Resolution criteria on PolyGram: More markets for the J1 100 Year Vision League game, scheduled for May 9 at 1:00 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.

FC Mito Holly Hock will face Urawa Red Diamonds on 9 May 2026 in a J1 League fixture, with kickoff scheduled for 1:00 AM ET. This market captures additional betting opportunities beyond standard match outcomes, likely covering goal totals, player performances, or other in-play events specific to this fixture. The 0% implied probability on Polymarket's order book suggests either extremely low liquidity in this particular market segment or that current bids reflect minimal perceived likelihood of the specified outcome occurring.
J1 League matches between mid-table and established sides typically generate modest trading volumes on derivative markets, particularly for secondary outcomes. Urawa Red Diamonds, a historically prominent club, generally command stronger odds in most market conditions compared to Holly Hock. The current zero probability reading often indicates a gap between the best bid and ask on the order book—a common occurrence in lower-liquidity prediction markets where no trader has yet committed capital at the asking price.
Traders monitoring this market should track team news releases and official J1 League communications through early May, particularly injury updates or squad rotation announcements that might affect the specific outcome being priced. Weather conditions and pitch reports closer to the fixture date can shift probabilities for markets tied to goal-scoring or performance thresholds. The settlement window closes at 05:00 UTC on 9 May, allowing roughly four hours post-match for final resolution based on official league records.
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 "FC Mito Holly Hock vs. Urawa Red Diamonds - 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.
$69K in lifetime turnover and $0 of resting liquidity puts this market in the above 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.
Last 24 hours alone saw $69K 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.
Resolution is sourced from https://www.jleague.jp/en/. 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 9 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.
