New Delhi: AI giant Anthropic has confidentially filed for a U.S. initial public offering, the company said on Monday, edging ahead of rival OpenAI in a closely watched race to reach public markets.

The move sets up an early test of whether investor appetite for artificial intelligence, which has fueled lofty private valuations and talk of potential trillion-dollar listings, will hold up under public scrutiny, and which company gets to set the template for how the fast-growing sector is valued.Anthropic, which makes agentic coding assistant Claude Code, did not disclose the size or the terms of the offering. It last raised $65 billion at a post-money valuation of $965 billion in late May, putting it ahead of OpenAI.

The listing would represent one of the most consequential stock market debuts in years, potentially reshaping benchmark indexes, investor flows and the broader narrative driving U.S. equities.Reuters reported in May that OpenAI was also preparing to confidentially file for a U.S. IPO in the coming weeks. That follows SpaceX’s mega-IPO filing, which is on course to rewrite the record books as the Elon Musk-led company pursues a $75 billion offering at a $1.75 trillion valuation and could begin trading within two weeks.Confidential submissions let companies advance IPO preparations while shielding sensitive financial details from rivals and the public.“Filing shortly after SpaceX allows Anthropic to capitalize on strong investor interest in AI and growth stocks while the window remains favorable,” Kat Liu, vice president at IPO research firm IPOX, said.“Anthropic’s valuation ambitions appear far less aggressive in comparison (to SpaceX) than they might have looked in isolation.”RACE FOR AI DOMINANCE
