Recent observational data from NASA and NOAA place global temperatures near 1.19 °C above the 1951–1980 baseline for 2025, reflecting the long-term anthropogenic trend superimposed on ENSO-neutral conditions that persisted through early 2026. With subsurface Pacific warming now evident and an 82 % probability of El Niño onset by May–July per the Climate Prediction Center, May 2026 surface anomalies are expected to remain anchored near recent monthly values in the 1.10–1.14 °C range. Model ensembles show limited disagreement for this month, as the developing warm phase has not yet produced the strongest teleconnections that typically elevate later-year temperatures.

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.
