About this market
The strong trader consensus against a magnitude 9.0 or greater earthquake reflects the extreme rarity of these megathrust events, which demand simultaneous rupture across hundreds of kilometers on subduction zone faults. USGS data show only five confirmed M9+ quakes worldwide since 1900, with the most recent in 2011 and global rates averaging roughly one every 20–25 years; the 2025 Kamchatka event reached only 8.8. With just months remaining in the window, the short timeframe further lowers odds absent any current seismic indicators or model consensus pointing to imminent great earthquakes. A sudden clustering on high-strain segments like the Aleutians or Cascadia could alter this, though paleoseismic records indicate such outcomes remain statistically uncommon in brief intervals.
