San Francisco's housing market is undergoing a dramatic reversal. A city once synonymous with pandemic-era urban decline has become the hottest housing market in the United States, driven by the artificial intelligence boom. Wealthy employees of AI companies are competing so aggressively for move-in-ready homes that all-cash offers of $25 million are now considered insufficient in some segments of the market.

From empty offices to 50-bidder open houses

Three years ago, San Francisco looked entirely different. The city lost more than 60,000 residents between 2020 and 2022 as remote work surged during the pandemic. The median home sale price fell to $1.28 million by January 2023, down from a peak of $1.68 million the previous spring.

That slump is now over. The median home price has climbed 25% over the past twelve months, and real estate agent Paul Kitchen says certain listings have attracted as many as 50 offers.

“You have to laugh just because it is so ridiculous and so beyond the pale,” Kitchen said, describing situations in which top-end buyers offer $25 million in cash yet still fail to secure a home.

Why AI money is different

San Francisco has benefited from previous tech booms, but the AI boom stands apart because it concentrates wealth among a relatively small group. Most AI companies have not yet gone public, meaning the wealth remains in the hands of a narrow set of employees and investors. That marks a contrast with earlier cycles, when newly public companies spread equity gains across broad bases of shareholders and employees at once; here, much of the potential windfall is still locked in private hands until the anticipated listings take place.

The scale of the paper wealth involved is enormous. Current and former OpenAI employees could hold roughly $135 billion in post-tax equity if the company IPOs at its expected valuation, with Anthropic's employees holding approximately $63 billion more. Together, those two fortunes equal nearly 33% of the value of San Francisco's housing stock — a comparison that underscores how little of that wealth would need to flow into local real estate to move prices in a city where supply is famously constrained by geography and decades of zoning limits.

Both OpenAI and Anthropic plan to list on the stock market. Each has leased about 1 million square feet of office space in San Francisco over the past two years while bringing employees back to the office — a shift that has begun to reverse the pandemic-era hollowing out of downtown, where office vacancy hit 34.4% in late 2025.

Renters and lower-income buyers priced out

The pressure extends beyond the luxury segment. Young, highly paid tech workers are paying $10,000 a month in rent, and some rental listings draw hundreds of inquiries within hours. Average rent in San Francisco has risen by more than $1,000 in a year to roughly $4,600, making the city the most expensive rental market in the country, just ahead of New York.

Households on ordinary incomes face even steeper barriers. According to a May 2026 analysis from Realtor.com and the National Association of Realtors, only 2.1% of March listings were affordable to a household earning $75,000 a year — equivalent to just 2,475 homes. For teachers, nurses, and other workers the city depends on, the shrinking pool of affordable listings adds to long-running concerns about middle-class flight that surfaced during the pandemic population losses.

A tale of two tech hubs

The AI boom has not lifted every tech hub. Seattle has seen home prices decline 3.6% to $809,479, weighed down by layoffs at Amazon and Microsoft.

By contrast, San Francisco's July median sale price rose 6% year over year to $1.6 million, while active listings fell 18.4% — the sharpest inventory drop in the nation.

In the first quarter, the flow of home movers from San Francisco to Seattle fell to 369 people, down from more than 5,100 in 2021. “AI is reorganizing the tech labor market, with San Francisco and Seattle representing two sides of that transition,” said Chen Zhao, head of economics research at Redfin.

What comes next for San Francisco?

City officials are moving to expand housing supply. In December 2025, San Francisco passed the Family Zoning Plan into law, opening more neighborhoods to denser housing. The legislation also enables reforms that would help convert vacant office space — which carried a 34.4% vacancy rate in late 2025 — into homes, addressing a commercial-real-estate glut left behind by remote work even as housing demand surges.

Whether new construction arrives fast enough to make a difference remains an open question, as demand continues to outpace the number of homes for sale. The anticipated OpenAI and Anthropic public listings loom as a further test of how much of the sector's paper wealth converts into purchasing power in the years ahead.
