This event group tracks the number of earthquakes with a magnitude of 6.5 or higher occurring worldwide between August 10 and August 16, 2026. The markets resolve based on data from the USGS Earthquake Hazards Program.
This market will resolve according to the total number of earthquakes with a magnitude of 6.5 or higher that occur anywhere on Earth between August 10, 2026, 12:00 AM ET, and August 16, 2026, 11:59 PM ET. The resolution source for this market is the United States Geological Survey (USGS) Earthquake Hazards Program, with the minimum magnitude set to 6.5 and the date parameters set to the relevant dates for this market's timeframe (https://earthquake.usgs.gov/earthquakes/search/). If an earthquake of substantial size has occurred within this market's timeframe but not yet appeared on the resolution source, this market may remain open until August 19, 2026, 11:59 PM ET, or until the earthquake in question otherwise appears on the resolution source. If such an earthquake has not appeared on the resolution source by that date, another credible resolution source will be used. This market may not resolve until the timeframe of this market has concluded. If a qualifying earthquake has been recorded on the final day, this market may remain open for 24 hours to allow for revisions to the recorded magnitude. After 24 hours, this market will resolve according to the latest provided data.
The event evaluates multiple thresholds of earthquake magnitudes, all measured using the Moment Magnitude Scale, occurring anywhere worldwide before September 1, 2026. Each market corresponds to a specific magnitude threshold, ranging from 6.8 to 7.5 or higher. If an earthquake meets or exceeds any of these thresholds within the specified period, the respective market resolves positively. The structure allows for varying degrees of seismic intensity to be assessed independently, providing a layered approach to predicting geological events. All outcomes depend solely on the occurrence of a qualifying earthquake before the deadline, with no other conditions affecting resolution.
On Polymarket, odds reflect crowd-sourced probabilities that can diverge from traditional analyst reports, which may rely on historical patterns and geological assessments. Prediction markets often price in real-time sentiment and emerging data points not yet reflected in formal forecasts. While analysts may offer detailed risk evaluations, this market lets traders bet on immediate shifts, sometimes showing higher or lower expected probabilities than institutional outlooks.
Differences in user bases and market design can lead to varied pricing. Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. On Polymarket, liquidity and participation levels may amplify rapid price changes reacting to news, while Kalshi could show steadier values due to its own user dynamics. The way each platform structures its contracts also influences how traders interpret and place bets on seismic risk.
This market resolves around Sep 1, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Seismic monitoring agencies will provide the official record of earthquakes meeting the magnitude and timing criteria, and the market will close based on that verified data. No subjective judgment is involved—only whether the recorded events match the parameters.
Seismic activity reports, geological surveys, and news of tectonic movements can all shift expectations. Any significant tremor near the magnitude threshold may cause rapid re-pricing. Additionally, broader geopolitical or environmental developments affecting monitoring capabilities—or even large-scale fear-driven sentiment—could influence trader behavior and push odds in either direction before the market closes.
