Mill Valley Home Offered in Exchange for Anthropic Equity

other · 2026-04-26

In Mill Valley, California, a 13-acre estate is available in exchange for equity in the AI firm Anthropic. Storm Duncan, an investment banker and the property's owner, shared this unique offer on LinkedIn, labeling it a "diversification play" aimed at balancing his investments in real estate and AI. Duncan acquired the property for $4.75 million in 2019 and believes it would attract a young employee from Anthropic who lacks real estate exposure. The arrangement would be private, allowing the buyer to keep 20% of the shares' upside during the lockup period. Currently, a prominent venture capitalist occupies the estate. Duncan, who relocated to Miami during the pandemic, invites interested individuals to contact him via email for more details.
