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.

AS Roma will host ACF Fiorentina on 4 May 2026 in a Serie A fixture, with the corners market currently pricing at 0% implied probability on Polymarket's order book. This suggests either an extreme consensus on the outcome or minimal liquidity formation at present, typical for matches scheduled several months ahead. The settlement window closes at 18:45 UTC on match day, allowing traders to adjust positions as kickoff approaches and team news crystallises.
Corners markets in Serie A typically reflect both tactical approach and squad intensity. Roma and Fiorentina have historically favoured possession-based play, though corner frequency varies significantly based on defensive shape and width of attacking play. Recent seasons show Serie A matches averaging 8–11 corners per game, with derby or high-stakes fixtures trending toward higher counts due to increased pressure and direct play. The current 0% probability on Polymarket suggests either the threshold is set at an unusually high level or the market has not yet attracted sufficient order flow to establish meaningful price discovery.
Traders should monitor team news closer to the fixture, particularly injury status of key fullbacks and wing players who generate crossing opportunities. Fixture congestion in late April and early May may influence tactical selections—teams chasing European qualification or fighting relegation typically generate more set-piece situations. Fiorentina's European commitments and Roma's domestic position will shape squad rotation decisions. Weather conditions on match day, particularly wind, can materially affect corner counts and warrant attention in the final week before settlement.
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 "AS Roma vs. ACF Fiorentina - 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.
$13K 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.
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.
