Next is 1200–1249 at 5.4%. Only Polymarket lists this market, so there is no second price to compare.
Fair chance strips out each venue’s built-in margin (its prices add up to more than 100%), then blends the venues by how much has traded there, so the outcomes add up to 100%. Best Yes price is the cheapest ask across venues, and the payout is what a winning $100 stake returns before fees. Open a row for each venue’s contract name, bid and ask, and how closely their rules match.
Prices come from our regular polls of each venue, the oldest 1 min ago. Ages are as of when this page was built.

Live prediction market odds for "How many Tornadoes in the US in 2026?". 1250+ leads at 91.1%. Next is 1200–1249 at 5.4%. $86K has traded across 8 outcomes on Polymarket. The market is expected to resolve by Jan 11, 2027.
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. In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market. 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.
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
Venue prices refresh every few minutes, and the order book and live quotes stream continuously. Each venue’s card shows when we last observed it.
