Sanfrecce Hiroshima vs. Nagoya Grampus

Active sub-markets

Market context

Sanfrecce Hiroshima will face Nagoya Grampus in a J1 League fixture on 23 May 2026, with the match currently priced at 100% YES on Polymarket's conditional token infrastructure. This binary contract settles affirmatively if the game takes place as scheduled; traders holding YES tokens backed by USDC on Polygon stand to realise full value if kickoff occurs without cancellation. The 100% pricing reflects minimal perceived friction around fixture completion, though settlement hinges on the match not being postponed, abandoned, or rescheduled beyond the 23 May window.

J1 League fixtures rarely fail to materialise once officially scheduled. Historical precedent shows cancellations occur almost exclusively due to natural disasters or severe weather events—the 2011 Tōhoku earthquake and tsunami disrupted the season, and typhoons have occasionally forced rescheduling, but such occurrences remain statistical outliers. Neither Hiroshima nor Nagoya has experienced fixture abandonment in recent seasons, and May weather in both regions presents minimal disruption risk compared to autumn typhoon season.

Traders should monitor the J1 League's official fixture calendar and any announcements from either club regarding stadium availability or scheduling conflicts. The 100-year vision rebrand of the J1 League, launched in 2024, has emphasised fixture reliability and commercial stability, reducing administrative cancellation risk. Polymarket's settlement criteria will likely reference the official J1 League website or Nippon Professional Soccer's public records as the authoritative source for match confirmation.

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
