Resolution criteria on PolyGram: More markets for the J2 100 Year Vision League game, scheduled for May 10 at 2:00 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.

Ehime FC and Kataller Toyama are scheduled to meet on 10 May 2026 in the J2 League, Japan's second-tier professional football division. The match kicks off at 2:00 AM ET, forming part of the J2 100 Year Vision League season. The 0% implied probability on Polymarket's order book reflects minimal trading activity or consensus around whatever specific outcome this market is measuring, likely owing to the fixture's distance from settlement and the niche appeal of Japanese second-division football among prediction market participants.
J2 League matches typically attract modest liquidity on international prediction platforms, particularly when settlement windows extend several months into the future. Historical precedent suggests that markets on lower-tier Asian football competitions often remain thin until the week preceding the match, when relevant team news, injury updates and weather conditions crystallise. The current zero probability may simply indicate an absence of early positioning rather than strong conviction that the outcome cannot occur.
Traders should monitor Ehime FC and Kataller Toyama's league standings, fixture congestion and squad rotation patterns as the May fixture approaches. Japanese football media outlets including Goal Japan and official J-League communications typically release team news three to five days before matches. Polymarket's order book may see activity spike once the clubs' form trajectories become clearer and as the settlement window narrows, particularly if either side enters the match with significant injury concerns or playoff implications.
