Strong El Niño conditions building in the tropical Pacific, combined with record global temperatures through mid-2026, drive the 76.5% market-implied probability that this year finishes as the warmest on record. Berkeley Earth’s August analysis placed the odds of a new annual record at 69%, citing year-to-date anomalies near 1.54 °C above pre-industrial levels and an unusually intense El Niño expected to add further warmth through year-end. Copernicus data show August 2026 tying July 2023 as the hottest month measured, with sea-surface temperatures also at record highs. NOAA reports place January–June 2026 as the third-warmest such period, while model consensus indicates the El Niño’s peak influence will arrive late in the year. Traders appear to weigh these factors against the slim chance that late-year cooling prevents 2026 from surpassing 2024.
