Anthropic has unveiled an updated draft prospectus and is preparing to launch the roadshow for an initial public offering that aims to raise up to $64.4 billion, according to simultaneous reports from Reuters and CNBC on Nov 10. The draft sets an initial price range of $70 to $78 a share, with final terms expected shortly. Anthropic and some existing investors plan to sell shares in the offering. At the top of the range, the IPO alone would rank among the most closely watched tech listings in years.
The numbers: IPO plus private placement, up to $90.4 billion in total
Besides the IPO, Anthropic plans to raise $26 billion through a separate private placement from cornerstone investors including Google, Nvidia and AMD. Counting contributions from other cornerstone investors such as Broadcom, Micron, Microsoft and TSMC, the total size of the share sale could reach $90.4 billion.
| Offering component | Size ($bn) | Pricing/notes |
|---|---|---|
| IPO | Up to 64.4 | $70-$78 per share |
| Private placement | 26 | Cornerstone investors including Google, Nvidia, AMD |
| Total | Up to 90.4 | Includes contributions from Broadcom, Micron, Microsoft, TSMC |
Analysis: cornerstone lineup maps AI supply-chain ties
The cornerstone roster spans the core links of the AI supply chain, from cloud services and GPUs to chip manufacturing and memory. The arrangement appears to provide funding for the offering while also reflecting how deeply large-model AI companies are tied to upstream computing and chipmakers.
The disclosure followed a brief reversal. On Nov 9, Reuters reported that Anthropic planned to raise as much as $69.3 billion in the IPO. Shortly after distributing copies of a securities filing stating a $69.3 billion target to banks, Anthropic withdrew the document, saying its pricing details were inaccurate and that it would update the filing. The latest draft lowers the IPO ceiling to $64.4 billion and specifies the $70-$78 range, a difference from the earlier version. With both figures now on record, the final size will depend on the updated filing.
CNBC noted that Anthropic's IPO is expected roughly five months after Elon Musk took SpaceX public in a record offering. If it proceeds smoothly, it would mark a landmark in the capitalization of large-model AI companies, with both its size and cornerstone lineup carrying significant weight for the market.
What to watch: final pricing and allocation of proceeds
Key questions remain: where Anthropic's final offer price lands within the $70-$78 range; how the $64.4 billion IPO and $26 billion private placement break down; and how much each cornerstone investor ultimately contributes. Those details await the formal update to the prospectus and the announcement of offering terms.
