Description
This event group covers the professional Serie B soccer match between Mantova 1911 and UC Sampdoria scheduled for February 21, 2026. Markets track three mutually exclusive outcomes: Mantova win, Sampdoria win, or draw, all resolved based on the result after 90 minutes plus stoppage time (regular play only).
PredictionHero - Resolution Divergence Alerts (RDA)
Unified Resolution Criteria (Consistent across platforms)
Both Polymarket and Kalshi align on the core resolution logic: match outcome determined after 90 minutes plus stoppage time, with identical handling of postponements and cancellations.
Primary resolution logic:
Lega Serie B official website (legaserieb.it) and professional Serie B recordsCore resolution logic:
- Match result is determined after 90 minutes of regular play plus stoppage time only
- Extra time and penalty shootouts are excluded from resolution scope
- Three mutually exclusive outcomes: Mantova 1911 win, UC Sampdoria win, or draw
- If match is postponed, all markets remain open until the match is completed
- If match is canceled entirely with no makeup game, draw market resolves Yes and both win markets resolve No (Polymarket) or implicitly fail to resolve Yes (Kalshi)
Edge cases & Clarifications:
- Match Postponement: Markets remain open and unresolved until the rescheduled match is completed; resolution then follows standard outcome rules
- Match Cancellation Without Makeup: Polymarket draw market resolves Yes; Polymarket win markets resolve No. Kalshi structure implies no Yes resolution for any outcome market if match never occurs
- Scope Limitation: Resolution is strictly limited to the result after 90 minutes plus stoppage time; knockout stage extra time or penalties do not apply
Timing:
Resolution occurs immediately after the match concludes on February 21, 2026, or on the rescheduled date if postponedOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms.
