Anthropic files – Anthropic says it has filed confidential IPO paperwork with the SEC, keeping details like share count and pricing secret while it waits for the regulator’s review. The move lands days after a $65 billion funding round valued the company at $965 billion, placin
On the same Monday that Anthropic said it is stepping toward the public markets. the key details stayed deliberately out of reach. The company told investors it filed confidential paperwork with the Securities and Exchange Commission to go public. and it said the number of shares it will offer and the stock’s price have not been set yet.
“This gives us the option to go public after the SEC completes its review,” Anthropic said in a statement. “The proposed initial public offering will depend on market conditions and other factors.”
The filing came with a clear sense of timing. Anthropic has been rushing to be first. and it announced its IPO move just days after saying it raised $65 billion in its latest funding round—an event it placed at a valuation of $965 billion. That figure pushed it past OpenAI, which was last valued at $852 billion in March.
Behind the corporate numbers is a product story that has helped fuel Anthropic’s momentum, especially in business environments. The company’s enterprise offerings have been central to its rise. with Claude Code—its coding software—standing out as a major driver. This year, Anthropic has rolled out additional products for businesses, including Claude for Small Business. It also unveiled its latest flagship model, Claude Opus 4.8, just last week.
Financial performance has been rising in parallel. Anthropic said its annual revenue run rate topped $47 billion at the beginning of May, up from $30 billion in April. Its run rate was $9 billion last year.
For market watchers, the move fits into a broader sprint toward IPOs. Anthropic and OpenAI are in a heated race to hit the public markets. and the company’s decision to file paperwork now sets up one of the year’s most closely watched debuts outside of SpaceX. which filed paperwork to go public last month.
But Anthropic’s path to a public-market valuation hasn’t been only about product wins. CEO and co-founder Dario Amodei has tried to distinguish Anthropic from OpenAI by presenting it as safety-first. In April. the company said it was holding back its latest AI model. Claude Mythos Preview. because it was too good at hacking into software. even though it was not designed to do so.
The company’s stance then moved from internal controls to partnerships. Anthropic established a cybersecurity partnership with companies including Amazon. Apple. and Microsoft. giving those tech giants access to Mythos so they could use it to find and fix potential flaws hackers could exploit in their software.
Yet the same safety-first posture has also drawn political friction. The Trump administration has been critical of Amodei’s approach. after President Trump threatened to ban the use of Anthropic’s software across government agencies. That threat followed Amodei saying he wouldn’t allow the Pentagon to use Anthropic’s software for the mass surveillance of Americans or to operate fully autonomous weapons.
The administration’s pressure then escalated on the regulatory and business side. Secretary of Defense Pete Hegseth moved to designate the company a supply chain risk. Anthropic has sued to have the designation removed.
From confidential SEC paperwork to a $65 billion funding round, from product rollouts to a court fight over classification, Anthropic is building an IPO story with two tracks running at once: a rapid push into public markets, and a high-stakes debate over how its technology should be used.
