Artificial intelligence giant Anthropic filed papers on Monday for what could be the biggest initial public offering of stock ever, even as its top executive warns that advanced AI could pose an existential threat to humanity, the Associated Press reported.

The filing sets up the San Francisco company for a Wall Street debut next month, potentially eclipsing the SpaceX initial public offering in June that raised a record $86 billion — yaani $8,600 crore. An Anthropic listing would also put the company ahead of rival OpenAI in going public, in what is expected to be a pair of blockbuster stock debuts for the rival AI labs, according to the AP.

In its listing documents, Anthropic warned that increasingly powerful AI systems could, without appropriate safeguards, oversight and security measures, pose 'catastrophic or existential risks to humanity', the BBC reported. The BBC said the company plans to list on the Nasdaq under the ticker symbol ANT, and that it has not yet disclosed how many shares it intends to sell or an indicative price range.

The 335-page document showed Anthropic's revenue is growing rapidly, but the company behind the Claude chatbot has yet to turn a profit: it reported a net loss of $80.7 billion — yaani $8,070 crore — in the first half of 2026, compared with a loss of $13 billion in the same period a year earlier, the AP reported. The BBC reported revenue of $16.3 billion for the first half of the year.

Anthropic was valued earlier this year at $965 billion by private investors, and that value is reportedly set to rise to $1.5 trillion or possibly $2 trillion, although its final valuation has not been established, according to the AP. At $1.5 trillion, Anthropic would rank among the world's most valuable public companies, alongside Tesla.

The filing comes weeks after chief executive Dario Amodei argued in an essay for slowing the development of the most advanced AI models, the AP reported. An IPO could provide Anthropic, a five-year-old startup, with enormous resources to accelerate its expansion, even as its own documents warn investors about the risks of the technology it is building.
