Will there be an at least 8 magnitude earthquake in California before 2027?
🗂 Part of event: Will there be an 8 magnitude earthquake in California before 2027? →💡 What the odds say
The market puts this at about a 6% chance — very unlikely.
No money — just record your call and see if you were right. Yes is at 6% right now.
The market heavily discounts a magnitude 8+ California quake before 2027, but recent global seismic activity and a moderate Northern California tremor keep the risk non-zero, though historical rarity and short remaining window anchor the low odds.
📊 Base rate: Since 1900, California has experienced only one magnitude 8+ earthquake (the 1906 San Francisco quake), giving a roughly 0.8% annual probability based on historical frequency.
What's driving it
- • A 5.6 magnitude earthquake shook Northern California on June 24, 2026 (ABC10), reminding traders of ongoing seismic activity but far below the 8.0 threshold.
- • Four powerful earthquakes worldwide occurred within hours on June 25, 2026 (Gizmodo), raising public attention to global seismicity but not directly increasing California's specific risk.
- • A 7.8 quake in the Philippines on June 8, 2026 (KCRA) and deadly Venezuela quakes on June 24-25 (CTV News, CBC) highlight that large quakes are occurring elsewhere, but no clear catalyst has shifted odds for California specifically.
- • The market odds have remained stable near 6% for months, indicating no new scientific or geological data has emerged to change the baseline probability.
- • yes
- • no

How it resolves
Settled by Kalshi, a CFTC-regulated US exchange, against the official source named in each contract (e.g. a government release or election certification), with an Outcome Review Committee as a backstop for disputes.
Resolution criteria
If there is at least an earthquake of 8 magnitude with an epicenter in California or its territorial waters before Jan 1, 2027, then the market resolves to Yes.
ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.
