A Duboce Triangle listing is letting buyers swap private AI shares for a Victorian-era home, reflecting the strange new world where tech equity doubles as currency.
A 119-year-old home in San Francisco’s Duboce Triangle neighborhood is now for sale at $2.995 million. The seller will accept Anthropic or OpenAI stock instead of actual dollars.
The listing at 160 Noe St., a 2,495-square-foot home built in 1907, went live in late May 2026 on Zillow. It represents one of the first known instances in the city where private shares from the two most prominent AI companies can be swapped directly for residential property.
When your stock portfolio becomes a house key #
This isn’t the first time it’s happened. Investment banker Storm Duncan listed his Mill Valley estate, roughly 4,400 square feet, in late April or early May 2026. His asking price wasn’t denominated in dollars at all. He wanted offers exclusively in Anthropic shares. That property was valued at approximately $8 million.
The 160 Noe St. listing is a bit more flexible, accepting either Anthropic or OpenAI stock alongside traditional payment.
The numbers behind the madness #
Anthropic’s most recent Series H funding round valued the company at $965 billion post-money. That number surpasses OpenAI’s $852 billion valuation.
San Francisco’s median home price has risen from around $1.4 million to over $1.6 million since February 2026, driven in part by the wealth generated from the AI boom.
The fine print is where it gets complicated #
Private shares from companies like Anthropic and OpenAI typically come with transfer restrictions. These are contractual limitations that prevent shareholders from selling or transferring their equity without company approval. Most private tech firms maintain a right of first refusal, meaning the company itself can block a transfer or demand the chance to buy the shares back first. The IRS treats stock-for-property transactions as taxable events. Both parties would need to establish a fair market value for the shares at the time of the transaction, which is inherently tricky for private companies that don’t have a public market price.
Some industry observers have noted that listings like these may function partly as marketing tactics. Advertising that you’ll accept AI stock generates headlines and attracts a very specific pool of wealthy, tech-connected buyers. Whether the transaction actually closes in stock or converts to a traditional cash deal at the last minute is almost beside the point.
Secondary markets for private tech shares have been growing for years, with platforms facilitating billions in pre-IPO equity trades.
