Anthropic, the artificial intelligence company that competes with OpenAI, has taken a key step toward going public. The company confidentially submitted a draft registration statement, known as an S-1, to the U.S. Securities and Exchange Commission, according to a filing made public on Friday.
Why file confidentially
Under SEC rules, companies can file their IPO paperwork under seal if they qualify as an emerging growth company — typically one with less than $1.07 billion in annual revenue. The confidential process lets a company test investor appetite and refine its offering before the full prospectus is made public. Once the SEC finishes its review, the company must file a public version of the S-1 at least 15 days before it begins a roadshow to market the shares.
Anthropic has not yet set a price range or a target date for its IPO. The confidential filing means the company is likely still early in the process, gauging market conditions and institutional interest before committing to a timeline.
Anthropic’s place in AI
Founded in 2021, Anthropic is best known for building large language models that compete directly with OpenAI’s GPT series. The company has raised billions from investors including Google, Spark Capital, and Salesforce, and its valuation has climbed above $15 billion in private markets. A public listing would give Anthropic access to deeper capital markets as the AI arms race intensifies.
OpenAI, Anthropic’s chief rival, has not filed for an IPO and remains private. The two companies have jockeyed for dominance in the fast-moving generative AI sector, each releasing increasingly powerful models and rolling out enterprise tools. Anthropic’s decision to go public suggests it sees an advantage in raising money from a broader pool of investors rather than relying solely on venture capital.
The filing also comes as regulators worldwide step up scrutiny of AI safety and ethics. Anthropic has positioned itself as a safety-focused alternative, publishing a responsible scaling policy and committing to rigorous testing before releasing new models. Those commitments may help it navigate regulatory hurdles as a public company.
What happens next
Anthropic has not said when it expects to complete its IPO. The company will need to satisfy the SEC’s comments on its draft registration statement before it can file a public version and begin marketing the shares. Market conditions — including volatility in tech stocks and the broader economy — will also play a role in timing.
For now, the confidential filing is the clearest signal yet that Anthropic intends to join the public markets. Investors and industry watchers will be watching for the public S-1, which will reveal detailed financial data, risk factors, and executive compensation. That public document, once filed, will offer the first unvarnished look at the company’s finances.
