About This Market

This market resolves to the number shown in the "BROKEN" column of NOAA's Daily Weather Records tool when filtered to all-time record highs for August 2026. Tied records do not count. The tool is located at https://www.ncdc.noaa.gov/cdo-web/datatools/records. The Timescale will be All-Time Records", "Highest Max Temperature" for Parameter, and the month of August 2026 for the Date Range. The number in the "BROKEN" column is the resolution value. Only records broken in the United States will resolve this market. Full documentation of the GHCN-Daily dataset is available at https://www.ncei.noaa.gov/products/land-based-station/global-historical-climatology-network-daily. The market resolves on September 15, 2026, based on the value shown in the tool at that time. This reading is final. Any corrections, revisions, or additional data that NOAA processes after September 15 will not affect the outcome. September 15 snapshot may not include all August records due to reporting lag but will govern the resolution regardless.
