Recent global temperature observations position early May 2026 as the second-hottest period on record, driven by the long-term anthropogenic warming trend that continues to elevate baseline anomalies above pre-industrial levels. NOAA and NASA reanalysis data show daily averages for May 1–3 exceeding historical May norms by significant margins yet falling short of the absolute peaks set in prior years, owing to moderate ENSO-neutral conditions and the lack of intense heatwave amplification. Traders have adjusted implied probabilities accordingly, with the 66.5% consensus on second-hottest reflecting updated satellite and surface measurements that confirm this ranking while leaving limited room for a revised first-place outcome. Final verification of official records in coming weeks will determine whether any late adjustments shift these market-implied odds.

Note: If May 2026 is tied for first, second, or third hottest with another year, it will qualify for the bracket it ties with.
The primary resolution source for this market will be the figures found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "May" (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 June 30, 2026, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.
