A tech banker is offering his $4.8M California estate in exchange for Anthropic shares as the company’s valuation hits $1 trillion

Storm Duncan, founder of tech boutique investment bank Ignatious, listed his fully furnished 13-acre Mill Valley estate with an infinity-edge pool and sweeping views of San Francisco on Zillow, offering to trade it for Anthropic shares as the company's secondary market valuation reached $1 trillion. Duncan, who already owns some Anthropic shares from its 2024 funding round and wants more exposure after implementing Claude Code at his firm, said he has already received multiple serious offers from Anthropic employees and early investors who are sitting on illiquid stock they cannot sell until the company goes public. Duncan noted that small investors like himself cannot buy in directly and that secondary market deals have become increasingly opaque and fee-laden as share scarcity has driven up demand.
