The United States Geological Survey (USGS) released an analysis stating that the probability of a magnitude 6.7 or greater earthquake affecting the San Francisco Bay Area within the next 30 years is 74%. [^1]

Local media outlets in the San Francisco Bay Area have publicly criticized the San Francisco Giants for running an advertisement for the Kalshi prediction market. [^2]

Geophysical projections from the report anticipate significant economic losses, water supply disruptions, and possible collapse of key transportation infrastructure in the event of a major earthquake. [^3]

Geophysicist Ned Field of the USGS explained that faults do not act alone; a rupture in one fault can trigger failures in others, raising the probability of significant seismic events in densely populated areas. [^4]

The USGS's UCERF3 seismic model and risk analyses identify the Hayward fault as the most imminent threat to the San Francisco Bay Area, with more than 30% probability of causing a large earthquake. [^5]

Media commentators argue that the advertisement promotes gambling-like activities to a fanbase that includes a significant number of minors. [^6]

The criticism from local media focuses on the unprecedented nature of the Giants featuring an ad for a prediction market platform. [^7]

The San Francisco Giants have not yet issued a public statement or response regarding the controversy over the Kalshi advertisement. [^8]
