美国 Anthropic is reportedly aiming to go public on Nasdaq this October, with a valuation of $2 trillion—overtaking SpaceX's $1.77 trillion valuation from June. It could potentially become the largest IPO in history. But the real focus shouldn't be on that number—it should be on San Francisco. Redfin calculated that the post-IPO equity of current/former employees from OpenAI and Anthropic could theoretically account for 29% of the residential housing stock in the SF metro area. ・OpenAI employees: $135B → 20% ・Anthropic employees: $63B → 9% ・Total residential market value: $692B (2024) It's not that they'll actually buy everything, but for the first time, this city will have to absorb wealth concentration at the scale of a single industry. An IPO doesn’t just print $2 trillion. Housing prices, angel investments, the next wave of startups, and the IPOs after that—that’s the real multiplier effect. Silicon Valley was never transformed by technology itself; it was transformed by the money in the hands of tech company employees.
