# Pro Football Last Undefeated Team — 2026-27

Live · $1,548,930 traded · listed on Kalshi, Polymarket

## About

Note: This market resolves based on the team that stays undefeated the longest, measured by the week of their first loss (not exact date/time). A tie (game result) does not count as a loss. Therefore, a team with a tie on its record is still considered undefeated if they have not lost yet.
Same-Week Losses: If the last remaining undefeated teams lose in the same week of the season, they are considered tied for the purposes of this market, even if one lost on Thursday and the other Sunday of that week.
Bye Weeks: A team on a bye-week is treated as still undefeated that week; if the other last undefeated team loses that same week, the team on a bye wins, regardless of what happens the following week.
Multiple Teams Go Undefeated: If multiple teams finish the 2026-27 Pro Football regular season undefeated, then they are considered tied for the purposes of this market.
Tie Resolution: If multiple teams are tied for the last undefeated team, “Yes” positions will pay $1/N (rounded down to the nearest cent), where N is the number of tied teams, and “No” positions will pay 1 minus the "Yes" payout.
