FIFA World Cup 2026: what the model is seeing
The 2026 World Cup is the first 48-team tournament. More group games, more variance, more chances for upsets - and more data for the model to chew on once we're a couple of matchdays in.
The opener: Mexico vs South Africa
Mexico at home, in front of a partisan Estadio Azteca crowd. The model puts Mexico at 58% to win, draw at 23%, South Africa at 19% - broadly aligned with consensus markets but slightly higher on Mexico's expected goals (1.8 vs the market's 1.6).
The key variable: how Mexico handles the altitude advantage in a 90-minute opener with World Cup nerves. Historically, hosts in opening matches score about 0.3 xG above their season average.
Three teams the model rates higher than the market
- Morocco. The 2022 semifinalists still have the same defensive structure. The model gives them a 14% chance to make the quarters vs. the market's 9%.
- Uruguay. Bielsa's pressing system shows up in pressing intensity metrics. Expected goals against is the second-lowest in CONMEBOL qualifying.
- Japan. Quietly built a squad that scores from set pieces (top-3 in Asia for set-piece xG) - a feature that historically outperforms its underlying numbers at World Cups.
Three teams the model is fading
- Brazil. Still favourites, but the model has them at 13% to win it outright vs. the market's 16%. The defensive numbers don't justify the price.
- England. Tournament football flattens England's possession advantage. The model gives them 8% to win it.
- Germany. Improved since 2022 but still ranked below their FIFA standing in our underlying xG model.
What to watch in matchday 2
The expanded format means group-stage matchday 2 is when the real signal arrives. Teams have shown a hand, line-ups are settled, and the model starts trusting in-tournament data. Expect bigger shifts in our confidence scores between matchday 1 and matchday 2 than at any other point in the tournament.
