Trader consensus on Polymarket strongly favors 2026 ranking as the second-hottest year on record (57.5% implied probability), with a substantial chance of claiming first (36.5%), driven by NOAA's April 9 ENSO Diagnostic Discussion projecting a 61% likelihood of El Niño emerging in May-July and persisting through year-end. This follows a warm start to 2026, where Copernicus ERA5 data shows January through April as the fourth- to fifth-warmest respective months globally, amid fading La Niña influences. Against baselines of 2024 as the hottest year (NASA GISS) and 2025 as third-warmest (NOAA), anthropogenic warming trends plus potential El Niño amplification position top-two outcomes, though model uncertainty in event strength tempers odds below 90%. Upcoming NOAA and Copernicus monthly bulletins will refine full-year projections.

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.
