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.

Montedio Yamagata will face Thespa Gunma on 6 May 2026 in the J2 League, Japan's second-tier professional football division. The match is scheduled for 1:00 AM ET, placing it within the settlement window that closes at 05:00 AM ET the same day. This particular market groups additional betting opportunities beyond standard match outcomes, though the specific resolution criteria remain tied to the fixture's result and any official league communications issued before settlement.
The 0% implied probability on Polymarket's order book reflects minimal liquidity or positioning in this market cluster at present. J2 League matches typically attract modest trading volumes outside Japan's domestic betting markets, particularly for secondary or derivative markets. Historical patterns suggest that niche football markets in lower-tier leagues see activity concentrated closer to kick-off, when team news, weather conditions, and late-breaking information become available. The current zero probability may simply indicate an absence of bids rather than strong conviction that the event will not occur.
Traders should monitor official J2 League announcements regarding squad availability, injury updates, or fixture postponements in the days preceding the match. Weather conditions in Yamagata prefecture during early May could affect playing conditions. Any changes to the scheduled kick-off time or venue would require confirmation from the league before settlement. The order book depth will likely increase substantially within 24 hours of the fixture as regional interest and information flow improve.
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 "Montedio Yamagata vs. Thespa Gunma - 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.

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.
