Anthropic files for IPO with Google as investor and rival

Anthropic has filed for an initial public offering (IPO) on the Nasdaq under the ticker "ANT," testing whether public market investors share the enthusiasm of private backers who valued the AI company at $965 billion. The filing reveals Anthropic's complex financial ties, including commitments to spend at least $110 billion with Amazon, $114.5 billion with Google, and $44.9 billion with Microsoft on cloud computing over the next decade. Major investors include Amazon, Google, and venture firms like Sequoia Capital, which also support rival OpenAI. The IPO highlights how AI funding now intertwines investment, infrastructure contracts, and competition, with Google identified as both a key shareholder and a direct competitor. Anthropic's cloud spending commitments are binding regardless of actual usage, raising questions about concentration risk and dependency on a small group of infrastructure providers.
