This event group covers the halftime result of the AS Roma vs. US Lecce Serie A match scheduled for March 22, 2026. Markets track whether Roma wins, Lecce wins, or the teams draw at the end of the first 45 minutes plus stoppage time.
Kalshi's single market lists three mutually exclusive outcomes (Roma win, Lecce win, Tie) all resolving to Yes, creating a logical contradiction. Polymarket correctly structures three separate binary markets with exclusive Yes/No logic.
Hero Tip:
Kalshi's market definition is logically incoherent for a binary market. Polymarket's three-market approach (Roma leading, Draw, Lecce leading) is the only resolvable framework. Request clarification from Kalshi or treat their market as unresolvable until corrected.
Critical Divergence Points:
Kalshi:
Single market with three outcomes all resolving Yes: Roma win, Lecce win, or Tie each trigger Yes resolution. This violates binary market logic and makes the market unresolvable.
Polymarket:
Three separate binary markets: (1) Roma leading at halftime (Yes if Roma ahead, No otherwise), (2) Draw at halftime (Yes if tied, No otherwise), (3) Lecce leading at halftime (Yes if Lecce ahead, No otherwise). Includes explicit postponement (market remains open) and cancellation (resolves No) rules.
