The consensus read on San Francisco mid-tier home prices has been a straightforward decline story for the past several years. The data now suggests the city may be writing a different chapter, and the reason is sitting in plain sight in the technology sector.
According to the seasonally adjusted Zillow Home Value Index (ZHVI), mid-tier home prices in San Francisco rose 1.5% in July from June, bringing the year-over-year change to a 11.6% gain. Not long ago, San Francisco sat near the top of the list of cities with the steepest price declines. The reversal, as reported by Wolf Street, began in the second half of last year, when mid-tier prices flipped from declining to surging. Even with that surge, mid-tier prices in July remained 6% below the all-time high reached in 2022.
AI Mania Filtering Down Into San Francisco Mid-Tier Home Prices
The driver, according to Wolf Street, is AI mania bleeding into the housing market. It started in the luxury segment, producing what has been described as a ‘mansion shortage.’ The effect has since filtered into the mid-tier band, the middle third of the market by price, where the ZHVI tracks single-family homes, condos, and co-ops.
Part of the structural backdrop: The Guardian reports that OpenAI and Anthropic, both headquartered in San Francisco, have filed to go public on the US stock market at valuations approaching $1 trillion. The wealth concentration that prospective listings of that scale could generate for workers and early investors in the city is not a trivial consideration when trying to explain why a housing market that was softening has suddenly reversed course. Wolf Street frames this as AI mania trickling down from luxury into the mid-tier band; the IPO pipeline gives that framing a concrete financial mechanism.
If AI mania lasts long enough, Wolf Street notes, mid-tier prices could set a new high before yearend for the first time since 2022. That conditional is worth holding onto: the spike is real, but the 6% gap to the prior all-time high still needs to be closed, and the conditions sustaining the demand are hardly guaranteed to persist.
The Broader Picture: 28 of 33 Cities Still Below Their Peaks
San Francisco’s reversal is the exception, not the rule. Across the 33 large and expensive cities tracked by Wolf Street using Zillow’s ZHVI, 28 remain below their respective prior peaks. Austin leads the declines at 27% below its June 2022 high, followed by Oakland at 25% and New Orleans at 19%. Year-over-year, prices fell in 24 of the 33 cities, with Austin again leading at -4.4%, Las Vegas at -3.1%, and Nashville at -3.0%.
Only two cities reached new all-time highs in the period: Chicago, up 4.5% year-over-year, and New York City, up 3.9%. Those are outliers in a dataset that is overwhelmingly pointing in one direction.
Boston is also worth noting separately. It joined the cities with declines from prior highs earlier this year, having peaked as recently as April 2025. Mid-tier prices there fell 0.5% in July from June, 1.4% year-over-year, and 2.3% from the April 2025 high.
The context behind the 2022 peaks matters. Prices in many of these cities had exploded between mid-2020 and mid-2022: Austin rose 62%, Phoenix 60%, Fort Worth 50%, Raleigh 49%, and Sacramento 39%. Wolf Street attributes those gains to Federal Reserve monetary policy during that period, which included large-scale purchases of Treasury securities and mortgage-backed securities using newly created money, pushing mortgage rates below 3% even as inflation was heading toward 9%. Buyers responded with what Wolf Street characterises as off-the-chart FOMO buying behaviour, bidding up prices to lock in those rates. Those buyers now hold below-3% mortgages on homes whose prices have since fallen, and Wolf Street notes they are fine as long as they stay put.
The ZHVI is a backward-looking measure drawing on millions of data points from public records, MLS, brokerages, local Realtor Associations, real-estate agents, and households, and includes off-market and for-sale-by-owner transactions.
For San Francisco specifically, the next test is whether the IPO-driven wealth effect is durable enough to push mid-tier prices through the remaining 6% gap to the 2022 all-time high, a threshold that will clarify whether this is a genuine rerating or an AI-fuelled overshoot waiting to correct.
