While Anthropic and OpenAI aren't yet public, you can track their valuation changes via Microsoft's quarterly earnings as it's invested in both. Microsoft marked up its Anthropic investment by $3.2B and marked down its OpenAI investment -$600M. It seems industry perception has matched valuations. https://techcrunch.com/2026/07/29/microsoft-logs-3-2b-from-anthropic-investment-but-openai-was-a-mixed-bag/
