Anthropic has filed a registration statement to list its shares on the Nasdaq exchange, formally kicking off the process toward an initial public offering. Investors and analysts following the filing say the deal could end up being the largest IPO ever completed, reflecting how central the company has become to the AI boom over the past few years.
Anthropic was founded in 2021 by former OpenAI researchers and has built the Claude line of AI models, which compete directly with OpenAI's ChatGPT and Google's Gemini. The company has grown quickly by selling access to its models to businesses and developers, and has drawn major investment from large technology partners along the way. A public listing would give ordinary investors their first chance to buy shares directly in one of the handful of companies widely seen as leading the frontier of AI development.
News of the filing rippled through markets within hours. All three major US stock indices closed higher on the news, and the reaction was even sharper in Asia, where South Korea's KOSPI jumped roughly 4 percent and chipmakers Samsung Electronics and SK Hynix both rallied, on the view that a successful Anthropic listing would validate continued heavy spending on AI infrastructure and the chips that power it.
The filing comes at a delicate moment for AI investment broadly. Markets have spent recent weeks worried about whether the enormous, often debt funded spending on AI data centers and chips can be justified by the revenue AI companies are actually generating today. A filing of this size, from a company seen as a genuine technology leader rather than a speculative startup, gave investors a reason to look past those worries, at least for now.
Attention now turns to pricing details, expected valuation, and timing for the listing, along with how rivals including OpenAI respond to a competitor going public first.
