Recent observational data from agencies including Copernicus and NOAA indicate May 2026 global surface temperatures are tracking within the 1.10–1.14 °C anomaly range above the 1850–1900 baseline, consistent with the multi-year warming trend and elevated ocean heat content. Market-implied odds reflect trader assessment of model consensus projecting limited deviation this month amid neutral-to-weak La Niña influences, following April’s 1.43 °C reading. Key resolution criteria center on official monthly averages; revised final datasets or stronger-than-expected regional cooling could shift outcomes, though historical analogs and current monitoring suggest narrow probability for such shifts before June reporting.

An anomaly within a named bracket for May 2026 is necessary and sufficient to resolve this market immediately once the data becomes available, regardless of whether the figure for May 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 "May" 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 May 2026 is provided by NASA by July 1, 2026, 11:59 PM ET, this market will resolve to the lowest range bracket.
