Resolution criteria on PolyGram: More markets for the J2 100 Year Vision League game, scheduled for May 6 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.

Nara Club and FC Ōsaka are scheduled to meet on 6 May 2026 in the J2 League, Japan's second-tier professional football division, with kick-off at 1:00 AM ET. The 0% implied probability on Polymarket's order book reflects either minimal trading activity on this particular market or a consensus that the event specified carries negligible likelihood of occurrence. Given the settlement window closes just hours after the scheduled match, liquidity constraints and late-stage pricing dynamics typically compress order book depth for fixtures in lower-profile leagues.
Historical precedent suggests that J2 League markets on Polymarket have attracted sparse participation relative to top-tier competitions, partly because English-language sports media coverage of the J2 remains limited outside Japan. Comparable second-division football markets across other regions show similar patterns: implied probabilities often remain static at extreme values until significant capital enters the order book, at which point prices can shift sharply. The absence of recent trading activity does not necessarily indicate fundamental certainty about the underlying outcome.
Traders monitoring this market should track any late announcements regarding team lineups, injuries, or weather conditions in the hours before kick-off, as such information typically triggers repricing in low-liquidity markets. The J2 League's official fixture calendar and team announcements remain the primary information sources; mainstream sports news outlets rarely cover these matches in real time. Settlement hinges on the precise wording of the market condition, which should be cross-referenced against official league records once the match concludes.

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 "Nara Club vs. FC Ōsaka - 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.
$3K 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 6 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.

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.
