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 implies a 45% chance that 2026 ranks second-hottest on record and 29.5% for first, driven by NOAA's latest forecasts showing a 62% probability of El Niño emergence by June-August 2026, which historically amplifies global surface temperatures amid ongoing anthropogenic warming. With 2024 holding the record as the warmest year and 2025 ranking second or third across datasets from NASA, NOAA, and Copernicus Climate Change Service, early 2026 data supports this positioning: January and February were the fifth-warmest on record despite lingering La Niña effects. Model ensembles project annual anomalies around 1.4°C above pre-industrial levels, though inherent uncertainties in ENSO evolution and ocean heat uptake could shift outcomes; watch April IRI and NOAA updates for refinements.
