Anthropic has filed confidentially with the US Securities and Exchange Commission for an initial public offering, marking one of the most anticipated moves in the artificial intelligence industry. The company confirmed its filing but has not yet released financial details or a proposed timeline, as confidential submissions allow companies to work through regulatory review without exposing sensitive commercial information until the offering is closer.

The filing sets up a potentially historic period for US flotations. SpaceX, the dominant commercial space launch provider, has also filed for what is expected to be a record-breaking IPO. OpenAI, the high-profile ChatGPT developer and one of Anthropic's closest competitors, has reportedly been planning a public offering later in 2026. The convergence of these names suggests that investors may soon have a rare chance to own shares in some of the private sector’s most valuable AI and technology businesses.

• Anthropic has agreed to pay about $1.25bn per month for data centre capacity in a deal involving SpaceX’s Colossus facilities.

Long road to Wall Street

Going public is not an overnight process. Companies file a registration statement with the SEC, answer comments from regulators, choose an exchange, and market shares to institutional investors through a roadshow before pricing. A confidential filing adds another layer of discretion. Anthropic's paperwork is subject to SEC review, and the public may only see the key sections when the company releases its preliminary prospectus. The process can take months, and there is no guarantee that a listing will occur on a specific timetable.

An unusual AI candidate

Anthropic's path to public markets differs in meaningful ways from the consumer-ready image of AI labs that many people associate with ChatGPT. Founded in 2021 by former OpenAI researchers, including Dario and Daniela Amodei, Anthropic was built around safety research and a corporate structure intended to prioritize long-term responsibility over short-term growth. It has retained that identity even as it expanded into commercial products and massive computing requirements.

While OpenAI captured mainstream attention with its viral chatbot, Anthropic concentrated on making Claude useful for software developers, financial analysts, legal teams, and other business users. That narrower focus has produced a loyal customer base and a reputation for reliability in complex workplace scenarios. Claude has become one of the most widely used coding assistants in enterprise settings, competing with tools offered by Microsoft, Google, OpenAI and others.

Claude’s momentum

Product momentum has been building for more than a year. In the autumn, Anthropic’s Claude Opus 4.5 model began gaining significant ground in developer communities, largely because of its performance in writing code and handling long, complicated documents. Enthusiasts praised its ability to stay within context and follow intricate instructions, prompting more engineering teams to build on top of the company’s API.

More recently, Anthropic drew wider public attention when it said its unreleased Claude Mythos model was substantially better than existing tools at discovering security vulnerabilities in computer systems. The claim, if verified through real-world deployment, could expand the company’s addressable market far beyond coding and customer support. Anthropic said it worked with banks and government agencies to patch critical systems before Mythos is released. That kind of trust-based, safety-oriented relationship is central to Anthropic's pitch to the public market.

Revenue and profitability questions

Anthropic has grown at a pace that few companies can match. Last month, reports said that its quarterly revenue was on track to more than double from the prior quarter and that surging demand could give Anthropic its first profitable quarter for the three months ending in June. The milestone would represent a major transition for a research-driven company that has consumed enormous amounts of investor capital.

Still, profitability may not become the new normal. Anthropic is simultaneously ramping up spending on computing infrastructure, model training, and staff. AI labs are in a global race for data centre capacity, advanced
