The emergence of El Niño conditions in the tropical Pacific, confirmed by recent NOAA advisories and expected to intensify into a strong or very strong event by late 2026, stands as the dominant driver behind trader consensus favoring a second-place ranking for 2026 global temperatures. This ENSO phase adds substantial warmth atop the long-term anthropogenic trend, following 2024 as the record holder and 2025 as third-warmest, with model ensembles and early-year observations aligning 2026 near or just behind 2024 levels. Market-implied odds of 66% for second and 25% for first reflect this positioning, tempered by uncertainty in peak intensity, while lower probabilities for ranks beyond third acknowledge the near-certainty of top-five status per agency outlooks. Updated forecasts through summer will further refine these probabilities as the event evolves.

Years will be ranked in descending order, starting with the hottest as number 1, the second hottest as number 2, etc.
If 2026 ties with any other year, it will resolve according to the place the year it ties with occupies.
This market will resolve immediately once the specified data becomes available, regardless of whether the figure for the relevant years is later revised.
The primary resolution source for this market will be the figure found in the table titled "Land-Ocean Temperature Index (C)" under the column "No_Smoothing" in the row "2026" (https://data.giss.nasa.gov/gistemp/graphs/graph_data/Global_Mean_Estimates_based_on_Land_and_Ocean_Data/graph.txt). If NASA's "Global Temperature Index" is rendered permanently unavailable, other information from NASA may be used. If no information for 2026 is provided by NASA by March 1, 2027, 11:59 PM ET, this market will resolve based on a consensus of credible reporting.
