Kalshi
This market asks whether Washington will win the second half of their game against San Francisco by more than 3.5 points. Currently, the probability of Washington winning the 2nd half by over 3.5 points is 60.0% on Kalshi. Resolution will be determined by the outcome of the Washington vs San Francisco Pro Football game originally scheduled for Oct 19, 2026, as defined by whether Washington wins by more than 3.5 points in the 2nd half (including overtime). Keep an eye on the game itself, as the market will resolve based on the final result reported after the conclusion of play on October 20, 2026.
The event consists of multiple markets, each defined by a specific point differential threshold that San Francisco or Washington must exceed in the second half (including overtime) of the game scheduled for October 19, 2026. For markets where San Francisco is the favorite, the outcome resolves to 'Yes' if San Francisco wins the second half by more than the specified margin—ranging from 2.5 to 20.5 points. Conversely, markets where Washington is the favorite resolve to 'Yes' if Washington wins the second half by more than the specified margin—ranging from 2.5 to 10.5 points. In all cases, only points scored during the second half and any overtime periods count toward the final determination. The resolution depends solely on the point differential in the specified timeframe, regardless of the overall game result.
Typically, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks set lines based on their own models and aim to balance action on both sides, while this market allows anyone to trade based on their own information and analysis. Often, you’ll find this market incorporates information more quickly than sportsbooks, especially as new developments arise before the game. However, sportsbook odds are widely available and provide a useful benchmark for comparison, showing how the public perceives the likelihood of different outcomes.
On Kalshi, this market is priced through a continuous order book, where traders buy and sell contracts representing their belief about the second-half spread. The price of these contracts directly reflects the probability of Washington covering the spread against San Francisco. On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate and new information becomes available, the price adjusts to reflect the collective assessment of the market. This dynamic pricing mechanism means the odds are constantly evolving, offering opportunities for traders to capitalize on perceived mispricings.
This market resolves around Oct 20, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the final point spread difference between Washington and San Francisco at the end of the second half will be compared to the market’s spread to determine winning contracts. The resolution will be based on official game statistics and will be publicly available following the conclusion of the game. Traders holding contracts on the correct side of the spread will receive a payout.
Several factors could significantly impact this market. Any news regarding injuries to key players on either Washington or San Francisco would likely cause price movement. Changes in weather forecasts, particularly if they suggest conditions favoring one team’s offensive or defensive style, could also shift the odds. Furthermore, late-breaking reports about team strategies or coaching decisions might influence trader sentiment. Even public perception, as reflected in polls or expert analysis, could contribute to fluctuations in the market price before the game concludes.
