Robinhood (Rothera)Rules
If Arizona is the last remaining undefeated team in the 2026-27 Pro Football regular season, then the market resolves to Yes.
- 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.
