The developing El Niño in the tropical Pacific, with multi-model ensembles showing rapid warming toward +1.5°C Niño 3.4 indices by May–July, is the dominant factor behind trader consensus for a 1.10–1.14°C May 2026 global temperature anomaly. Early May observations already record record-high Northern Hemisphere surface temperatures 1.13°C above the 1979–2000 baseline, consistent with the shift from neutral to El Niño conditions and the long-term warming trend that kept 2025 at 1.19°C annually. Official seasonal outlooks from the WMO and NOAA reinforce above-normal land and ocean temperatures across most regions, while May’s position early in the event limits the monthly boost relative to later peaks. Updated forecast runs and observational data releases through June will provide the next clear signals for any revision in these market-implied probabilities.

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.
