Kalshi
This event tracks the performance of both teams in a football game, focusing on how many times each team's defense can tackle the opposing team's quarterback behind the line of scrimmage. The outcome depends on whether specific thresholds of these tackles, known as sacks, are met by either team during the match.
The event resolves based on the total number of sacks recorded by each team during the Philadelphia vs Chicago Pro Football game scheduled for September 28, 2026. Sacks are counted only during standard play; those occurring during 2-point conversion attempts are excluded. If the game is postponed but starts within 48 hours of the original time, betting remains open and resolves according to the final official result. If the game does not start within 48 hours of its scheduled time, all markets resolve to a fair price, ensuring equitable treatment for all participants. Each market has a specific threshold for sacks—ranging from 2 to 6 sacks for each team—and resolves to 'Yes' if the respective team meets or exceeds its threshold. The markets are independent, allowing for multiple outcomes depending on the performance of both teams' defenses.
Typically, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks often set initial lines based on power rankings and expert analysis, while this market allows anyone to trade on their beliefs. If a significant number of traders believe a particular outcome is more likely than sportsbooks suggest, the odds on Kalshi will shift accordingly. Discrepancies can arise due to differing information, biases, or simply a broader range of participants influencing the price. It’s common to see prediction markets outperform traditional odds in accuracy.
On Kalshi, this market is priced through a continuous order book where traders buy and sell contracts representing different outcomes for the total number of sacks in the game. The price of each contract reflects the market's collective belief about the probability of that outcome occurring. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Traders are constantly adjusting their bids and asks based on new information and their own analysis, leading to dynamic price movements. The more traders believe an outcome will happen, the higher the contract price will rise, and vice versa. This creates a real-time assessment of expectations.
This market resolves around Sep 29, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final number of sacks recorded in the Philadelphia versus Chicago game will be used to determine the winning contracts. The official NFL game statistics will serve as the source of truth for the resolution. It’s important to note that any sacks that occur during overtime will be included in the final count. Traders should monitor official game results to understand the resolution process for this market.
Several factors could influence the price of this market. Injury reports for key offensive linemen or defensive players on either team would be significant catalysts. Any news regarding the weather conditions – particularly if a storm is predicted – could also shift expectations, as inclement weather often impacts passing offenses and sack opportunities. Unexpected changes in coaching strategies or player matchups could also move the market. Finally, any late-breaking news regarding player availability or team performance will likely be reflected in the trading activity on Kalshi.
