Bay Area Homeowner Proposes Trade of 13-Acre Mill Valley Estate for Anthropic Equity

Storm Duncan, a Miami-based investment banker, announced on LinkedIn that he would exchange his 13-acre Mill Valley estate for equity in Anthropic, the artificial-intelligence startup. The proposal is framed as a private transaction that would not require the buyer to sell existing Anthropic stock outright.

Duncan described his move as a “diversification play,” noting he feels under-concentrated in AI investments despite AI’s growing importance, while being over-concentrated in real estate. He believes a young Anthropic employee may face the opposite investment balance, prompting the exchange idea.

Storm Duncan, who lived in the Bay Area from 1996 until relocating to Florida during the COVID-19 pandemic, purchased the Mill Valley property in 2019 for $4.75 million. He previously worked as an investment banker and now markets the estate through a dedicated LinkedIn page.

The estate at 114 Inez Place includes a four-bedroom, five-bathroom ranch house, infinity pool, hot tub, putting green, and panoramic views of the Bay, Mount Tamalpais, and San Francisco. The parcel, together with an adjoining lot, totals roughly 13 acres; Duncan’s LinkedIn post cites 14 acres. Recent Anthropic funding rounds value the company at about $800 billion, guiding the expected share count.

Duncan explained that the deal would cover all closing costs and be structured as a private transaction, potentially offering tax advantages. He intends to retain 20 % of the upside value of the exchanged shares during any lockup period, allowing the buyer to keep their Anthropic holdings while acquiring the home.

The LinkedIn post describes the property as a “14-acre estate,” while public records and the article specify roughly 13 acres. The exact number of Anthropic shares to be exchanged remains undisclosed, with Duncan indicating negotiations will determine the count. No response from Anthropic or the unnamed high-profile VC occupant was provided.
