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.

Prices come from our regular polls of each venue. Ages are as of when this page was built.

About this market

Live prediction market odds for "Where will a 6.0+ magnitude earthquake occur by end of October?". Japan leads at 34.5%. Next is Indonesia at 27%. $8K has traded across 7 outcomes on Polymarket. The market is expected to resolve by Nov 4, 2026.

This market resolves to "Yes" if the United States Geological Survey (USGS) reports an earthquake with a preferred magnitude of 6.0+ attributed to the listed country, with an origin time between October 1, 2026, 12:00 AM ET and October 31, 2026, 11:59 PM ET, by November 4, 2026, 12:00 AM ET. Otherwise, that market resolves "No". A qualifying earthquake must be counted for a country's market only if USGS attributes its location to that country in the event's location description, lists the earthquake with a preferred magnitude of 6.0 or higher, and lists it as occurring within the specified timeframe. Earthquakes without a preferred magnitude classification will not qualify. Revisions to a reported earthquake's underlying data, such as preferred magnitude and country attribution, will be considered until the end of the third calendar day after that earthquake's origin time (ET); revisions made after that time will not be considered. If a reported earthquake still qualifies at the end of its revision period, this market will resolve to "Yes" at that time, without remaining open until November 4, 2026, 12:00 AM ET. If it no longer qualifies at that time, this market will remain open until another qualifying earthquake is reported or the market's end date is reached, whichever comes first. If an earthquake with an origin time within a market's window has not yet appeared on the resolution source by November 4, 2026, 12:00 AM ET, this market end date may be extended for up to one week after November 4, 2026 and will resolve based on the preferred magnitude, country attribution, and timestamp of the event as of the end of its revision period (per the revision rules above), provided that revision period falls within the extension window. If the revision period would extend beyond the extension window, this market will resolve based on the data available at the end of the extension period. If the relevant data is not released by the end of the extension period, this market will resolve based on the data released up until that point. The resolution source for this event is the United States Geological Survey (USGS) Earthquake Hazards Program earthquake catalog (https://earthquake.usgs.gov/earthquakes/search/), and only data released by USGS will be considered, regardless of other sources. If the resolution source becomes temporarily unavailable, the market will remain open until it resumes; if it remains unavailable through November 4, 2026, 12:00 AM ET, this market will resolve to "No".

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.
