NextFin News - In the hyper-competitive San Francisco real estate market, where the median home price has climbed past $2 million, cash is no longer the ultimate leverage. A new breed of sellers is now bypassing the U.S. dollar entirely, opting instead for equity in the world’s most valuable private artificial intelligence companies. In late May 2026, a 119-year-old Victorian home in the Duboce Triangle neighborhood hit the market for $2.995 million with a listing that explicitly states: "Anthropic or OpenAI stock will be considered as payments."
The trend is not limited to city Victorians. Storm Duncan, founder of the tech investment bank Ignatious and a veteran banker who has worked with Google and Uber, is offering his four-bedroom estate in Mill Valley—purchased for $4.5 million in 2019—in exchange for pre-IPO Anthropic shares. Duncan’s move highlights a growing desperation among investors to secure a stake in AI’s "Big Two" before they potentially go public later this year. For employees at these firms, who are often "paper rich" but cash poor due to the illiquidity of private shares, the arrangement offers a rare path to homeownership without waiting for a secondary market sale or an IPO.
Storm Duncan (Ignatious) has long maintained a bullish stance on the transformative power of AI infrastructure, often positioning himself at the forefront of unconventional tech-financing deals. His willingness to trade a multi-million dollar physical asset for private equity reflects a high-conviction bet that AI valuations will continue to outpace the appreciation of Bay Area land. However, this strategy remains a niche phenomenon. While high-profile, these "stock-for-shack" deals represent a fraction of the broader market and do not reflect a consensus among San Francisco’s real estate or financial institutions, many of whom remain wary of the legal and tax complexities involved.
The mechanics of these transactions are fraught with friction. Most private tech firms maintain a "right of first refusal," allowing the company to block any share transfer or buy back the stock itself. Furthermore, establishing a fair market value for private shares is notoriously difficult in the absence of a public exchange. Sellers like Duncan are essentially acting as their own valuation experts, betting that the future upside of Anthropic—which is reportedly preparing for a public debut—outweighs the stability of a Marin County compound. For the buyer, the trade triggers immediate tax implications, as the IRS generally treats the exchange of stock for property as a sale of the shares at their current fair market value.
Skeptics point to the inherent volatility of the AI sector as a reason for caution. While the AI boom has catapulted San Francisco’s median home price up by double digits over the last year, the concentration of wealth in just two or three private entities creates a fragile ecosystem. If the anticipated IPOs of 2026 fail to meet the lofty valuations currently traded on secondary markets, sellers who traded physical deeds for digital certificates may find themselves holding devalued paper. For now, the "Anthropic premium" continues to distort local pricing, as at least seven San Francisco homes sold for more than $1 million over their asking price last month alone, driven by a buyer pool that views AI equity as the only currency that matters.
