These markets track the performance of quarterback Brock Purdy in an upcoming football game between San Francisco and Atlanta. They focus on whether Purdy will achieve specific passing yard thresholds during the match. The outcomes depend entirely on his in-game statistics.
All markets evaluate Brock Purdy's passing yard performance in the San Francisco vs Atlanta Pro Football game scheduled for October 25, 2026, with varying threshold requirements from 175 to 375 yards. Each market resolves to 'Yes' if Purdy meets or exceeds its specified yardage total during the game. A consistent secondary rule applies across all markets: if Purdy is listed as active for the game but does not take any snaps, the market settles at the fair market price determined before kickoff. However, once Purdy takes at least one snap—regardless of whether the play is later nullified by penalty—the market resolves based strictly on the total passing yards he records during the game. These provisions ensure markets resolve fairly even in edge cases such as injury after initial play or unusual game circumstances, while emphasizing actual performance once Purdy participates in any offensive drive.
Generally, prediction market odds tend to reflect the wisdom of the crowd, often proving more accurate than traditional sportsbook odds, especially in the lead-up to an event. While sportsbooks may initially set lines based on expert analysis and public perception, this market allows a broader range of participants to weigh in. Discrepancies can arise due to differing information access, biases, or simply the dynamic nature of trading activity. It’s common to see the odds on Kalshi adjust rapidly as new information becomes available and traders refine their forecasts.
On Kalshi, this market is priced through a continuous double auction, meaning traders buy and sell contracts representing different outcomes for the total passing yards. The price of each contract reflects the market’s collective belief about the probability of that outcome occurring. As more traders participate, the prices converge to reflect the most accurate prediction. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market depth, or the number of contracts available at each price point, also provides insight into the level of conviction behind different predictions.
This market resolves around Oct 25, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final passing yardage total from the San Francisco versus Atlanta game, as officially recorded by the NFL, will determine the winning contracts. The resolution will reflect the combined passing yards achieved by both teams during the game. Traders holding contracts corresponding to the actual passing yardage range will receive a payout, while those holding losing contracts will forfeit their stake.
Several factors could significantly impact this market. Any news regarding key player injuries – particularly quarterbacks or wide receivers for either team – would likely cause substantial shifts in the odds. Changes in weather forecasts, such as the prediction of heavy rain or strong winds, could also influence the expected passing yardage. Late-breaking reports on team strategies or defensive matchups could also move the market. Finally, significant betting activity itself can create momentum and drive price changes as traders react to each other's actions.
