This set of markets focuses on determining the margin of victory for the San Francisco 49ers versus the Miami Dolphins in the fourth quarter of their scheduled football game. Each market specifies a different point differential threshold that must be exceeded for the outcome to be considered a success.
These markets evaluate whether the San Francisco 49ers or Miami Dolphins win the fourth quarter of their scheduled game by exceeding specific point differentials. All markets exclusively consider points scored during the fourth quarter of regulation time, with overtime points excluded from calculation. Each market has a distinct threshold: outcomes range from narrow victories (e.g., winning by more than 2.5 points) to decisive margins (e.g., winning by more than 10.5 points). The resolution depends solely on the point difference between the two teams at the end of the fourth quarter, without regard to the overall game result or any subsequent overtime periods. All markets operate independently, meaning each resolves based on its own specified threshold regardless of other market outcomes.
Typically, prediction market odds reflect the wisdom of the crowd and can sometimes differ from traditional sportsbook odds. Sportsbooks set lines based on their own models and need to account for a profit margin, while this market is driven purely by traders expressing their beliefs about the likely outcome. If a significant discrepancy emerges between this market and sportsbook lines, it may indicate that the crowd believes the sportsbook is mispricing the probability of a particular result. However, it’s important to remember that both represent probabilities, and neither is guaranteed to be correct.
On Kalshi, this market is priced through a continuous order book where traders can buy and sell contracts representing different point spreads for the 4th quarter. The price of each contract reflects the market’s assessment of the probability of that spread occurring. 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 emerges, the prices adjust to reflect the collective intelligence of the market. Essentially, the price tells you how much it costs to take one side of the bet – for example, to bet that the 49ers will win the 4th quarter by more than a certain number of points.
This market resolves around Sep 20, 2026, with the outcome confirmed once the final result of the 4th quarter of the MIA Dolphins vs. SF 49ers game is verifiable from credible public reporting. The resolution will be based on the official point spread at the end of the 4th quarter, as determined by official game statistics. The final score difference will determine which contracts pay out and at what value, based on the spread represented by each contract. Traders holding winning contracts will receive a payout of 100 per contract.
Several factors could influence the price of this market. Any news regarding injuries to key players on either the Dolphins or the 49ers would likely cause significant movement. Changes in weather forecasts, particularly if they suggest conditions favorable to one team’s style of play, could also impact trading activity. In-game performance during the first three quarters, even if not directly affecting the 4th quarter spread, could shift sentiment and influence traders’ expectations. Finally, any large volume trades on Kalshi could also cause noticeable price fluctuations.
