For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution.

Pisa SC will face SSC Napoli in a Serie A fixture on 17 May 2026, with the match scheduled for 09:00 ET. The current order book on Polymarket reflects a 10% implied probability for the YES outcome on this "More Markets" contract, suggesting traders view the specified condition as unlikely given the teams' respective form and standing at that stage of the season.
Napoli have historically dominated fixtures against lower-placed Serie A sides, particularly in May when league positions are settled. Pisa, promoted to Serie A in recent seasons, typically finish in mid-table or lower positions. Historical matchups between established top-flight regulars and newly promoted or struggling clubs show YES probabilities in this range when the favourite is heavily favoured. The 10% mark reflects conventional expectations for an underdog outcome, though late-season volatility and squad rotation can shift these dynamics.
Traders should monitor team news in the weeks preceding the fixture, including injury reports and any European competition involvement that might affect squad availability for either side. Napoli's position in the final standings and any managerial changes will influence their approach. Pisa's form trajectory through April and early May will be material, as will any mid-season transfers or tactical shifts. The settlement window closes at 13:00 UTC on 17 May, allowing traders to react to pre-match information and team sheets released on match day morning.
This market settles from the official outcome published at https://www.legaseriea.it/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
The mechanics for trading "Pisa SC vs. SSC Napoli - More Markets" are the same as any other PolyGram sporting event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$0 in lifetime turnover and $25K of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is modest — expect a couple of cents of slippage on $1k+ trades.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is sourced from https://www.legaseriea.it/. Settlement is executed by the UMA optimistic oracle on Polygon, with a 2-hour dispute window before payouts clear.
This prediction market is scheduled to close on 17 May 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
