World Cup 2026 Winner Has Already Been Decided

 

With nine days until Mexico open the 2026 World Cup against South Africa, Opta has published its first full pre-tournament forecast, simulating all 104 matches 10,000 times. Spain come out as the most likely winners, taking the trophy in 16.1% of those runs. 

A tight big four at the top

Spain (16.1%) sit just ahead of France (13.0%), England (11.2%) and Argentina (10.4%). Turn those probabilities into fair odds and the four trade between 6.21 and 9.62. The market is shorter still on the front three, with Spain around 5.50, France around 6.00 and England around 7.00, so the bookmakers are pricing the favourites more aggressively than the model is. Argentina is the one name where the two broadly agree, model and market both sitting close to 9.0.

Why the model rates Spain

Spain are the only side rated more likely than not to reach the quarter-finals, clearing that stage 52.1% of the time, reaching the semis in 39.0% of runs and the final in 25.6%. A Group H draw alongside Uruguay, Saudi Arabia and Cape Verde helps, with Spain topping it in 75.3% of sims. The caveat is Lamine Yamal, whose hamstring leaves his availability for the opening games uncertain. He went into the season as the most productive creator in La Liga bar Mbappé, so the timing of his return matters to the projection.

Portugal, Brazil and Germany lead the chasing pack

Below the top four, Opta has Portugal at 7.0%, Brazil at 6.6% and Germany at 5.1%, three sides separated by next to nothing. Brazil open against Morocco on 13 June, the standout fixture of the opening week and a meeting of the highest-rated African team with a Seleção side the model expects to win Group C 60.4% of the time. Ancelotti has named Neymar despite a calf strain, alongside Vinícius Júnior, Raphinha and Matheus Cunha.

The dark horses

Five teams occupy genuine outsider territory: Netherlands (3.6%), Norway (3.5%), Belgium (2.4%), Colombia (2.1%) and Morocco (1.9%). Norway’s qualifying numbers stand out, with 37 goals in eight games and 16 from Haaland, though Opta notes that both they and the Netherlands face awkward groups that could hand them a tougher knockout route if they fail to finish top.

What the spread actually shows

The more useful figure is the shape of the distribution, not the name at the top. Only 35.9% of the 10,000 runs produced a first-time winner. Australia came out on top 28 times, Scotland 22, and even Haiti, the lowest-rated team in the field, won it once. Curaçao were the only nation never to lift the trophy across all 10,000 simulations.
