Strong European and South American sides like Spain, France, England, and Brazil sit at 76-80% implied probability to advance from their groups in the expanded 48-team 2026 World Cup, reflecting early group-stage results and historical consistency. With 12 groups of four and the top two plus eight best third-placed teams progressing to the round of 32, recent opening-match performances have clarified paths for many contenders while leaving others in tighter races. Key variables include remaining fixtures, goal differential, and potential upsets from mid-tier sides; teams with superior squad depth and recent qualifying form hold clearer edges. Late injuries, rest management, or surprising results from underdogs could still shift advancement odds before the group stage concludes June 27.
