Anthropic Pulls Ahead of OpenAI in High-Stakes Race for IPO Riches

Anthropic filed confidential IPO paperwork on Monday, and the title says it has pulled ahead of OpenAI; the RSS snippet does not disclose valuation, fundraising size, or an IPO timetable.

Why it matters: Anthropic’s confidential IPO filing is a major foundation-model company capital-markets milestone; HKR-H/K/R all pass. Valuation, raise size, and listing timeline are not disclosed, keeping it below the top edge.
