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.
Market outcomes
| West Ham United FC | 17% YES | 84% NO |
| Draw (West Ham United FC vs. Arsenal FC) | 23% YES | 78% NO |
| Arsenal FC | 63% YES | 38% NO |
West Ham United will host Arsenal at the London Stadium on Sunday, 10 May 2026 in a Premier League fixture. The current order book on Polymarket reflects a 17% implied probability for a West Ham victory, with the remaining probability distributed between an Arsenal win and a draw. This pricing emerges from real-time trading activity and represents the aggregate view of market participants positioned across the contract's lifecycle.
Historically, West Ham's home record against Arsenal has been mixed, though Arsenal have won the majority of recent encounters. In the 2024–25 season, Arsenal sit higher in the league table and command superior odds in most betting markets, consistent with Polymarket's current pricing. The 17% probability for West Ham aligns with their status as significant underdogs, reflecting both their relative league position and the difficulty of securing three points against a top-four contender at this stage of the season.
Traders should monitor team news, injury updates, and final league standings as the fixture approaches. Arsenal's European commitments or fixture congestion in late April could affect squad rotation and form. West Ham's own mid-table positioning and any managerial or personnel changes will influence their tactical approach. The settlement window closes at 15:30 GMT on match day, giving traders approximately one week to adjust positions based on emerging information about team selection and pre-match conditions.
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 "West Ham United FC vs. Arsenal FC" 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.
$181K in lifetime turnover and $3.0M of resting liquidity puts this market in the top 30% by volume for sports contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
Last 24 hours alone saw $105K 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.
