Investment Banker Offers Bay Area Home for AI Company Stock in Unusual Deal

An investment banker named Storm Duncan is trying something unconventional: he is offering to swap his Mill Valley home for shares in Anthropic, an artificial intelligence company. He created a LinkedIn company page to advertise the deal.

The 13-acre property in Mill Valley, California, which Duncan bought in 2019 for $4.75 million, would go to whoever trades him Anthropic shares. Duncan describes this as a way to rebalance his investments—he owns too much real estate and wants more exposure to AI companies.

How the Deal Would Work

Under Duncan's proposal, the person who gives him Anthropic shares would own the property. But there is a twist: they would keep 20% of any gains in the value of those shares during the period when they cannot sell them (called a lockup period). This sweetens the offer for someone who might worry about giving up the chance to benefit if the shares rise in value.

The idea addresses a real problem: people who work at or invested early in private companies like Anthropic often have stock worth substantial sums on paper, but cannot easily convert it to cash. A home swap allows them to diversify—move some of their wealth into real estate—while waiting for a chance to sell their shares.

This type of arrangement typically requires approval from the company whose shares are involved and may trigger tax complications that require careful legal structuring.

Why This is Happening Now

Anthropic and other leading AI companies have attracted enormous amounts of investment money in recent years, pushing their valuation into the billions of dollars. This means employees and early investors hold paper wealth—assets that look valuable but are hard to convert into actual money.

Meanwhile, Duncan moved away from the Bay Area during the pandemic to Miami, where remote work made it easier to live elsewhere. He still owns the Mill Valley property, which is currently occupied by what he describes as a high-profile venture capitalist. Many tech workers who moved during the pandemic faced the same situation: they wanted to diversify out of Bay Area real estate but found it difficult to sell property they no longer needed.

The Unusual Marketing Approach

Duncan is using LinkedIn, a professional network, to market the property instead of traditional real estate listing services. This targets a specific group—tech professionals with stock in private companies—rather than ordinary home buyers looking for a mortgage.

This breaks from the standard way homes are sold. It also signals something about how sophisticated the buyer needs to be. You cannot simply walk into a bank and get a mortgage if you are trading Anthropic shares; you need to understand stock, corporate law, and tax implications.

The Complications

Before this deal could happen, several obstacles stand in the way. Anthropic probably has rules that restrict how employees and investors can trade or transfer their shares. The company would likely need to approve any swap. There are also tax questions: depending on how the transaction is structured, both parties might owe taxes on the value exchanged.

The buyer would also need access to information about Anthropic's finances, management structure, and ownership that is typically only available to existing investors and kept confidential.

The broader context here is worth noting. This idea assumes both the AI company's value and Bay Area real estate values will keep rising. If either one falls significantly—which can happen in markets—whoever ends up holding both of these illiquid assets at the same time could face larger losses than if they were diversified across different types of investments.

What This Signals

This unusual transaction, whether it happens or not, points to a real challenge in modern tech finance. As AI companies become worth many billions of dollars, their employees and early investors accumulate significant wealth, but that wealth is locked up and difficult to access. Creative deals like this reflect the pressure to find ways around that problem.

Whether this specific transaction succeeds depends on finding someone who wants the Mill Valley home, understands private company equity well enough to evaluate Anthropic shares, and can navigate the legal structure. In a market where both AI stock and premium Bay Area real estate attract serious investor interest, matching buyer to seller may be possible. Executing the deal cleanly is the harder part.
