World Cup 2026: Who Wins According to AI? Spain, France and Argentina Lead Every Simulation

The 2026 World Cup kicks off today, and AI models have already played out the entire tournament thousands of times. The consensus? Europe dominates the podium, but the margins are razor-thin.

Spain leads every major AI simulation for the World Cup

Opta's supercomputer ran 25,000 simulations and crowned Spain the top favorite at 16.1% probability. ChatGPT, fed with FIFA rankings, qualifying results, injury reports and travel schedules, also projects La Roja lifting the trophy.

When Decrypt tested seven state-of-the-art AI agents, four picked Spain and three picked Argentina. Lamine Yamal keeps showing up as the X-factor across every model. At 18, the kid is already an algorithm magnet.

France and Argentina: the AI's closest challengers

French data consultancy AVISIA puts France and Argentina in a dead heat at 21% each. Les Bleus get there on the back of Mbappé, Dembélé and Olise's offensive firepower, paired with top-tier athletic freshness.

Sportsbooks tell a similar story: Spain leads at +450, France follows at +475, then England (+700), Brazil and Argentina at +950. RotoWire's Gemini-powered model gives France a tournament-high 20% win rate after 100 simulations, so the top three really depends on which numbers you trust.

Why AI still can't crack the World Cup

The expanded 48-team format creates more matches, more travel, and more opportunities for upsets than any tournament before. Six weeks of football across three countries is a logistical puzzle no Elo rating can fully capture.

In 2022, the same Opta AI had Brazil as the clear favorite at 16%. The Seleção was knocked out in the quarterfinals by Croatia. Algorithms set the table, but football flips it.
