This market tracks the likelihood of at least one earthquake with a magnitude of 9.0 or higher occurring anywhere in the world before the end of 2026. Currently, the consensus probability—aggregated from Polymarket and Opinion—is 25.0% that such an earthquake will occur. The USGS Earthquake Hazards Program (https://earthquake.usgs.gov/earthquakes/browse/significant.php#sigdef) serves as the definitive source for resolution. Keep an eye on seismic activity as we approach February 1, 2027, which is the current resolution date estimate for this market.
This market will resolve to “Yes” if 1 or more earthquakes with a magnitude of 9.0 or higher occur anywhere on Earth between December 8, 2025 12:00 PM ET, and December 31, 2026, 11:59PM ET. Otherwise, this market will resolve to “No”. The resolution source for this market is the United States Geological Survey (USGS) Earthquake Hazards Program (https://earthquake.usgs.gov/earthquakes/browse/significant.php#sigdef). 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 January 31, 2027, 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. After a qualifying earthquake is registered, this market will remain open for 24 hours to account for any revisions to its recorded magnitude. After 24 hours, this market will resolve according to the latest provided data.

Prediction market odds, like those found in this market, often reflect a 'wisdom of the crowd' that can differ from individual expert opinions. While seismologists provide valuable insights into earthquake probabilities based on geological data, this market incorporates a broader range of information and perspectives. It’s not uncommon to see discrepancies between prediction market probabilities and traditional forecasts, as traders may weigh factors not fully captured in scientific models. However, studies have shown prediction markets can sometimes outperform traditional forecasting methods, especially when dealing with complex and uncertain events.
Prices on Polymarket and Opinion can diverge due to several factors. Polymarket and Opinion can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Each platform has a different user base with varying risk appetites and information sets, leading to differing valuations. Trading volume also plays a role; higher volume on one platform can lead to more efficient price discovery. Furthermore, the specific mechanisms for trading and market making on each platform can influence price formation. Currently, Polymarket currently favors a lower probability of a 9.0+ earthquake at 3.4%, while Opinion leans toward a higher probability at 25.0%.
This market resolves around Feb 1, 2027, with the outcome confirmed once the event is verifiable from credible public reporting. The determination will be based on data from established seismological agencies regarding the magnitude and timing of any earthquakes that occur. The outcome of this market is whether a magnitude 9.0 or greater earthquake has occurred at any location globally before the resolution date. No specific source is used to determine the outcome, but rather a consensus from established and reliable sources.
Several events could significantly influence the price of this market. Major aftershocks following a large earthquake in a known subduction zone could increase perceived risk. New scientific research suggesting increased seismic activity in a particular region could also shift trader sentiment. Conversely, a period of prolonged seismic quiet, with no significant earthquakes, might lower the perceived probability. Geopolitical events impacting monitoring capabilities or disaster preparedness could also play a role. Any credible reports from geological surveys or changes in established risk assessments would likely move this market.
