions recorded during the game. All markets are independent, and each has its own threshold for resolution (e.g., 15+, 20+, etc.). 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, often differing from initial sportsbook lines which are set by oddsmakers. Sportsbooks may incorporate biases or focus on public perception, while this market aggregates the views of many informed traders. As more information becomes available – such as injury reports or weather forecasts – you may see the odds on Kalshi converge or diverge from sportsbook odds. It’s common to observe differences, particularly before significant events influence public opinion.
On Kalshi, this market is priced through a continuous order book where traders buy and sell contracts representing different outcomes. The price of a contract reflects the probability of that outcome occurring, as perceived by the market participants. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders set the odds by placing bids and asks, and the market price fluctuates based on supply and demand. The more a particular outcome is traded, the more liquid it becomes, and the tighter the spread between the bid and ask prices.
This market resolves around Oct 11, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final number of passing completions in the game will be sourced from official league statistics and used to determine which contracts pay out. Traders holding contracts corresponding to the actual number of passing completions will receive a payout, while those holding contracts on incorrect outcomes will not. The resolution process is designed to be transparent and based on objective data.
Several factors could significantly influence this market. Injury reports for key quarterbacks or wide receivers would be major catalysts, as they directly impact a team’s passing ability. Unexpected changes in weather conditions – such as heavy rain or strong winds – could also shift the odds, favoring running plays over passing. Game-day news, like a change in offensive strategy or a surprise starting lineup, could also cause substantial movement in the market. Any information that alters perceptions of the likely passing volume will impact trading activity.
