This market will resolve based on the data for the Global Land-Ocean Temperature Index for May 2026 versus the data points available for all other Mays on record. 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.Preliminary ERA5 reanalysis from Copernicus shows May 1–13, 2026, global surface air temperatures tracking at +1.5°C above the 1991–2020 average—surpassing early-month anomalies from the record May 2024 (+1.55°C full-month) and second-place May 2025 (+1.33°C per Berkeley Earth)—driving trader consensus for a top-three finish, with 51.5% implied probability of first hottest amid persistent record sea surface temperatures (SSTs) near March 2026 peaks and ENSO-neutral conditions transitioning to El Niño (61% chance by July per NOAA CPC). Recent April 2026, joint third-warmest globally, reinforces the upward trajectory from anthropogenic warming trends, though model ensembles note variability from weather patterns in the month's remainder. Full-month data expected mid-June from NOAA and Copernicus will clarify rankings against historical baselines.
