[Anthropic's IPO Reportedly Attracts About Six Times Oversubscription] According to Bloomberg, citing sources familiar with the matter, Anthropic PBC's initial public offering (IPO) has attracted about six times the number of shares available for purchase, with investor interest growing in what could become the largest stock offering in history. Company filings show that the Claude AI model developer and its co-founders plan to raise up to $64.4 billion through the IPO and $26 billion through a private placement. Combined, the IPO would surpass SpaceX's IPO to become the largest IPO in history. Sources say bankers have informed potential investors that Anthropic will prioritize existing backers, and some potential buyers may receive fewer shares than expected. IPO details include the possibility that share demand may change.
