This market will resolve to "Yes" if the data for the Global Land-Ocean Temperature Index for August 2025 shows an increase greater than that of any prior August when it is released. Otherwise, this market will resolve to "No".

At the point the data for August 2025 is first released, it will be compared to all previous data points for August, and if the data for August 2025 is higher than all previous data points, this market will resolve to "Yes".

Note: If 2025 August is tied for highest with another year, it will NOT suffice to resolve this market to "Yes" - it must be higher.

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 2025 is provided by NASA by October 1, 2025, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.

2025 August hottest on record?

This market will resolve according to the numerical rank of how hot 2026 is when compared against all other years for which the Global Land-Ocean Temperature Index has data.

Years will be ranked in descending order, starting with the hottest as number 1, the second hottest as number 2, etc.

If 2026 ties with any other year, it will resolve according to the place the year it ties with occupies.

This market will resolve immediately once the specified data becomes available, regardless of whether the figure for the relevant years is later revised.

The primary resolution source for this market will be the figure found in the table titled "Land-Ocean Temperature Index (C)" under the column "No_Smoothing" in the row "2026" (https://data.giss.nasa.gov/gistemp/graphs/graph_data/Global_Mean_Estimates_based_on_Land_and_Ocean_Data/graph.txt). If NASA's "Global Temperature Index" is rendered permanently unavailable, other information from NASA may be used. If no information for 2026 is provided by NASA by March 1, 2027, 11:59 PM ET, this market will resolve based on a consensus of credible reporting.

This market may not resolve to "No" until the December 2026 report is issued. Once the December 2026 report is issued, any revisions to previously released CPI figures will not be counted toward this market's resolution. If the CPI report for December 2026 is not issued by January 31, 2027, 11:59 PM ET, this market will resolve based on CPI figures which have already been made available by the BLS.

Note: the resolution source for this market will be the official monthly BLS CPI news release which reports inflation over 12 month periods to only one decimal point (e.g. 2.9%). Thus, this is the level of precision that will be used when resolving the market.
