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.

Kataller Toyama and Kamatamare Sanuki are scheduled to meet in the J2 League on 6 May 2026, with additional markets now available for trading on Polymarket covering this fixture. The J2 League represents Japan's second tier of professional football, featuring 20 clubs competing in a single round-robin format across the calendar year. The 0% implied probability reflected in the current order book suggests minimal trading activity or consensus pricing on these supplementary markets at present, which is typical for niche sports betting instruments opened well in advance of fixture settlement.
Historical precedent in J2 League markets shows that probability formation often remains sparse until 7–10 days before match day, when team news, injury reports and tactical announcements crystallise trader conviction. Comparable secondary markets for lower-tier Japanese football have demonstrated sharp repricing once official squad lists are confirmed and weather conditions become forecastable. The current null probability likely reflects the absence of meaningful order flow rather than genuine market consensus.
Traders should monitor official J2 League communications regarding team availability and any fixture rescheduling announcements, which occasionally occur in Japanese football due to weather or administrative changes. Recent fixture data from the J2 League's official website and team social media channels will provide injury updates and squad rotation signals in the fortnight preceding match day. Settlement occurs at 05:00 UTC on 6 May, immediately following the scheduled 01:00 ET 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 "Kataller Toyama vs. Kamatamare Sanuki - 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.
$22K in lifetime turnover and $0 of resting liquidity puts this market in the around 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.

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.
