This market will resolve based on the data for the Global Land-Ocean Temperature Index for April 2026 versus the data points available for all other Aprils on record. Note: If April 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 "Apr" (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 April 2026 is provided by NASA by May 31, 2026, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.This market will resolve based on the data for the Global Land-Ocean Temperature Index for April 2026 versus the data points available for all other Aprils on record.

Tight odds in this market stem from the razor-thin margin separating recent record Aprils—2024's global surface air temperature anomaly of +0.86°C above the 1991-2020 baseline edging out 2023 (+0.79°C), 2020 (+0.74°C), and others—against projections of continued anthropogenic warming at 0.2°C per decade per CMIP6 models. Trader consensus hovers near even for top-three finishes due to high uncertainty in 2026's ENSO phase; a potential El Niño recurrence could push anomalies toward 1st (needing ~+0.9°C), while La Niña risks 4th or lower. Recent 2024 year-to-date heat, despite emerging La Niña cooling, reinforces the elevated baseline, with no major volcanic cooling expected to differentiate outcomes.
