Description

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.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All markets use the same resolution source (USGS) and timeframe (August 10 - August 16, 2026) to count earthquakes of magnitude 6.5 or higher.Primary resolution logic: United States Geological Survey (USGS) Earthquake Hazards Program

Core resolution logic:

  • Count all earthquakes with magnitude 6.5 or higher recorded by USGS between August 10, 2026, 12:00 AM ET and August 16, 2026, 11:59 PM ET
  • Markets resolve to 'Yes' for the exact count matching the question, or 'Yes' for the 'more than 5' market if count exceeds 5
  • If an earthquake occurs on the final day, markets may remain open for 24 hours to allow for magnitude revisions

Edge cases & clarifications:

  • Late Reporting: If a qualifying earthquake occurs but is not reported by USGS by August 19, 2026, markets may use alternative credible sources
  • Magnitude Revisions: If an earthquake's magnitude is revised upward to 6.5 or higher within 24 hours of occurrence, it counts toward the total
Timing: Markets resolve no earlier than August 17, 2026, and no later than August 19, 2026, based on USGS data availability and possible magnitude revisionsOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Polymarket

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.

Kalshi

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.

Frequently asked questions

The dashboard for the earthquake count market aggregates predictions across multiple venues, showing real-time odds and volume. It visualizes how traders on different platforms price the likelihood of specific seismic activity within the set timeframe. This unified view helps users compare sentiment and monitor shifts in expectations as new data emerges, reflecting the collective wisdom of the crowd on earthquake probabilities.

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.
