Resolution criteria on PolyGram: More markets for the J2 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.

Ōita Trinita and Sagan Tosu will meet in the J2 League on 10 May 2026, with additional betting markets now available on Polymarket tracking various match outcomes and performance metrics. The J2 100 Year Vision League represents Japan's second tier, where both clubs compete for promotion and domestic standing. Settlement occurs at 05:00 UTC on 10 May, shortly after the scheduled 01:00 ET kick-off.
The current 0% implied probability on Polymarket's order book reflects minimal liquidity or consensus pricing for the "More Markets" category rather than certainty of outcome. J2 League fixtures typically attract modest trading volumes compared to top-tier competitions, and secondary market categories often show extreme probabilities simply due to sparse order book depth. Historical patterns suggest that as settlement approaches and match details crystallise—team news, injury updates, weather conditions—probability distributions tend to normalise across related markets.
Traders should monitor official J2 League fixture confirmations, squad announcements from both clubs, and any schedule changes through early May. Recent fixture data from the J2 League's official channels will clarify final team lineups and conditions. Sagan Tosu's recent form and Ōita Trinita's current league position will inform relative expectations. The extended settlement window allows for real-time adjustments as match day approaches, though the niche category nature suggests order book activity may remain limited until closer to kick-off.
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 "Ōita Trinita vs. Sagan Tosu - 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.
$6K 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 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.
