Preliminary counts from the National Weather Service Storm Prediction Center place August 2026 U.S. tornadoes near the long-term climatological average of roughly 81–85 events, with 86–96 confirmed or preliminary reports as of early September. This aligns with typical late-summer patterns of modest activity concentrated in the Upper Midwest, Great Lakes, and northern Plains, absent major outbreaks or multiple tropical cyclone landfalls that historically elevate totals. Trader consensus heavily favors the 80–99 bin because final National Centers for Environmental Information verification rarely deviates far from these preliminary figures once weak EF0 events are fully surveyed. The market-implied odds could shift only if post-season reanalysis adds or removes a substantial number of marginal reports, an uncommon outcome given current data quality.

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 September 9, 2026, at 5:01 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.
