PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. 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. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

Manchester City and Brentford meet on 9 May 2026 in a Premier League fixture. The corners market is currently priced at 100% implied probability on Polymarket's order book, indicating certainty that the total corners threshold will be exceeded. This extreme pricing typically reflects either very shallow liquidity in the order book or a settlement threshold set substantially below historical norms for these fixtures.
Corner frequency in Premier League matches between top-six sides and mid-table opponents has historically ranged from 8 to 14 corners per match. Manchester City's possession-dominant style under their manager typically generates 5–7 corners per game, whilst Brentford's direct approach and defensive set-piece focus produces 4–6. Combined, these teams average around 10–11 corners when they meet, suggesting the threshold is likely set at a level well below typical outcomes. The 100% probability reflects this structural imbalance rather than exceptional confidence in the underlying event.
Traders should monitor team news closer to the fixture date, particularly injury status for key players that might affect pressing intensity or set-piece delivery. Brentford's recent form and whether they field a full-strength squad will influence their corner generation. Weather conditions on match day—wind and rain increase corner frequency—warrant attention in early May. The settlement window closes at 16:30 GMT on 9 May, shortly after the 17:30 GMT kick-off, so live trading opportunities will be limited once the match begins.
This market settles from the official outcome published at https://www.premierleague.com/. 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 "Manchester City FC vs. Brentford FC - 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.
$8K 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.

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.
