Parma and Roma will meet in Serie A on 10 May 2026, with this market tracking the total number of corner kicks awarded during the match. The current 0% implied probability on Polymarket's order book suggests traders are pricing an extremely low likelihood of the specified corner threshold being exceeded, though the exact threshold figure would determine whether this reflects genuine scarcity of corners or simply illiquidity at the current price level.
Historical corner data from Serie A encounters between these clubs and comparable fixtures shows significant variance. Roma typically generates 4–6 corners per match across domestic competition, whilst Parma's corner production has ranged between 3–5 per fixture depending on tactical setup and opposition. The 0% probability reading likely reflects either minimal order book depth at present or a threshold set sufficiently high that traders view it as improbable given typical Serie A corner distributions, which average 8–10 per match across both teams combined.
Key variables for traders monitoring this market include team selection announcements closer to the fixture date, which influence pressing intensity and attacking width. Managerial changes at either club between now and May 2026 could alter corner-generation patterns substantially. Weather conditions on match day—particularly wind strength—occasionally affect corner frequency. The settlement window closes at 16:00 GMT on 10 May, providing a fixed endpoint once the fixture concludes. Current illiquidity on the order book means early position-building may face significant slippage.
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 "Parma Calcio 1913 vs. AS Roma - Total Corners" 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.
$2K in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $468 in turnover, well above the lifetime daily-average for this market — a clear sign of news catalysing trader activity right now.
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.

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.
