**Important information: The resolution rules for the RAINM contract have been amended. Starting with the March 2026 iteration, markets will resolve based on the first NWS Daily Climate Report containing full-month data. The current February 2026 iteration is unaffected by this change and will continue to resolve via NOAA’s Climate Data Online Daily Summaries.
The primary resolution link will be a sum of NOAA’s Climate Data Online Daily Summaries of precipitation at the weather station specified. If no data is available, Kalshi will invoke its rules to settle the market using the NWS’ Monthly Climate Report; or if that is not available, the sum of precipitation in Daily Climate Reports.
