Key Points

  • A homeowner/investment banker in Mill Valley, California is offering a 13-acre property deal in exchange for Anthropic equity rather than cash or traditional financing.
  • The seller frames the arrangement as a “diversification play,” citing over-concentration in real estate and under-concentration in AI investments.
  • According to reporting, the transaction is intended to remain private and would not require the buyer to sell their Anthropic stock outright.
  • The LinkedIn description indicates the buyer would retain 20% of the upside value of the exchanged shares for the duration of the lockup period.
  • The property was reportedly purchased in 2019 for $4.75 million and is currently occupied by a “high profile VC,” though the VC was not identified.

Someone’s 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’d “like to exchange […] for Anthropic equity.”

The San Francisco Standard reports that Duncan described this as a “diversification play,” as he’s “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 deal specifics, but he said it would be a private transaction that doesn’t require the buyer to sell their stock outright. On LinkedIn, he also said the homebuyer would “continue to retain 20% of the upside value of the shares exchanged for the duration of the lockup period.”

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. It’s currently occupied by “a high profile VC,” he said, but he declined to identify the VC.
