Will there be 8 or fewer earthquakes of magnitude 7.0 or higher worldwide by June 30?

What this market is about

The question is whether the final tally of worldwide earthquakes at magnitude 7.0+ will come in at 8 or less by the end of June 30, 2026. The resolution source is the USGS Earthquake Hazards Program’s significant earthquakes page, so the market is tied to how that official catalog records qualifying events within the time window. If an earthquake occurs near the deadline but has not yet appeared on the USGS source, the market can stay open until July 7, 2026, or until that event is reflected there.

Why the market exists

There is real uncertainty because large earthquakes are rare but not evenly spaced, and the number that happen in a six- to seven-month span can vary a lot. Readers may care because this is a clean, publicly verifiable seismic count with a firm cutoff date, and the outcome hinges on whether the final total stays at or below the threshold in the title. The market is essentially pricing disagreement about whether one or more additional magnitude 7.0+ quakes will be recorded before the deadline.

What can move the price

Any newly reported magnitude 7.0 or stronger earthquake anywhere in the world would be the clearest event-specific driver, especially if it appears on the USGS significant earthquakes list. A quake that happens close to June 30 could matter even more if it is large enough to push the count above 8, since the market explicitly allows extra time for delayed USGS posting. Smaller earthquakes, aftershocks below 7.0, or events that do not meet the threshold should not affect the outcome.
