Anthropic Confidentially Files for IPO, Racing OpenAI to Go Public

Anthropic 秘密提交 IPO 申请，与竞争对手 OpenAI 赛跑上市

Anthropic confidentially filed IPO documents and plans to list on Wall Street as early as this fall; the filing does not disclose the number of shares to be offered or the price range.

Why it matters: HKR-H/K/R all pass: a leading foundation-model lab confidentially filed for an IPO, with a fall target reported. Foundation-model IPOs sit in the 95–100 band; share count and pricing are not disclosed.
