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 places April 2026's global surface air temperature anomaly at approximately 1.15–1.19°C above the 1850–1900 pre-industrial baseline, driving trader consensus with 50.5% implied probability on that bin, closely trailed by 1.10–1.14°C at 38.5%. This positioning reflects second-warmest April SSTs on record at 21.08°C (per Copernicus Marine Service, trailing only April 2024), fueled by persistently elevated equatorial Pacific temperatures amid ENSO-neutral conditions through April–June (80% NOAA probability). Absent La Niña cooling or volcanic influences, greenhouse gas forcing sustains high baselines, though final Copernicus bulletin expected early May could refine measurements amid inherent reanalysis uncertainties. Historical analogs from recent record Aprils underscore the tight clustering around 1.1–1.2°C.
