Anthropic said it confidentially filed its IPO prospectus with the Securities and Exchange Commission, setting up a potentially historic share sale for investors ready to jump into artificial intelligence.
“This gives us the option to go public after the SEC completes its review,” Anthropic said in a statement on Monday. “The proposed initial public offering will depend on market conditions and other factors.”
With its announcement, Anthropic is getting out ahead of rival OpenAI, which is readying its own confidential filing. Elon Musk’s SpaceX has officially filed its prospectus and is gearing up for a roadshow this week, with plans to debut next week.
Anthropic was founded in 2021 by a group of executives and researchers who defected from OpenAI over concerns about the company’s direction. Anthropic is best known for its family of AI models called Claude, which power products like its popular coding assistant, Claude Code.
The company has experienced explosive growth this year, announcing in May that its revenue run rate has ballooned to $47 billion, up from $10 billion in annual revenue last year. Last week, it closed a funding round at a $965 billion valuation, topping OpenAI, which was valued at $852 billion in late March.
Anthropic captivated Wall Street and officials in Washington, D.C., this year by announcing a model called Claude Mythos Preview, which has advanced cybersecurity capabilities. The company released the model to a select group of companies as part of a cybersecurity initiative called Project Glasswing, and it’s been engaging in conversations with senior members of the Trump administration about its capabilities.
Some investors and executives worried that Anthropic’s growth would take a hit after a clash with the Department of Defense earlier this year led to the company’s models getting blacklisted by the Pentagon. But while defense contractors dropped Anthropic to comply with the DOD’s order, the company’s popularity in the private sector only increased, as more businesses adopted its models and AI coding tools.
