This market will resolve according to the numerical rank of how hot 2026 is when compared against all other years for which the Global Land-Ocean Temperature Index has data. 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.Trader consensus on Polymarket prices a 55.5% implied probability for 2026 ranking as the second-hottest year on record—behind 2024's record—and 35% for first, driven by NOAA's March 2026 outlook showing a 98.4% chance of top-5 placement amid emerging El Niño signals. After 2025 ranked second- or third-warmest across datasets like Copernicus and Berkeley Earth (0.01–0.13°C cooler than 2023/2024), early 2026 data—including January's fifth-warmest on record—combined with 62% odds of El Niño by June–August per NOAA's April update, signal intensified warming from equatorial Pacific heat release atop rising greenhouse gases. Model consensus projects anomalies of 1.35–1.53°C above pre-industrial levels, though inherent forecast uncertainty persists; watch May ENSO diagnostics and NOAA monthly reports for shifts.
