Market context
Napoli travel to Udinese on 24 May for a Serie A fixture scheduled at 9:00 AM ET, with settlement occurring at 13:00 UTC that same day. The 0% YES probability currently reflected on Polymarket suggests traders are pricing this conditional token at minimal value, indicating either extreme confidence in a specific outcome or minimal liquidity depth in this particular market cluster. On-chain settlement will depend on official Serie A records; USDC collateral sits on Polygon whilst conditional tokens resolve according to the match result or specified market parameters.
Napoli finished the 2024–25 season in mid-table, whilst Udinese has historically occupied a similar competitive band. When examining comparable late-season Serie A fixtures between mid-ranking sides, markets typically show wider probability distributions than the current 0% reading suggests, particularly when settlement windows remain open. The absence of meaningful YES probability here warrants scrutiny of the exact market condition—whether it specifies a narrow outcome (such as a precise scoreline or player performance metric) rather than a simple win/loss binary.
Traders should monitor official Serie A fixture confirmations and any squad announcements in the week preceding 24 May. Injury updates to key players, managerial changes, or fixture postponements would directly affect settlement eligibility. The early kick-off time (9:00 AM ET) compresses the window between market close and settlement, leaving minimal time for late-breaking news to influence pricing. Check Polymarket's conditional token specifications carefully, as the 0% reading may reflect a market structure where the YES condition is genuinely unlikely rather than mispriced.

Methodology
This page reviews SSC Napoli vs. Udinese Calcio - More Markets across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at PolyGram — the application we operate, where you trade directly against the Polymarket order book at 0% fees.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
