Anthropic eyes going public as it files official submission to SEC

Anthropic has announced that the company has submitted official documentation to the SEC to start being publicly traded, beating OpenAI to an IPO.

Anthropic’s submission to the SEC consists of a confidential Form S-1. The draft is the first official step to landing on the public stock market (via The Verge). The announcement means Anthropic may beat OpenAI to going public, something both AI startups have reportedly had eyes on for some time.

If the submission is approved upon review, Anthropic’s IPO would be among the most valuable. Rough estimates put the company at a valuation of $965 billion, as of late May. OpenAI, in comparison, sits right at around $852 billion.

What Anthropic sent to the US Securities and Exchange Commission to move towards an IPO is being held confidential until a later date. Anthropic is keeping the number of shares and price under wraps until it’s ready to set things in motion. The details contained within a filing like this would be something unprecedented, considering the nature of an AI startup.

Claude has been steadily improving as a model. A recent update brought Claude Opus 4.8 to the table with significant improvements and features. Even among some setbacks like the recent internal leak that ended in the distribution of Claude’s source code, the company still boasts one of the best-performing models.

Other competitors to Anthropic’s Claude include Gemini, though Google is well beyond filing for an IPO. As performance goes, Gemini 3.5 Flash holds a slight advantage over Claude Opus 4.7, according to some of the most recent numbers.
