Spain and France Lead the Board
On Polymarket, as of 3:30 p.m. EDT on June 10, 2026, Spain’s “Yes” shares are trading at 16.5 cents, implying a 16.5% probability of winning the tournament. France sits just behind at 16.1 cents. England and Portugal each hold an 11% chance, while defending champion Argentina sits at 9% and Brazil at 8%.
Polymarket’s World Cup winner market alone has drawn $1.9 billion in volume since opening on July 2, 2025. Kalshi’s version of the same market has added another $132 million, pushing the combined total across both platforms past $2 billion between those two contracts alone. The $2 billion milestone was first logged two days ago between the two Kalshi and Polymarket events, and dollars keep pouring in.

Traditional sportsbooks align with the prediction markets. Spain is priced at +450 to +480 across BetMGM, Fanduel, and Draftkings. France sits at +475 to +550, with England at +650 to +700. At +450, Spain carries an implied win probability of roughly 18%.
Thursday’s Opening Matches
The tournament begins June 11 with Mexico facing South Africa at 3:00 PM and Korea Republic taking on Czechia at 10:00 PM.
Mexico enters as the heaviest individual-match favorite on Polymarket’s opening slate, with their win shares trading at 70 cents against South Africa’s 11 cents. That matchup has also drawn the most liquidity of the four opening games, with $1.86 million in total volume.

Friday’s Slate
Canada faces Bosnia-Herzegovina Friday at 3:00 PM with a 54% win probability, while the United States opens against Paraguay at 9:00 PM at dead-even odds: USA at 50 cents, Paraguay at 23 cents, and the draw at 29 cents. The U.S. match has drawn $565,840 in volume.
Handicap and Goals Markets
Across all four opening matches, Polymarket‘s total goals markets lean toward the under. The “Under 2.5 goals” outcome carries a 57% to 59% implied probability in every fixture. The handicap lines further confirm Mexico’s favoritism: Mexico -1.5 goals is priced at 41 cents, while South Africa +1.5 goals sits at 60 cents.
Tournament Format and Stakes
The 2026 edition is the largest World Cup in tournament history. FIFA expanded the field to 48 teams across 12 groups, with the top two finishers in each group plus the eight best third-place teams advancing to a 32-team knockout bracket. The tournament runs through July 19, 2026, with the final scheduled at Metlife Stadium in the New York/New Jersey area.
Prediction market odds shift fast once group play begins. Portugal has shortened on public betting interest in recent days, while England and Brazil have drifted slightly at several books. Spain and France have held firm as the dual market leaders heading into the opening weekend.
