39% — Will Japan advance further than Korea Republic in the 2026 Men's FIFA World Cup Kalshi 39% · 20 contracts · $15K volume · medium confidence Updated 2026-06-19 17:59:13 UTC Why this matters: This contract reflects a 23% probability that Japan will advance further than South Korea in the 2026 FIFA World Cup. Japan enters as a higher-ranked team with recent strong tournament performances, while Korea Republic also qualifies regularly but faces tougher group stage dynamics this cycle. The probability would shift based on official group draw results, team roster announcements, and pre-tournament form. The World Cup takes place in June-July 2026, at which point the contract resolves based on which team progresses further in the knockout stage—or is eliminated earlier. Current odds suggest market participants view Japan as the likely deeper performer, though Korea's qualification demonstrates competitive capacity to potentially disrupt that expectation. Key factors: - Japan's FIFA ranking and recent World Cup performance history versus Korea Republic's qualification track record and group stage strength - The specific group assignments and opponent quality each team faces in the tournament draw - Injury status and player availability of key performers on both squads during the pre-tournament period - Head-to-head strength in 2022 World Cup performance and subsequent qualification campaigns - Weather, altitude, and scheduling factors that emerge closer to June 2026 that could disproportionately affect either team's knockout stage progression Contracts: - Will France advance further than Portugal in the 2026 Men's FIFA World Cup?: France advances further than Portugal — 62¢ Kalshi $2K (weight 16%) - Will Mexico advance further than USA in the 2026 Men's FIFA World Cup?: Mexico advances further than USA — 30¢ Kalshi $2K (weight 14%) - Will Japan advance further than Korea Republic in the 2026 Men's FIFA World Cup?: Japan advances further than Korea Republic — 34¢ Kalshi $2K (weight 14%) - Will Germany advance further than Belgium in the 2026 Men's FIFA World Cup?: Germany advances further than Belgium — 58¢ Kalshi $1K (weight 9%) - Will USA advance further than Mexico in the 2026 Men's FIFA World Cup?: USA advances further than Mexico — 48¢ Kalshi $1K (weight 9%) - Will Argentina advance further than Brazil in the 2026 Men's FIFA World Cup?: Argentina advances further than Brazil — 63¢ Kalshi $1K (weight 9%) - Will Netherlands advance further than Norway in the 2026 Men's FIFA World Cup?: Netherlands advances further than Norway — 40¢ Kalshi $749 (weight 5%) - Will Korea Republic advance further than Japan in the 2026 Men's FIFA World Cup?: Korea Republic advances further than Japan — 39¢ Kalshi $621 (weight 4%) - ... and 12 more --- ## Methodology SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged.
