How many 6.5 or above earthquakes June 15 - June 21?

On Polymarket, traders set prices by buying and selling outcome shares in an automated market maker system. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. Each outcome—ranging from zero major earthquakes to multiple events—has its own price between 0 and 100 cents, reflecting the probability traders assign to that scenario. As more capital flows into a particular outcome, its price rises and others fall, continuously rebalancing to reflect the latest consensus. Your position's value fluctuates with these price movements until the market resolves.

This market resolves around Jun 21, 2026, after the forecast period closes. The outcome is determined by counting verified major earthquakes—those measuring 6.5 magnitude or above—that occur during the specified week. Once the event window ends, the result is confirmed against credible public seismic data sources, and the winning outcome shares are paid out accordingly. Traders holding shares in the correct outcome bracket receive their proportional winnings.

Several factors can shift odds in this market before it resolves. A major earthquake or significant aftershock sequence during the forecast period would immediately increase prices for higher-outcome brackets. Conversely, a quiet week with no major seismic activity would push prices toward lower outcomes. Advance warnings from seismologists, volcanic activity, or unusual geological signals can also trigger trading. Additionally, real-time earthquake reports and updates from monitoring agencies throughout the week will drive continuous repricing as new data emerges.
