Trader mode: Actionable analysis for identifying opportunities and edge
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:
Prediction markets estimate a roughly 19 in 20 chance that the United States will see between 30 and 59 tornadoes in February 2026. This is the market's most confident forecast. Traders see it as very likely that the final count will fall within this middle range, avoiding either an extremely quiet or extremely active month.
The high confidence in a count of 30-59 tornadoes comes from historical weather patterns. February is typically a transitional month. It is not the peak of tornado season, which usually arrives in spring, but it is also not the quietest period. The average number of U.S. tornadoes for February over the last 20 years is about 44.
Recent climate trends also inform this prediction. Warmer winter temperatures, particularly in the Gulf of Mexico, can increase the moisture available for storm systems. This can lead to more frequent severe weather events even in late winter. Traders are likely weighing this potential for increased activity against the historical data, landing on the familiar average range as the safest bet.
The definitive report from the National Centers for Environmental Information (NCEI) is scheduled for release on March 9, 2026. This is the only date that matters for the final resolution of this market.
Before then, the market could shift based on real-time severe weather outbreaks during February itself. A major tornado outbreak in the first week could cause traders to move money toward the higher prediction brackets (60+ tornadoes). Conversely, an unusually stable and cold weather pattern across the central U.S. throughout the month might increase bets on the lower bracket (under 30 tornadoes).
Prediction markets are generally reliable for forecasting outcomes based on stable historical data and clear metrics, like an official government count. The NCEI dataset is the final authority, leaving no room for subjective interpretation.
However, weather remains inherently unpredictable in the short term. Markets can be slow to react to a sudden change in conditions. While the historical average is a strong guide, a single powerful storm system can produce dozens of tornadoes in a day, potentially pushing the total beyond the expected range. The market's 95% confidence reflects high certainty based on probabilities, but it is not a guarantee against a statistical outlier.
Prediction markets on Polymarket show high confidence in a typical February tornado count. The leading market, asking if 30 to 59 tornadoes will occur in the United States in February 2026, trades at 95 cents. This price indicates a 95% probability the final count falls within that range. With only 9 days until the official National Centers for Environmental Information (NCEI) report, the market views this outcome as nearly certain. Other buckets for lower or higher counts trade at minimal probabilities, showing a strong consensus around a mid-range result.
The pricing directly reflects historical climatology. According to NCEI data, the 1991-2020 average for U.S. tornadoes in February is approximately 29. The 30-59 bracket comfortably captures this average and the typical variability seen in most years. February is not a peak month for tornado activity, which usually surges in spring. Recent preliminary reports from storm prediction centers likely show no signs of an exceptionally active or quiet February 2026, allowing the market to anchor to the long-term norm. The high confidence suggests traders see no anomalous weather patterns that would push the count outside this standard deviation.
The odds are stable because the resolution source is a finalized government dataset, not real-time estimates. The critical risk is a significant data revision by the NCEI before its March 9, 2026, publication. Their process involves validating preliminary local storm reports, which can sometimes lead to downward adjustments in the final count. A revision placing the count at 29 tornadoes would cause the 30-59 market to resolve to "No," creating a major upset against the 95% confidence. However, such a revision large enough to drop below 30 is statistically rare for a monthly count already near the average. The market effectively bets this will not happen.

This prediction market focuses on forecasting the total number of tornadoes that will be recorded in the United States during the calendar year 2026. The outcome will be determined by the official final dataset published by the National Centers for Environmental Information (NCEI), a division of the National Oceanic and Atmospheric Administration (NOAA). The NCEI maintains a U.S. Tornadoes Time Series page that provides monthly counts, which are compiled from local National Weather Service offices and undergo a quality control process before finalization. This market is not about predicting the damage or intensity of tornadoes, but specifically the count of confirmed tornado events that meet the NCEI's reporting criteria. Interest in this metric stems from its use as a key indicator of severe weather activity. Meteorologists, climatologists, insurance companies, and emergency management agencies all monitor annual tornado counts to assess patterns, allocate resources, and model risk. The number can fluctuate significantly from year to year due to complex atmospheric conditions, making it a challenging but important variable to forecast. Recent years have seen notable volatility, with 2023 recording a near-record high of 1,423 tornadoes, while 2022 saw a below-average count of 1,141. This variability is driven by factors like sea surface temperatures, the position of the jet stream, and broader climate patterns such as El Niño and La Niña. Predicting the 2026 total involves analyzing these climatic drivers, historical trends, and advancements in detection technology that can influence reporting rates.
Systematic record-keeping of U.S. tornadoes by the federal government began in 1950, establishing the modern climatological baseline. The early decades of the record are considered less complete due to fewer observers and the absence of technologies like Doppler radar. A significant increase in reported tornadoes occurred after the national deployment of the NEXRAD Doppler radar network in the 1990s, which improved detection of weaker tornadoes, especially in rural areas. This creates a known discontinuity in the long-term record, where comparisons of raw counts before and after the mid-1990s must account for this "detection bias." The highest annual count on record is 1,817 tornadoes in 2004, a year characterized by a persistent weather pattern favorable for repeated severe thunderstorm development across the Plains and Midwest. Conversely, very low-activity years, such as 1987 with 656 tornadoes, often coincide with dominant high-pressure systems that suppress storm development. The past decade has shown high variability, with 2011 being a notorious year for violent tornadoes (including the Joplin and Tuscaloosa-Birmingham outbreaks) and a total count of 1,691. More recently, 2023's count of 1,423 was the fourth-highest on record, driven in part by an unusually active late winter and spring period. This historical volatility underscores the difficulty of annual prediction.
The annual tornado count is a primary metric for gauging the severity of a year's convective storm season. For the insurance and reinsurance industries, a higher count, particularly if it includes outbreaks in populated areas, directly correlates with increased financial losses. Years with major tornado disasters can strain regional economies and federal disaster relief programs. From a public safety perspective, emergency managers use climatological averages and forecasts to plan training exercises, review sheltering plans, and allocate response resources. A forecast for an above-average season prompts increased public messaging about preparedness. Scientifically, tracking the count over time contributes to the ongoing investigation into how climate change may be influencing severe thunderstorm environments. While a direct, simple trend in total tornado numbers is not clear, research suggests potential shifts in the geographic distribution and temporal concentration of tornado activity. This has long-term implications for land use, building codes, and community resilience in regions not historically considered part of "Tornado Alley."
As of late 2024, the climate system is in a neutral phase between El Niño and La Niña, according to NOAA's Climate Prediction Center. Forecasts suggest a transition to La Niña conditions is likely by the late summer or fall of 2025. The state of this oscillation through 2026 will be a major focus for seasonal forecasters, as La Niña winters and springs are often associated with more active severe weather seasons in the southern and central U.S. The final tornado count for 2024 is pending final quality control by the NCEI, but preliminary data indicates an active year. This recent activity will inform statistical models and analog years used by researchers to formulate early outlooks for 2026. The SPC has not yet issued any formal seasonal guidance for 2026.
The NCEI counts a tornado when there is confirmation from a National Weather Service damage survey that a rotating column of air made contact with the ground. The tornado must be a distinct event; multiple reports from the same tornado are consolidated into a single entry. The intensity, path length, or width do not affect whether it is counted, only its confirmation.
Annual variability is driven by large-scale weather and climate patterns that affect the availability of key ingredients for tornado formation: wind shear, instability, and moisture. Shifts in the jet stream, sea surface temperatures in the Pacific (ENSO), and other factors can create seasons that are persistently favorable or unfavorable for thunderstorm development across tornado-prone regions.
There is no clear trend in the total number of tornadoes observed annually since 1950. However, climate change is affecting the environments in which tornadoes form. Research indicates a possible increase in the frequency of days with high convective potential, a shift in the geographic distribution of tornado activity (with some increase in the Southeast and Midwest), and a longer tornado season.
Seasonal forecasts for tornado activity, issued by academic and some operational meteorologists, provide probabilistic outlooks for above or below-normal counts over large regions and multi-month periods. They have limited skill compared to day-to-day weather forecasts but are improving. They are best viewed as guidance on general risk levels, not precise predictions of exact numbers.
The NCEI typically publishes preliminary monthly data within weeks of the month's end. The final, quality-controlled data for a calendar year is usually completed and posted by the following March or April. The market on 2026 will resolve based on this final dataset once all months are officially reported.
