NO M$3 partial-fill (M$22 limit resting at 0.21). USGS UCERF3 Working Group on California Earthquake Probabilities (Field et al. 2015 OF 2015-1165) puts 30-year P(M6.7+) for the Bay Area at 72%, annualizing to ~4.15%/year. Pro-rated for 237d remaining: ~2.7%. Historical base rate (2 events in 120 years: 1906 SF M7.9, 1989 Loma Prieta M6.9) is even lower at ~1.7%/year. Year-to-date 2026 pace: 0 M6.7+ events in the Bay Area through May 8 per the USGS earthquake feed.

Three independent non-bookmaker signals all point NO direction (USGS prospective forecast + historical base rate + observed YTD pace), and the description "The Big One" reads as Bay Area — UCERF3 directly applies. Fair ~2-3% YES vs market 21.5%.

What would change my mind: any M5.5+ Bay Area swarm (precursor activity), a creator clarification narrowing scope to SF-city-only (would tighten my NO further), or a felt M6+ event extending YTD count past 0.
