Where will 2026 rank among the hottest years on record?

Traders currently price "1" at 67% for "Where will 2026 rank among the hottest years on record?". Over the past 24 hours that probability moved down 2.0 points. Full distribution: 1 67%, 2 31%, 3 2%, 6 or lower 1%. The market has traded $3.3M in total volume and resolves Dec 31, 2026. Recent strengthening of a major El Niño event in the tropical Pacific, with Niño-3.4 anomalies exceeding +2°C and forecasts for a very strong phase through winter 2026-27, is the dominant catalyst elevating 2026's implied odds for first- or second-warmest ranking. This overlays the long-term anthropogenic warming trend, as 2026's January-June period already ranks third-warmest and June second-warmest per NOAA data. Model consensus and recent analyses project the annual average likely exceeding prior records or placing immediately behind 2024, though forecast uncertainty in peak El Niño intensity and late-year variability could still shift outcomes toward third place. Traders weigh these dynamics against baseline climatology, where El Niño years historically amplify global temperature anomalies by 0.1-0.2°C above the trend.
