Trade: Another 7.0 or above earthquake by...?
Resolution criteria on PolyGram: This market will resolve to “Yes” if one or more earthquakes with a magnitude of 7.0 or higher occur anywhere on Earth between market creation and the listed date 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 the end of the month following resolution time or until the earthquake in question otherwise appears on the resolution source.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.

Market context
The market is pricing the probability that at least one earthquake measuring magnitude 7.0 or greater will occur anywhere on Earth between now and 31 May 2026. The current order book on Polymarket reflects a 100% implied probability, meaning traders are pricing this as virtually certain to occur within the settlement window.
Magnitude 7.0+ earthquakes occur with considerable regularity on a global basis. The USGS records approximately 15 earthquakes of this magnitude annually on average, though frequency varies year to year. Over the past decade, major seismic events have included the 2016 Kaikōura earthquake in New Zealand (7.8), the 2017 Puebla earthquake in Mexico (7.1), and the 2021 Fukushima earthquake in Japan (7.3). Given a 17-month settlement window and historical occurrence rates, the near-certainty pricing reflects straightforward statistical expectation rather than any exceptional seismic activity.
Traders monitoring this market should track USGS earthquake data releases, which are published in real time on the Earthquake Hazards Program website. The resolution mechanism depends entirely on USGS magnitude determinations, which occasionally undergo revision in the weeks following significant events as additional seismic data becomes available. The market allows for a one-month grace period following the settlement date to accommodate any reporting delays, meaning final resolution could extend into June 2026. No scheduled geological events or forecasts drive this market; it functions as a straightforward probabilistic bet on natural seismic activity rates.
Wikipedia Context

Another Earthquake!Another Earthquake! is the fourth studio album by American teen pop singer Aaron Carter, released on September 3, 2002. The album made its chart debut at number 18 on the US Billboard 200, but fell to number 41 in its second week. This album was much less successful than Oh Aaron, and would be Carter's third and final studio album with Jive Records.
How this market resolves
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
How to trade this market step by step
The mechanics for trading "Another 7.0 or above earthquake by...?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.

- Pick a side. Buy YES if you believe the event will happen; buy NO if you think it won't. The current YES price reflects the market's collective probability.
- Size your position. If you stake 100 USDC at 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% gross return. If NO resolves, your shares are worth $0.
- Set risk controls (optional). Stop-loss, take-profit, and limit-order types all supported. Use the trade ticket's slippage box to cap your maximum entry price.

Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
- CLOB
- Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
