Recent developments show a developing El Niño event boosting baseline global temperatures alongside regional heatwaves across Europe and the US, keeping daily anomalies elevated but variable. July 1 saw notable European extremes, such as the Czech Republic's national record, while subsequent days featured shifting atmospheric patterns that moderated or redistributed heat. With all outcomes at equal 50% market-implied odds, trader sentiment reflects genuine uncertainty in distinguishing the precise ranking, driven by natural day-to-day fluctuations in global mean surface temperature from circulation patterns, land-sea contrasts, and reanalysis dataset margins (e.g., ERA5). Upcoming refined observational data from agencies like NOAA and Copernicus will clarify whether any of these days surpasses prior records set in 2023–2024.

Note: If July 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 "Jul" (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 July 2026 is provided by NASA by August 31, 2026, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.
