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.

Giravanz Kitakyūshū and Roasso Kumamoto will meet on 6 May 2026 in the J2 League, Japan's second-tier professional football division. The 0% implied probability on Polymarket's order book reflects either sparse liquidity in this particular market cluster or a genuine absence of traders willing to back the "More Markets" outcome at any price. The settlement window closes at 05:00 UTC on 6 May, shortly after the scheduled 06:00 UTC kick-off, meaning resolution depends on rapid confirmation of match-related data and the availability of additional betting markets.
Historical precedent suggests that J2 League matches, particularly those involving mid-table sides like Kitakyūshū and Kumamoto, typically generate secondary market activity only when fixtures involve promotion contenders or carry playoff implications. The 100 Year Vision League designation indicates a special tournament format within Japan's football calendar, which may limit the proliferation of derivative markets compared to standard league play. Prior J2 fixtures have shown variable market depth depending on domestic broadcast reach and international betting interest.
Traders should monitor J2 League official announcements regarding broadcast partnerships and betting operator approvals in the days preceding the match. Kumamoto's recent form and any squad rotation decisions will influence bookmaker appetite for ancillary markets. The tight settlement window—closing before full-time whistle confirmation—creates execution risk; order book depth on Polymarket today will signal whether institutional or retail traders expect meaningful secondary market creation by match day.
Giravanz Kitakyushu is a Japanese football club based in Kitakyushu, Fukuoka Prefecture. They currently play in J3 League, Japanese third tier of professional league football.
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 "Giravanz Kitakyūshū vs. Roasso Kumamoto - 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 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.
