Resolution criteria on PolyGram: This event is for the upcoming J1 100 Year Vision League game, scheduled for Sunday, May 10, 2026 between Yokohama F·Marinos and Kashima Antlers.
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.
Market outcomes
| Yokohama F·Marinos | 0% YES | 100% NO |

| Kashima Antlers | 0% YES | 100% NO |
Yokohama F·Marinos will face Kashima Antlers in a J1 League fixture on 10 May 2026, part of the J1 100 Year Vision League season. The match represents a standard domestic league encounter between two established Japanese clubs with contrasting recent form trajectories. Kashima Antlers have historically been one of Japan's most successful sides, whilst Yokohama F·Marinos have shown competitive consistency in recent seasons. The current 0% implied probability on Polymarket's order book suggests minimal trading activity or a structural issue with how the market is pricing this fixture.
Historical context shows that J1 League matches between mid-table and top-tier sides typically see implied probabilities reflecting genuine uncertainty rather than extreme valuations. Kashima's domestic record and Yokohama's recent performances should ordinarily generate meaningful probability ranges across win, draw, and loss outcomes. The zero reading here warrants scrutiny—it may reflect low liquidity, settlement specification ambiguity, or a technical constraint in how the market is denominating outcomes.
Traders should monitor squad announcements through April 2026, particularly regarding injury status for key players at both clubs. Fixture congestion in the lead-up to May, including any AFC Champions League commitments, will influence team selection and fatigue levels. Recent form data and head-to-head records from the 2025 season will become increasingly relevant as the match approaches. The settlement window closes 05:00 UTC on 10 May, allowing only post-match confirmation for final resolution.
This market settles from the official outcome published at https://www.jleague.jp/en/. 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 "Yokohama F·Marinos vs. Kashima Antlers" 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.
$176K in lifetime turnover and $244K 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 $176K 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.
