A Mill Valley homeowner is offering to exchange his 13-acre property for equity in AI startup Anthropic. The seller says the unusual structure is a diversification play and would allow the buyer to retain some upside during the lockup period.

To buy this Bay Area home, you’ll need Anthropic equity

Someone is offering an unusual deal for a 13-acre property in Mill Valley, just north of South Francisco.

Homeowner and investment banker Storm Duncan has created a LinkedIn page for the home, which he said he would "like to exchange […] for Anthropic equity."

A Diversification Play

The San Francisco Standard reports that Duncan described the proposal as a "diversification play." He said he is "under-concentrated in AI investments relative to the importance of AI in the future, and over-concentrated in real estate," while a young Anthropic employee might be "in the exact opposite scenario."

Duncan is asking potential buyers to email him to discuss the specifics of the deal. He said it would be a private transaction that does not require the buyer to sell their stock outright.

On LinkedIn, Duncan added that the homebuyer would "continue to retain 20% of the upside value of the shares exchanged for the duration of the lockup period."

Property Background

Duncan, who described himself as a longtime Bay Area resident who moved to Miami during the pandemic, bought the property in 2019 for $4.75 million.

He said the home is currently occupied by "a high profile VC," but declined to identify the venture capitalist.
