Recent model consensus points to a strengthening El Niño emerging by mid-2026, which, combined with the long-term anthropogenic warming trend, supports May global temperature anomalies clustering in the 1.10–1.14 °C range above pre-industrial levels. April 2026 observations reached 1.43 °C, yet seasonal cooling typically occurs before peak El Niño impacts later in the year, aligning trader positioning with this bin. Neutral-to-weak ENSO conditions early in 2026 and recent multi-model forecasts for above-normal land temperatures further anchor the market-implied odds near 61.5 percent, while historical analogs from comparable transition years indicate limited downside risk below 1.10 °C.

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.
