Resolution criteria on PolyGram: This event is for the upcoming J1 100 Year Vision League game, scheduled for Saturday, May 16, 2026 between Yokohama F·Marinos and Kashiwa Reysol.
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.
Market outcomes
| Yokohama F·Marinos | 31% YES | 69% NO |
| Draw (Yokohama F·Marinos vs. Kashiwa Reysol) | 28% YES | 73% NO |
| Kashiwa Reysol | 40% YES | 60% NO |
Yokohama F·Marinos will face Kashiwa Reysol in a J1 League fixture on Saturday, 16 May 2026, as part of the league's centenary season. The current order book on Polymarket reflects a 35% implied probability for the YES outcome, suggesting traders are pricing in either a draw or a Reysol victory as moderately likely. This probability has formed through active trading across the book's depth, with the spread between bid and ask orders indicating moderate confidence in the near-even matchup.
Historically, Yokohama F·Marinos have held a slight edge in head-to-head records against Kashiwa Reysol, though recent seasons have seen competitive encounters between the two clubs. Both sides have experienced fluctuating form across the 2025 campaign, making historical win rates less predictive than usual. Kashiwa's home record and Yokohama's away performance in the current season will likely anchor trader positioning, particularly given the fixture's location and timing within the league calendar.
Traders should monitor team news regarding injuries to key players, managerial changes, and any fixture congestion from continental competitions in the weeks preceding 16 May. Recent J1 League standings and form tables will shift market pricing as the settlement window approaches. Weather conditions at the venue and any late tactical announcements from either club could trigger order book movement closer to kickoff. The centenary season context may also influence squad rotation decisions by either manager.
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.
