Spain’s World Cup 2026 triumph followed the path projected more than a month before the final: Argentina reached the decisive match, Spain won it, and the tournament’s probability model had placed La Roja at the top of its forecast.

The projection was built to follow every national team from the group stage through the knockout rounds, rather than offering a single pre-tournament pick. Its final scenario paired Argentina with Spain and gave Spain the edge in the championship match.
Spain ultimately lifted the World Cup, completing a forecast based on Elo ratings, match-by-match win probabilities and 100,000 full-tournament simulations.
How the Elo model measures national teams
Elo is a numerical ranking method first created for chess. Applied to international football, each team holds a rating that rises after victories and falls after defeats. The size of the adjustment depends on the strength of the opponent: beating Argentina carries far more weight than defeating Jordan.
The model uses international-team Elo data from eloratings.net. Its central argument is that Elo offers a more responsive reading of current form than the FIFA ranking, which can be influenced by the volume of matches played and by a longer record that may include numerous low-level friendlies.
Elo ratings change after every result, allowing the calculation to reflect recent official matches. Academic research into forecasting major tournaments has also found Elo-based measures to be more reliable than FIFA rankings for predicting results.
From ratings to World Cup probabilities
For each fixture, the difference between the two teams’ Elo numbers is converted into an expected chance of victory using the standard Elo formula. The calculation also accounts for draws, which are especially relevant during the group phase.
The draw adjustment was calibrated using World Cup results from 1994 through 2022. When two teams have closely matched ratings, the model gives a draw roughly a 33% chance. Once the Elo gap is greater than 400 points, the chance of a draw falls below 10%.
| Example fixture | Elo rating | Rating gap | Model outcome |
|---|---|---|---|
| Spain | 2,155 | 734 points | Spain win: 86% to 88%; draw: below 6% |
| Qatar | 1,421 |
In that Spain-Qatar example, an upset remains possible, but the rating gap makes it highly unlikely within the model.
What a team’s title percentage represents
Each round-by-round percentage comes from 100,000 simulated versions of the entire World Cup. Every match is assigned a result at random, but those results are weighted by the calculated probabilities.
If Argentina is shown with a 15% chance of becoming champions, that means Argentina won 15,000 of the 100,000 simulations. The figure is not a guarantee or a definitive prediction; it measures relative likelihood based on the teams’ ratings at that point in the international calendar.
The ratings are refreshed automatically each morning, ensuring that the tournament outlook incorporates each team’s latest official results. In 2026, that process pointed to an Argentina-Spain final and Spain’s eventual World Cup title.
