99% — the median of 6 frontier models, resolving by 2027-10-15.

Answer

Gemini (Google): 100% — The 2026 World Cup concluded in July 2026 with Mexico having already hosted multiple scheduled tournament matches. The 2026 FIFA World Cup took place between June 11 and July 19, 2026, meaning this is a retrospective fact as of late 2026. Mexico successfully hosted the opening match at Estadio Azteca on June 11, 2026, alongside other group and knockout fixtures. No catastrophic event or relocation occurred prior to the tournament, fulfilling the condition with certainty.

Answer

Claude (Anthropic): 98% — Hosting is contractually and logistically locked in; only a catastrophic disruption would stop it. Venues (Azteca, Akron, BBVA) and schedule are finalized by FIFA with Mexico hosting the opener. Co-hosting with US/Canada already confirmed via official match schedule released well before 2026. Only extreme scenarios like war, major natural disaster, or FIFA exclusion could change this, all low probability.

Answer

GPT (OpenAI): 99% — It turns almost entirely on Mexico retaining its already assigned host venues through the June–July 2026 tournament. FIFA's approved 2026 plan assigns 13 fixtures to Mexico City, Guadalajara, and Monterrey, including the opener at Estadio Azteca. Hosts virtually never lose all scheduled matches after venue selection; replacement would require an exceptional security, stadium, or political failure. Odds would fall sharply only if FIFA relocated Mexican fixtures before kickoff because venues could not meet operational or safety requirements.

Answer

Grok (xAI): 97% — whether any of Mexico’s 13 allocated 2026 WC matches actually kicked off in CDMX, GDL or MTY. FIFA locked the 13-match Mexico slate and three FIFA-certified stadiums in 2022; the tournament ran June–July 2026. No co-host has lost all allocated matches after the draw in the modern era; only war or pandemic would have forced a full relocation. A FIFA announcement moving every Mexico game after the June 2026 kickoff would flip the call, but none occurred.

Answer

DeepSeek (DeepSeek): 99% — The tournament already concluded; Mexican-hosted fixtures occurred in June-July 2026, making this a settled fact. All 13 Mexican fixtures (Azteca opener June 11, Guadalajara, Monterrey group and knockout games) were played as scheduled in June-July 2026. FIFA confirmed the venues after the 2022 inspection cycle; no credible cancellation threat ever emerged, unlike the pandemic-era Tokyo Games example. Base rate for completed World Cup host-city matches is ~100% across 22 tournaments; a stadium collapse or security catastrophe in spring 2026 would have been needed to…

Answer

Qwen (Alibaba): 99% — The 2026 World Cup has already concluded; Mexico's 13 scheduled matches were played as planned. The tournament ran June–July 2026 and is already over as of today's date, making this a settled fact rather than a forecast. Mexico hosted 13 matches across Estadio Azteca, Estadio Akron, and Estadio BBVA with no credible cancellation scenario having materialized. Only a definitional edge case (e.g., a match abandoned and replayed elsewhere) could flip this, which is vanishingly unlikely.
