This market tracks whether the United States will experience 1,250 or more tornadoes during 2026. On Polymarket, the probability of this outcome occurring stands at 70.0%. Resolution will be determined by the official tornado counts published by the National Centers for Environmental Information U.S. Tornadoes Time Series page, which releases monthly data according to a published schedule. Watch for the December 2026 tornado report release, scheduled before the January 10, 2027 resolution date, as this final monthly count will determine whether the annual total meets or exceeds the 1,250-tornado threshold.
This market will resolve according to the number of tornadoes recorded in the United States in 2026, based on the monthly counts 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 all months of 2026 will count. As of market creation, the December report is not yet scheduled, however the release schedule can be found here: 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.
Prediction market odds on Polymarket reflect real-time trader sentiment about 2026 tornado activity, which often diverges from traditional meteorological forecasts. While climate analysts typically rely on historical tornado data, atmospheric modeling, and seasonal patterns, prediction markets incorporate broader information including trader expectations about climate variability and extreme weather trends. The market-derived probabilities tend to be more dynamic and responsive to emerging data, whereas analyst forecasts are often published seasonally. Both sources offer valuable perspectives: markets capture collective intelligence, while expert forecasts provide detailed meteorological reasoning.

Resolution is determined by official tornado count data for the calendar year 2026, which establishes whether outcomes are met.

The final tornado count will be verified against authoritative meteorological records to settle all positions.
Several factors could shift market odds for How many Tornadoes in the US in 2026 before resolution. Major tornado outbreaks or active severe weather seasons would increase expectations for higher annual totals, moving prices downward if the market had favored below-average activity. Conversely, a quiet early season could strengthen confidence in lower tornado counts. Climate pattern shifts, including changes to jet stream behavior or sea surface temperatures, influence severe weather frequency. Updated seasonal forecasts from NOAA and other meteorological agencies provide key data points. Long-term climate trends and atmospheric oscillations like El Niño or La Niña also shape tornado activity expectations throughout the year.
