Bloomberg 报道，Anthropic 已邀请机构投资者在其可能估值近 2 万亿美元的 IPO 前质询高管。10 月 14 日的会议之后，最早 11 月 9 日当周启动正式路演，感恩节前上市；按 SEC 规则需在 10 月下旬公布 S-1 文件。OpenAI 则相反，以安全担忧为由排除 2026 年上市，正以约 1.4 万亿美元估值私下寻求至少 300 亿美元融资。
原文梳理了 Anthropic 上市时间线和 OpenAI 的相反选择，读者可以对照两家头部 AI 公司的资本路径差异。
Bloomberg: Anthropic has invited institutional investors to question its executives ahead of the possible IPO they value near $2T.
The Oct 14 session could lead to formal marketing as soon as the week of Nov 9 and trading before Thanksgiving per Bloomberg.
OpenAI went the opposite way, ruling out a 2026 listing over safety concerns and seeking at least $30B privately at about $1.4T.
If the November schedule holds, SEC rules require Anthropic to publish its S-1 by late October, at least 15 days before the roadshow.
