This market will resolve according to the value reported by the Global Land-Ocean Temperature Index for April 2026 when it is released. An anomaly within a named bracket for April 2026 is necessary and sufficient to resolve this market immediately once the data becomes available, regardless of whether the figure for April 2026 is later revised. The primary resolution source for this market will be the figure found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "Apr" in the row "2026" (https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt). If NASA’s “Global Temperature Index” is rendered permanently unavailable, other information from NASA may be used. If no information for April 2026 is provided by NASA by June 1, 2026, 11:59 PM ET, this market will resolve to the lowest range bracket.Trader consensus on Polymarket centers on a global surface air temperature anomaly of 1.15–1.24ºC for April 2026 versus pre-industrial levels (1850–1900), with 1.20–1.24ºC leading at 31.5% implied probability, driven by March 2026's fourth-warmest ranking at 1.48ºC (Copernicus ERA5 data released April 10) amid near-record sea surface temperatures. Differentiating the tight 1.15–1.19ºC (26%) and 1.20–1.24ºC bins are ENSO-neutral conditions favored through June (80% NOAA/CPC probability), potentially cooling from March peaks, versus early April westerly wind anomalies signaling possible El Niño emergence that could sustain heat. Forecast models highlight uncertainty from Atlantic warmth and stratospheric influences; watch mid-May Copernicus bulletin for final ERA5 confirmation.
