Crystal Palace and Everton meet on 10 May 2026 in a Premier League fixture scheduled for 9:00 AM ET. The corners market is currently trading at 100% implied probability on Polymarket's order book, indicating traders expect the total corners threshold to be breached with near-certainty. This extreme probability typically reflects either a very low threshold, substantial historical precedent, or both factors combined.
Corner frequency in Premier League matches has remained relatively stable over recent seasons, with typical fixtures generating 8–12 corners across both teams. Both Palace and Everton have exhibited moderate corner-taking patterns historically, neither ranking among the league's most aggressive pressing sides nor the most defensive. The 100% reading suggests the settlement threshold sits well below typical match averages—likely in the 6–8 range—making the outcome heavily favourable to the YES side. Historical precedent shows corners markets at such extreme probabilities typically reflect thresholds that are breached in roughly 95% of comparable fixtures.
Traders should monitor team news and tactical adjustments in the weeks preceding the match. Injury absences among key midfielders or full-backs can materially affect pressing intensity and set-piece frequency. Fixture congestion in late April may influence squad rotation decisions, particularly if either side is competing for European qualification or battling relegation. Weather conditions on match day—wind and rain increase corner likelihood—remain a variable to track closer to the settlement window closing on 10 May at 13:00 UTC.
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 "Crystal Palace FC vs. Everton 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.
$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.
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.
