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.Preliminary ERA5 reanalysis data through April 13 from Copernicus shows April 2026 global mean surface air temperature anomaly tracking toward 1.15–1.19ºC above pre-industrial (1850–1900) levels, aligning with the leading 41% market-implied probability as traders price in ENSO-neutral conditions following La Niña's fade. March's fourth-warmest ranking at 1.48ºC above pre-industrial drove earlier highs, but early April's moderated sea surface temperatures and weaker tropical forcing have tempered intensification potential, boosting adjacent 1.20–1.24ºC (24%) odds while downplaying extremes like >1.29ºC (7.6%). NOAA concurs with March at 1.31ºC above 1901–2000 baseline. Full-month resolution hinges on remaining weather patterns; expect Copernicus bulletin around May 10.
