Home prices during the AI boom have surged far faster in the Bay Area’s luxury zip codes than its non luxury zip codes—a split not seen before the launch of GPT-3.5 or in other major U.S. metros.

Luxury zip codes in the San Francisco Bay Area saw a 13.4% average jump in home prices in the two years following the launch of ChatGPT. That’s a significantly larger jump than any other price segment in the Bay Area and is more than double the 6.3% average increase in the segment immediately below luxury. The most affordable Bay Area zip codes saw home prices fall.
