Side-by-side comparison of what ChatGPT, Gemini, Perplexity, Polymarket and the Onside model predict for this World Cup 2026 fixture.
Onside's per-fixture model pick
How ChatGPT, Gemini and Perplexity approach this fixture
None of the three publish per-fixture predictions during the tournament — they publish tournament-level picks. Here's their documented stance and how each typically reasons about a matchup like Uruguay vs Spain.
Favours high-FIFA-rank European teams; weights recent Nations League form heavily.
Leans toward technically-balanced sides; weights xG models.
Synthesizes consensus from multiple sources; tends toward the bookmaker favourite.
Real-money prediction market — sharp on short-term shifts, but slow to adjust on slow news.
ChatGPT, Gemini and Perplexity are general-purpose language models. They synthesise published articles to produce a tournament-level pick, then move on. Onside's model runs a 10,000-iteration Monte Carlo over the remaining schedule before every match, outputs a per-fixture probability split, and grades every call after full-time. That public accuracy record is the only honest benchmark of AI predictor performance during the tournament.
