Anthropic, the maker of AI assistant Claude, filed for an initial public offering on Monday, formally setting in motion a move that will test investor appetite for one of Silicon Valley’s most closely watched AI companies.
The filing “gives us the option to go public after the SEC completes its review,” the company said in a statement, adding that timing, share count and pricing would ultimately depend on market conditions. Those details have yet to be determined.
The announcement lands just days after Anthropic closed a $65 billion Series H round at a $965 billion post-money valuation, according to the company—putting it ahead of rival OpenAI’s last reported $730 billion valuation, underscoring how quickly the upper tier of AI startups is being repriced.
If it goes ahead, Anthropic’s IPO would place it among a small cluster of heavyweight tech companies expected to hit public markets this year, alongside names like OpenAI and SpaceX, as investors reassess the long-term economics of AI.
Founded in 2021 by former OpenAI executives, including Dario Amodei, Anthropic has built its reputation around safety-focused large language models and positioned Claude as a competitor to ChatGPT.
More recently, the company has been pushing further into enterprise marketing workflows, including tools like Claude Design—an AI system aimed at generating slides, one-pagers and other sales and marketing materials, ADWEEK previously reported, signaling a more direct bid for Madison Avenue budgets.
When reached for comment, Anthropic pointed to its public statement released on Monday.
