Resolution criteria on PolyGram: More markets for the J1 100 Year Vision League game, scheduled for May 6 at 2:00 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.

Sanfrecce Hiroshima and Vissel Kōbe will meet in the J1 League on 6 May 2026, with the match scheduled for 02:00 ET. This fixture sits within Japan's top-flight domestic competition, the J-League Division 1, which operates under the "100 Year Vision" strategic framework adopted by the league. The 0% implied probability on Polymarket's order book suggests minimal trading activity or consensus that additional derivative markets for this fixture will not materialise before the settlement window closes.
Historical precedent shows that secondary markets for J-League fixtures typically emerge only when primary betting liquidity reaches threshold levels or when major bookmakers signal intent to offer extended markets. Comparable fixtures between mid-table and upper-tier J1 sides have generated ancillary markets only sporadically, particularly when international broadcast rights holders or regional sportsbooks commit capital. The current zero probability reflects the baseline expectation that no such secondary markets will be formally listed before the match concludes.
Traders should monitor J-League official announcements regarding broadcast partnerships and any expansion of betting markets by licensed operators in Japan or internationally. Vissel Kōbe's recent performance trends and Hiroshima's league standing will influence whether major sportsbooks judge the fixture commercially viable for extended wagering products. The settlement window's closure at 06:00 ET on 6 May—four hours after kickoff—leaves minimal opportunity for late-stage market activation, making early catalyst detection critical for any position adjustment.
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 "Sanfrecce Hiroshima vs. Vissel Kōbe - 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.
$60K 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.
The market has been open for around 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.

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.
