Description

This market determines which NFL team remains undefeated the longest during the 2026-27 regular season. The outcome depends on the weekly progression of each team's performance, with special rules for ties and bye weeks.

Kalshi

The market resolves based on the team that stays undefeated the longest during the 2026-27 NFL regular season, measured by the week of their first loss. Ties do not count as losses, so a team with ties but no losses remains considered undefeated. If multiple teams lose in the same week, they are tied for the market's purposes. Teams on a bye week are treated as undefeated for that week; if another undefeated team loses during that same week, the bye-week team wins regardless of subsequent weeks. If multiple teams finish the season undefeated, they are tied. In the event of a tie, 'Yes' positions pay $1 divided by the number of tied teams (rounded down), and 'No' positions pay one minus that payout.

Frequently asked questions

On Kalshi, the dashboard for the last undefeated NFL team market tracks real-time odds, price history, and 24-hour volume of $270,744.

This view lets you see market momentum and liquidity without leaving the platform.

On Kalshi, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Kalshi, traders set the price through continuous bidding and asking, with the top outcome’s chance displayed as a percentage.

Volume of $2,513,526 shows how much trading activity is behind each price point, and the market updates instantly after every NFL game that affects contender viability.

This market resolves around Jan 11, 2027, with the outcome confirmed once the event is verifiable from credible public reporting. The final result depends on which NFL team, if any, completes a perfect season — winning every regular-season and playoff game — or if all teams suffer at least one defeat.

On Kalshi, several signals could shift this market before Jan 11, 2027. Major matchups involving currently undefeated teams will be pivotal, with any loss instantly removing a contender and dramatically adjusting probabilities. Injuries to key players, changes in coaching strategy, or unexpected upsets in closely watched games can also create rapid movements. Additionally, broader NFL narrative shifts—such as changing perceptions of team strength based on performance trends—will continue to influence trader behavior and reshape the odds leading up to the final weeks of the season.
