Resolution criteria on PolyGram: More markets for the J2 100 Year Vision League game, scheduled for May 10 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. 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.

Roasso Kumamoto and FC Ryūkyū are scheduled to meet on 10 May 2026 in the J2 League, Japan's second tier professional football division. The match kicks off at 1:00 AM ET, with settlement closing at 05:00 UTC the same day. This represents one of several derivative markets Polymarket has opened around the fixture, allowing traders to position on outcomes beyond the standard match result.
The 0% implied probability currently displayed on Polymarket's order book reflects minimal liquidity and no active bids at any price level for this particular market variant. J2 League matches typically attract modest trading volumes on prediction platforms, particularly for supplementary markets rather than core outcomes. Historical precedent suggests that secondary markets around lower-tier Japanese football fixtures remain thinly traded until closer to match day, when information asymmetries narrow and casual interest peaks. The settlement window's tight closure—just four hours after kick-off—further constrains participation from traders unable to monitor real-time developments.
Traders monitoring this fixture should track official J2 League announcements regarding team lineups, injury updates and weather conditions in the days preceding 10 May. Recent squad news from either club's official channels or Japanese football media outlets will inform whether material changes to competitive balance emerge. Fixture scheduling and any fixture congestion affecting either side's preparation warrant attention, as does confirmation of the exact match venue and any late administrative changes. The current zero-probability reading likely reflects absence of market-making activity rather than genuine certainty about the outcome.
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 "Roasso Kumamoto vs. FC Ryūkyū - 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.
$6K in lifetime turnover and $0 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.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 10 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.
