2% — the median of 6 frontier models, resolving by 2027-10-31.

Answer

Gemini (Google): 4% — Leagues and players will resist any calendar expansion beyond the already strained 39-day window FIFA locked in. Domestic leagues and player unions like FIFPRO fiercely contested the 39-day footprint, making further lengthening virtually impossible. No modern World Cup has ever extended its overall calendar duration once the final schedule was ratified. Only unprecedented force majeure or severe disruption pushing the final past July 19, 2026, could trigger this outcome.

Answer

Claude (Anthropic): 4% — Fixed FIFA schedule June 11–July 19 is exactly 39 days; no mechanism exists to extend it. Dates are locked by FIFA with stadium/broadcast contracts set well in advance, leaving essentially no flexibility. Historical World Cups have never extended beyond their announced schedule due to unforeseen delays. Only a catastrophic disruption (pandemic, war, major incident) could force a postponement or extension, which is a low-probability tail risk.

Answer

GPT (OpenAI): 1% — FIFA’s published 11 June–19 July schedule is exactly 39 days, and a longer span would require an extraordinary disruption. The 104-match tournament ended on 19 July 2026 after beginning on 11 June, matching FIFA’s announced window. Past World Cups have not had their opening-to-final dates extended after play began; weather and logistics are handled within the schedule. Only a major force-majeure postponement moving the final beyond 19 July would change this assessment.

Answer

Grok (xAI): 0% — The 2026 tournament already finished on its published 39-day calendar. FIFA’s June 11–July 19 2026 window (39 inclusive days) was never altered by the time the final was played. No postponement, extra rest days or format change occurred after the 2022–2025 scheduling lock-in. A later start or later final would have been required to exceed 39 days; neither materialized.

Answer

DeepSeek (DeepSeek): 2% — FIFA's published calendar runs June 11 to July 19, 2026, exactly 39 days, so the statement is false unless the schedule is formally amended. FIFA has already published the official match schedule: June 11 to July 19, 2026, which is exactly 39 days inclusive, so the literal claim fails on the current calendar. Changing the window would require FIFA, its host associations, and broadcasters to renegotiate venues and TV slots, and no such revision has been announced as of October… Historically FIFA has never extended a World Cup beyond its published end date mid-cycle; the 2022 event ran 28 days and 2014 ran 31, so a 40-plus-day window would be…

Answer

Qwen (Alibaba): 2% — Scheduled June 11–July 19 is exactly 39 days; exceeding it would require an unprecedented disruption. June 11 to July 19 inclusive is precisely 39 calendar days, so the 'strictly exceeds' threshold is not met by the planned schedule. No FIFA World Cup has ever had its final postponed or the tournament extended beyond its announced window; the fixture list is locked months ahead. Only a force-majeure event (natural disaster, security crisis) could push the final past July 19, and even then FIFA would more likely relocate than extend.
