A luxury townhouse in Williamsburg, Brooklyn has hit the market for $5.99 million, but the seller is offering an unusual payment option: vested Anthropic shares or Bitcoin.
The property at 3 Wythe Lane spans 4,470 square feet, with four bedrooms, five bathrooms, and a finished basement with 12-foot ceilings. But the real story is what this listing reveals about modern wealth.
The Brooklyn seller, working with the Barak Blackburn Team, was inspired by recent Bay Area precedents. In May 2026, an investment banker listed a Mill Valley estate for $8 million, exclusively accepting Anthropic shares. Another San Francisco property listed on May 28 accepted Anthropic or OpenAI shares.
Anthropic's secondary market valuation now exceeds $1 trillion. Early employees are enormously wealthy on paper but cash-poor due to illiquid shares. Real estate sellers are positioning as a liquidity exit, effectively making a venture capital bet with their home equity.
This listing has been active since at least August 2025, suggesting the seller was testing the market. Adding alternative payment options could be a strategic play to widen the buyer pool.
However, accepting pre-IPO shares carries significant risk. The trillion-dollar valuation is based on private trades without public market price discovery. If Anthropic's IPO disappoints or the AI sector corrects, the seller could end up holding substantially less.
