Recent observations and model runs confirm August 2026 surface temperatures are tracking well above 1.5 °C relative to the 1850–1900 baseline, driven by a developing strong El Niño, record-breaking extra-polar sea-surface temperatures (peaking near 21.1 °C in late August per Copernicus data), and the underlying anthropogenic warming trend. Daily global means have repeatedly exceeded prior August benchmarks, with land and ocean anomalies both elevated and the month projected near 1.6 °C. The 99.5 % market-implied probability for >1.29 °C reflects this robust observational consensus and limited remaining forecast uncertainty. Only an unprecedented late-month cooling event or substantial downward revision in final datasets would realistically alter the outcome.

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.
