Why Anthropic's Filing Crushed Tech Stocks

The piece argues that Anthropic’s planned IPO exposed how tightly linked the AI industry and major technology companies have become, helping trigger a broad selloff as investors questioned whether the sector’s enormous spending can pay off. Unlike a typical independent company, Anthropic depends on Amazon, Google, Microsoft, and Broadcom as investors, lenders, suppliers, cloud providers, customers, and sales channels. Its filing names Amazon more than 150 times and Google more than 100, a sharp contrast with early IPO filings for Google and Amazon, which described simpler businesses and relationships. Anthropic also has major, long-term commitments to buy computing capacity from its partners, while those partners rely on its growth to support their own cloud revenues and investment values.

This web of mutual dependence, the author contends, makes the supposed competitors resemble parts of a single holding company. Google reportedly holds about 15% of Anthropic and Amazon 10-12%; Google’s filings show $117 billion in unrealized gains on private-company investments, mainly from one company, which the author identifies as Anthropic. Such stakes may weaken incentives to compete aggressively: Google or Amazon could damage the value of their investments by undercutting Anthropic, while Anthropic and OpenAI depend on those same firms for infrastructure and financing. The piece connects this structure to policy choices that encouraged cross-investment and abandoned efforts to limit overlapping ownership. With AI firms and their suppliers burning cash, the author warns that a falling valuation for Anthropic could threaten the wider network, not merely one company.
