Summary
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.
