Recent record ocean warmth and the rapid intensification of a strong El Niño event represent the main drivers behind trader positioning near 1.38–1.45°C for the August 2026 global temperature anomaly. Sea surface temperatures reached a new daily high of 21.1°C in late August, with Niño-3.4 anomalies exceeding +2°C amid forecasts of a potentially historic event peaking later in the year. This adds to the background warming trend, though model spread and timing of peak El Niño impacts introduce meaningful uncertainty for the precise August value. Official monitoring from NOAA and Copernicus highlights ongoing ocean heat content increases, with traders weighing these factors against historical analogs for monthly anomalies around 1.4°C.

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.
