Resolution criteria on PolyGram: More markets for the Eredivisie game, scheduled for May 17 at 8:30 AM 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.

NEC and Go Ahead Eagles are scheduled to meet in the Eredivisie on 17 May at 8:30 AM ET, with settlement contingent on whether additional markets for this fixture will be created on Polymarket. The current order book reflects a 46% implied probability of YES, indicating meaningful uncertainty amongst traders about whether supplementary betting opportunities will materialise around this match.
Comparable Polymarket fixtures from the Eredivisie suggest that secondary markets tend to emerge for matches involving higher-profile clubs or those with significant playoff implications. NEC finished the 2023–24 season in mid-table, whilst Go Ahead Eagles similarly occupy a peripheral position in the league hierarchy. Historical precedent indicates that markets proliferate around relegation-battle or European-qualification scenarios; absent such stakes, fixture-specific secondary markets often remain sparse. The current 46% probability reflects this baseline scepticism about market expansion for a routine mid-table encounter.
Traders should monitor Polymarket's own market-creation activity in the weeks preceding 17 May, as the platform's operational decisions drive settlement directly. Fixture postponements or rescheduling would alter the timeline substantially. Additionally, any late-season developments affecting either club's league position—injury crises, managerial changes, or unexpected competitive relevance—could influence whether Polymarket deems the match sufficiently noteworthy to warrant additional markets. The settlement window closes at 12:30 UTC on 17 May, providing a narrow window for market creation decisions post-match.
This market settles from the official outcome published at https://eredivisie.nl/competitie/speelschema. 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 "NEC vs. Go Ahead Eagles - 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 $100K of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is exceptional — among the deepest order books in the category.
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.
