Category 1 or above 96.5%
Next is Category 2 or above at 88%. The venues differ most on Category 5 or above (Polymarket 5%, Kalshi 7%), a 2.0-point gap.
Consensus blends each venue’s last price, weighted by how much has traded there. 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 2 min ago. Ages are as of when this page was built.





Do not treat this price difference as directly comparable.
No arbitrage: the best bid elsewhere is 2¢, at or below the cheapest ask of 7¢.

Live prediction market odds for "How strong will Vance be?". Category 1 or above leads at 96.5%. Next is Category 2 or above at 88%. $4K has traded across 9 outcomes on Kalshi and Polymarket. The market is expected to resolve by Nov 5, 2026.
This market will resolve according to the peak intensity of Vance (NHC designation EP222026). Peak intensity means the highest Saffir-Simpson Hurricane Wind Scale category assigned to Vance in any Tropical Cyclone Public Advisory issued for the storm. The category is stated in the advisory and is determined by maximum sustained wind speed (1-minute average): Category 1 is 74 to 95 mph, Category 2 is 96 to 110 mph, Category 3 is 111 to 129 mph, Category 4 is 130 to 156 mph, and Category 5 is 157 mph or greater. Each category includes both of its stated bounds, so every possible peak wind speed falls in exactly one category. If Vance never reaches Category 1 strength, "Category 1 or weaker" will resolve to "Yes". Wind speeds will be used exactly as published, without rounding. Maximum sustained winds are reported in increments of 5 mph. Post-storm best track data and the Tropical Cyclone Report for Vance will not be considered for resolution. Advisories issued by any agency other than the National Hurricane Center will not be considered for resolution. This market will resolve once Vance dissipates. If Vance has not dissipated by November 4, 2026, 11:59 PM ET, or if the advisory data needed to determine its peak intensity has not been published by that time, this market will remain open for up to 2 calendar days (ET) after that date; it will then resolve based on the finalized advisory data published up to that point. If the data is still unavailable at the end of that period, or publication has been discontinued, this market will resolve according to the highest category assigned to Vance in any advisory published up to that point. In case of obvious data integrity issues (i.e., erroneous data), the market may remain open until the end of the third calendar day (ET) after such data is first released to allow for corrections; this applies only to clerical or similar errors, not to the issuing center differing from other sources. A reanalysis or reclassification of Vance's intensity published after Vance dissipates will not change the resolution of this market. Revisions published before Vance dissipates will be considered; revisions published after it dissipates will not be considered for resolution. The primary resolution source for this market will be the Tropical Cyclone Public Advisories issued for Vance by the National Hurricane Center (https://www.nhc.noaa.gov/), specifically the category and the maximum sustained wind speed stated in the advisory.
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.
