A strengthening El Niño, with Niño-3.4 sea surface temperature anomalies already exceeding +2.5°C and forecasts pointing to a historic peak, is the dominant near-term driver lifting trader-implied probabilities toward the 1.30–1.34°C bin for September 2026 global surface temperature anomaly relative to 1850–1900. August 2026 set a joint record at 1.65°C above pre-industrial levels per ERA5, and ongoing equatorial Pacific warmth plus elevated global ocean heat content continue to support above-trend values, though model spread and the exact timing of peak El Niño impacts introduce uncertainty around the 1.3–1.5°C range. NOAA and ECMWF updates through late September will refine the final monthly figure.

An anomaly within a named bracket for September 2026 is necessary and sufficient to resolve this market immediately once the data becomes available, regardless of whether the figure for September 2026 is later revised.
The brackets are mutually exclusive and collectively exhaustive: each range is inclusive of both of its stated endpoints, and the reported anomaly (to the nearest 0.01ºC) falls within exactly one bracket.
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 "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 September 2026 is provided by NASA by November 1, 2026, 11:59 PM ET, this market will resolve to the lowest range bracket.
