Odds by venue

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.

About this market

Live prediction market odds for "Will a hurricane make landfall in Hawaii before 2027?". Yes leads at 5.5%. Next is 2026 at 2%. $82K has traded across 2 outcomes on Polymarket and Kalshi. The market is expected to resolve by Dec 31, 2026.

This market will resolve to "Yes" if any storm makes landfall in the State of Hawaii at Category 1 strength or higher, as reported in official Central Pacific Hurricane Center advisories (https://www.nhc.noaa.gov/cphc/), between market creation and December 31, 2026, 11:59:59 PM ET. Otherwise, this market will resolve to "No". A landfall counts toward this determination only if it occurs within this window; the time of the physical landfall governs, not the time any confirming advisory is issued. A hurricane is a tropical cyclone with maximum sustained winds of 74 mph or greater (Category 1 or higher on the Saffir-Simpson Hurricane Wind Scale), as described at https://www.nhc.noaa.gov/aboutsshws.php, and a hurricane landfall is said to occur when the hurricane's surface center intersects with the coastline, as described at https://www.nhc.noaa.gov/aboutgloss.shtml#LANDFALL. A storm must hold hurricane strength (Category 1 or higher on the Saffir-Simpson scale) at the moment its surface center intersects the coastline for that landfall to qualify. "Hawaii" means the entire State of Hawaii as recognized under U.S. law, including the main Hawaiian Islands (Hawaiʻi, Maui, Oʻahu, Kauaʻi, Molokaʻi, Lānaʻi, Niʻihau, and Kahoʻolawe) and the Northwestern Hawaiian Islands (including Midway Atoll and the Papahānaumokuākea Marine National Monument). The wind speed at the moment of landfall will be determined from the CPHC advisory or Special Advisory in effect at the time closest to the reported landfall time; where no advisory covers that exact moment, the most recent advisory issued prior to landfall governs. This market may resolve based on the initial CPHC advisory reporting a qualifying landfall regardless of any later advisory, retraction, best-track revision, or reanalysis that revises that storm's intensity downward at the time of landfall. However, if a subsequent advisory or correction identifies a qualifying landfall that was not reflected in initial reporting, this market will resolve to "Yes" based on that correction.

Questions

What does the consensus price mean?

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%.

How is the payout worked out?

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.

Why do the venues show different prices?

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.

Is a price gap an arbitrage?

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.

How fresh are these prices?

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.
