The AI Effect on Silicon Valley Real Estate: Bigger Than Google, Facebook and Apple Combined?
by
In 2019 we asked whether the “Uber effect” would be as large as the “Facebook effect” on Bay Area home prices. The 2026 version of that question is a lot bigger. OpenAI and Anthropic, both based in San Francisco, are valued at $852 billion and $965 billion in their latest funding rounds. Together that’s about 14 times what Apple, Google and Facebook were worth combined on the days they went public. So is the AI effect going to be bigger than the Google, Facebook and Apple effects combined? We’re the Property Nerds, so we ran the numbers on two years of house sales in 12 Silicon Valley cities and San Francisco.
The short answer
- In dollars, it already is. OpenAI’s $852 billion (March 31, 2026) and Anthropic’s $965 billion (May 28, 2026) add up to about $1.82 trillion, against about $129 billion for Apple (1980), Google (2004) and Facebook (2012) at their IPO prices. As public companies, today’s giants are still bigger: Apple alone was worth about $5 trillion at the October 30, 2026 close.
- In house prices, San Francisco moved most. The median San Francisco house sold for $1.95M in the last 12 months, up 21% from $1.61M the year before. The typical one closed 18.7% over asking, up from 8.2%, and 173 sold for $5M or more, up from 88.
- The Peninsula is next. Menlo Park (+9.1%), Mountain View (+7.6%), Redwood City (+7.2%) and Palo Alto (+4.7%) rose.
- Most of the South Bay slipped. Median house prices in Sunnyvale, Cupertino, Santa Clara, San Jose and Los Gatos were 2% to 3.3% lower, and across the 12 Silicon Valley cities, sales of $3M+ houses slipped from 2,017 to 1,929.

City by city, north to south
Houses only, the last 12 months (October 28, 2025 to October 27, 2026) against the 12 months before. The headquarters column is where each company is based, not where its people live.
| City | Headquarters | Median, year before | Median, last 12 months | Change | Typical sale vs. asking | Houses sold |
|---|---|---|---|---|---|---|
| San Francisco | OpenAI, Anthropic | $1.61M | $1.95M | +21.0% | 18.7% over | 2,287 |
| Redwood City | — | $2.2M | $2.36M | +7.2% | 4.3% over | 470 |
| Menlo Park | Meta | $3.3M | $3.6M | +9.1% | 2.4% over | 261 |
| Palo Alto | — | $3.82M | $4M | +4.7% | 5.7% over | 363 |
| Los Altos & Los Altos Hills | — | $5.05M | $5.1M | +1.0% | 2.7% over | 350 |
| Mountain View | $2.74M | $2.95M | +7.6% | 7.0% over | 213 | |
| Sunnyvale | — | $2.7M | $2.63M | −2.6% | 7.4% over | 466 |
| Cupertino | Apple | $3.45M | $3.33M | −3.3% | 3.5% over | 190 |
| Santa Clara | NVIDIA | $2.02M | $1.97M | −2.6% | 5.1% over | 381 |
| Campbell | — | $2.13M | $2.17M | +1.7% | 3.0% over | 160 |
| San Jose | — | $1.68M | $1.65M | −2.0% | 1.6% over | 3,467 |
| Saratoga | — | $4.2M | $4.28M | +2.0% | 0.9% over | 200 |
| Los Gatos & Monte Sereno | — | $2.92M | $2.84M | −3.0% | 0.6% under | 362 |
Percent changes are figured from the exact medians, so some differ slightly from the rounded prices shown.
San Francisco also had the largest jump in houses selling over asking of the 13: 81% of its houses sold over list price, up from 71%.
What happened after Facebook went public, and what’s different now
Facebook went public on May 18, 2012, at about $104 billion. From 2012 to 2013, the median house price rose in every one of these 12 Silicon Valley cities, by 11.2% in Saratoga up to 26.9% in San Jose. Menlo Park, Facebook’s home since late 2011, rose 14.3%, the second-smallest gain of the 12. That was a region-wide rebound from the housing bust as much as a Facebook effect.
This time the pattern is different. The gains are concentrated: strongest in San Francisco, solid along the Peninsula, and mostly absent in the South Bay so far. The top of the market moved most. San Francisco’s $5M+ house sales nearly doubled, and across the 12 Silicon Valley cities, $5M+ sales rose from 472 to 515 while $3M+ sales dipped.
Why the AI effect could get bigger from here
- Paper becomes down payments only when people can sell. OpenAI let current and former employees sell about $7 billion of shares in August 2026, as reported, after about $6.6 billion in October 2025.
- Two IPOs are lining up. Anthropic filed publicly with the SEC on October 26, 2026 to list on the Nasdaq. OpenAI filed confidentially in June 2026, as reported. After an IPO, employees commonly wait out a lockup, often about six months, before they can sell, so any effect on housing can come in waves rather than all at once.
- It’s bigger than two companies. The AI build-out runs through the chipmakers and platforms based here: NVIDIA in Santa Clara, Apple in Cupertino, Google in Mountain View and Meta in Menlo Park.
- The 2019 caution still holds. A company going public doesn’t guarantee a payout for every employee, private-round prices aren’t cash, and valuations can fall as fast as they rise.
If you’re selling
- In San Francisco and on the Peninsula, price from the last 90 days. When the median San Francisco house rose 21% in a year, a sale from last fall can understate what your home is worth now.
- In the South Bay, price from your street, not the headlines. San Francisco’s run hasn’t reached San Jose, Santa Clara or Sunnyvale in these numbers. See selling a home in San Jose and every city we cover.
- Read stock-funded offers closely. Ask what the down payment is: cash, vested shares, or proceeds from a sale that hasn’t closed yet. An offer that depends on a pending share sale carries timing risk, and the contract terms should cover it.
If you’re buying with equity
- Lenders treat vested shares, RSUs and sale proceeds differently, and selling shares can be a taxable event. Our RSU and company stock guide walks through it, and your tax advisor has the final word.
- Expect competition at the top end in San Francisco and on the Peninsula. Buying with tech equity covers the plan, and home prices near 18 tech headquarters shows what a commute costs.
How we counted
Closed sales of houses (MLS property type “single family home”) from October 28, 2025 to October 27, 2026, against October 28, 2024 to October 27, 2025, in 12 Silicon Valley cities and San Francisco, reported to the MLS and read through the IDX feeds that power our home search, with repeat records from different feeds removed and one record per sale with a usable living area and map position, the same rules as our city price posts. Los Altos includes Los Altos Hills; Los Gatos includes Monte Sereno. “Typical sale vs. asking” is the median of sale price against list price. The 2012–2013 comparison uses calendar years and leaves out San Francisco, where our records are complete only from 2022. Valuations are the post-money valuations OpenAI (March 31, 2026) and Anthropic (May 28, 2026) announced; IPO values are at the offer price: Apple on December 12, 1980 (about $1.8 billion), Google on August 19, 2004 (about $23 billion) and Facebook on May 18, 2012 (about $104 billion), in the dollars of the day. Past sales aren’t a forecast or the value of any one home, and nothing here is investment advice.
