2026 年 7 月 19 日 · MetLife Stadium，新泽西
32 强
2026-06-28 – 2026-07-03 · 16 matches
The 32 group-stage advancers (24 group winners + runners-up + 8 best thirds) face off across 16 matches.
16 强
2026-07-04 – 2026-07-07 · 8 matches
The traditional Round of 16. Polymarket lists per-match markets the day each fixture is set.
四分之一决赛
2026-07-09 – 2026-07-11 · 4 matches
Quarter-finals — historically the deepest arbitrage edge per match because volume spikes and books occasionally over-correct.
半决赛
2026-07-14 – 2026-07-15 · 2 matches
Semi-finals. Per-match markets, both-teams-to-score markets, and a re-priced tournament-winner market all run in parallel — fertile for combinatorial arbitrage.
季军争夺战
2026-07-18 · 1 match
Third-place play-off — small, often illiquid market, occasionally produces large spreads when bots withdraw.
决赛
2026-07-19 · 1 match
The 2026 FIFA World Cup Final at MetLife Stadium, New Jersey. The single biggest Polymarket fixture of the year.
