Polymarket
This market will resolve according to the total number of earthquakes with a magnitude of 5.5 or higher that occur anywhere on Earth between June 22, 2026, 12:00 AM ET, and June 28, 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 5.5 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 June 30, 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 markets aggregate real-time trader expectations, often diverging from traditional seismic analyst forecasts. While geologists and earthquake prediction services rely on historical data and fault-line analysis, this market reflects collective belief about actual earthquake frequency during the June 22–28 window. Traders incorporate breaking news, recent tremor activity, and expert commentary into their positions, creating a dynamic probability estimate. This market's odds represent a crowd-sourced alternative to static forecasts, updating continuously as new information surfaces and participants adjust their bets based on emerging geological signals.
On Polymarket, traders set the odds through an automated market maker mechanism, where buying or selling shares directly influences the price. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The current implied probability reflects the balance between bullish and bearish positions on earthquake frequency. Each share represents a claim on the outcome—either that five or fewer magnitude 5.5+ earthquakes will occur, or that more will happen. As traders buy or sell, the price adjusts to equilibrate supply and demand, with the displayed percentage representing the market's consensus likelihood of the leading outcome.
This market resolves around Jun 28, 2026, once the trading window closes and the week concludes. The outcome is determined by counting verified earthquakes of magnitude 5.5 or higher recorded worldwide during the specified period. Resolution relies on credible public seismic data from established geological monitoring agencies. Traders who correctly predicted whether the count would fall at or below five, or exceed that threshold, receive payouts proportional to their positions. The final tally is confirmed once sufficient time has passed for all seismic events to be catalogued and validated by authoritative sources.
Major tectonic activity, particularly along active fault lines in the Pacific Ring of Fire or other seismically volatile regions, would immediately shift odds. Real-time earthquake alerts from the USGS or international monitoring networks trigger rapid trader reactions as each magnitude 5.5+ event is recorded. Volcanic eruptions, aftershock sequences, or unusual subsurface activity can influence expectations about future tremors. Additionally, scientific publications or expert commentary on seismic forecasting may sway sentiment. As the resolution date approaches and the actual count becomes clearer, late-week tremors will have outsized impact on final pricing, with traders locking in positions based on the running tally.
