Strong El Niño conditions, with Niño-3.4 anomalies exceeding +2.5°C and still intensifying, combined with record global sea-surface temperatures peaking at 21.1°C in late August, have driven August 2026 surface temperatures to levels aligning closely with the market's dominant 1.38–1.41°C bin. Long-term anthropogenic warming provides the baseline elevation, while the developing El Niño supplies the additional boost evident in Copernicus ERA5 and other reanalyses showing this August among the warmest on record. Trader consensus at 92.5% implied probability reflects these verified observational trends and model consensus on ENSO-driven warmth. Final dataset revisions or differences across agencies could still shift the precise anomaly within narrow bounds, though a move outside the leading range appears unlikely given the strength of current signals.

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