France's summer of 2026 has delivered a blockbuster run of record-shattering heat that has locked in overwhelming trader consensus around the "Yes" outcome. Multiple prolonged heatwaves produced 52 days of official conditions—the highest total on record—while July posted the hottest monthly average ever measured and the full June-August national mean is tracking roughly 1°C above the long-standing 2003 benchmark. Stations across the country logged unprecedented numbers of 40°C+ readings, with many all-time highs falling in a single intense June spell. With summer nearly complete and final data already reflecting this dominance, only an extraordinary late-August reversal or definitional technicality could still alter the result.

This market will resolve to "Yes" if Météo-France's official seasonal climate report, the "Bilan climatique de l'été 2026," states that meteorological summer 2026 (1 June to 31 August 2026) is the warmest summer in France in the Météo-France record, which begins in 1900, as measured by the national average temperature ("température moyenne") calculated by Météo-France. Otherwise, this market will resolve to "No". For the avoidance of doubt, summer 2026 must be the single warmest summer on record. If Météo-France reports summer 2026 as tied for warmest with a prior year, or ranks it anything other than first, this market resolves to "No".
The primary resolution source is the "Bilan climatique de l'été 2026" published by Météo-France, the French national meteorological service which is typically published in the first week of September.
If the seasonal report has not been published by September 30, 2026, this market may alternatively resolve using the equivalent statement on the Météo-France seasonal summaries page (https://meteofrance.fr/actualite/publications/2026-les-bilans-climatiques) or in an official Météo-France press release covering the summer 2026 season.
If Météo-France has not published a summer 2026 climate summary by December 31, 2026, this market may resolve based on credible reporting (e.g., Reuters, AFP, France 24) confirming whether summer 2026 is the warmest summer on record.France's summer of 2026 has delivered a blockbuster run of record-shattering heat that has locked in overwhelming trader consensus around the "Yes" outcome.
