Cagliari Calcio vs. SS Arezzo

Platform comparison

Market context

Cagliari will host Arezzo in a Coppa Italia fixture on Friday evening, with settlement tied to the match's completion by 16:30 UTC on 14 August 2026. The 92% implied probability reflects strong confidence that the game will proceed as scheduled, though the settlement window closes just hours after typical Italian football kick-off times, creating a narrow margin for delays or postponements.

Coppa Italia early-round matches between Serie A and lower-division sides rarely face cancellation once fixture lists are confirmed. Historical precedent suggests that administrative or weather-related postponements occur in fewer than 3% of scheduled matches at this stage of the competition. Cagliari, a Serie A regular, and Arezzo, competing in Serie C, represent a straightforward pairing unlikely to generate scheduling complications that would trigger rescheduling.

The key variable traders should monitor is weather forecasting for Sardinia on 14 August, particularly any alerts issued by the Lega Serie A in the 48 hours preceding kick-off. Fixture confirmations typically arrive 72 hours before match day; any official announcement regarding venue or date changes would move the probability materially. Team news around injuries or squad availability rarely affects whether a Coppa Italia match occurs, though it may influence competitive intensity. The settlement window's tight closure means any fixture delay beyond the scheduled time could create ambiguity, making real-time weather and official league communications the primary drivers of movement from current levels.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
