How many 6.5 or above earthquakes August 3 - August 9?

Platform comparison

Market context

A **magnitude 6.5-plus earthquake** can clear this market with a single event, but the real question is whether the USGS count lands at one, two or more before the August 9 cut-off. The crowd-implied 95% YES suggests traders are already pricing in at least one qualifying quake during the week, and that is consistent with how frequently large tremors appear on a global basis: 2026 has already produced multiple M6.5+ events, including a M7.8 in the Philippines and a M6.5 in Mexico, with the Mindanao sequence alone generating repeated strong aftershocks.[4][12][15]

Recent activity has been concentrated in the western Pacific and the Americas, which matters because the week’s outcome can turn on one offshore rupture or a late-reviewed event rather than a steady stream of large quakes. USGS’s significant-earthquake listings and weekly world map are the most relevant references for confirmation, and the market rules also allow for a delay if a substantial quake has occurred but has not yet appeared on the resolution source.[1][8][13]

For traders, the key catalyst is not a calendar event but the post-event reporting cycle: large earthquakes can be reviewed, upgraded, or added after the fact, and the market notes that it may stay open until August 12 if a qualifying quake has not yet surfaced on the USGS record.[7] That makes the final hours of the window especially sensitive to any late-arriving USGS entries, particularly from remote offshore zones where initial magnitude estimates are often revised after more seismic data is processed.[1][9]

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.
