Trader consensus on Polymarket prices a 57.5% implied probability for 2026 ranking as the second-hottest year on record and 36% for first, reflecting NOAA's April report of year-to-date January–April anomalies at +1.15°C above the 20th-century average—the fifth-warmest such period—coupled with sustained warmth in April (+1.12°C, fourth-warmest). The pivotal driver is NOAA's Climate Prediction Center update on May 14 forecasting an 82% chance of El Niño emergence in May–July, persisting through winter at 96% odds, which historically amplifies global surface air temperatures by elevating equatorial Pacific sea surface temperatures. Copernicus data corroborates April's joint third-warmest ranking (+0.52°C above 1991–2020), amid anthropogenic warming exceeding 1.4°C above pre-industrial levels, though El Niño intensity remains uncertain; upcoming May bulletins from NOAA and Copernicus will refine annual outlooks.

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.
