This market will resolve according to the number of tornadoes recorded in the United States during the specified month, based on the monthly count published on the National Centers for Environmental Information U.S. Tornadoes Time Series page (see: https://www.ncei.noaa.gov/access/monitoring/tornadoes/time-series). Only tornadoes appearing in the final NCEI dataset for that month will count. As of market creation, the relevant report is scheduled to be released on June 8, 2026, at 5:01 PM GMT+1 or 11:01 AM ET (Release schedule: https://www.ncei.noaa.gov/access/monitoring/dyk/monthly-releases). The market will resolve based on the first relevant tornado count published on the NCEI tornado time-series page after this scheduled release time. If the value published after this scheduled release time is labeled preliminary, it will still determine resolution, and the market will resolve independently of any subsequent revisions, corrections, or retroactive adjustments. The market will not resolve based on any preliminary values published before the scheduled release time. If no data is published by the scheduled release time, or if the NCEI website is temporarily unavailable, this market will remain open until that data is made available. If the relevant data is not made available by the date of the next scheduled publication ET, this market will resolve based on available data for the most recent prior month. If the NCEI website becomes permanently unavailable, this market will resolve using another credible source.Recent severe weather outbreaks, including an EF3-rated tornado in Mississippi during the May 6–7 event and additional confirmed twisters across Oklahoma, Texas, and Arkansas, have kept early-month counts near or slightly above seasonal norms. The National Weather Service and Storm Prediction Center note that May historically averages about 265 tornadoes nationwide, with activity shifting northward into the Plains and Midwest as the jet stream migrates. Current model guidance indicates elevated convective available potential energy and wind shear across the central U.S. through the coming week, though ridge-trough patterns could limit further outbreaks. With roughly half the month remaining, trader sentiment clusters around the 200–259 range because revised preliminary counts and late-May forecast updates could easily shift the final total above or below the long-term baseline.
