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 July 14, 2026, 12:00 AM ET, and July 19, 2026, 11:59 PM ET. 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 July 21, 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.

Prediction market odds reflect decentralized trader sentiment rather than formal seismological forecasts. While geologists and seismic institutes publish probabilistic hazard assessments based on historical data and fault-line analysis, this market aggregates real-money bets from participants worldwide. The two approaches differ fundamentally: analysts rely on geological models and historical patterns, whereas traders incorporate breaking news, recent tremors, and market dynamics. Comparing the two reveals whether the crowd's financial incentive to predict accurately aligns with or diverges from expert consensus on earthquake frequency.
On Polymarket, this market is priced through an automated market maker that converts trader activity into real-time odds. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Shares representing each outcome trade continuously, and the current price of a share reflects the implied probability that outcome will occur. As traders buy or sell shares based on new information or conviction, the price adjusts automatically. The top outcome currently reflects market consensus, and the spread between bid and ask prices indicates how confident and liquid the market is at any given moment.
This market resolves around Jul 19, 2026, after the seven-day observation window closes. The outcome is determined by counting verified major earthquakes—those measuring magnitude 6.5 or above on the Richter scale—that occur worldwide during the specified period. Once the event window ends, the final count is confirmed against credible public seismic data sources. Whichever outcome matches the actual number of qualifying earthquakes is declared correct, and traders holding winning shares receive their payout based on the final odds at resolution.
Several factors can shift odds significantly before Jul 19, 2026. A major earthquake or aftershock sequence during the prediction window will immediately trigger repricing as traders update their forecasts. Seismic alerts, volcanic activity, or unusual geological readings may also influence sentiment. News of tectonic stress or expert warnings about specific fault lines could prompt buying or selling. Additionally, early results within the window—for example, if two magnitude 6.5+ events occur in the first few days—will anchor expectations and reshape probabilities for the remaining days. Real-time seismic monitoring data and media coverage are the primary catalysts.
