Amazon and Google hold combined stakes valued near 400 billion dollars in Anthropic, according to documentation published regarding the artificial intelligence company’s upcoming initial public offering.
New filings reveal that Amazon’s total participation approaches 20 percent, though a self-imposed ownership limit caps its direct share at 12 percent, with the remaining balance held as convertible bonds. That total stake carries a valuation of approximately 258 billion dollars based on the proposed midpoint range for the public offering, originating from an investment of about 18.6 billion dollars, as elpais.com reported.
Google maintains a stake close to 10 percent of the capital, valued at 132 billion dollars against an investment of roughly 33 billion dollars. Google’s ownership is capped at 14.99 percent, restricting how rapidly it can convert future bonds. Neither tech giant will hold voting rights in the company led by Dario Amodei, avoiding regulatory hurdles from antitrust authorities.
Nvidia holds a participation close to 3 percent of the capital, joining Microsoft and various venture capital funds including Capital Group, Coatue, D1 Capital, GIC, ICONIQ, Blackstone, Brookfield, Fidelity, General Catalyst, Insight Partners, Lightspeed Venture Partners, Spark Capital, Bessemer Venture Partners, MGX, T. Rowe Price, and Temasek.
These entities contributed to financing rounds, culminating in a 65 billion dollar raise in May. Meanwhile, the seven co-founders retain a combined stake near 13 percent, maintaining control via Class F shares granting them 50.1 percent of the voting rights.
Operational disclosures highlight substantial infrastructure spending agreements between the artificial intelligence firm and its major backers. Anthropic committed to spending at least 121 billion dollars with Google Cloud through July 2033, alongside an additional 150 billion dollars in compute capacity utilizing TPU chips from Alphabet’s subsidiary.
The startup also agreed to invest at least 110 billion dollars in Amazon’s cloud division through 2036, alongside a 49 billion dollar commitment to Microsoft through 2033 and a 120.5 billion dollar agreement with SpaceX through 2029.
Microsoft and Google are participating in a private placement running parallel to the public offering, where the startup aims to raise 26 billion dollars alongside contributions from AMD, Broadcom, Micron Technology, Nvidia, and TSMC. The company listed OpenAI and Alphabet as primary competitors in its S-1 filing. Enterprise competition intensified as new Claude workplace tools launched to challenge Microsoft Office and Google Workspace.
