Common questions about WC 2026 winner predictions
Who will win the World Cup 2026?›
Our 10,000-run Monte Carlo simulator currently favours France at 12.6%, followed by Spain (11.7%), England (11.1%), Argentina (9.3%), and Portugal (7.7%). These probabilities refresh hourly and shift as group-stage results land. No single team is over 15% — that's how open the tournament is.
How does Onside predict the World Cup winner?›
We run the entire tournament from current state forward 10,000 times. Each match samples from our opponent-rating model (FIFA rank + PL squad footprint + host advantage + confederation strength). Completed matches use the real result with certainty. Aggregating across runs gives each team a champion probability. Full methodology at /world-cup-2026/methodology.
Are the World Cup 2026 winner predictions accurate?›
Pre-tournament we target a top-3 calibration window — meaning the actual champion should be among our top-3-rated teams roughly 50% of the time historically. The board sharpens dramatically as the tournament progresses; by the SF round, only 2 matches remain to sample.
Can I share these predictions?›
Yes — every top-8 card has X/Reddit/WhatsApp share buttons that pre-fill the tweet with the team and probability. Or share this page directly for the full board.
How often does the World Cup winner prediction update?›
Hourly via ISR/dynamic rendering. Once group-stage matches start playing, every result locks into the simulator and ripples through the champion probabilities. The favourite can shift by 2-3% per matchday during the knockout rounds.
