Anthropic Confidentially Files for IPO After Raising $65B at $965B Valuation

Anthropic filed confidentially for an initial public offering, TechCrunch reported. The filing follows a $65 billion private fundraising round completed last week at a $965 billion valuation that drew more investor interest than available shares. Co-founder Daniela Amodei told attendees at the Bloomberg Tech conference on Thursday that the move is driven by capital needs.

“It’s a really big upfront cost to train the models and to serve inference on them,” she said. She added that frontier AI companies will increasingly require public-market access for sustained funding. The company’s annualized revenue crossed $47 billion in May, up from roughly $9 billion at the end of 2025.

Amodei said current use cases in coding, financial services, legal work, and health care will remain the main sources of efficiency gains while businesses continue to learn how to integrate the tools. Anthropic has chosen not to build its own data centers. 25 billion per month, according to SpaceX’s S-1 filing.

Amodei said the partnership reflects a preference for matching capacity to actual demand rather than risking overcommitment. “We would much prefer to be on the side of having a little bit more demand for the product than we’re able to serve than the inverse,” she said.

She noted that Anthropic’s longstanding approach has been to plan for strong outcomes without purchasing more compute than it can use productively.
