Anthropic takes its first formal step toward Wall Street
On June 1, Anthropic confirmed it had confidentially submitted a draft Form S-1 to the U.S. Securities and Exchange Commission for a proposed IPO of its common stock. Confidential filing is a common move - it lets a company start the SEC review process while keeping sensitive financials away from rivals and the public until later. The announcement was made under Rule 135, so it's explicitly not an offer to sell shares.
What the filing does and doesn't commit to
The S-1 gives Anthropic the option to go public once the SEC completes its review, but the company was careful to hedge: any actual offering depends on market conditions and other factors, and neither the number of shares nor the price has been set. In other words, the door is now open - but Anthropic hasn't said when, or whether, it will walk through it.
The numbers framing the moment
The filing itself didn't disclose financials, but recent reporting sketches the backdrop, and it's eye-watering:
- Anthropic recently closed a $65 billion financing round at a roughly $965 billion valuation - reportedly edging past rival OpenAI.
- The company has pointed to an annualized revenue run-rate around $47 billion, up sharply over the past year, with Claude Code cited as a standout driver.
Why the whole industry is watching
A potential Anthropic listing would be one of the first chances for public markets to put a real price on the generative-AI boom. Analysts have framed the broader dynamic as a race between Anthropic and OpenAI to reach public markets - and public investors' appetite will be a genuine test of whether sky-high private valuations hold up under scrutiny.
There's also a wrinkle of timing worth watching: this filing came just days before a US government directive disrupted two of Anthropic's flagship models, a pointed reminder that regulatory risk is now part of the AI investment story. For now, the message is simple - Anthropic is getting its house in order for a debut that could help define the sector's next chapter.
