Resolution criteria on PolyGram: More markets for the J1 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.

Vissel Kōbe will face Fagiano Okayama on 10 May 2026 in a J1 League fixture as part of Japan's centennial season competition. The match is scheduled for 1:00 AM ET, reflecting the time zone difference for a domestic Japanese league game. The current 0% implied probability on Polymarket's order book suggests no traders are currently willing to back the "More Markets" outcome at any price, indicating either extreme confidence in the alternative or minimal liquidity formation at present.
The J1 League has historically seen consistent fixture scheduling and market availability across major betting platforms. Comparable domestic league matches in Japan typically generate secondary market activity once primary fixtures are confirmed and team news emerges. The absence of current probability formation here reflects the settlement window's distance and the specificity of the market condition—traders may be awaiting clearer information about match circumstances before committing capital to related derivative markets.
Catalysts for probability movement will include official team news, injury announcements, and confirmation of whether additional betting markets open through major sportsbooks in the coming weeks. The J1 League's fixture calendar is typically finalised months in advance, so scheduling changes are unlikely. Traders should monitor whether Vissel Kōbe or Fagiano Okayama experience significant roster changes or managerial shifts before May, as these could influence broader market interest and secondary market creation. The settlement window closes 10 May at 05:00 UTC, allowing approximately one month for market development.
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 "Vissel Kōbe vs. Fagiano Okayama - 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.
$55K 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 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.
