Resolution criteria on PolyGram: More markets for the FIFA International Friendlies game, scheduled for May 30 at 7:30 PM ET.
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.

Ecuador and Saudi Arabia are scheduled to meet in a FIFA International Friendly on 30 May 2026 at 7:30 PM ET. The current order book on Polymarket prices this market at 40% YES, reflecting moderate confidence in the proposition's resolution. International friendlies typically draw lower trading volumes than competitive fixtures, which can result in wider spreads and less efficient pricing discovery compared to World Cup or continental championship matches.
Historical precedent suggests friendly matches between South American and Asian sides carry considerable uncertainty. Ecuador, a consistent Copa América participant with established CONMEBOL infrastructure, generally fields competitive squads in non-binding fixtures. Saudi Arabia, conversely, has shown volatility in friendly performance, with results often reflecting preparation cycles ahead of Asian Cup or World Cup qualifiers. The 40% probability on Polymarket's order book indicates traders perceive meaningful doubt about the outcome, though the specific resolution criteria—whether this concerns match result, goals, or another metric—should be verified against the market's settlement rules.
Traders should monitor squad announcements and injury reports as the May fixture approaches, particularly regarding Ecuador's Copa América preparation schedule and Saudi Arabia's domestic league calendar. Friendly matches often see rotated lineups, which can significantly alter competitive balance. Any late fixture cancellations or rescheduling would trigger settlement mechanics. Recent friendly results between these nations remain sparse, making comparable historical data limited; traders may reference broader CONMEBOL versus AFC performance differentials to calibrate expectations.
This market settles from the official outcome published at https://www.fifa.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 "Ecuador vs. Saudi Arabia - More Markets" 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.
$0 in lifetime turnover and $1K 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.
Resolution is sourced from https://www.fifa.com. Settlement is executed by the UMA optimistic oracle on Polygon, with a 2-hour dispute window before payouts clear.
This prediction market is scheduled to close on 30 May 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

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.
