How research worksResolution rules
This market will resolve to the value reported by the Global Land-Ocean Temperature Index for September 2025 when it is released. Otherwise, this market will resolve to "No". An anomaly of a named bracket for September 2025 is necessary and sufficient to resolve this market to "Yes" immediately once the data becomes available, regardless of whether the figure for September 2025 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 "Sep" in the row "2025" (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 September 2025 is provided by NASA by December 1, 2025, 11:59 PM ET, this market will resolve "Yes".
