A luxury townhouse in Williamsburg, Brooklyn just hit the market for $5.99 million. Nothing unusual there, except for the payment options: the seller will take cash, sure, but they’d also happily accept vested Anthropic shares or Bitcoin.
The property at 3 Wythe Lane spans 4,470 square feet and features four bedrooms, five bathrooms, and a finished basement with 12-foot ceilings. But the real story isn’t the square footage. It’s what this listing says about how wealth is being stored, transferred, and increasingly, spent in 2026.
When your stock portfolio becomes a down payment
The Brooklyn listing didn’t emerge in a vacuum. It follows a pattern that started gaining traction on the West Coast earlier this year, where sellers in affluent neighborhoods began targeting a very specific buyer: someone sitting on a mountain of pre-IPO equity with no easy way to spend it.
In May 2026, investment banker Storm Duncan listed a Mill Valley estate for $8 million, accepting exclusively Anthropic shares. Another San Francisco property hit the market on May 28 accepting either Anthropic or OpenAI shares. The Brooklyn seller, working with the Barak Blackburn Team, reportedly drew direct inspiration from these Bay Area precedents.
Anthropic’s secondary market valuation now exceeds $1 trillion. That means early employees and investors are, on paper, extraordinarily wealthy. Until the company goes public or gets acquired, those shares are essentially illiquid. Real estate sellers are positioning themselves as a liquidity exit for tech workers who are rich but cash-poor, betting that the shares they receive will eventually convert into real money worth significantly more than the property they’re giving up.
Bitcoin at the grown-ups’ table
The listing has been active in some form since at least August 2025, suggesting the seller has been testing the market for a while. Adding alternative payment options like Anthropic shares and Bitcoin could be a strategic play to widen the buyer pool after a prolonged marketing period.
Accepting pre-IPO shares means taking on significant counterparty and valuation risk. Anthropic’s trillion-dollar secondary market valuation is based on private trades that don’t carry the price discovery mechanisms of public markets. If the company’s IPO disappoints, or if the AI sector faces a correction, a seller who swapped a $6 million property for shares could find themselves holding substantially less.
A seller accepting Bitcoin can hedge or convert immediately given its public market liquidity and 24/7 price feed. A seller accepting private company stock is, in a very real sense, making a venture capital bet with their home equity.
