Anthropic and some shareholders plan to raise up to $64.4 bln in an IPO, filing with the SEC on Tuesday set an indicative price range of $70–78 per share. The company intends to issue 801.4 mln new shares and existing holders will sell 23.6 mln shares; at the top of the range the disclosed shares outstanding imply an equity value of about $1 trillion. The target raise is below SpaceX’s record $75 bln base offering (roughly $86.2 bln including overallotment). Anthropic set the size despite a sharp sell-off in AI-related stocks last week. Market concern that politicians advocating tighter regulation of data centers and related infrastructure could raise costs and constrain AI development is weighing on investor sentiment.
