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 May 8, 2026, at 5:00 PM GMT+1 or 11:00 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.Trader consensus on Polymarket, with 170–199 tornadoes leading at 28% implied probability, reflects a preliminary confirmed count of 23 tornadoes through April 11 from National Weather Service surveys—below the roughly 60 needed for an average-paced month matching the 1991–2020 climatological norm of 182. Early-April outbreaks on the 2nd–4th contributed most, featuring multicell clusters and weak EF0–EF1 spin-ups amid favorable wind shear and Gulf moisture. Differentiating higher bins like 260–289 (20.5%) are Storm Prediction Center slight-risk outlooks for April 11–13 across southern Plains to Midwest, where elevated convective available potential energy (CAPE) and veering winds could spawn supercell tornadoes; lower bins hinge on pattern weakening post-weekend, with daily SPC updates key to resolution amid typical confirmation lags in final NOAA tallies.
