Open Science & Tech Polymarket

2026 June 1st, 2nd, 3rd hottest on record?

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