This market will resolve based on the data for the Global Land-Ocean Temperature Index for August 2026 versus the data points available for all other Augusts on record. Note: If August 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 "Aug" (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 September 30, 2026, 11:59:59 PM ET, a consensus of credible sources will be used to resolve this market.Recent official analyses confirm August 1, 2026, set a new Northern Hemisphere daily average temperature record at approximately 22.4–22.74°C (1.45°C above the 1979–2000 baseline), exceeding prior benchmarks amid an intensifying El Niño and lingering July heat that tied global and U.S. monthly records. This data from monitoring sources underpins the market’s 93.5% implied probability for the 1st-hottest outcome. Persistent warm anomalies across land and oceans, combined with model consensus on continued warming trends, reinforce trader consensus. Revisions in final datasets from agencies such as NOAA or Copernicus, or narrower resolution criteria focused solely on global rather than hemispheric averages, represent the main scenarios that could alter the ranking.
