Anthropic has taken its first public step toward Wall Street, filing S-1 paperwork with the U.S. Securities and Exchange Commission for an initial public offering. The company said it plans to trade on Nasdaq under the ticker ANT.
If the market gives it the kind of reception bankers dream about, this could become the biggest public debut yet for an AI developer. Reports cited in the filing suggest the offering could raise as much as $100 billion, which would top the record set by SpaceX earlier this year.
That timing is awkward, in the best possible way. Chief executive Dario Amodei asked the industry in September to slow down AI development for humanity’s safety, and the filing lands in the middle of a wider fight over what advanced models can do when they slip their leash. The company itself says success depends on keeping its models at the front of the pack.
Anthropic’s numbers explain why investors are paying attention. The company last raised $65 billion in May at a $965 billion valuation, while more recent estimates put it at $1.5 trillion after a drop from $2 trillion, according to Reuters. It has also posted huge revenue growth, with $1.16 billion in the first half of 2025, $16.3 billion in the first half of this year, and $16.8 billion in third-quarter revenue it told investors about in mid-October. The catch is the same one attached to nearly every AI giant right now: it is still losing money, with a net loss of $80.7 billion in the first half of 2026.
Anthropic is best known for Claude and the Mythos model, and it is now trying to do something no pure-play AI company has done in the U.S.: publicly file an S-1. That alone sets the tone for what comes next, especially with OpenAI’s own debut reportedly expected in 2027.
My take — AI-written commentary, not fact-checked reporting
Anthropic is doing the classic Silicon Valley two-step: warn loudly about AI danger, then march straight into a blockbuster IPO. It’s not hypocrisy so much as the modern tech playbook, where caution is for the stage and scale is for the cap table. The market will call that maturity; everyone else can call it a very expensive sermon.
