Resolution criteria on PolyGram: More markets for the J2 100 Year Vision League game, scheduled for May 17 at 5:00 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.

FC Ryūkyū will face Gainare Tottori in the J2 League on 17 May 2026 at 5:00 AM ET. The J2 100 Year Vision League is Japan's second tier, featuring 20 clubs competing in a single round-robin format across the calendar year. This fixture represents a mid-season encounter in what is typically a competitive division where form, injury status, and recent results carry substantial weight in match outcomes.
The current order book on Polymarket reflects a 32% implied probability for the "More Markets" outcome, suggesting traders are pricing in a moderately low likelihood of additional betting markets materialising for this specific fixture. Historical precedent in J2 League trading shows that market expansion often correlates with fixture prominence—higher-profile clubs or playoff-adjacent matches typically attract secondary market creation. Ryūkyū and Tottori are mid-table sides without the commercial pull of J-League Division 1 clubs, which contextualises the restrained probability. Comparable J2 fixtures have seen additional markets opened only when broader betting interest or promotional activity from platforms warranted the operational effort.
Traders should monitor J2 League scheduling announcements and any platform-level decisions regarding market expansion in early May. Recent fixture calendars and team performance trajectories through April will inform whether either club's playoff positioning creates sufficient trading volume to justify supplementary markets. Polymarket's order book depth on this contract will also signal whether institutional interest is building ahead of the settlement window closing on 17 May at 09:00 UTC.
FC Ryukyu Okinawa is a Japanese professional football club based in Okinawa. The club plays in the J3 League, Japanese third tier of professional football. The team's home stadium is Okinawa Athletic Park Stadium, in Okinawa Prefecture, Japan.
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 "FC Ryūkyū vs. Gainare Tottori - 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.
$0 in lifetime turnover and $8K 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 17 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.

When the outcome is determined, winning YES shares pay out $1.00 each in USDC, while losing shares pay $0.

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.
