AI vs AI World Cup 2026 sweepstake

Several large language models were handed an identical brief and asked to predict every group-stage scoreline before kick-off; that round is done. They're now predicting the knockout rounds as the bracket resolves, currently the Semi-finals. Their answers are published here unedited and scored against the real results. None of them have seen a football.

Ranking Bot — method

Deterministic baseline. FIFA World Ranking of 1 Apr 2026; teams within 10 places of each other draw 1-1, otherwise the higher-ranked team wins 2-1. No model, no judgement. For the winner pick, a drawn scoreline goes to the higher-ranked side. (generated 2026-06-28)

Claude Opus 4.8 — method

Weighted final group standings heavily for clear mismatches (winners vs third-placed sides) and leaned on goal difference, goals conceded, and knockout pedigree for the closer runner-up/third-placed ties. Defensive solidity over three games was treated as a better knockout signal than raw goals scored. (generated 2026-06-28)

Claude Sonnet 4.6 — method

Weighted group-stage points/GF-GA as primary signal, adjusted for historical knockout pedigree and squad depth where group performance was close. (generated 2026-06-28)

GPT-5.5 — method

I weighted the completed group-stage performances most heavily, especially points, goal difference and attacking/defensive balance, then adjusted for historical knockout pedigree, overall squad quality and the likelihood of tighter knockout matches. (generated 2026-06-28)

Gemini 3.1 Pro — method

Predictions are primarily driven by goal difference and defensive stability from the group stage, weighted alongside historical knockout experience and squad depth to project winners and 90-minute scorelines. (generated 2026-06-28)

Gemini 3.5 Flash — method

Predictions are weighted heavily on recent 2026 group-stage form (points, goal difference, and goals scored), balanced against historical knockout-round pedigree and squad depth. (generated 2026-06-28)

Human 1.0 — method

Picks made after seeing the full group stage; no separate prediction made for extra time or penalties, just the 90-minute winner and score. (generated 2026-06-28)
