Prediction markets currently give a 28% probability that Will Japan win Group F in the 2026 FIFA World Cup?. This contract trades at 28¢ on Polymarket, closing June 27, 2026. Japan's 29¢ price reflects a modest 29% win probability for Group F, though the extremely high 1259% implied yield on the Yes side suggests significant underpricing relative to the market's volatility expectations—potentially indicating either contrarian positioning or uncertainty about Group F composition.

Analysis

4d ago

Japan's 29¢ price reflects a modest 29% win probability for Group F, though the extremely high 1259% implied yield on the Yes side suggests significant underpricing relative to the market's volatility expectations—potentially indicating either contrarian positioning or uncertainty about Group F composition. With $447k in 24-hour volume against $19.7M open interest and a tight 2¢ spread, liquidity is moderate but the 322% realized volatility and neutral regime (0.341 score) point to genuine uncertainty rather than consensus pricing. The market has remained flat at 29¢ over seven days despite 71 days to expiry and a low 0.3/h information arrival rate, suggesting limited new catalyst flow until closer to the tournament or group stage draw confirmation.

Resolution rules

This market will resolve according to the team that wins Group F in the 2026 FIFA World Cup group stage, scheduled for June 11-27, 2026. If multiple teams tie as group winners, this market will resolve according to the official tiebreak procedure of the 2026 FIFA World Cup. If the World Cup group stage is cancelled, postponed after September 30, 2026, or there is otherwise no winner declared for this group within that timeframe, this market will resolve to “Other”. The primary resolution source for this market will be official information from FIFA (https://www.fifa.com/); however, a consensus of credible reporting may also be used.
