Anthropic, one of the leading companies developing advanced artificial intelligence, filed paperwork Monday for a stock market debut that could become the largest IPO in history.

The filing marks a major financial milestone for a company that has helped drive the rapid expansion of generative AI.

It also carries unusual weight because Anthropic’s chief executive has repeatedly warned that increasingly capable AI systems could pose an existential threat to humanity if they are not developed and controlled responsibly.

The filing does not guarantee that Anthropic will proceed with an offering, nor does it establish a final valuation, share price or timeline.

Still, an IPO of this scale would test investor appetite for AI companies at a time when businesses are racing to adopt the technology while regulators and researchers debate its risks.

Anthropic was founded to build safer AI systems and competes with major players including OpenAI and Google. Its public-market debut could give investors a closely watched measure of how Wall Street values both the enormous commercial potential of advanced AI and the safeguards needed to manage it.
